Continuous Power 3000W. Waveform Pure Sine Wave. For the resistance load appliances, you can choose the inverter whose power a little higher than the appliances' work power. Surge Power 6000W. For example, a refrigerator in the normal operation of the power consumption is about 150 watts, but the starting power is about 1000 watts or more.
Tested good running at half load (1500w) Fan came on twice for short periods of time. Probably won't run it much higher than that to protect the MOSFETS. They are usually the first things to pop with any type of overload.
