OutBack Power | FLEXmax 80A | MPPT Charge Controller

Overview

OutBack's FLEXmax 80 uses a continuous, active MPPT algorithm that OutBack says can raise PV output by up to 30% compared with non-MPPT controllers. It supports battery banks from 12 to 60VDC and can step higher-voltage arrays down to charge lower-voltage batteries. Built-in OutBack network communication allows remote programming through a MATE display.
