3000va Pure Sine Wave UPS off-Grid Solar Inverter

Features:Pure sine wave outputCPU control technology; SCM controlStrong ability of impact resistanceWide input voltage range: 90-280V; four step AVR (three step boost, one step reduction voltage)Protection against overload, short-circuit, overvoltage, under-voltage and over-temperature, etc. Anti reverse connection protection and high-low voltage protection(option)Special overload protection: when it is overload, it will lock the unit automatically,when it restores,it will restart the unit automatically again.Strong inverter ability. It can change frequency immediately and it is able to drive the inductive load such as air conditioner, refrigerator, motor, etc.Powerful charge current: 500 W up to 15 A, 1 KW-4 KW up to 25 ALED or LCD display (option)Meet the need of different power supplyUse MOSFET and IGBTIntelligent battery management; provide the battery overcharge, discharge protection extend battery lifeApplication:
Apply to television, refrigerator, battery furnace, fan, microwave oven, air conditioning and other household devices.Specifications:
