A charge controller’s main job is to optimize a PV array’s output which can fluctuate based on shading and temperature variables found on the average roof. OutBack’s FLEXmax™ Controller is anything but average—so rugged and reliable that it’s used by NASA on solar arrays in high-altitude testing 20 miles over Antarctica.
FLEXmax Charge Controllers truly represent innovation in Maximum Power Point Tracking (MPPT) technology, which enables them to increase the yield from a solar photovoltaic (PV) array as much as 30% over conventional designs. At the industry’s first multi-voltage MPPT and a landmark design, OutBack’s FLEXmax series is the most copied controller on the market today. FLEXmax Controllers support a wide variety of system designs, battery chemistries, and integrate seamlessly in terms of system data management and programming.
The innovative FLEXmax MPPT software algorithm is both continuous and active, increasing photovoltaic array power yield up to 30% compared to non-MPPT controllers. 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 Charge Controllers incorporate the revolutionary features first developed by OutBack Power, including support for a wide range of nominal battery voltages and the ability to step-down a higher voltage solar array to recharge a lower voltage battery bank. A built in, backlit 80-character display shows the current status and logged system performance data for the last 128 days at the touch of a button. Integrated OutBack network communications capability allows FLEXmax Series Charge Controllers to be remotely programmed and monitored via a MATE system display and provides complete system integration.
