OutBack Power, FlexMax-80, MPPT Charge Controller, 80A, 12/24/48/60VDC, 150VDC, LCD Display, FM80-150VDC

The OutBack Power FlexMax-80 FM80 150VDC MPPT charge controller is the latest innovation in Maximum Power Point Tracking (MPPT) technology. The innovative FLEXmax MPPT software algorithm is both continuous and active, increasing your photovoltaic array power yield up to 30% compared to non-MPPT controllers. Due to active cooling and intelligent thermal management cooling, both FLEXmax charge controllers can operate at their full maximum current rating, 60 Amps or 80 Amps respectively, in ambient temperatures as high as 104°F (40°C).

Included in all of the FLEXmax 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. 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 FLEXmax series charge controllers to be remotely programmed and monitored via a MATE system display and provides unrivaled complete system integration.

OutBack's FLEXmax-80 MPPT charge controllers are the only choice when you demand a high performance, efficient and versatile charge controller for your advanced power system.
