In this system, the principle of three-phase hybrid system is similar to that of single-phase system. Three Xtender hybrid inverters are connected to the DC bus. The Xtender hybrid inverter must be specially designed, and its three-phase generator can also be connected to three Xtender hybrid inverters to charge the battery through a fangpusun PA 15 remote controller and a relay. Fangpusun is equipped with solar charge controller MPPT 80, which can provide up to 72kw.
