2.1 Installation Guidelines
•
Before connecting any wires determine the router’s cable route throughout
the home or vehicle/boat, both to and from the inverter.
•
Always check for existing electrical, plumbing, or other areas of potential
damage BEFORE drilling or cutting into walls to mount the router.
Make sure all wires have a smooth bend radius and do not become
•
kinked.
If installing this router in a boat, RV, or truck ensure the conductors
•
passing through walls, bulkheads, or other structural members are
protected. This minimizes insulation damage such as chafi ng, which can
be caused by vibration or constant rubbing.
2.2 Tools Required
Installing the router is a simple process and requires the following tools:
• Phillips screwdriver • Level • Drill
• Cut-out tool (knife/saw) • Pencil • Drill bit (7/64”)
2.3 Installation Overview
The ME-RTR is required in order to parallel stack the MS-PAE Series inverter/
charger. Each inverter/charger must be connected directly to the router using
the supplied CAT 5 and RJ11 communication cables. DO NOT substitute for
the supplied cables. The router comes with four 6 ft. CAT 5 cables and four 6
ft. RJ11 communication cables rated at 300 VAC – which is required to meet
NEC/CEC codes when installing the router in a Magnum Panel system.
Each paralleled inverter/charger requires a CAT 5 high speed communication
cable to be connected to the router’s parallel stacking ports marked MA (Master), SL1 (Slave 1), SL2 (Slave 2), and SL3 (Slave 3). One inverter/charger
will always be designated the Master, and subsequently any other connected
inverter/chargers will be designated as Slaves. You can stack up to four MSPAE Series inverter/chargers using one router.
The router must be located close to the inverter/chargers (within fi ve feet) and
acts as the system control panel. If a remote monitoring location is required,
a ME-RC50 or ME-ARC50 may be connected to one of the communication
ports (P1-P6) on the router, and will act as a remote on/off switch and assist
in monitoring the system.
Info: It is recommended that you set up the master inverter/
charger as the fi rst unit on the left so that the CAT 5 and
communication cables are connected to the inverter/chargers
in order from left to right – MA (Master), SL1, SL2, and SL3.
This confi guration makes it easy to identify the master and slave
units without having to trace the wires from the router to each
inverter/charger.
Select an appropriate location to install the router.
2.
Mount the router base to the wall using the 4 screws provided. See
Figure 2-3.
Info: If the router is being installed on a Magnum Panel en-
closure (MP), it can be attached to either the left or right-hand
side using the bracket (ME-RTR-B) provided. Refer to the MP
manual (PN: 64-0028) for information on mounting the router
on a MP panel.
Connect a communication cable to the Remote port on every inverter
1.
installed in parallel (see Figure 2-5), using the supplied remote cables.
Route the inverter-connected communication cables from each inverter/
2.
charger to your router. Follow the same route you used for the CAT 5
cables.
Connect each communication cable to its respective communication port
3.
on the router. (P1-P6 for the appropriate number of inverters installed in
parallel.) Refer to Section 2.6.1 and Figures 2-7 through 2-9.
Connect any accessories to the remaining open communication ports
4.
on the router.
Info: It is recommended that the Master inverter be connected
to remote communication Port 1, Slave 1 to remote communication Port 2 etc., in order to more easily keep track of which
inverter is displayed on each port.
Info: It is recommended that all accessories be connected
directly to the router using any available communication ports
(P1-P6). Except for remotes (i.e., ME-RC or ME-ARC), if there
are additional accessories to connect, but all the router’s communication ports are being used, the additional accessories may
be connected to the Network ports on the stacked inverter/chargers. Any accessory connected directly to the Network port on
an inverter/charger will display as an accessory on the router
port to which the inverter/charger is connected.
Example: A ME-AGS-N connected to the Network port on the
master inverter (P1) will display as P1Acc on the router.
Info: Multiple accessories of the same type may be connected
to the system, but there are some limitations to the number
of accessories. You may connect a maximum of one ME-RC or
ME-ARC remote, two ME-AGS-N modules, and any number of
ME-BMK/ME-BMK-NS accessories.
Info: The ME-ARC or ME-RC remote must be connected directly
to the router and programmed to indicate which port the remote
is monitoring. It is recommended that the ME-RC or ME-ARC
is set to monitor “System” in most installations. The ME-RC
or ME-ARC must not be directly connected to the Remote or
Network ports on the MS -PAE inverter when the router is also
connected.
Info: When used in conjunction with a router, a ME-RC or ME-
ARC has limited functions. The remote control monitors the port
it is designated to display, turns all parallel inverter/chargers
on/off, and displays METER and TECH information. The ME-ARC
does not control the inverter/chargers via the CTRL button.
You can either surface mount or conceal the cable connections to the router.
The cables can be fl ush mounted through an opening in a wall (Figure 2-7);
or, if there is insuffi cient room behind the wall or no desire to cut into the
wall, the cables can be surface mounted (Figures 2-8).
Figure 2-7, Concealed Mounted Communication Cables
Figure 2-8, Surface Mounted Communication Cables
Info: The CAT 5 and communication cables may be installed
on the mounting surface or through the wall. If the cables are
installed on the surface, the router cover has cutout sections to
accommodate the cables (see Figure 2-9). These cutout sections
are made thinner to allow them to be easily broken or cut. Only
remove those cutout sections needed for the number of cable
connections you are installing.
The Aux Relay is a 2-wire dry contact relay that is either normally open or
closed. The Aux Relay may be wired to any device requiring a contact closure that draws no more than 0.1 amp of current. The Aux Relay is a voltage
controlled relay and may be programmed to open or close on VDC, with an
adjustable delay.
CAUTION: When wiring the Aux Relay, use an inline 0.5 amp
fuse to protect the relay. Damage to this relay is not covered
by warranty.
Once all the wiring is completed, you are ready to install the router cover.
Tip the top of the cover down and hook it over the router top (protruding
horizontal tabs on inside top of cover go under corresponding mounting tabs
at top of router), and then drop the cover down (cover the router’s bottom
vertical tabs). Install the two fl athead Phillips screws into the bottom tabs to
hold the router cover in place.
Install with two flathead Phillips
mounting screws

2.9 Power-up Routine
When the router is first connected to an inverter, a power-up routine is
initialized. During the power-up routine, the LCD displays “MAGNUM ENERGY ROUTER Ver x.x”. The next three screens prompt you to set HOURS, MINUTES,
and AM/PM. Once the clock has been set, the router displays the SYSTEM HOME screen.
Info: Pressing and holding down the METER button for three
seconds takes you back to the System Home screen from any
menu.
When a router is connected to a Magnum inverter/charger, the settings in the
router determine the inverter/charger’s operating parameters. The router’s
default settings are adequate for most installations; however, you have the
option to change some of the operating parameters. This section shows you
how to navigate the router and gives you an understanding of the function of
each adjustable setting. See Figures 4-1 thru 4-9 for complete maps of the
router’s menu items and adjustable settings.
*** IMPORTANT ***
All settings/setup menus in the router are compatible with MS-PAE Series
inverter/chargers. If you are using the router with another inverter/charger
(other than the MS-PAE Series), some features and setup menus may not
be compatible with your inverter and will not function. Contact Magnum
Energy to determine if a particular feature/setup menu provided in the
router is compatible with your inverter.
3.1 Navigating the Router
Familiarize yourself with the controls on the front panel which are used to fi nd,
adjust, and save the desired settings (refer to Figure 1-1). They are:
• LCD Display - The 4-line LCD display shows status and info for the inverter/
charger and any attached accessories. All setup menus and faults also appear
on the LCD display.
Info: The LCD display returns to the System Home screen to show
system status after 5 minutes if no buttons have been pressed.
Info: When the “←” (left facing arrow) symbol is shown on the
screen it indicates that the displayed setting has been selected
and will be used.
• MenuPushbuttons (x5) - These buttons allow simple access to menu
items that can help with confi guring, monitoring, and troubleshooting your
inverter/charger system.
• Rotary SELECT Knob - This rotary knob allows you to quickly scroll through
and select various menu items and settings. Pressing the knob selects the
menu item to change, or saves the current selection. Refresh the LCD display
by holding the rotary knob down for seven seconds.
Info: The LCD screen features a 4-line display. If there are
more choices than will fi t on the screen, up and down arrows
are present to guide you in accessing those choices. An up arrow
indicates you must rotate the SELECT knob counterclockwise to
display the next line. A down arrow requires a clockwise rotation.
If both an up and down arrow display, rotate the SELECT knob
clockwise or counterclockwise to display all hidden lines.
The fi ve pushbuttons (PORT, CTRL, METER, SETUP, and TECH) located beneath
the LCD screen allow the inverter/charger system to be confi gured to your
specifi c preferences. These pushbuttons also allow you to access menu items
that can help with monitoring and troubleshooting your system.
3.2.1 PORT Button
The PORT button scrolls between the six communication ports on the bottom
of the router. Each parallel inverter/charger must be connected to a communication port in order to be programmed and to display status info.
Info: You must be on a Home screen menu (“Home” appears
in bottom right corner of router’s LCD display) in order for the
PORT button to scroll through all the active ports. If you are not
on a Home screen, pressing the PORT button will only display
devices that are related to the screen you are currently viewing
(only true for METER, SETUP, and TECH button menus, PORT
button does not work from CTRL button menus).
Info: Pressing and holding down the METER button for 3-seconds
takes you back to the System Home screen from any menu.
Any remaining open ports may be used to connect Magnum accessories such
as an ME-AGS-N, ME-BMK/ME-BMK-NS, and an ME-RC or ME-ARC remote.
Info: You can connect a maximum of four inverter/chargers
to a router. If the maximum number of inverter/chargers are
connected, two open ports remain. If more ports are needed
for accessories, the Network port on each inverter/charger may
also be used for accessories.
Info: When an accessory is plugged into a communication port
on the router, the PORT button displays the accessory as the
corresponding port (i.e., Port 5 would show “ME-AGS-N”). If an
accessory is plugged into the Network port on one of the parallel
inverter/chargers, the PORT button will display the accessory
as “P#Acc” (i.e., a ME-AGS-N plugged into a parallel inverter/
charger that is plugged into Port 1 would display as “P1Acc”).
The CTRL button contains the menus for 01 AC In Control, 02CHG Control,
and 03Gen Control (an AGS must be connected in order for the Gen Control
menu to display). The CTRL button gives you quick control of the main functions
of the inverter/charger without having to access the SETUP menus in order
to change the operation of the inverter/charger or the generator. Once the
settings have been programmed in the SETUP menus, the features can then
be enabled using the CTRL button.
Example: The SETUP menu’s 02C AC In - Time setting is used to set what
time of day (e.g., 12AM to 8AM) you want the inverter to connect to the
incoming AC. Once this time is set, use the CTRL button to access the
AC In Control menu item and select Time Connect. When Time Connect
is selected, the inverter/charger will only connect to AC when the time
is between 12AM and 8AM.
The 01AC In Control menu has four different conditions in which the
inverter/charger will connect to incoming AC power. Only one condition may
be selected at any one time – multiple conditions can be enabled, but only
one can be active.
Info: Before the inverter allows the AC input to connect to the
AC source (grid or gen), the incoming AC must be qualified by
the inverter/charger (voltage is below the high AC input require-
ments, above the VAC Dropout setting, and between 50 Hz to
70 Hz for domestic models – 40-60 Hz for export models).
Info: The top status line of the LCD display alternates the
inverter/charger status with a secondary AC IN status when
AC is present, but is not connecting as a result of a selection
made in the SETUP menu.
•
Auto Connect: Automatically connects to incoming AC power.
•
VDC Connect: Connects to incoming AC when the DC battery voltage
is below the Set Connect Volts setting in the 02D AC IN VDC menu.
Disconnects from incoming AC when the DC battery voltage is above the
Set Disconnect Volts setting, also in the 02D AC IN VDC menu.
Info: See SETUP menu 02D on page 28 for a complete
explanation of the Set Connect Volts setting.
•
Time Connect: Connects to incoming AC when the time of day is between
the Set Connect Time and Set Disconnect Time settings per the 02C AC
In - Time menu.
Info: See SETUP menu 02C on page 27 for a complete
explanation of the Set Connect Hour/Minute/AM-PM setting.
AC In - Disabled: Disconnects incoming AC when selected. This setting
•
will prevent incoming AC from connecting to the inverter/charger.
Example: AC is present, but Time Connect has been selected from the
01 AC In Control menu, and the current time of day is 6PM. The 02C AC
In-Time menu’s current setting is 2AM - 8AM. The current time of 6PM is
outside the connect time, so the inverter/charger will not connect to the
incoming AC until after 2AM. The primary status will display “Inverting”
and the secondary status will display “Time Connect” to let you know the
02 CHG Control allows you to set the Charger mode to Multi-Stage, Force
Float, or to Restart Bulk. Most of the time the charger should be left in the
Multi-Stage setting, but to override this setting use the CTRL button and the
CHG Control menu. The charger can be forced into the Float mode or you
can start the Bulk mode using the Force Float or Restart Bulk settings from
the CTRL button’s 02 CHG Control menu item.
•
Multi-Stage: This charge profi le starts in Bulk mode (maximum cur-
rent). It transitions to the Absorption stage (constant voltage). When
the Absorption voltage is reached (as determined by the SETUP menu’s
03E Absorb Done setting), it fi nally transitions to the fi nal charge stage
as selected in the SETUP menu’s 03G Final Charge Stage menu item.
Info: Multi-Stage must be selected in order to use the fi nal
charge stage selected in the 03G Final Charge Stage menu.
Force Float: This charge profi le forces the charger to stay in the Float
•
mode as long as AC is present and the charger is active. Force Float is
most often used when another source of charging such as PV, wind, or
hydro is available to keep the batteries at or above the fl oat voltage. If
AC is disconnected and then reconnected the charger will go directly to
the Float mode, and will not initiate a Bulk or Absorption charge cycle.
CAUTION: Using the Force Float setting may not fully charge the
batteries. Most batteries require a Bulk and Absorption charge
cycle in order to fully recombine the electrolyte in the batteries
and bring the specifi c gravity to the proper level. Be sure to check
with your battery manufacturer before using this setting.
Info: If Silent is selected from the 03G Final Charge Stage menu,
you can override this selection with Force Float to temporarily
fl oat the batteries.
Restart Bulk: This selection restarts the Bulk cycle from any stage in
•
the charge cycle. The Restart Bulk setting is useful when a full Multi-
Stage charge cycle does not bring the specifi c gravity of the batteries
to the proper level.
Info: The Restart Bulk setting automatically defaults back to
the Multi-Stage setting once the inverter/charger status displays
“Bulk Charging”.
Info: If you have to continually restart the Bulk cycle in order
to bring the batteries to full charge, check the settings from the
SETUP button’s 03 Charger Setup menu items to make sure the
batteries are fully charged at the end of a regular Multi-Stage
charge cycle. Check with your battery manufacturer for proper
battery charger settings.
CAUTION: Frequently restarting the Bulk cycle may result in
03 Gen Control is used for controlling a standby generator that is connected
to the system and using the optional ME-AGS-N module. Once the ME-AGS-N
is installed in the system, the generator can be manually started and stopped,
or set to start and stop automatically from the Gen Control menu.
Info: An ME-ARC must be directly connected to one of the
router’s communication ports in order to be used (in a remote
location) to control a generator that is connected to an MEAGS-N.
Info: When the ME-ARC is connected directly to the router, the
CTRL button function of the ME-ARC is defeated. However, the
ME-ARC does contain the Gen Control selection in its FAVS menu.
This allows the generator to be controlled via the ME-ARC through
the FAVS menu, but not through the CTRL menu.
Info: The ME-AGS-N must be installed in order for the 03 Gen
Control menu to control a standby generator. Refer to the ME-
AGS-N manual (PN: 64-0039) for more information on controlling
standby generators.
OFF: The OFF selection will stop the generator by sending a ‘stop’
•
command from the ME-AGS-N control module (can be running from
either a manual start or an autostart command). When the OFF setting
is selected, the generator will not start automatically.
Info: If DC power is lost to the router, this menu resets to the
default OFF position for safety.
•
ON: The ON selection will start the generator by sending a ‘start’ com-
mand from the ME-AGS-N control module. Once the generator is start-
ed, it may be stopped by selecting OFF from the 03 Gen Control menu,
which sends a stop command from the ME-AGS-N.
Info: You can manually start and automatically stop a connected
generator by selecting ON from the Gen Control menu, and then
change the selection to AUTO. When the AUTO setting is selected
after the generator has been manually started, it will use the
stop setting in either the SETUP button’s Set Stop Gen Volts or
Set Max Gen Run Time menu items, whichever occurs fi rst.
Info: The ON selection uses warm-up time. The OFF selection
stops immediately and does not use the cool-down time.
AUTO: This selection uses the settings in the 04 AGS Setup menus to
•
automatically start and stop the generator based on battery voltage,
time of day, AC load on the inverter, high temperature, or battery state
of charge (requires a ME-BMK/ME-BMK-NS accessory). Refer to the 04
AGS Setup section on page 37 to set the start and stop parameters for
the generator.
The METER button gives you access to different meters which help determine
the status of the inverter/charger and battery system.
Info: Some METER functions may not be accessible with older
inverter software. If some meters do not function, check for
current inverter software.
Info: Most displays automatically return to the System Home
screen fi ve minutes after the last button push. When using the
METER button, the selected menus stay and do not return to
the Home screen. This feature is useful for displaying commonly
used meter readings.
Info: Pressing and holding down the METER button for 3 seconds
takes you back to the System Home screen from any menu.

01A DC Volts: DC Volts provides the battery voltage. The DC Volts
•
display provides the voltage from the battery bank connected to the
inverter. Accuracy is ±1.5% with a 0.1 VDC resolution.
01B DC Amps: While inverting, the DC Amps reading displays a negative
•
number to show the battery current used by the inverter. If in Charge
mode, this setting displays a positive number to show the amount of
current delivered to the batteries. The accuracy of this display below 1
amp AC (~10 amps DC @ 12VDC) is not detected. When the current in
or out of the batteries is greater than 1 amp AC, the display accuracy
is ±20%.
01C Charge Time: This meter displays whenever the charger is in the
•
Bulk or Absorb mode. The meter does not accumulate time when in
Float, Charger Standby, Full, or Silent mode.
Info: Once the charger leaves the Absorption mode and
enters the fi nal charge stage, this timer is reset and will not
accumulate until the charger reenters the Bulk or Absorption
charge mode.
02 AC Meters
02A Output Volts: This menu provides the AC voltage measurement at
•
the inverter’s output terminals. If inverting, this measures the inverter’s
output voltage. If in Charge mode, this measures the AC voltage that is
passing through the inverter from the source (e.g., grid or generator).
02B Output Hz: While inverting, this menu displays the output frequency
•
of the inverter. When the incoming AC source is connected to an inverter,
this meter displays the frequency of the incoming AC source (i.e. grid or
generator) that is passing through the inverter to the inverter’s output
terminals. The frequency is shown in Hertz (Hz).
•
02C Load Amps: This menu displays the load the inverter is running in
AC amps – measured at the inverter’s output terminals. This number is
always displayed as a positive number.
•
02D Input Amps: This menu displays the total AC amps being used by
the inverter for charging, and any connected load at the output of the
inverter.
Example: If the charger is using 20A from the AC source and the load
connected to the inverter output is using 10A, the combined load on the
incoming AC source is 30A. So, 30A would be displayed as the input amps.
•
02E Inv/Chg Amps: While charging, this menu displays the amps the
charger is using from the AC source. When inverting, this menu displays
the current of the load the inverter is powering.
Info: The 02E Inv/Chg Amps value is determined by subtracting
the 02C Load Amps value from the 02D AC Input Amps value.
03A AGS Status: If there is no Automatic Generator Start (ME-AGS-N)
•
module connected, the status will read “No Comm”. If there is a ME-AGS-N
connected, please refer to the ME-AGS-N owners manual (PN: 64-0039)
for information on the status messages.
Info: These menus allow the optional ME-AGS-N (Auto Gen Start
-Network version)
— if installed — to display the status of the
generator. Refer to the ME-AGS-N Owner’s Manual (PN: 64-0039)
for detailed information on the AGS and these menus.
03B DC Volts-AGS: This menu displays the DC voltage measured at pins
•
3 and 4 of the ME-AGS-N module. This menu is useful in setting up the
voltage start for the AGS, and for troubleshooting its operation.
Info: The DC voltage reading in this menu may vary from the
DC voltage readings in the 01A DC Volts and 04C DC Volts-BMK menus. Each DC voltage reading is taken at a different
place in the system, and therefore there may be wire losses or
connections that make the readings differ. It is important when
troubleshooting the system to read the appropriate related meter
for each device. When troubleshooting the AGS, use the 03B DC Volts-AGS menu item for verifi cation and testing purposes.
03C Gen Run Time: This menu displays the amount of time the
•
generator has been running since the AGS auto-started the generator.
This menu does not display run time when the generator has been
manually started.
Info: This hour meter resets each time the generator is stopped.
This is useful when trying to determine how long the generator
has been running in Auto mode if you were not present when
it started. This meter does not replace the hour meter for total
hours the generator has run.
03D AGS Temp: This menu displays the temperature of the AGS temp
•
sensor (included with ME-AGS-N, but use is optional), and is helpful in
determining proper placement and operation of the AGS temp sensor.
03E Since Gen Run: This menu displays the number of days since the
•
generator has last run. This menu is useful in determining if the AGS
start and stop settings are set up correctly.
Info: This meter resets whenever the generator is either auto-
started, exercised, or manually started. The meter reads the
B+/run signal provided by the generator to the AGS module.
04 BMK Meters
These menus display the status of the battery system from the optional
ME-BMK/ME-BMK-NS, if installed. Refer to the ME-BMK/ME-BMK-NS Owner’s
Manual (PN: 64-0013) for detailed information on the Battery Monitor Kit

•
of the battery. The read only display shows the State of Charge (SOC)
for the connected battery bank. The SOC represents the condition of the
battery as a percentage of the available capacity left in the battery.
Range is 0% to 100%, where 100% represents a fully charged battery
and 0% means the battery is completely discharged.
If no % displays, there are 3 status menus to determine what state the
BMK is in:
Pwr-up Fault - The battery monitor faulted when it was powered-up.
The fault occurred because the power-up self-test failed.
No Comm - This indicates the ME-BMK/ME-BMK-NS is not communicating
with the router. The most common causes are: no ME-BMK/ME-BMK-NS
installed in the system, a bad network cable, or no power to the MEBMK/ME-BMK-NS.
Think’n - The battery monitor is connected and actively monitoring the
battery system. The router displays “Think’n” (or “n’k“in some screen
displays) to indicate that the SOC reference point is being calculated.
After the batteries are fully charged, the display changes from “Think’n”
to “100%” and begins to provide accurate SOC percentage values.
04B DC Volts - BMK: This meter displays the real-time battery voltage
•
from 07.00 to 70.00 volts (± 0.02 volts).
04C DC Amps - BMK: This meter displays the real-time charge current
•
(amps into the battery), or the discharge current (amps out of the
battery). Charging is shown as a positive (+) number and discharging is
shown as a negative (-) number. The range is from ±0.1 to 999 amps,
with a 1.0% accuracy.
04D AH In/Out: This meter displays the amp-hours returned to or
•
removed from the battery. When this value is positive, it represents
amp-hours returned to the battery during any subsequent charging. A
negative value represents amp-hours removed from a full battery. Its
range is ±32768 AH.
O4E Resettable AHrs: This meter displays the total amp-hours
•
removed from the battery since it was last reset. This display can be
used as a battery load indicator to help determine and monitor the
battery load consumption. Its range is 0 to 6,553.50 amp-hours (0.1
amp hour resolution).
04F Total kAHrs Out (Total Amp-Hours Removed): This meter
•
displays the total amp-hours removed from the battery since the Sense
Module was fi rst connected. This display can be used as a battery
service life indicator. The value is displayed in 0.1k [or 100 amp-hours
(“k” equals 1000)] resolution up to a maximum of 6,553.5k amp-hours
(6,553,500 amp-hours). The displayed number resets to 0.0k when the
Sense Module is disconnected from power.
04G Minimum VDC: This menu displays the lowest battery voltage
•
since the last reset. The voltage shown on the display is averaged each
second and is helpful when troubleshooting or detecting an over-discharge
condition.
•
04H Maximum VDC: This menu displays the highest battery voltage
since the last reset. The voltage shown on the display is averaged each
second, this allows you to check your charging system (battery charger,
charge controller, etc.) to ensure the charging voltage has been attained.
This display is also helpful when troubleshooting or detecting if an overcharge condition has occurred.
Pressing the SETUP button provides access to the menu items and settings
that enable you to confi gure the router display, the inverter/charger, and any
connected accessory. Review each menu item to determine if you need to
adjust any settings to meet your system requirements.
Info: The fi rst screen that may appear when the SETUP button
is pushed is a password screen. If the PIN has been set under
the TECH button’s SETUP PIN menu item, the fi rst screen is the

The following menus are used to set up the router screen and clock.
01A Set Time: The router contains a real time clock that must be set
•
for proper operation of some features. These features are: the SETUP
button’s 02C AC In-Time, 04B Gen Run Time, 04G Quiet Time, 04H Gen Exercise, and the Fault History menu items under the TECH button.
**IMPORTANT**
It is very important that you set the time clock as it is a critical piece in
effectively addressing fault issues, as well as for the proper start/stop
functions of your AGS device, if installed.
Info: The clock obtains power from the inverter and will reset if
the router is disconnected from the inverter.
To Set the Current Time
From the Set Clock menu:
Rotate the SELECT knob to the hour of day, and then press
1.
SELECT.
Rotate the SELECT knob to the correct minute setting, and then
2.
press SELECT.
Rotate the SELECT knob to the appropriate AM or PM setting, and
3.
then press SELECT.
01B Display: This setting adjusts the contrast and brightness of the
•
LCD screen based on the current lighting conditions and viewing angle.
Default settings - Contrast = 100%, Brightness = 50%
01C Power Save: This setting turns off the Power Save™ feature, or
•
selects the time (from off to 60 minutes) that determines when the
display goes into Power Save mode. This setting also allows the Port LEDs
to be turned “off” or set to “Auto” mode. In Auto mode, the Port LEDs
automatically blink whenever a device is connected to a router port.
Default setting - PowerSave [min] = 15, Port LEDs = Auto
What is the Power Save feature? The Power Save feature turns off the
LCD backlight and the LEDs on the router to conserve energy. The router
goes into Power Save mode if there hasn’t been a button press or fault
message for a period of time (this time is determined by the SETUP menu’s
01C Power Save setting). Whenever the router goes into the Power Save
mode, the LCD backlight and the LEDs can be reactivated by pressing any
button. If you have a fault during the Power Save mode, the LCD backlight
and the FAULT LED will come on and stay on as long as the fault is present.
Info: If you want the LCD backlight and LEDs to always be on,
you will need to turn the Power Save feature off by selecting
PowerSave [min] = off.
Info: If you want the Port LEDs to always be off, you will need
to set the Port LEDs to Port LEDs = off.
01D Temp Display: This menu item selects whether to display
•
temperatures in Fahrenheit or Celsius. Once you select either Fahrenheit
or Celsius, the following menu items will appear with this selection:
03D AGS Temp, 04E Gen Run Temp, and 01 Temperatures under the
TECH button.
Default setting - Fahrenheit
01E Viewing Ports: The Viewing Ports menu item sets the main screen
•
to either automatically scroll through each connected port, or requires you
to manually select each port by pressing the PORT button. Adjusting the
seconds allows you to select how long the Port screen is displayed before
it automatically scrolls to the next screen. Range is off-60 seconds.
Default setting - Auto Roll (sec) = off
01F Aux Relay State: Selections are Open, Auto, and Close.
•
Open - Manually opens the Aux Relay contacts. This setting manually
controls the device connected to the Aux Relay, or tests the Aux Relay
operation.
Auto - Uses the Relay Close and Relay Open settings from the 01G Aux
Relay V Trip menu, and the Close Delay and Open Delay settings in the
01H Aux Relay Timing menu to automatically control the Aux Relay.
Closed - Manually closes the Aux Relay. This setting manually controls the
device connected to the Aux Relay, or tests the Aux Relay operation.
Default setting - Open
Info: When the open or closed selections are made, the Aux
Relay will open or close without any time delay.
01G Aux Relay V Trip: This menu sets the Battery Voltage Trip point to
•
open and close the Aux Relay contacts. Once the battery voltage reaches
the trip point, the relay will open or close once the time set in the 01H Aux Relay Timing menu item is satisfied.
Relay Close - Set this voltage to close the Aux Relay contacts. This range
can be below or above the Relay Open setting depending on if you want
the Aux Relay to be Active Low or Active High.
Range is 8-17 (12 VDC), 16-34 (24 VDC) and 32-51 (48 VDC)
Relay Open - Set this voltage to open the Aux Relay contacts. This range
can be below or above the Relay Close setting depending on if you want
the Aux Relay to be Active Low or Active High.
Range is 8-17 (12 VDC), 16-34 (24 VDC) and 32-51 (48 VDC)
Default settings - For both the Relay Open and Relay Close settings:
14 (12 VDC), 28 (24 VDC) and 56 (48 VDC).
Example - Active Low: Set the Relay Close voltage below the Relay
Open voltage. If the Relay Close voltage is set at 12.0 VDC and the
Relay Open voltage is set at 14.5 VDC, the relay would close when
the battery voltage dropped to 12.0 VDC and open when the battery
voltage rises to 14.5 VDC. This configuration might be used to control
a battery exhaust fan or as a simple PV charge controller.
Example - Active High: Set the Relay Open voltage below the Relay
Close voltage. If the Relay Open voltage is set at 12.0 VDC and the
Relay Close voltage is set at 14.5 VDC, the relay would open when
the battery voltage dropped to 12.0 VDC and close when the battery
voltage rises to 14.5 VDC. This configuration might be used to control
a low voltage disconnect circuit for a DC load.
01H Aux Relay Timing: This setting delays the automatic closing and
opening of the Aux Relay contacts after the Relay Open and Relay Close
settings have been satisfied.
Close Delay - Use this setting to delay the close of the Aux Relay contact
once the Voltage Trip point has been reached. This sets a hysteresis so
the Aux Relay does not cycle unnecessarily. Range is 0-240 secondsOpen Delay - Use this setting to delay the opening of the Aux Relay
contact once the Voltage Trip point has been reached. This sets a
hysteresis so the Aux Relay does not cycle unnecessarily. Range is 0-
240 seconds
Default settings - Close Delay and Open Delay: 10 seconds
Auxiliary (Aux) Relay
The router contains a 2-wire dry contact Aux Relay. The Aux Relay can be
manually opened or closed, or is voltage driven and can be set to either close
on low DC voltage and open on high DC voltage, or to close on high DC voltage
and open on low DC voltage. The relay can be set to the Auto position where
it will read the open and close voltage settings with delay times, or it can be
manually either forced closed or open.
What is the Aux Relay used for? The most common use is to turn on an
exhaust fan to eliminate your battery bank gasses using the VDC start and
stop settings. The Aux Relay can also be used to control the coil of a current
carrying relay.
How do I adjust the Aux Relay? The three menus used to adjust the Aux
Relay are the 01F Aux Relay State, 01G Aux Relay V Trip, and 01H Aux Relay Timing menus. These three menus are used to select the operating state of the
Aux Relay (menu 01F), the DC voltage at which the Aux Relay automatically
opens and closes (menu 01G), and the delay timing on open and closing of
the Aux Relay (menu 01H).
Aux Relay LED - The Aux Relay LED will illuminate in an amber color if the
relay is active (closed) in the programmed state.
Example: The Aux Relay is set to Auto in menu 01F. The 01G Aux Relay V
Trip’s Relay Close setting is 12.0 VDC and the Relay Open setting is 14.5
VDC. The 01H Aux Relay Timing menu’s Close Delay and Open Delay settings are 10 seconds.
When the battery voltage reaches 12.0 VDC after a 10 second delay, the
Aux Relay will close and the LED will illuminate amber. When the battery
voltage reaches 14.5 VDC after a 10 second delay, the Aux Relay will open
and the Aux Relay LED will turn off.
The following menus 02A - 02D are used to set up only the functions related
to the Inverting mode of the inverter/charger.
•
02A Search Watts: Allows you to turn off the Search Watts feature, or
to adjust the power level to determine when the inverter leaves Search
mode. The power level range selection is Off, 5W to 50W. If this feature
is not needed, select Search=Off. When search is turned off, the inverter
continuously provides full AC voltage to the loads.
Default setting - Search= 5W.
Info: When the Search Watts feature is active, “Searching”
appears on the top line of the LCD display and the green INV
LED will slowly fl ash.
What is the Search Watts feature? This feature is used to help save
battery power by reducing the inverter’s output to search pulses when there
is no detectable load. If a load greater than the wattage level setting turns on
while the inverter is ‘searching’, the inverter will start ‘inverting’ to provide
full voltage on its output.
Should I use the Search Watts feature? If the inverter can spend a great
deal of time searching (to reduce the power drain on your batteries) and you
can tolerate small loads (less than fi ve watts) being OFF, then the Search
mode feature should be used. However, if some small loads (i.e., digital
clocks, satellite receivers, answering machines, etc.,) are required to be on,
then this feature should be turned off (Search = Off).
Where should I set Search Watts? The Search Watts setting should be
adjusted to the same power level (or the next lower setting) of the smallest
load that you want to run. If you don’t know the wattage of the smallest load
you want to run, turn the switch for the load on and decrease the Search Watts
setting until the load comes on and stays on.
Example: You have reviewed all the loads you want to run and determined
that the smallest load is a 30 watt light. Set Search = 30W. Whenever you
turn on any load (because all the loads are greater than 30 watts), the
inverter will stop searching and start inverting to deliver power to the load.
Note: Even though the Search Watts feature is on, some connected equipment
may draw enough current even while turned off to keep the inverter in the
Inverting mode.
02B LBCO Setting: The Low Battery Cut-Out (LBCO) sets the DC voltage
•
level that turns off the inverter. This helps protect the batteries from
over-discharge damage. Selections are from 9.0 VDC to 12.2 VDC (12volt inverter models), 18.0 VDC to 24.4 VDC (24-volt inverter models),
or 36.0 to 48.8 (48-volt inverter models). If the battery voltage drops
below the LBCO set-point continuously for more than 1 minute, the FAULT
LED will come on, the inverter will turn off, and the display will show a
‘Low Battery’ status. If the battery voltage falls below 8.5 volts (12-volt
models), 17.0 volts (24-volt models) or 34.0 (48-volt models), the FAULT
LED and ‘Low Battery’ status will be immediate.
Default settings: LBCO = 10.0 VDC (12-volt models), 20.0 VDC (24-
volt models) or 40.0 VDC (48-volt models).
Info: The inverter automatically begins inverting when the DC
voltage increases to ≥ 12.5 VDC (12-volt models), ≥ 25.0 VDC
(24-volt models), or ≥ 50.0 VDC (48-volt models). If AC power
is available and connected to the inverter’s input, the inverter
will automatically clear the low battery fault, pass the input AC
power to the output, and begin charging the batteries.
Where should I set the LBCO setting? If you want to cycle the batteries
slightly but don’t want to discharge them more than 20%*, then the
LBCO setting should be set from 11.5 to 12.2 VDC (12-volt models), 23.0
to 24.4 VDC (24-volt models), or 46.0 to 48.8 (48-volt models). In some
applications, such as those installed in an off-grid home or when doing a lot
of dry-camping in your RV, you may want to cycle down to 50%* by setting
the LBCO from 10.0 to 11.4 VDC (12-volt models), 20.0 to 22.8 VDC (24-volt
models) or 40.0 to 45.6 VDC (48-volt models). In extreme circumstances,
you have the ability to discharge the batteries to 80%* by setting the LBCO
to 9.0 or 9.5 VDC (12-volt models), 18.0 or 19.0 VDC (24-volt models), or
36.0 or 38.0 VDC (48-volt models) before recharging.
* These discharge percentages are rough estimates; for accurate battery
monitoring, a battery monitor such as Magnum’s ME-BMK/ME-BMK-NS is
required.
Info: The higher the LBCO setting, the less the inverter will
discharge the batteries; which should allow the batteries to have
a longer life. The down side to a higher LBCO setting is that you
need to charge more often to prevent the inverter from shutting
off in Fault mode.
Info: If there is an ME-AGS-N installed, it should be set to start
≥1.0 volts higher than the LBCO setting – this is to prevent the
inverter from shutting down before the generator comes on.
02C AC In-Time: This feature allows you to connect to the local power
•
utility at a predetermined time of day. When the current time falls within
the set times, the inverter/charger connects to the AC that is connected
to the AC input terminals. Once time passes outside the set times, the
inverter/charger disconnects from the AC source. If your local power
utility offers ‘time of day billing,’ this feature may save you money by
only connecting to the utility when rates are the least expensive.
Default setting - 6:00A - 6:00P
What is the AC In-Time feature? This feature allows the incoming AC to
connect to the inverter/charger and charge the batteries only during the time
of day as set in the 02C AC In-Time menu. Even if AC is present on the AC
input terminals of the inverter/charger it will only connect during those times
that were previously set up.
Should I use the AC In-Time feature? The most common use of AC In-
Time is when your local utility company offers peak rate savings. Peak rate
savings are when the utility company offers a lower rate per kWh (kilo Watt
hour) on your power bill, usually at night when there is less demand on the
local utility grid.
Where should I set AC In-Time? Check with your local utility company or
installer and see if they offer lower rates at particular times of the day. If a
lower rate is offered, try setting your connect time to coincide with the utility
companies lower rates, this will save you money.
Example: The standard rate on your power bill is $.10 kWh. Your utility
company offers $.08 KWH between 12:00 AM and 7:00AM. Set your
connect time to coincide with the utility company’s lower rates in order
to save money when using utility power to charge the batteries.
•
02D AC In VDC: The AC In VDC setting determines when the inverter/
charger connects to incoming AC based on VDC (battery voltage). AC In
VDC is set within a range of battery voltages; the fi rst being the connect
DC voltage at which the inverter/charger will connect to incoming AC, and
the second being the disconnect DC voltage at which time the inverter
will disconnect from incoming AC. This setting is used when an alternate
charging source(s) is present. The alternate charging sources may be
PV, wind, and/or hydro. Typically, the AC In VDC setting optimizes the
alternate charging source(s) and only uses the grid to charge the batteries
if the alternate charging source is not able to maintain the batteries above
What is the AC In VDC feature? This feature allows the incoming AC to
connect to the inverter/charger and charge the batteries once the set voltage
value in the 02D AC In VDC menu is reached. Even if AC is present on the AC
input terminals of the inverter/charger, it will only connect to incoming AC
when the Set Connect Volts setting is reached. It will disconnect when the
Set Disconnect Volts voltage setting is reached.
Should I use the AC In VDC feature? The most common use of AC In VDC is
when you have an alternate source(s) of battery charging. The most common
sources of alternate battery charging are PV, wind, and/or hydro. These sources
are directly connected to the batteries via a charge controller. In order to
optimize the alternate charge source(s), the incoming AC must be prevented
from connecting to the inverter/charger or else the inverter/charger will take
over charging the batteries and the alternate source will not be used.
Where should I set AC In VDC? Check with your battery manufacturer
or installer in order to determine the correct settings for your batteries.
Typically, battery manufacturers don’t recommend discharging the batteries
below 50%, which when related to a voltage setting is approximately 12.0-
12.2 VDC, 24.0-24.4 VDC and 48-48.8 VDC for 12, 24 and 48 volt battery
systems respectively.
Example: In order to protect the batteries from over-discharging, set
the connect voltage at 12.2 VDC, 24.4 VDC, or 48.8 VDC respectively. If
the alternate charge source cannot keep the battery charged, then the
grid will connect at 12.2 VDC and charge the batteries. You would set
the disconnect voltage at the Absorb voltage for your batteries to make
sure the batteries received at least a 75-80% charge before the AC is
disconnected.
02E Parallel Threshold: This setting programs when the slave inverters
turn on as a result of the power being provided by the master inverter.
In order to keep from overcurrenting the master inverter before the
slave inverters can turn on and provide more power to run loads, the
master inverter should not be allowed to reach the full output capacity.
This setting is expressed in a percentage of power being provided by
the master inverter.
Info: When the Parallel Threshold setting is reached, all
connected slave inverters turn on at the same time to deliver
maximum power to the loads. After approximately 30-seconds
running to stabilize the AC current, the slave(s) that are not
needed will shut down and the units that are still inverting will
share the AC current equally.
Example: There are 3 MS4024PAE units in parallel (1- Master, Slave #1,
and Slave #2) with a total capacity of 12kW and the Parallel Threshold
default is set to 60%. The master inverter is running a 2000W load which
is below the 60% threshold (4000W x .6 = 2400W). A 1000W load is
added so the total load on the system is now 3000W, which exceeds
the ParallelThreshold setting of 2400W. Slave #1 and #2 inverters will
turn on, delivering up to 12000W total power. Within approximately 30seconds, the system will shut down Slave #2, and the master and Slave
#1 will each run 1500W (sharing the 3000W load equalling between
them). Now the 1000W load is turned off so the total system load is
2000W. Slave #1 will now turn off and the master inverter will be running
the 2000W load.
Default setting - 60%
Should I use the Parallel Threshold feature? This depends on the
application. Most applications set a threshold level such that the connected
slave inverters come on only when they are required to power the loads. This
reduces the power drain on the batteries because the slave inverters that are
not actively powering the loads are in standby.
If you have a load larger than the capacity of the Master inverter and the
startup current is needed very quickly, you may need to turn the threshold
setting OFF. This will ensure all the stacked inverters are always on to meet
the fast startup current requirements of this large load.
Where should I set Parallel Threshold? Where you set the threshold
depends on your typical AC loads and how much time you would like the
master inverter to run (versus the slaves). If you want the master inverter
to run as much of the loads as possible before the slave(s) turn on, then set
the threshold at a higher setting. If you want the slave(s) to share more of
the load, then set the threshold to a lower setting.
Example: Your loads are typically under 4000W and you have a 3-
inverter parallel system. You want the master to run loads up to 3000W
before the slave inverters turn on. You would set the Parallel Threshold
to 75% (4000W x .75 = 3000W). The master inverter will now run any
load up to 3000W before the slave inverters turn on. In this scenario,
if a 5000W load was turned on the slave inverters would turn on, and
then Slave #2 would turn off, and the master and Slave #1 would each
run at 2500W.
03A AC Input Amps: This selection ensures that the combined current
draw from the charger and the AC loads does not exceed the maximum
input current that is available. Whenever the utility or generator is
connected to the inverter, the current used to power the AC loads and
to charge the batteries is monitored. When the total current used to
power the AC loads and charge the batteries begins to approach the
AC Input Amps setting, the current used for charging the batteries is
automatically reduced. This ensures the AC loads have all the available
current when needed.
Default setting - Amps = 30 Amps
Where should I set AC Input Amps? Set the AC Input Amps setting
to match the current rating of the utility power or the generator’s circuit
breaker. If using multiple AC sources (utility and generator) through an
AC transfer switch, adjust this setting to the smaller AC breaker size. This
setting is dependent on the stability of the AC source. If using a generator,
factors such as altitude and output voltage regulation may require a lower
setting than the generator’s breaker size. For best performance, lower this
setting to 1/3 its rated capacity and gradually increase it while ensuring the
voltage level stays above the 03D VAC Dropout setting.
CAUTION: The AC Input Amps setting does not limit the current
to the inverter loads. If the current from the loads on the output
of the inverter are greater than the circuit breaker rating on the
incoming AC source, you may experience nuisance tripping on
this breaker.
Info: This setting controls the input current differently
depending on the inverter/charger model and the AC input wiring
confi guration selected for your particular model. ME, MS and
RD Series models have 2 AC inputs (HOT IN 1 and HOT IN 2).
AC Input Amps is only monitored on HOT IN 1 on these models
when wired as a dual-in/dual-out confi guration. On these models,
if a single-in/single-out confi guration is selected and HOT IN 1
and HOT IN 2 are jumped together, then set the AC Input Amps
setting to 1/2 the input breaker size as 1/2 the current will pass
through HOT IN 1 and HOT IN 2 simultaneously.
If MS-AE or MS-PAE models are used, these models have HOT IN
1 and HOT IN 2 and the current on both inputs are monitored.
Set AC Input Amps to match the input breaker size on these
models.
•
03B Battery Type: Used to select the battery type, which determines
the battery charge profi
proper charge voltage. The fi xed voltage selections are GEL (for Gel
batteries), Flooded (for liquid lead acid batteries), AGM 1 (for Lifeline
AGM batteries), and AGM 2 (for East Penn/Deka/Discover/Trojan
AGM batteries). The Custom selection allows the Float, Absorb and
Equalization charge v
Table 3-1 to determine the specifi c charge voltage based on the battery
type selected.
Info: The voltage settings shown in Table 3-1 are based on the
Battery Temperature Sensor (BTS) having been at a temperature
of 77° F (25° C), or not connected. If the BTS is connected, the
actual charge voltage will increase if the temperature around
the BTS is below 77° F (25° C), and decrease if higher than 77°
F (25° C). This ensures the batteries receive the correct charge
voltage regardless of temperature.
Note 1: Voltage same as absorption voltage – to prevent equalization.
Note 2: Specifi
cations for Concord (Lifeline Series) AGM batteries.
Note 3: Specifi cations for East Penn, Deka, Discover and Trojan AGM batteries.
Note 4: When using the Custom setting, the EQ (Equalization) voltage
adjustment cannot be set lower than the Absorb Voltage setting. Also, the
EQ Voltage adjustment cannot be set higher than 2-volts (12-volt systems),
4-volts (24-volt systems), or 8-volts (48-volt systems) above the Absorb
voltage setting.
•
03C Max Charge Rate: Sets the maximum charge r
ate allowed to
charge the batteries during Bulk, Absorption, Float, and Equalize
charging. Selections are Max Charge = 0% up to Max Charge = 100%.
The Max Charge = 0% setting is available to help minimize charging
while continuing to allow pass-through power. The rest of the selections
are provided to limit the charge rate to the battery bank, which helps
prevent battery overheating caused by charging at too high a charge rate.
The maximum charge selections are provided as a percentage of the
inverter/charger’s maximum charging capability. Refer to the label on
the side of the inverter or the owner’s manual for the inverter/charger
to determine its maximum charge rate. Once you fi nd this maximum
charge rate, determine the percentage needed to limit the charge rate
to your battery bank.
Example: The charger is rated for 120 amps, and you need to limit the
charge rate to 72 amps. Choose the Max Charge = 60% selection (72
amps = 60% of 120 amps).
Default setting - Max Charge Rate = 100%
Info: If the Max Charge Rate setting is 0%, the topology of the
Magnum inverter (when connected to an AC source) will override
the 0% setting and start charging if the battery voltage is <12
VDC (12 VDC models), <14 VDC (24-volt models), or <28 VDC
(48-volt models).
How do I determine where to set my maximum charge rate? The
maximum charge rate is generally set to a C/5* rate (C = the total amphour capacity of the battery bank – using the 20-hour AH rate). The C/5 rate
is usually used when the objective is to charge the batteries as quickly as
possible (i.e., 400 AH ÷ 5 = 80 amp maximum charge rate). A lower rate such
as C/20* is used when the batteries need to be charged as slow as possible.
* C/5 or C/20 rate - charge rates are commonly expressed as a ratio of the total
amp-hour (AH) capacity of the battery bank. For example, with a 400 AH battery
bank (C = 400), the C/5 charge rate is 80 A (400/5 = 80 A).
CAUTION: The C/5 or C/20 charge rate settings are guidelines;
they are not requirements on how you should set your battery
charge rate. For specifi c charge rate requirements, refer to your
battery manufacturer.
Info: If multiple inverter/chargers are used on a single battery
bank, you must ensure that the total charge rate from all
inverter/chargers is limited to the maximum charge rate needed
for your battery bank. The Max Charge Rate setting only limits
the charging on each inverter/charger individually, not on all
inverter/chargers.
•
03D Low VAC Dropout: Selects the minimum AC voltage that must be
present on the input before the inverter/charger switches from Inverter
mode to Charger mode.
This setting also determines the minimum AC voltage threshold where
the charger disengages and the inverter (when turned on) provides AC
power from the batteries. This protects AC loads from utility outages.
Example: If this value is set to 60 VAC, then the AC input voltage must
be above 60 volts before the inverter will switch from Inverter mode to
Charge mode.
Where do I set my VAC Dropout? It depends on the application and what
you are using as the AC source. The settings not only look at the incoming
voltage level to determine when to transfer, but also determines how quickly
the charger disconnects and starts inverting based of the fl uctuations of the
incoming AC voltage.
Dropout = 60 VAC to 100 VAC (For export models: Dropout = 120
VAC to 200 VAC) - Use a Low VAC Dropout setting of 60 VAC to 100 VAC
(export models: dropout from 120 VAC to 200 VAC) when the AC source
may have fl uctuations in RMS voltage. These settings attempt to prevent
the charger from disengaging unnecessarily due to poor quality voltage
and are highly recommended if using a generator for charging. The
transfer time from Charge mode to Inverter mode is >16 milliseconds
when using these settings.
Dropout = UPS Mode - Use the UPS Mode setting when the AC source
is well regulated above 105 VAC (210 VAC for export inverter models)
and the inverter loads are sensitive to voltage fl uctuations. This setting
is intolerant of voltage fl uctuations and will provide a quick transfer. The
transfer time from Charge mode to Inverter mode is ≤16 milliseconds
when using this setting. Do not use this setting if using a generator as
your AC source.
Info: If you get nuisance AC disconnects, either change the
setting to 100 VAC or less (export inverter models: 200 VAC or
less), or obtain a better voltage regulated AC source.
•
03E Absorb Done (Time, Amps, SOC): This setting determines whether
time, amps, or SOC are used to determine when the second stage of
battery charging, or Absorption Stage, is fi nished and transitions to
the fi nal charge stage (see 03G Final Charge Stage). Absorption is the
second stage of the charge process and the batteries will be almost fully
charged.
Info: If the Absorb stage is short or terminated, the batteries
may not receive a full charge. In contrast, if the Absorb stage
is too long the batteries may be overcharged. Either scenario
may lead to damage to the batteries. Contact your battery
manufacturer to ensure the best charge settings are used for
your type of batteries.
Set Absorb Done Time - Set Absorb Done Time is used when a specifi c time
is determined to be the best solution for ending absorption time. When using
time, the battery bank size will typically determine the length of the absorb
time setting. Taking specifi c gravity readings of the batteries and adjusting
the absorb time may be needed in order to obtain the appropriate absorb time
for your battery type and battery bank size. The larger the battery bank the
longer the absorb time to ensure the batteries receive a full charge, or you
can use Table 3-2 to select the setting – as a general rule of thumb.
Default Setting - Absorb Done Time = 2.0 Hrs
Table 3-2, Battery Amp/Hrs Capacity to Suggested Absorb Time
Set Absorb Done Amps - This setting is used when the DC amperage
supplied to the batteries (i.e., return amps) is used to determine when
the batteries are fully charged. During the Absorb charge mode, the
return amps from the charger slowly decreases. When this current
decreases below the Absorb Done Amps setting, the charger transfers
from the Absorb charge cycle to the fi nal charge stage (Float or Silent
charge mode).
Most battery manufacturers use a specifi c formula to determine the
return amps that indicate a full charge for their particular type of battery.
The formula used by most manufacturers to absorb the batteries is
C/20, where C=Battery Bank’s Total Amp Hours. Basically, they take
approximately 5% of the total battery bank size, and consider the
battery totally charged when the charger’s return amps drop to this
level. Continuing to charge past this level may possibly overcharge the
batteries. Check with your battery manufacturer in order to determine
the correct return amp settings for your batteries.
Default setting - Absorb Done Amps = 20 ADC
Info: Setting the Absorb Done Amps menu item to 0 (zero) will
keep the charger in the Absorb charge mode until the 03F Max
Charge Time setting is reached (if no BMK installed).
Info: When using the Absorb Done Amps setting the charger will
stay in the Absorb charge mode for a minimum of two minutes
– independent of the actual Absorb Done Amps setting.
Info: If DC loads are connected directly to the batteries, it is not
recommended that you use the Absorb Done Amps setting. DC
loads cause the charger to increase amperage delivered to the
battery bank in order to charge the batteries, plus run the DC
loads. This scenario could result in overcharging the batteries
since the return amps reading will be skewed by the DC loads.
Info: It is highly suggested that you install a battery monitor if
the Absorb Done Amps setting is used. If a battery monitor is
not installed, the Absorb Done Amps setting relies on the METER
menu’s 01B DC Amps value to determine when to transfer out
of the Absorb charge mode. When a ME-BMK/ME-BMK-NS is
installed, the Absorb Done Amps setting relies on the METER
menu’s 04C DC Amps – BMK value to determine when to transfer
out of the Absorb charge mode. This is the most accurate DC
amperage measurement. The DC amps reading from the MEBMK/ME-BMK-NS is accurate to +/- .1 ADC.
Set Absorb Done SOC: This setting can be used if a ME-BMK/ME-BMK-
NS is installed and you want to use the SOC (State of Charge) of the
battery bank to determine when the batteries are fully charged. The
SOC is the best way to determine when the batteries are fully charged.
The SOC also is helpful because any DC loads or other charge sources
connected to the battery bank will not affect the SOC reading, and the
batteries will always receive a full charge.
Info: A ME-BMK/ME-BMK-NS is required in order for the Absorb
Done SOC setting to be used. If the Absorb Done SOC setting
is selected and there is no ME-BMK/ME-BMK-NS installed in
the system, then the Absorb Done SOC setting will be based
on the value selected in the SETUP menu’s 05B AmpHour Size
menu item.
Info: If the Absorb Done SOC setting is used when charging
from a generator source, then it is recommended that a setting
of less than 100% be used (usually around 90% is acceptable).
This lower setting is used because running the generator past
the 90% setting is sometimes considered an ineffi cient use of
fuel. If a setting lower than 100% is used, then at least once a
week the batteries should be charged to 100%, to make sure
damage is not done to the batteries by not bringing them to a
full charge state.
03F Max Charge Time: The Max Charge Time setting is the maximum
•
time the charger will operate in either the Bulk or Absorption mode. Once
the charger reaches the max charge time, it will transition to the fi nal
charge stage as set in the SETUP menu’s 03G Final Charge Stage.
Default setting - Max Charge Time = 12.0 Hours
Info: In order to ensure a complete charge cycle is accomplished,
adjust the Max Charge Time setting to a higher value than the
settings in the following SETUP menu items; 03E Absorb Done
Time, 03E Absorb Done Amps, and 03E Absorb Done SOC. The
Max Charge Time setting has priority over these menus and will
stop the charge cycle once that setting is satisfi ed.
Example: The Max Charge Time setting is six hrs, but the 03E Absorb
Done Time setting is eight hrs. The charge cycle will stop after six hrs as
per the Max Charge Time setting, and not fi nish the Absorb Done Time
setting of eight hrs.
03G Final Charge Stage: The Final Charge Stage setting is the stage the
•
charger will transition to after the Absorption Charge stage is completed
(as set in the 03E Absorb Done menu item). There are three choices for
the fi nal charge stage: Multi-Stage, Float, and Silent.
Info: The Final Charge Stage menu item is only used when
Multi-Stage is selected in the 02 CHG Control menu item.
Default setting - Set Final Charge Stage = Multi-Stage
Set Final Charge Stage = Multi-Stage - The Multi-Stage setting
transitions from the Absorption stage to Float. Once in the Float stage
for four hours with no DC load on the batteries, the charger will enter the
Full Charge stage. In the Full Charge mode, the charger automatically
goes into a Standby mode (stops charging but is still on and active)
and monitors the battery voltage. The charger will remain in the Full
Charge stage until the battery voltage drops below 12.7 VDC for 12v
batteries, 25.4 VDC for 24-volt batteries, and 50.8 VDC for 48-volt
batteries – at which time it will return to the Float stage. These battery
voltages are the fully charged voltages of a battery at rest. The charger
will continue to cycle between Float and Full Charge as long as incoming
AC is available.
Info: The Full Charge stage will help reduce water consumption in
fl ooded batteries during long charge cycles. If another charge source
such as PV or wind is charging the batteries above the fully charged
voltage, the charger will remain in the Full Charge mode.
Why should I use the Multi-Stage? Multi-Stage is the most commonly used
charge mode. It is suitable for most applications and will assure a full charge
to the batteries, without overcharging. If there is another alternate charge
source charging the batteries such as PV, wind or hydro, then Multi-Stage mode
will use the inverter/charger to complete a full charge. The inverter/charger
will transition to Full Charge mode and the alternate charge source will then
maintain the battery voltage. If the alternate source is unable to maintain
the voltage, the charger will enter Float mode for another four hour period.
The Full Charge feature in the Multi-Stage mode also helps reduce water
consumption in fl ooded batteries when they are left in the Charge mode for
extended periods, such as in a backup power application.
Set Final Charge Stage = Float - The Float stage is a maintenance
charge mode that maintains a constant voltage – while delivering up to
the maximum rated current of the charger in order to power any DC loads
connected to the batteries. Most 3-stage chargers fi nish the Charge mode
in Float and remain in Float as long as an AC source is available on the
input of the charger. The fl oat voltage is determined by the battery type
selected in the 03B Battery Type menu item. Unlike Multi-Stage mode,
in Float mode there is no Full Charge mode.
Why should I use the Float mode? Float mode is typically used when the
charger is the only charge source connected to the batteries. This mode will
maintain the batteries at the fl oat voltage. If using fl ooded batteries and the
charger is in fl oat for an extended period, the water level should be checked
every two to three weeks for proper levels.
Set Final Charge Stage = Silent - Silent mode stops charging once it
transitions from Absorb mode to “Silent”. As the charger enters Silent
mode it monitors the battery voltage and starts charging once the
batteries fall to the DC Volts to Rebulk setting. Once the batteries reach
this setting, the charger restarts the charge cycle in Bulk mode and then
transitions to Absorb. After the Absorb cycle, the charger again transitions
to Silent mode and continues this cycle.
Set DC Volts to ReBulk - When Silent mode is selected, you must also
set the DC voltage set-point where the charger restarts the Bulk mode.
This setting should be the lowest DC volts to which you will allow the
batteries to fall before starting a new Bulk cycle. Typically, the lowest
DC volts the batteries are allowed to fall is 12.0 to 12.2VDC, (12-volt
systems) 24.0 to 24.4VDC (24-volt systems), and 48.0 to 48.8VDC (48volt systems) respectively.
Default setting - Set DC Volts to ReBulk = 12.0, 24.0, 48.0 VDC
Why should I use the Silent mode? Silent mode is typically used when
an alternate charge source is available and able to fully charge, or fi nish the
charge cycle after the Absorb stage. A major difference between Multi-Stage
mode and Silent is that Silent mode returns to Bulk mode instead of Float
mode. In Silent mode you can also adjust the Rebulk set-point in order to
allow the alternate charge source to provide more of the battery charging.
The AGS Setup and BMK Setup menus only display if the related accessory
is connected to the router’s inverter/charger, or is directly connected to the
router and has been assigned to one of the router’s communication ports.
The REM Setup menu only displays if the remote is connected and assigned

04 AGS Setup
This menu is used to set up the functions related to the ME-AGS-N (Automatic
Generator Start - Network version). These functions automatically start and
stop the generator based on the following conditions:
04A Gen Run VDC: Starts/stops based on battery voltage as shown on
•
the System Home screen.
04B Gen Run Time: Starts/stops based on time of day. This feature
•
uses the router clock to determine start and stop times.
04C Gen Run Amps: Starts/stops based on the AC amp load on the
•
inverter while in Invert mode. When the AGS is connected directly to the
router, the AGS starts/stops based on the total AC amp load of all the
inverters in the parallel system (while inverting). When the AGS is directly
connected to an inverter, the AGS starts/stops based on that inverter’s
AC amp load (while inverting). The AC amp load value is determined from
the 02C Load Amps menu item (METER button’s AC Meters menu).
04D Gen Run SOC: Starts/stops based on the SOC reading from the BMK.
•
The AGS uses the SOC value as shown on the System Home screen to
determine when start/stop. If multiple BMK’s are installed in the system,
the System Home screen will display the SOC value of the BMK that is
connected to the lowest numbered port.
Example: An inverter connected to Port 2 has a BMK connected to
its Network port; this BMK is designated as “P2ACC”. A second BMK is
connected directly to Port 3 on the router and is designated as “P3”. The
System Home screen will display the SOC value from the BMK designated
as P2ACC.
04E Gen Run Temp: Starts based on the interior temperature or the
•
A/C thermostat as determined by the AGS temperature sensor, and stops
after the Gen Run Time setting is completed.
Info: For detailed information on the ME-AGS-N and all its
menus, refer to it’s owner’s manual (PN: 64-0039).
The ME-BMK/ME-BMK-NS (Battery Monitor Kit) accurately measures the SOC
(State Of Charge), battery voltage, and the DC amps of the battery bank.

service personnel with troubleshooting, and also allows the factory default
settings for the inverter/charger and any connected accessory to be restored.
See Section 3.2.5 for more detailed information.
5.1.5 Rotary SELECT Knob
The rotary SELECT knob is similar to a dash radio knob and is used to easily
view and select various menu items and settings displayed on the LCD screen.
Turn the rotary knob clockwise/counterclockwise to view the different menu
items and the available inverter/charger, ME-AGS-N, and ME-BMK/ME-BMKNS settings. Press the rotary knob to select a menu item or to save a setting
once it is displayed on the LCD screen (hold down the SELECT knob for 10
seconds to refresh the LCD display).
Info: All adjustable inverter/charger settings in the router
(except for 01B Contrast, 01C Backlight, and 03 AGS Control
— which revert back to default) are saved in non-volatile memory
until changed — even if an inverter reset is performed or if all
power to the router or inverter is removed.
CAUTION: An accessory that is networked to the inverter
may have adjustable settings that revert back to default if all
power to the inverter is lost. Refer to the particular accessory’s
owner’s manual to determine if any setting for the accessory
is affected.
Turning the inverter on: Press the ON/OFF INVERTER button to activate the
inverter function. The inverter will either be actively “Inverting” by using power
from the batteries to power the AC loads (see Figure 5-4); or, the inverter will
be “Searching” for a load by using very little power from the batteries, if in
Search mode (see Figure 5-3). The green INV LED is on when the inverter is
actively inverting, and the green INV LED fl ashes while searching.
Turning the inverter off: While the inverter is actively inverting or searching,
press the ON/OFF INVERTER button to switch the inverter function off; which
turns the green INV LED off (see Figure 5-2).
Inverter Standby: The inverter is in standby when it is active (green INV
LED is on) but not actively providing power from the batteries to the inverter
loads. This can happen when an external AC power (utility/shore or generator)
is passing through to power the AC loads; or, in a parallel application where
the slave inverters are not actively powering a load, but ready and waiting
to power the load if needed.
5.2.2 Charger Mode
Turning the charger on: The Charge mode is automatically activated and
begins when acceptable AC power (utility or generator) is connected to the
input of the inverter. While in Charge mode, the display shows Charging, Bulk
Charging, Absorb Charging, Float Charging, Full Charge, Charger Standby,
Silent, Force Float, and Equalizing (see Figures 5-6 thru 5-14). (When the
charger is ON and actively charging, it produces DC voltage and current to
charge your batteries, and the CHG LED is solid.)
Charger Standby: When the charger is actively charging, press the ON/OFF
CHARGER button to switch the charger to Charger Standby. While in Charger
Standby, the incoming AC is still available on the inverter’s output, but the
charger is not allowed to charge. The LCD displays “Charger Standby” and
the CHG LED fl ashes (see Figure 5-11).
Info: To resume charging momentarily press the ON/OFF
CHARGER button, or disconnect/reconnect AC power to the
inverter’s input.
Equalize charging: Equalizing is a ‘controlled overcharge’ performed after
the batteries have been fully charged. It helps to mix the battery electrolyte
(to reverse the buildup of stratifi cation), and also helps to remove sulfates
that may have built up on the plates. These conditions if left unchecked will
reduce the overall capacity of the battery.
WARNING: Do not perform an Equalization charge without
reading and following all safety precautions pertaining to
charging/equalization as noted in this manual, and any
equalization information in the inverter’s manual.
To enable the Equalization charge, see Figure 5-14 and follow all related
information on page 60.
A status message may be an operational or fault message indicating the
inverter/charger’s current operating status. This section will cover the
inverter/charger’s operating and fault modes, and the available status
messages under each mode. Use these status messages and the Status
LED’s to determine the inverter/charger’s current operating status, and to
help troubleshoot the system if a fault occurs.
The System screen displays inverter/charger status messages on the top line
and any accessory status messages on the second line (see Figure 5-1.1). The
FAULT LED fl ashes to indicate that one of the ports has a fault. To determine
which port has the fault, press the PORT button or rotate the SELECT knob
until the FAULT LED turns solid. The fault now displays on the second line.
The fi rst line identifi es if it is an inverter/charger fault or an accessory fault
(see Figure 5-1.2).

then reconnected, the charger will go directly to the Float mode and will not
do a Bulk or Absorption charge cycle.
CAUTION: Using the Force Float mode may not fully charge the
batteries. Most batteries require a Bulk and Absorption charge
cycle in order to fully recombine the electrolyte in the batteries
and bring the specifi c gravity to the proper level. Be sure to check
with your battery manufacturer before using this setting.

Figure 5-14, Equalizing Mode
•
Equalizing - This display indicates that the battery charger is delivering
the equalize voltage to the batteries. See Table 3-1 to determine the equalize
voltage for your battery type.
Equalize charging can be enabled by the ON/OFF CHARGER button – if the
SETUP menu’s 03B Battery Type setting allows. Equalization charging can only
be enabled while the charger is in Float Charge or Full Charge mode. To turn
on Equalize charging, ensure the LCD display reads “Float Charging” or “Full Charge”, and then press and hold down the ON/OFF CHARGER button (about
5 seconds) until the LCD screen displays “Equalizing”.
The Equalize charge will continue for four hours and then automatically stop
and return to Float charging. The Equalize charge can be manually stopped by
pressing and holding down the ON/OFF CHARGER button (about fi ve seconds)
until the LCD screen displays “Float Charging”.
During Equalizing mode the batteries will begin gassing and bubbling vigorously
– which consumes water. Ensure each cell has adequate distilled water levels
prior to equalizing, and add water as needed after equalizing.
WARNING: Equalizing produces hydrogen and oxygen gas. To
avoid explosions, ensure the battery compartment has adequate
ventilation in order to dissipate this gas.
CAUTION: Ensure your batteries can be equalized. Only do so
if permitted by your battery manufacturer or dealer. Performing
an Equalize charge on batteries other than liquid lead acid or
certain AGM types could permanently damage them. Contact
your battery manufacturer for their recommendations.
CAUTION: Ensure the DC loads will not be damaged by the higher
voltage applied to the batteries during the Equalize charge. If in
doubt, disconnect the DC loads to prevent damage.
Info: Equalization charging is not available if GEL or AGM 2 is
selected as the SETUP menu’s 03B Battery Type setting.
How often should I equalize? Some experts recommend that heavily used
batteries should be equalized periodically, ranging anywhere from once a
month to once or twice per year. Other experts only recommend equalizing
when the cells have a low specifi c gravity, or when the difference between any
individual cell has a specifi c gravity reading greater than .015 after being fully
charged. Contact your battery manufacturer for their recommendations.
How long should I equalize? While the batteries are gassing, monitor the
specifi c gravity readings every hour. When the specifi c gravity readings no longer
increase, the Equalization charge is complete and should be stopped.

The charger is in Battery Saver mode. This mode
monitors battery voltage level and only charges
if the battery voltage decreases to a low level.
Silent mode will automatically start charging
when the ReBulk setting is reached.
The charger current is automatically decreased
because: 1. Charger Back-off - the inverter’s
internal temperature is getting hot, current is
decreased to reduce/maintain temperature; or,
2. Low AC Input Voltage - the input AC voltage
is <85 VAC, charger is disabled to help stabilize
incoming AC voltage to prevent AC disconnect.
The inverter is detecting AC voltage (from utility
or an AC generator) on the inverter’s AC input
terminals.
1. Inverter is disabled; or, 2. Router is in Power
Save mode - press any button to activate LED’s.
Inverter is enabled - 1. Supplying AC power on
the output; or, 2. In Standby (if both INV and
CHG LEDs are on); the inverter will automatically
supply AC power to the loads if utility or
generator power is lost.
Inverter is in Search mode (the AC load is below
the SETUP menu’s 02A Search Watts setting).

6.1 Troubleshooting Tips
6.1.1 Inverter Problems
•
Inverter turned on, green LED on inverter blinking, no output:
Inverter is in Search mode. Either defeat Search mode, if not needed, or turn
on loads greater than the Search Watts setting.
6.1.2 Charger Problems
•
Unit won’t transfer to Charge mode with AC applied: Is charge
(CHG) LED on router blinking? If not, then the charger does not recognize
the incoming as AC being within acceptable limits. Measure the input AC
voltage at the inverter input terminals, it should be 120VAC +/ 20 VAC
(230VAC +/- 40 VAC for export models). Also, check that the VAC Dropout
setting on the router is 80 VAC or less (export models: 160 VAC or less).
If the CHG LED is blinking, the transfer relay should be closing within 20
seconds, and the unit should begin charging. If the LED is on solid, the relay
should be closed, and the charger should begin charging.
•
Transfer relay closes, then opens and continues to cycle: AC
voltage is too low, or has transients that drop the AC voltage momentarily.
Change the VAC Dropout setting to 60 VAC (120VAC for export models) and
check for improvements. If the cycling continues, back off the Charge Rate
from 100% to 10%.
This cycling may also be caused if the AC output of the inverter is connected
to the inverter’s AC input, check for proper input and output AC wiring.
•
Charger not charging even though CHG LED is on steady and
the unit says “Charging”: Full charge rates are not obtained in Charging
mode, only after this mode changes to Bulk Charging, Absorb Charging, or
Float Charging modes.
•
Charger not charging even though CHG LED is on steady and the
unit says “Bulk Charging” (or “Absorb Charging”): Check the DC amps
meter and DC voltmeter on the router display. It should be 80% or more of
rated charge current if the battery voltage is under 14.0 VDC (28.0 VDC on
24-volt models or 48.0 VDC for 48-volt models). If not, check the 03C Max Charge Rate setting and verify the setting is 80% or greater. Still low charge
rate? Check the 03A AC Input Amps setting. If no AC loads are being passed
through the inverter, the 03A Input Amps setting must be 15 amps (25 amps
for 3kW unit) or greater to receive the full charge rate.
•
Charger says “Float Charging” not “Bulk Charging” when the AC
is fi rst plugged in: Check DC voltmeter on the router display. If the battery
is over 13.0 VDC (26.0 VDC for 24-volt models or 52.0 VDC for 48-volt
models) then the battery was already charged and the charger automatically
goes to Float Charging to keep from overcharging the batteries. Try the
Restart Bulk setting from the 02 CHG Control menu.
•
Charge amps are lower than expected, or is 0 amps DC: Measure
input AC voltage and increase if the input voltage is under 90 VAC. The
charge rate is reduced to keep the input voltage above 90 VAC. Also, check
the 03A Input Amps and the 03B Max Charge Rate settings to determine if
the current is being limited.
•
Charger output voltage is different than expected: Check the
Battery Temperature Sensor (BTS) temperature. If the BTS is installed, the
charge voltage settings will increase if the temperature around the BTS is
below 77° F (25° C) and decrease if the temperature around the BTS is
higher than 77° F (25° C).
Press and hold the Power ON/OFF button (see Figure 6-1) for approximately
fi fteen (15) seconds until the Charging/Inverting Status LED comes on and
fl ashes rapidly. Once the rapid fl ashing has begun, release the Power ON/
OFF button. The Status LED will go off after the button is released.
After the inverter reset is completed, press the Power ON/OFF button to turn
the inverter ON.
Some older inverter models do not allow an inverter reset. If the inverter reset
fails you will need to power-down the inverter using the procedure below. In
either case, if an internal fault does not clear the inverter will require repair
at an authorized service facility.
Info: The Power ON/OFF button is a small momentary type
switch which operates by lightly pressing and releasing.
Info: All adjustable inverter/charger settings in the router
(except Setup 01B Contrast, 01C Backlight, and 03 Gen Control
- which revert back to default) are saved in non-volatile memory
and are preserved until changed - even if an inverter reset is
performed or if all power to the router or inverter is removed.
1. Press and hold th e Power
ON/ OFF pushbut ton for 15
seconds .
2. Watch the Charging/
Inverting Status LED, after
approximately 15 seconds it
should come on an d flash
rapidly to indicate the inverter
has reset. The Statu s LED will
go off after the pushbu tton is
released.
Figure 6-1, Performing an Inverter Reset
6.3 Powering Down the Inverter
To power-down the inverter:
Remove all AC power (utility or generator power) to the inverter.
1.
Open all the inverter DC disconnects (or disconnect the positive bat-
2.
tery cable to the inverter).
Ensure all inverters and the router are disconnected from all AC and
3.
DC power (the router display will be blank).
After the inverters have been disconnected from all power for 30
4.
seconds, reconnect the inverter DC disconnects (or reconnect the
positive battery cable) and resume operation.
Info: If DC disconnects are not used, there may be a momen-
tary spark when the positive battery cable is connected to the
inverter’s terminal. This is normal and indicates that the inverter’s
internal capacitors are being charged.
