When Fangpusun Xtender XTM pure sine wave inverter adopts distributed microgrid, solar panels and hydropower system are usually used to charge the battery. When the power supply is insufficient, the generator can be used as backup energy. In the aspect of enterprise power supply, micro grid based on photovoltaic power generation will gradually play an important role. For industrial parks, this kind of power grid has more economic advantages. XTM pure sine wave inverter and its ups bring great benefits to industrial production.
