    OutBack Power FLEXmax MPPT Charge Controllers

    FLEXmax FM100-300VDC MPPT Charge Controller

    OutBack Power’s new FLEXmax FM100-300VDC medium-voltage charge controller accepts higher voltages from PV arrays to allow for longer wire runs with reduced wire sizes. It can be used to charge 24 or 48 VDC battery systems from PV arrays with voltage up to 290 VDC, but can withstand voltages up to 300 VDC without damage. Output is rated at 100 A at 25°C (with deration to 80 A at 40°C), with four-stage charging and an operating temperature range of -20 °C to +60 °C. NEMA 3R design allows for outdoor installation.

    The FM100 can be used in negative, positive, or floating ground systems. Ample wire bending space and oversized terminals provide easier installation with larger gauge wire, and servicing and replacing all power components can be done with the unit mounted on a wall and attached to conduit. It has integrated PV ground fault detection, interruption and indication, eliminating the need to have an external GFP device. Built-in AUX relay has a 12 VDC output of up to 250 mA.

    As the FM100 has no onboard display, an OutBack Power MATE3s or AXS Card MODBUS/TCP interface is required to program this controller and access the 128-day data-logging history, and the programming and monitoring system functions.

    The RTS remote temperature sensor is standard with the FM100; and is optional with the FM60 and FM80. FLEXmax charge controls connected to an OutBack inverter system with a HUB can use the system RTS connected to the master inverter.

    All FLEXmax charge controllers are covered by a 5-year standard warranty and are listed to UL 1741 and C22.2 No. 107.1 for the U.S.A. and Canada. The FM100 is also listed for IEC 62109-1
