Inverter which converts DC (direct current) into AC (alternating current), we use pure sing wave inverters. There are three types of inverters, On-grid inverters, off grid inverters and hybrid inverters. In On grid inverters we have SMA, GoodWe, Huawei, Solis and in hybrid inverters we use Infini and Infini plus inverters. In off grid inverters we use Crown, Maxpower and Inverex.
