Outback Power Systems FM80 Charge Controller

The FLEXmax FM80 charge controllers are the latest innovation in Maximum Power Point Tracking (MPPT) charge controllers from OutBack Power Systems. The innovative FLEXmax MPPT software algorithm in the FLEXmax FM60 is both continuous and active, increasing your photovoltaic array power yield up to 30% compared to non-MPPT controllers. Thanks to active cooling and intelligent thermal management cooling, the FLEXmax FM80 charge controllers can operate at their full maximum current rating of 80 Amps, in ambient temperatures as high as 104°F (40°C).

Included in the OutBack Power Systems FM80 Charge Controllers are the 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. You can wire your array up to 60 volts and feed a 12, 24, 36 or 48 volt battery bank. A built-in, backlit 80 character display shows the current status and logged system performance data for the last 128 days at the touch of a button. The integrated OutBack network communications allows the FM80 Charge Controllers to be remotely programmed and monitored via a MATE system display and provides unrivaled complete system integration.

OutBack Power Systems FM80 Charge Controllers are the only choice when you demand a high performance, efficient and versatile charge controller for your advanced power system.
