FD590 series solar pump inverter adopts MPPT (Maximum Power Point Tracking) and excellent motor drive technology to maximize the power output from solar panels. FD590 inverters are compatible with both AC and DC input, and the AC output can be used for various kinds of normal AC pumps. When the solar power is not available, or the sunshine is not strong enough to drive the pump, the inverter could be automatically switched to single phase or three phase AC input power, such as generator, grid power. FD590 inverters are equipped with overall protection function (self-checking functions for dry running,weak sunshine, full water level, etc.), motor soft start and speed control functions, with perfect function, easy operation and installation. FD590 inverters can also support remote monitoring and control function, which can monitor all operation data and fault information of the inverters.
