Inverter（1000W-5500W）

Pv grid-connected power system includes PV modules, grid-connected inverter, meter and power switch board. The PV modules convert the solar energy into the DC power. Then the grid-connected inverter converts the DC power into the sine wave AC power which has the same frequency and phase with the grid voltage. The AC power feed-in the grid partly and the other power supply the local loads.  Solar grid-connected inverter STGC-1000W/2000W/3000W/4000W/5000W (Single-phase) 1.
