Product introduction:
Photovoltaic reactor is photovoltaic inverter reactor. Solar photovoltaic power generation system USES solar photovoltaic modules to convert solar energy into direct current energy, and then inverts direct current into alternating current through inverter. The main purpose is to suppress the influence of high frequency harmonics in dc-ac transformation on the power grid, reduce the harmonic current, and make the inverter output AC current meet the requirements of grid connection.
