COTEK 2000 Watt 48V PSW Inverter with Transfer Switch ST2000-148

This high efficiency microprocessor controlled DC-AC inverter converts 48 Volts DC (Nominal) to 2000 watts of pure sine-wave AC power at 100/110/120 Volts, 50/60 Hz. The unit comes with a built-in 35 Amp transfer switch and 35 Amp circuit breaker. Input battery cable lugs are provided and the AC output is obtained through hardwire connection. Features include overload, short circuit, over-temperature, under & over voltage protections, low power saving mode to conserve energy. The unit is e-13/ CE / FCC approved and the safety standards of the unit conform to UL-458 specifications.
