SCOPE
This manual provides safety guidelines and installation information for the FLEXmax 60 and FLEXmax
80 Charge Controller
Maximum Power Point Tracking Charge Controllers. It does not provide information
about speci c brands of solar panels and supplies limited information on batteries. Contact the
supplier or manufacturer of the solar panels or batteries for further information.
INTRODUCTION
The FLEXmax 60 and FLEXmax 80 Maximum Power Point Tracking Charge Controllers *
The OutBack
Maximum Power Point Tracking Charge Controllers o er an e cient, safe, multi-stage
recharging process that prolongs battery life and assures peak performance from a solar array. Each
Charge Controller allows customized battery recharging. The Charge Controller features include:
• 80 amps maximum continuous output current up to 40° C without thermal derating for the
FLEXmax 80 and 60 amps for the FLEXmax 60
• Engineered to work with 12, 24, 36, 48, and 60VDC battery voltages
• Backlit LCD display screen with 80 characters (4 lines, 20 characters per line)
• Last 128 days of operational data are logged for review
• Voltage step-down capability allowing a higher PV array voltage con guration
• Manual and auto-equalize cycle
The following are the maximum recommended wattage for the most common solar arrays under
Standard Test Conditions (1000 watts per square meter to solar panel at 25° C or 77° F):
• 12VDC battery systems—up to 1250 watts (FLEXmax 80) or 800 watts (FLEXmax 60) of solar panels
• 24VDC battery systems—up to 2500 watts (FLEXmax 80) or 1600 watts (FLEXmax 60) of solar panels
• 36VDC battery systems—up to 3750 watts (FLEXmax 80) or 1200 watts (FLEXmax 60) of solar panels
• 48VDC battery systems—up to 5000 watts (FLEXmax 80) or 3200 watts (FLEXmax 60) of solar panels
• 60VDC battery systems—up to 6250 watts (FLEXmax 60) or 4000 watts (FLEXmax 60) of solar panels
Each Charge Controller also features Continuous 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. Each Charge Controller continuously tracks the array’s maximum
operating power.
This manual covers the wiring, installation, and use of the Charge Controllers, including explanations of
all the menus displayed on the LCD screen. Each Charge Controller is designed to seamlessly integrate
with other OutBack components and can be remotely monitored and con gured (up to 1000 feet) by
the optional OutBack Power Systems MATE display (version 4.0.4 or greater).
