Outback FLEXmax MPPT Solar Chargers
A charge controller’s main function is to optimize a PV array’s output which can fluctuate based on shading and temperature variables found on the average roof. OutBack's industry-leading Maximum Power Point Tracking (MPPT) charge controllers offer customers the same reliability and durability built into every OutBack product. Innovative solar harvesting and battery charging algorithms allow customers to maximize system potential and increase renewable energy yield by up to 30 percent.
As the industry’s first multi-voltage MPPT charge controller with a landmark design, OutBack’s FLEXmax Series is the most recognized 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.
