THOR Modified Sine Wave Inverters

Kinda false advertising here. This unit, and most others too, will not power your RV IF your neutral wire, in your rv, is connected to your negative battery terminal. So, look at your battery, If, a white wire is connected to your battery, this unit will not work. You then have to run an extension cord through a window to run your TV or any other 110 v power unit.
Great power to run a lot of things, nice unit, well made.
