 FLEXmax

The FLEXmax 80 (AKA FM80) is the latest innovation in Maximum Power Point Tracking (MPPT) charge controllers from OutBack Power Systems. The FLEXmax 80's innovative MPPT algorithm is both continuous and active, increasing your renewable energy yield up to 30%. Thanks to 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 80 charge controller 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 80 to be remotely programmed via the optional MATE system display and controller.

The FLEXmax 80 has a broad DC input range of up to 150VDC and an 80 amp DC current rating. FLEXmax 80 is compatible with 12 VDC to 60 VDC systems, allowing for flexibility in both wiring as well as solar array sizing. The ability to step-down a high voltage solar array to a low voltage battery helps save money by reducing the size of wire required, thereby making the installation easier. Revised menus and setup procedures provide a superior installation and user experience.

The new FLEXmax 80 is a great choice when you demand a high performance, efficient and customizable charge controller for your advanced power system.
