The only choice when you demand a high-performance, efficient, and versatile charge controller.


OutBack Power FLEXmax MPPT Charge Controller - 80A (FM80-150VDC)

Capable of operating at its full 80-amp rating in ambient temperatures as high as 104°F, and with battery systems from 12 - 60VDC with open-circuit voltage as high as 150VDC, the FLEXmax MPPT Charge Controller from OutBack Power is one of the most versatile controllers we've found. Its advanced software increases your photovoltaic array power yield up to 30% compared to non-MPPT controllers.

With revolutionary features first developed by OutBack Power, including support for a wide range of nominal battery voltages and the ability to step down a higher-voltage solar array to recharge a lower-voltage battery bank, the FLEXmax MPPT Charge Controller is the only choice when you need a high-performance - yet versatile - charge controller for your renewable energy system.

A built-in, back-lit, 4-line, 80-character display shows the current status and logged system performance data for the last 128 days at the touch of a button. Integrated OutBack network communications allows the FLEXmax to be remotely programmed and monitored via a MATE system display, and provides unrivaled complete system integration.
