SHUYI EP500 is a kind of home backup storage power supply which can provide power for the electrical equipment at home. Whole-house batteries have become increasingly popular with Asian, American and European households because they can mitigate the impact of power outages and make the most of solar energy. Typically, though, they're designed to be fixed in place, whereas SHUYI's home energy storage batteries are mounted on wheels like a portable air conditioner. This design provides users with great convenience. AC Rated Power Battery Capacity 2000W(Peak 4800W) 5100Wh Battery Cells Max Input LiFePO4 145VDC Rated Life Cycle Warranty 6000+ 3 years
