Product information

The FLEXmax charge controllers are the latest maximum power point tracking (MPPT) charge controllers from OutBack Power Systems. The innovative FLEXmax MPPT software algorithm increases your photovoltaic array power yield up to 30% compared to non-MPPT controllers.

With active cooling and intelligent thermal management, FLEXmax charge controllers can operate at their full maximum current rating in ambient temperatures as high as 104°F (40°C). FLEXmax controllers can be used with battery systems from 12 to 60 VDC with PV open-circuit voltage as high as 150 VDC. The controller's set points are fully adjustable to allow use with virtually any battery type, chemistry and charging profile.

The OutBack FLEXmax controllers allow you to use a higher output voltage PV array with a lower voltage battery – such as charging a 12 or 24VDC battery with a 48VDC PV array. This reduces wire size and power loss from the PV array to the battery/inverter location and can maximize the performance of your PV system.

They come with a display of PV system performance that is easy to use and understand. The 4-line, 80-character backlit LCD display is also used for programming and monitoring the system’s operation. They can be connected to the OutBack MATE series of system controllers and displays to allow monitoring of up to eight controllers from locations up to 300 feet away. The MATE also includes an opto-isolated RS-232 port for connection to a PC for data logging and system monitoring.
