China Low Frequency Pure Sine 1000W 12V Power Inverters

Low Frequency Pure Sine 1000w 12v power inverters
This 12V DC inverter with max 70A charge current.
Pure sine wave output, this inverter built in charger and transformer
This inverter available in 12V/24V/48V, 1KW to 6KW
This inverter with pure copper DC terminal port, to protect rust, and it can load large current.
This DC inverter with more functon as below:
Durable construction for long life under extreme environmental conditions
Low idle current (less than 1 watt) conserves energy when no loads are present
Soft start capability for starting heavy loads
Built-in starting control circuits for two- and three-wire generator starting systems
Simplified controls with a snap-on cover that protects settings from being accidentally changed
Better thermal performance allows full output power to 50° C (122° F) without de-rating
High surge capacity starts more difficult loads and handles overload conditions reliably
Durable powder coated, corrosion resistant steel chassis
New digital display shows kilowatts (kW) when inverting and AMPS (A) when charging, plus incorporates a robust ON/OFF switch and status indicators
70-AMP automatic three-stage battery charger (bulk, absorption, and float) and battery equalization with remote temperature sensor for increased performance
New power factor corrected (PFC) charging, combined with a more sophisticated multi-stage battery charging algorithm, reduces electricity draw and generator run-time
