Product Overview

Outback FM100-300VDC-AFCI FLEXmax MPPT Charge Controller 100ADC 300VDC /AFCI / 24VDC Systems: 3500W /48VDC Systems: 5250W / 60VDC Systems: 7000W

The FM100-300VDC is a top-of-the-line high performance, efficient and versatile charge controller. The advanced FM100 MPPT with AFCI eliminates the possibility of false arc-fault tripping, ensuring less downtime and loss of PV production.

The FLEXmax 100 charges your batteries faster. This allows you to sell energy to the grid faster, and maximize your return on investment. The FLEXmax 100 has the best price to power ratio on the market.
