Products > Controllers > MPPT Controllers


MPPT (Maximum Power Point Tracking) charge controllers allow your solar modules to operate at their peak output voltage, improving their performance by as much as 30%. The controller harvests power from the solar array at the maximum voltage and converts it down to battery voltage, boosting charging current (Amps) in the process.

Maximum Power Point Tracking controllers are designed for use in larger solar module systems, where the modules are configured in long series strings to maximize voltage and amps output. Some models are designed solely for use with solar modules, while others can be used in solar, wind and hydro systems.

The FLEXmax Extreme’s advanced thermal engineering provides full power output from  -20 to 45°C without requiring a cooling fan. Because the passively cooled unit can be sealed, circuit boards and other sensitive electronics can be fully protected from dust, dirt, insects, and other external sources of contamination. The FLEXmax Extreme Charge Controller can not only go anywhere, it can also get there faster by saving precious installation time. It is a fitting companion to OutBack’s renowned sealed FX inverter/charger line and demonstrates the company’s ongoing commitment to providing clean, reliable power anywhere it has the potential to transform lives.

  • Environmentally-rated outdoor enclosure

  • Solid-state, passively cooled design for quiet operation

  • Sealed architecture for long-term reliability

  • Easily integrated AXS Card/Modbus/TCP interface

  • Remote battery voltage sense improves battery charging performance
