FLEXmax MPPT Charge Controllers are the only choice when you demand a high performance, efficient and versatile charge controller for your advanced power system.

Thanks to active cooling and intelligent thermal management cooling, both FLEXmax charge controllers can operate at their full maximum current rating, 60 Amps or 80 Amps respectively, in ambient temperatures as high as 104°F (40°C).

FlexMax FM-80 Features:

• FM80-150VDC charge controller 80 Amp output @ 40C
• Can be used with 12V, 24V, 48V or 60Vdc battery with a maximum of 150Vdc PV voltage
• The 3-stage charging algorythm ensures 100% rechage of the battery bank
• Adjustable voltage setting allows for use on a wide range of battery types

FlexMax FM-80 General Specs:

• Dimensions (inchs): 19 x 9.5 x 8.5
• Battery voltage: 12/24/36/48/60
• Power (Watts): 5750
• Weight (lbs): 15.5

The Outback Power FLEXmax line of charge controllers stand out among their competition as one of the very best and most versatile controllers available.

OutBack’s advanced MPPT algorithm delivers as much as 30% more power to your batteries vs standard PWM controllers and other types of chargers. The maximum power point tracking (MPPT) allows the unit to determine the best combination of voltage and current to maximize the amount of power it can send to your batteries.

In addition to increased power and efficiency, this also allows you to design a more efficient solar array that takes advantage of a higher voltage than your battery system voltage. The FM80 can handle up to 150 Volts DC from the solar array, which is stepped down to the battery bank voltage.
