DC/AC Inverters Type 20kw 3 Phase Grid Tie Solar Inverter

Grid Tie Solar Inverter with higher efficiency, lower loss, higher reliability which are
high-quality products are developed and produced by our company. The price ratio of BZS is the
most competitive one among the green power in the market.
BZS series convert renewable, advanced power (such as solar, wind, fuel cells, micro turbines,
batteries ) into electrical power that can be used as a primary or backup power source for homes
and small businesses to Industrial and utility applications.
PV grid-connected power system includes PV modules, grid-connected inverter, meter and power switch board. The PV modules convert the solar energy to the DC power, then the grid-connected inverter the DC power to 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 powers supply the local loads.
