FLEXmax 60 & 80 are the latest innovations in Maximum Power Point Tracking (MPPT) charge controllers from OutBack Power Systems. Their innovative MPPT algorithm is both continuous and active, increasing your renewable energy yield up to 30%With enhanced cooling, the FLEXmax 80 can operate at its full 80 amp maximum current rating in ambient temperatures as high as 104°F (40°C).

Included in the FLEXmax controllers 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 (12,24,36,48 & 60 VDC) and the ability to step-down a high voltage solar array (max. 150 VDC open circuit) to recharge a low voltage battery. A built-in backlit display shows status information at the touch of a button.
