OutBack Flexmax 80
FM80-150 MPPT 80A

OutBack Out Back Flexmax 80 FM80-150 MPPT Charge Controller 80A is the latest innovation in Maximum Power Point Tracking (MPPT) charge controller from OutBack Power Systems.

The FLEXmax's innovative MPPT algorithm is both continuous and active, increasing your renewable energy yield up to 30%. Thanks to enhanced cooling, the Flexmax controller can operate at its full 80 amp maximum current rating in ambient temperatures as high as 104°F (40°C).

Included are all of the features first developed by OutBack Power in the revolutionary MX60, such as support for a wide range of nominal battery voltages and the ability to step-down a high voltage solar array to recharge a low voltage battery. A built-in backlit display shows status information at the touch of a button. Enhanced network communications allow the FLEXmax to be remotely programmed via the optional MATE system display and controller.
