Pure sine or standard inverter

Posted by SoundGuy: To date I have this inverter wired to feed the trailer "whole house" so I can plug these fans (or anything else) into any receptacle in the trailer but that does require me to first turn off the converter, force the gas to fridge, turn off the water heater electric element, and go outside to plug the trailer's main service cable into the inverter. I'm now planning to install a few dedicated receptacles in the camper (one of each side of the bed and another by the kitchen galley) which I'll feed directly from the inverter output receptacles. That should make for much simpler use than my current "whole house" wiring scheme - just turn the inverter on with the remote panel located inside the camper and plug into one of those dedicated receptacles.

Why don't you put in a subpanel and a transfer switch. Easy to do and makes life much simpler.
