When I received the device I was skeptical because of its weight which is very light. I hooked it up to my 48v battery and decided to do an inductive load test to get the best results. at 1500 watts the device warns that the output power is too high, so "permanently 2000 watts" cannot be achieved. Like most inverters I've tried, I opened it up and found that the board clearly says "p1500s2a", indicating it's a 1500w inverter. Another theft by deception. Avoid this unit.
