SP700 series 700 Watt Pure Sine Wave Inverter – Heavy Duty.  

This DC-AC pure sine-wave inverter has models that convert 12/24/48 Volts DC to 700 watts of AC power at 120 Volts or 230 Volts. This inverter is a high efficiency microprocessor controlled model that is certified to the UL458 standard. This unit has dual NEMA 5-20R GFCI receptacles – other types of input connectors and output AC sockets can be factory ordered. It can also be hard-wired directly to a DC source. Battery cable lugs are also included. Features include wide input voltage, wide operating temperature, RS232 communications and optional Transfer Switch. Protections include overload, over/under temperature, short-circuit, reverse-polarity, low battery, over/under voltage protections. A low power saving mode is an additional feature to conserve energy.
