The FLEXmax series of charge controllers represents the latest advancement in Maximum Power Point Tracking (MPPT) technology from OutBack Power. These controllers feature the innovative FLEXmax MPPT software algorithm, providing continuous and active tracking that can significantly enhance the power yield of your photovoltaic array, with potential increases of up to 30% compared to non-MPPT controllers.

Equipped with active cooling and intelligent thermal management, both the FM60 and FM80 charge controllers can operate at their full maximum current rating—60 Amps or 80 Amps, respectively—even in ambient temperatures as high as 104°F (40°C).

Key Features:

  • FM60-150VDC charge controller with a 60 Amp output at 40°C.
  • Compatible with 12V, 24V, 48V, or 60Vdc batteries, supporting a maximum of 150Vdc PV input.
  • Utilizes a 3-stage charging algorithm to ensure a thorough 100% recharge of the battery bank.
  • Adjustable voltage settings enable versatile use with a wide range of battery types.

When you require a charge controller that delivers high performance, efficiency, and versatility for your advanced power system, FLEXmax MPPT Charge Controllers stand out as the optimal choice.
