ST1500 1500 Watt Pure Sine Wave Inverter – Heavy Duty, w. Transfer Switch.  

This DC-AC pure sine-wave inverter has models that convert 12/24/48 Volts DC to 1500 watts of AC power at 120 Volts, 60 Hz. This inverter is a high efficiency microprocessor controlled model designed to conform to the UL458 specifications. A built-in 16 Amp automatic transfer switch and 10 Amp circuit breaker are standard with this model. Battery cable lugs enable DC input connection. AC output is provided through a hardwire connection – no AC output sockets are available. Features include overload, over-temperature, short-circuit, reverse-polarity, low battery, under & over voltage protections. A low power saving mode is an additional feature to conserve energy. A 230VAC / 50Hz version is available by special order.
