WZRELB 5000W 12V DC to 110V AC pure sine wave inverter generator, as good as Grid power, 5000W continuous power, 10000W peak power, with LED displays for DC AC voltages. Dual US outlets. Fully Safety Protections: Over voltage, Low voltage, Overload, Short circuit, Over heat, polarity reverse protection(fuse), Ground protection from leakage of electricity. High quality pure copper inductance, filter the wave form, ensure the true pure sine wave AC output, safeguard your equipment. All big imported mosfets with strong driving capacity. Build-in intelligent cooling fan works according to temp and not load. Prolongs battery life. It is fairly quiet and only cycles on when the temp is over 66 degree Celsius. Reliable performance -- the 5000W Power inverter is equipped with extra thick (2. 0mm) PCB which greatly enhances the load capacity of the inverter. Home power supply.
