This product can flexibly set AC-dominated power supply and DC-dominated power supply (such power supply form can be switched through LCD panel or communication background software):
1.When there is mains, AC-dominated inverter power supply is under mains output mode; in case of mains fault, AC inverter power supply automatically switches to inverter output.

2.DC-dominated inverter power supply is under inverter output mode during normal operation, and automatically switches to mains by-pass output during the occurrence of DC input fault.
