SUNGROW Multi-MPPT Solar Inverter

String inverters transform the direct current (DC) from your PV panels into an alternating current (AC) that can be fed into the electrical grid.
String inverters are mostly used in residential and commercial solar projects such as rooftop, carport, ground mount and tracker installations. Sungrow string inverters come in a power range between 2.5 kW and 250 kW.
