batteries for further information.
INTRODUCTION
MX60 PV MPPT (Maximum Power Point Tracking) Charge Controller
The OutBack MX60 PV MPPT Charge Controller o ers an e cient, safe, multi-stage recharging
process that prolongs battery life and assures peak performance from a solar array. This component
allows customized battery recharging. The MX60 features include:
• 60 amps maximum continuous output current
• Engineered to work with 12, 24, 36, 48, and 60 VDC battery voltages
• Backlit LCD display screen with 80 characters (4 lines, 20 characters per line)
• Last 64 days of operational data are logged for review
• Voltage step-down capability allowing a higher PV array voltage con guration
• Manual and auto-equalize cycles
The following are the maximum recommended wattage for the most common solar arrays under
Standard Test Conditions (1000 watts per square meter of solar panel at 25° C or 77° F):
• 12 VDC battery systems—up to 800 watts of solar panels
• 24 VDC battery systems—up to 1600 watts of solar panels
• 48 VDC battery systems—up to 3200 watts of solar panels
The MX60 also features Maximum Power Point Tracking (MPPT), which seeks out the maximum
power available from a solar array and uses it to recharge the batteries. Without this feature, the
solar array does not operate at the ideal operating voltage and can only recharge at the level of the
battery voltage itself. The MX60 “sweeps” the array’s operating voltage at user-determined sweep
intervals to track the Maximum Power Point (MPP) of the PV array.
This manual covers the wiring, installation, and use of the MX60, including explanations of all the
Menus displayed on the LCD screen. The MX60 is designed to seamlessly integrate with other
OutBack components and can be remotely monitored (up to 1000 feet) by the optional OutBack
Power Systems MATE display.

INSTALLATION GUIDELINES AND IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This product is intended to be installed as part of a permanently grounded electrical system
as shown in the system con guration sections of this manual with the following important
restrictions:
• The negative battery conductor should be bonded to the grounding system at only one point in the
system. If a GFP (Ground Fault Protector) is present, the battery negative and ground are not bonded.
• With the exception of certain telcom applications, the MX60 should never be positive grounded (see
page 61, Applications Notes).
• The equipment ground on the MX60 is marked with this symbol:
• If damaged or malfunctioning, the MX60 should only be disassembled and repaired by a
quali ed service center. Please contact your renewable energy dealer/installer for assistance.
Incorrect reassembly risks malfunction, electric shock or re.
• The MX60 is designed for indoor installation or installation inside a weatherproof enclosure. It must not be
exposed to rain and should be installed away from direct sunlight.
• For routine, user-approved maintenance:
Disconnect all circuit breakers and related electrical connections before doing any cleaning
or adjustments.
Solar modules may produce hazardous voltages when exposed to light; unless
servicing them at night, cover the modules with opaque material before servicing any
connected equipment.
Standards and Requirements
All installations must comply with national (NEC) and/or local electrical codes; professional installation
is recommended.
DC and Battery-Related Installation Requirements:
• All DC cables must meet NEC standards or applicable local code standards.
• Shut o all DC breakers before connecting any wiring.
• Torque the four-position terminal block and ground terminals to 30 inch pounds/4Nm.
• All wiring must be rated at 75° C or higher.
• Use up to 2 AWG (6.54 mm) to reduce losses and ensure high performance of MX60 (smaller cables
can reduce performance and possibly damage the unit).
• Keep cables together (e.g., using a tie-wrap) as much as possible.
• Ensure both cables pass through the same knockout and conduit ttings to allow the inductive cur-
rents to cancel.
• DC battery over-current protection must be provided as part of the installation. OutBack o ers both
breakers and fuses for over-current protection.

WARNING - WORKING IN THE VICINITY OF A LEAD ACID BATTERY
IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES DURING
NORMAL OPERATION.
Design the battery enclosure to prevent accumulation and concentration of hydrogen gas
in “pockets” at the top of the enclosure. Vent the battery compartment from the highest
point to the outside. A sloped lid can also be used to direct the ow of hydrogen to the vent
opening.
CAUTION - To reduce risk of injury, charge only deep-cycle lead acid, lead antimony, lead
calcium, gel cell or absorbed glass mat type rechargeable batteries. Other types of batteries
may burst, causing personal injury and damage. Never charge a frozen battery.
PERSONAL PRECAUTIONS
• Someone should be within range of your voice to come to your aid if needed.
• Keep plenty of fresh water and soap nearby in case battery acid contacts skin, clothing,
or eyes.
• Wear complete eye protection. Avoid touching eyes while working near batteries. Wash
your hands with soap and warm water when done.
• If battery acid contacts skin or clothing, wash immediately with soap and water. If acid
enters an eye, ood the eye with running cool water at once for at least 15 minutes and
get medical attention immediately following.
• Baking soda neutralizes lead acid battery electrolyte. Keep a supply on hand in the area of
the batteries.
•
NEVER smoke or allow a spark or ame in vicinity of a battery or generator.
• Be extra cautious to reduce the risk of dropping a metal tool onto batteries. It could shortcircuit the batteries or other electrical parts that can result in re or explosion.
• Remove personal metal items such as rings, bracelets, necklaces, and watches when
working with a battery or other electrical current. A battery can produce a short circuit
current high enough to weld a ring or the like to metal, causing severe burns.
8
OPEN CIRCUIT VOLTAGE/WIRE AND DISCONNECT SIZING
Maximum Open Circuit Voltage (Voc)
• Voc is the unloaded voltage generated by the solar array.
141 VDC MX60 suspends operation to protect components
150 VDC max open circuit voltage with the coldest environment (although the MX60 shuts
down at 141 VDC, it can absorb up to 150 VDC from the array; anything higher than 150 VDC
will damage the MX60)
• As every brand of panel is di erent, be sure to know the manufacturer’s speci cations.
• Local temperatures vary seasonally and will a ect panel voltage.
Hot weather: lower open circuit voltage/lower maximum power point voltage
Cold weather: higher open circuit voltage/higher power point voltage
Allow for ambient temperature correction using the following table:
25° to 10° C (77° to 50° F) multiply by 1.06
9° to 0° C (49° to 32° F) multiply by 1.10
-1° to -10° C (31° to 14° F) multiply by 1.13
-11° to -20° C (13° to -4° F) multiply by 1.17
-21° to -40° C (-5° to -40° F) multiply by 1.25
Check the PV array voltage before connecting it to the MX60.
Wire and Disconnect Sizing
• The output current limit of the MX60 is 60 amps.
• Use a minimum of 6 AWG (4.11 mm) wire for the output between the MX60 and the battery bus
bar conductors; a larger size might be required due to temperature and/or conduit ll corrections.
• Install OutBack OBB-60 or OBB-80 amp breakers for disconnect and over current protection.
• The largest PV array that can connect to an MX60 should have a rated short-circuit current of 48
amps STC (Standard Test Conditions).
• Input conductors and circuit breakers must be rated at 1.56 times the short-circuit current of the PV
array. OutBack OBB 100% duty continuous breakers only need to be rated at 1.25 times the short-
circuit current.
• Please see the wire Distance Chart and complete Wire and Disconnect Sizing on pages 81-83 for
other suitable conductor/wire sizing.

NOTE: Each MX 60 requires its own PV array. DO NOT PARALLEL MX 60 PV+ AND PV- TERMINALS TO
THE INPUT OF THE MX60. This can cause problems with the MPPT and can cause an MX60 failure.
NOTES
• An optional battery Remote Temperature Sensor (RTS) is recommended for accurate
battery recharging (only one RTS is needed for multiple OutBack Series Inverter/Chargers
and MX60 units when an OutBack HUB and a MATE are parts of the system). When one RTS
is used, it must be connected to the component plugged into the Port 1 of the HUB.
• AUX modes include powering a relay, LED indicator, and Piezo-buzzer or brushless fan.
• The OutBack MATE can display a single MX60 or multiple MX60s if connected to a HUB.
• Surge protection on the input (PV) side of the MX60 and on the battery side is required for
• Always install the MX60 in an upright position. The MX60 must be secured for a safe
installation and to retain warranty protection. Use a 1 5/8” wood screw through the slotted
hole at the top of the MX60 and at least two screws in the internally located holes at the
bottom of the MX60’s enclosure.

manufacturer’s recommendations). If an RTS is not in use,
please see the Non-Battery Temperature Compensated
System values (page 86) and adjust the ABSORB/FLOAT
values accordingly.
21
AUX MODE
The AUX is a secondary control circuit—essentially, a small power supply that provides a 12 VDC (up to
200 milliamps) output current. It is either active (12 VDC on) or inactive (12 VDC o ).
• To access the AUX MODE from the MAIN Menu, press the < >soft key until the asterisk is in front of
the AUX selection.
• A 200 milliamps or less, 12 VDC device can be wired directly to the AUX terminal; higher output DC
loads require a 12 VDC coil relay—also rated up to 200 milliamps or less for the DC coil—which itself
is connected to the AUX output. An internal, re-settable Positive Temperature Coe cient (PTC) fuse
protects the AUX internal components.
• For certain AUX control applications the use of a solid state relay is preferred. This is particularly
bene cial with applications such as the Diversion mode where fast switching (often called PWM
control) allows a more constant battery voltage to be maintained. Both DC and AC load switching
solid state relays are widely available from many sources. Eurotherm and Power-IO are two suggest-
ed solid state relay manufacturers.
• Most AUX modes or functions are designed for specialized applications and are infrequently used.
• Only one AUX MODE can operate at a time (even if other modes have been preset).
• Press the <EXIT> soft key to initiate the chosen AUX MODE.
• See Figure 5, page 30, for an AUX set-up wiring diagram.
In this Menu, ON and

When an AUX MODE is ON, 12 VDC is available at the AUX terminals and a condition, such as a voltage
set point, is met. Other modes can be programmed in lieu of the speci c ones listed here, but the Vent
Fan mode is most easily changed (e.g., to activate an alarm instead of a fan). Here are the default AUX
modes:
• Manual—pressing either the < ON> or <OFF> soft key manually activates or deactivates AUX.
• Vent Fan— when the Vent Fan voltage set point is exceeded, the vent fan will run for at least 15
seconds (the fan helps remove hydrogen from battery enclosure), even if the set point is exceeded
for only a few seconds due to a surge. If the set point is exceeded for longer than 15 seconds, the fan
will stay on until the voltage drops below the set point. It then takes 15 seconds before the fan shuts
o . This is an external fan and not to be confused with the MX60’s internal, thermally activated fan
which cools the unit.
• PV Trigger—activates an alarm or relay (that disconnects the array); when the PV input is too high
and exceeds the user-determined voltage set point (should not go over 150 VDC), the PV Trigger
disconnects after a minimal adjustable amount of Hold Time.
• Float—powers a load if the MX60 is producing power in the Float stage.
• Error Alarm—useful for monitoring remote sites, switches to the O state if the MX60 has not
charged the batteries for 26 hours or more (not an audible alarm, only displayed as a printed
message on MX60 AUX Menu).
• Diversion—diverts excess power away from batteries when a wind or hydro generator is connected
directly to the batteries.
• Low Batt Disconnect—activates/deactivates the AUX load(s) when a user-determined voltage and
time levels are reached.
24
• Remote—allows OutBack MATE to control the operation of the AUX MODE (see MATE manual for
details).

Each recharging state—Absorb, Float, or EQ—has a recharging voltage set point. The Diversion AUX
MODE can be active (On) when the battery voltage is raised above one of these set points for a
certain amount of time or inactive (O ) when it falls below. The user can determine these voltages
and times. In the example above, when the RE source (wind or hydro) raises the battery voltage
00.2v above the chosen set point for a Delay time of 10 seconds—the AUX Output will be active.
When the battery voltage falls 00.3V below the HYST voltage set point for a Hold time of 15 sec
– the AUX Output will be inactive (O ). See Figure 5 for Diversion Load and AUX Wiring Set-Up.

EQ—BATTERY EQUALIZE
The intent of an equalization charge is to bring all battery cells to an equal voltage. Sealed batteries
should not be equalized unless speci cally instructed by the manufacturer. Shut o or minimize all AC
and/or DC loads when equalizing and be sure the EQ voltage will not damage any DC load. If possible,
ensure the EQ cycle starts and stops the same day it is initiated or unnecessary battery gassing can
occur.
• Occasional equalization extends the life of ooded electrolyte batteries.
• Proceed with caution! A vent fan is recommended in enclosed spaces.
• The MX60 allows the user to set voltages and times of equalization process.
• Both manual and auto modes are available.
• EQ is not battery temperature compensated.
• Always check the electrolyte level in the batteries before and after equalizing.

WIDE/LMIT Battery Temperature Compensated Limits
During cold weather, a battery often requires a higher recharging voltage. Lower quality inverters
might not accommodate these higher voltages and can shut down during recharging, cutting o
power to their loads. The MX60 allows the user to lower the compensated voltage in the Absorb cycle
so these inverters will remain operating. Also, some batteries have an absolute voltage limit that
should not be exceeded and the WIDE/LMIT option allows the user to control this during recharging.
WIDE allows the RTS full control over recharging; LMIT sets the ceiling and oor voltages for the RTS.
During hot weather, the LMIT feature set point assures recharging will continue at a high enough
voltage rather than dropping too low in reaction to a higher ambient temperature. This assures
the recharging voltage adequately charges, but should be monitored according to the battery
manufacturer’s recommendations.
The RTS default compensated voltages apply if the WIDE/LMIT option is set to WIDE in the MISC menu.
The upper and lower LMIT settings can be viewed in the second menu of the Log2 screen when LMIT is

The MX60’s sunrise-related activity can be in uenced. During certain days of the year, the sun never
“sets” in parts of Alaska, for instance, and the PV output is constant. The MX60 responds to these
situations by generating its own sunrise reading at either 24 or 25 hours with 25 hours being the
never Restarts. Mode 0 would be chosen to avoid
spinning a microhydro generator every 1.5 hours.

MICRO-HYDRO, WIND TURBINE, AND FUEL CELL APPLICATIONS
The MX60 is designed to work with solar arrays. Although it will work with micro-hydro and fuel cell,
OutBack Power Systems can only o er limited technical support for these applications because there is
too much variance in micro-hydro and fuel cell generator speci cations. When used for micro-hydro or
fuel cell applications, the MX60 warranty will be honored only if the manufacturer and turbine model
have been approved by OutBack Power Systems. Please check with one of the following manufactur-
ers or OutBack Power Systems before employing the MX60:

The MX60 is not compatible with wind turbine applications and OutBack cannot warranty its use in
these applications.
MICRO-HYDRO AND FUEL CELL SYSTEMS PERFORMANCE OPTIMIZATION
Micro-hydro and fuel cell systems are di erent than PV systems, whose Voc output is more subject to
change due to weather and time of day. A PV system normally nds its Maximum Power Point voltage
between 50-90% of its Voc. The default value for the MX60 is 77% of a solar array’s Voc and is displayed
on the Park Mpp screen. A microhydro or fuel cell system’s MPP voltage can be outside of this range.
The MX60 allows a user to experiment and nd more appropriate set points to best capture the MPP
voltage. If the output current is under ve amps, Auto Sweep will park the voltage using whatever
percentage value is displayed in the Park Mpp screen. Otherwise, Auto Sweep begins sweeping the Voc
output and works its way down until the optimum percentage of input voltage yields the MPP voltage.
If U-Pick % Voc is chosen, the MPP is calculated by whatever value is found in Park Mpp, even if it’s not
the optimal value for determining the MPP voltage. For this reason, OutBack normally suggests leaving
the system in Auto Sweep mode and the 77% default percentage value, but recommends experiment-
ing with changing this value when a micro-hydro or fuel cell system is in use.
54
To adjust these values and enhance the performance of these systems, use the MX60 ADVANCED
MENU to make changes. To determine your micro-hydro or fuel cell system’s best settings for MPP
voltage, do the following:
1. Use Auto Sweep and record the watts yielded. This value should be in line with your generator
capacity.
2. Switch to U-Pick % Voc mode and input di erent Park Mpp percentage values, checking the watts
value for each. This will require some experimentation.
• The MX60 can operate at any of the following xed percentages, selected in the Park Mpp
screen in the ADVANCED Menu selection:
40%, 50%, 67%, 70%, 72%, 75%, 76%, 77%, 78%, 80%, 81%, 83% or 85% of the measured
open circuit voltage
• The user will have to experiment with each of the 13 xed percentage values to
determine an appropriate xed percentage value. Typical xed values between 67% up to
78% have provided optimal results; however, each system is di erent and these xed
percentage values should be used as guidelines only
3. Compare the Auto Sweep and U-Pick % Voc values and determine which will best t
your system.
In addition to establishing the best mode and percentage values for determining the MPP voltage, a
user can also adjust the sweep interval and the range of values the MX60 uses to search for the MPP
voltage.
(If necessary, re-enter the system password 141 at any point while optimizing the system’s
performance.)
55
ADVANCED MENU (Micro-Hydro)
Mpp Range Limit % (Auto Sweep Mode only)
The MX60 searches for the MPP voltage by sweeping the input voltage up to one half (default) of
the Voc, which is based on values appropriate for a solar array. Micro-hydro and fuel cell systems can
require a broader range, normally on the lower end. Adjusting the lower limit, expressed as 1/2 on
the display screen, for FULL allows the MX60 to sweep the input voltage close to the battery voltage
instead of 1/2 (or 50%) of the Voc.
This adjustment only a ects the initial sweep at the beginning of the day and any subsequent sweeps caused
by Auto-Restart or any forced restart of the MX60.
In addition to adjusting the Mpp Range Limit, changing the Sweep Interval from its default three-
minute setting to zero minutes will also enhance the performance and reliability of some applications’
voltage input system.
