The TriStar is suitable for a wide range of solar applications including homes,
telecom and industrial power needs.
TriStar controllers are configured for negative ground systems. There are no
parts in the controller’s negative leg. The enclosure can be grounded using
the ground terminal in the wiring compartment.
The TriStar is protected from faults electronically with automatic recovery.
There are no fuses or mechanical parts inside the TriStar to reset or change.
Solar overloads up to 130% of rated current will be tapered down instead of
disconnecting the solar. Over-temperature conditions will also taper the solar
input to lower levels to avoid a disconnect.
The NEC requires overcurrent protection externally in the system
(see
Section 2.3 step 6)
. There are no system disconnects inside the TriStar
enclosure.
Any number of TriStars can be connected in parallel to increase solar
charging current. TriStars can be paralleled ONLY in the battery charging
mode. DO NOT parallel TriStars in the load mode, as this can damage the
controller or load.
The TriStar enclosure is rated for indoor use. The controller is protected
by conformal coated circuit boards, stainless steel hardware, anodized
aluminum, and a powder coated enclosure, but it is not rated for corrosive
environments or water entry.
The construction of the TriStar is 100% solid state.
Battery charging is by a series PWM constant current charging, with bulk
charging, PWM absorption, float and equalization stages.
The TriStar will accurately measure time over long intervals to manage events
such as automatic equalizations or battery service notification.
Day and night conditions are detected by the TriStar, and no blocking diodes
are used in the power path.
LEDs, a push-button, and optional digital meters provide both status
information and various manual operations.
The date of manufacture can be found on the two bar code labels. One label
is on the back of the TriStar, and the other is in the wiring compartment. The
year and week of manufacture are the first four digits of the serial number. For
example:

1.6 Optional Accessories
Remote Temperature Sensor (RTS)
If the temperature of the system battery varies more than 5˚C (9˚F) during the year,
temperature compensated charging should be considered. Because the battery’s
chemical reactions change with temperature, it can be important to adjust charging to
account for the temperature effects. The RTS will measure the battery temperature,
and the TriStar uses this input to adjust the charging as required.
The battery charging will be corrected for temperature as follows:
• 12 V battery – 0.030 Volts per ˚C (–0.017V per ˚F)
• 24 V battery – 0.060 Volts per ˚C (–0.033V per ˚F)
• 48 V battery – 0.120 Volts per ˚C (–0.067V per ˚F)
The RTS should be used only for battery charging and diversion control. Do not use
the RTS for load control. The charging parameters that are adjusted for temperature
include:
• PWM regulation
• Equalization
• Float
• High Voltage Disconnect
See Installation, Step 4, for connecting the RTS to the TriStar.
Digital Meter Displays
Two digital meters can be added to the TriStar at any time during or after installation.
One version is mounted on the controller (TS-M), the other is suitable for remote
locations (TS-RM). The manual for installation and operation of the meter displays is
included with the meter.
The display is a 2x16 LCD meter with backlighting. Four push-buttons are used to
scroll through the displays and to execute manual functions.
There are a series of display screens that provide information such as:
• operating information and data
• operating bar charts (voltage and current)
• alarms and faults
• diagnostics
• settings
In addition, there are various manual functions built into the meter. For example, the
meter can be used to reset Ah data or start/stop equalizations.
One of 5 languages can be selected for the meter.
Ethernet Communications Adapter (EMC-1)
This product is an Ethernet gateway that provides web monitoring services,
a Modbus TCP/IP server, and a local web page server. End users can
collect information about their off-grid PV system remotely. One EMC-1
supports all products with MeterBus ports by bridging MODBUS TCP/IP
requests to serve LiveView pages for each product.

2.0 TriStar Installation
The installation instructions describe solar battery charging. Specific
instructions for the load control and diversion modes are provided as notes.
2.1 General Information
The mounting location is important to the performance and operating life of
the controller. The environment must be dry and protected as noted below.
The controller may be installed in a ventilated enclosure with sealed batteries,
but never in a sealed battery enclosure or with vented batteries.
If the solar array exceeds the current rating of the controller, multiple TriStars
can be installed in parallel. Additional parallel controllers can also be added in
the future. The load controllers cannot be used in parallel. To parallel diversion
controllers, refer to Morningstar’s website.
If solar charging and load control are both required, two separate controllers
must be used.
Stranded wires to be connected to the terminals should be prepared
rst with e.g. clamped copper heads, etc. to avoid the possibility of one
conductor free out of the connection screw, and possible contact with the
metal enclosure.
WARNING: Solar and battery fuses or DC breakers
are required in the system. These protection devices are external to the
controller, and must be a maximum of 70 amps for the TriStar-PWM-45, and 90
amps for the TriStar-PWM-60.
AVERTISSEMENT: Solaire et batterie fusibles ou
disjoncteurs DC sont nécessaires dans le système. Ces dispositifs
de protection sont externes au contrôleur, et doivent être un maximum de 70
ampères pour le TriStar-PWM-45, et 90 ampères pour le TriStar-PWM-60.
WARNING: Installation must comply with all US National
Electrical Code and Canadian Electrical Code requirements. Breakers
and fuses may require lower ratings than referenced above, so as not to exceed
any specic wire ampacity.
AVERTISSEMENT: Installation doit être conforme à
toutes les requirments US National Electrical Code et Code Canadien
d'Electricité. Disjoncteurs et fusibles peuvent exiger des cotes inférieures que
mentionnés ci-dessus de manière à ne pas pour dépasser n'importe quel fils
particulier admissible.
Maximum battery short-circuit current rating must be less than the interrupt
current rating of the battery over-current protection device referenced above.
2.2 Installation Overview

2.3 Installation Steps
The TriStar controller must be installed properly and in accordance with the
local and national electrical codes. It is also important that the installation be
done safely, correctly and completely to realize all the benefits that the TriStar
can provide for your solar system.
Refer to Sections 4.0 and 9.0 for information about the TriStar’s standard
battery charging programs and general charging needs for different
battery types. Refer to Section 5.0 for load control information, and
Section 6.0 for diversion.
Recommended tools:
• wire cutter • phillips screwdrivers • wire stripper
• torque wrench (to 50 in-lb) • slotted screw drivers • flashlight
Before starting the installation, review these safety notes:
• Do not exceed a battery voltage of 48V nominal (24 cells). Do not use a
battery less than 12V (6 cells).
• Do not connect a solar input greater than a nominal 48V array for battery
charging. Never exceed a Voc (open-circuit voltage) of 125V.
• Charge only 12, 24, or 48 volt lead-acid batteries when using the standard
battery charging programs in the TriStar.
• Verify the nominal charging voltage is the same as the nominal battery
voltage.
• Do not install a TriStar in a sealed compartment with batteries.
• Never open the TriStar access cover unless both the solar and battery
power has been disconnected.
• Never allow the solar array to be connected to the TriStar with the battery
disconnected. This can be a dangerous condition with high open-circuit solar
voltages present at the terminals.
Follow the installation steps in order: #1 through #8
Step 1 - Remove the Cover
Remove the 4 screws in the front cover. Lift the cover until the top edge clears
the heat sink, and set it aside. If an LCD meter display is attached
to the cover, disconnect the RJ-11 connector at the meter for access.
CAUTION: Do not remove the cover if power is present at any of the
terminals. Verify that all power sources to the controller are disconnected.
PRUDENCE : N’enlevez pas le couvercle en cas de tension à une des
bornes. Vérifiez que toutes les sources d’alimentation au contrôleur sont
déconnectées.
Step 2 - Mounting
Locate the TriStar on a wall protected from direct sun, high temperatures, and
water. Do not install in a confined area where battery gasses can accumulate.
NOTE: When mounting the TriStar, make sure the air flow around the
controller and heat sink is not obstructed. There should be open space above
and below the heat sink, and at least 75 mm (3 inches) clearance around the
heat sink to allow free air flow for cooling.
REMARQUE : Lors du montage du TriStar, assurez-vous que l’écoulement
d’air autour du contrôleur et du puits de chaleur n’est pas obstrué. Un espace
doit se trouver au-dessus et en dessous du puits de chaleur et un
dégagement de 75 mm (3 po) doit exister autour du puits de chaleur pour
permettre l’écoulement de l’air à des fins de refroidissement.
Before starting the installation, place the TriStar on the wall where it will be
mounted and determine where the wires will enter the controller (bottom, side,
back). Remove the appropriate knockouts before mounting the controller. The
knockouts are sized for 1 inch and 1.25 inch conduit.

Figure 2.3 - Step 2 Mounting Dimensions
Step 2 - Mounting (continued)
Refer to Figure 2.3.
Use the template provided in the shipping carton for
locating the mounting holes and for stripping the wires. Use two of the #10
screws provided for the two keyhole slots. Leave the screw heads protruding
enough to lock inside the keyhole slots (about 3.8 mm / 0.150 inch). Mount the
controller and pull it down to lock the screws into the slots. Use the remaining
two screws to fasten the controller to the wall.
Provide for strain relief for the bottom knockouts if conduit will not be used.
Avoid excessive pulling forces on the terminals from the wires.
Step 3 - Adjust the DIP Switches
An 8-position DIP switch is used to set-up the controller for its intended use.
All major functions can be set with the DIP switches.
See Section 7.0 for
additional custom settings using PC software.
NOTE: The instructions below are for solar battery charging.
Refer to Appendix 1 for Load Control DIP switch settings, and Appendix 2 for
Diversion Charge Control DIP switch settings.
REMARQUE : Les instructions ci-dessous concernent la charge de batteries
solaires. Reportez-vous à l’Annexe 1 pour les réglages du commutateur DIP
de contrôle de charge et à l’Annexe 2 pour les réglages du commutateur DIP
de contrôle de charge de diversion.
The DIP switches are located behind the negative power terminals. Each
switch is numbered. The solar battery charging functions that can be adjusted
with the DIP switches follow:

Figure 2.4 - Step 3 DIP Switch Functions
As shown in the diagram, all the positions are in the “OFF” position except
switch numbers 7 and 8, which are in the “ON” position.
NOTE: The DIP switches should be changed only when there is no power
to the controller. Turn off disconnect switches and remove all power to the
controller before changing a DIP switch. A fault will be indicated if a switch
is changed while the controller is powered.
REMARQUE : Les commutateurs DIP ne doivent être remplacés que si le
contrôleur est hors tension. Mettez tous les interrupteurs sur arrêt et mettez le
contrôleur hors tension avant de changer un commutateur DIP. Une panne
sera indiquée en cas de changement d’un commutateur alors que le
contrôleur est sous tension.
CAUTION: The TriStar is shipped with all the switches in the “OFF” position.
Each switch position must be confirmed during installation. A wrong setting
could cause damage to the battery or other system components.
PRUDENCE : Le TriStar est expédié avec tous les interrupteurs en position
« ARRÊT ». La position de chaque interrupteur doit être confirmée pendant
l’installation. Un mauvais réglage peut endommager la batterie ou d’autres
composants du système.

The auto voltage selection occurs when the battery is connected and the
TriStar starts-up. There should be no loads on the battery that might cause
a discharged battery to indicate a lower system voltage.
The DIP switch selectable voltages are for 12V, 24V or 48V lead-acid
batteries. Although the “auto voltage” selection is very dependable, it is
recommended to use the DIP switches to secure the correct system voltage.
