1KW Pure Sine Wave inverter chargers 1000W 12V 24V

This heavy duty 1000W low frequency pure sine wave inverter charger approved by CE standards. It is a combination of an power inverter, AC battery charger and AC auto-transfer switch into one complete system with a peak DC to AC conversion efficiency over 85%.

* Pure Sine wave output, heavy-duty and strong load capacity for inductive loads without damaging the equipment.

* Low frequency with toroidal transformer, less than 0.6A self-consumption, energy saving.

* AC/Battery priority modes enable it to work with backup power or renewable energy applicable

* Wide input voltage range

* 4ms auto-transfer switch, no shutdown for your computers

* Protection against over-load, over-charging and discharging battery, over-temperature, short-circuit.
