Description
Outback FLEXmax80-150VDC 80 amp MPPT Charge Controller |
The FLEXmax80 (FM80) is the latest innovation in Maximum Power Point Tracking (MPPT) charge controllers from OutBack Power Systems. Its innovative MPPT algorithm is both continuous and active, increasing your renewable energy yield up to 30%. Thanks to enhanced cooling, the FM80 can operate at its full 80-amp maximum current rating in ambient temperatures as high as 104°F (40°C).
Array size can be up to 1,250 watts when charging a 12-volt battery; 2,500 watts when charging at 24 volts; and 5,000 watts when charging at 48 volts.
Comes standard with an easy-to-use-and-understand display of PV system performance. The 4-line, 80-character backlit LCD display is also used for programming and monitoring of the system’s operation.
They can be connected to the OutBack MATE system controller and display to allow monitoring of up to eight MX80 controllers from a distant location – up to 300 feet away. The MATE also includes an optoisolated RS232 port for connection to a PC computer for data logging and system monitoring. ETL Listed.
