OUTBACK POWER-FLEXmax 100 300V MPPT Charge Controller

OutBack Power FM100-300VDC-AFCI FLEXmax 100Amp MPPT Solar Charge Controller


OutBack Power FM100-300VDC-AFCI FLEXmax 100A MPPT Solar Charge Controller


The FLEXmax 100 is the latest innovation in Maximum Power Point Tracking (MPPT) charge controllers form OutBack Power.

The advanced FM100 MPPT algorithm offers increased energy harvest from the PV array than other MPPT controllers. The FLEXmax 100 delivers both higher voltage and higher power, offering improved flexibility and performance.

The compact, outdoor-rated enclosure keeps dust and moisture from damaging internal components. With the addition of arc and ground fault protection, and rapid shutdown capacitor discharge, the FLEXmax 100 is the most versatile high power MPPT controller on the market. Configuring the FLEXmax 100 in your system is easy with 128 days of built-in data storage, smart programming wizards (MATE3s required), and connectivity with OPTICS RE, so you can monitor, command, and control from one location.

The FM100-300VDC is a top-of-the-line high performance, efficient and versatile charge controller for your advanced power system.
