20KW PV Grid-Connected Inverter with 3 phase 380VAC
Summarize
The grid connected inverter can be used with a connection to grid or power lines. This type supplies the loading appliances with electric power produced by photovoltaic systems.
The advantage of grid-type is not to worry any power waste, because by connecting inverter to grid, it can save
any surplus electricity.
