Product Description

Customized explosion proof inverter 5kw to 200kw 


Explosion-proof low frequency off grid inverter solar system

PV Off-grid solar power generation system including solar panel array, solar charge controller, storage battery, Off-grid inverter, etc. In the sunshine, the solar panel convert the solar energy to DC power and charge the battery group by the charge controller. Then the off grid inverter convert the DC power into AC power for power supply the AC load.

Explosion-proof low frequency off grid inverter no battery system

Off grid without battery system consist of solar panel array/ wind turbine/ hydro turbine generator set/ others different kinds of DC power input and wide voltage off grid inverter. The solar panel or wind turbine convert solar/wind power to electrical energy, then wide voltage off grid inverter convert DC power into AC power to take the AC load, Inverter also can add AC bypass input switch, when solar/wind power is insufficient, inverter will automatically switch to AC bypass input power(AC grid or diesel generator) as backup to take load.
