Prowatt SW2000 2000W True Sinewave Inverter Model# 806-1220

Is this a pure sine wave??

Does this have a built in fuse or circuit breaker? Or do I have to install one outside of it? Thanks!

What's the VA rating for this inverter? How does it handle inductive/motor loads?

Will this unit run solely off a battery bank like with a solar system or does it require an engine running to provide constant power to the batteries?
