Upgrade Invertor, Feed Existing AC Outlets?
My coach has a 130w OEM inverter next to the TV (above the passenger seat). It has 2 AC outlets. The TV and DVD/Blu-Ray player plug into it. All the other AC outlets are only powered when on shore p...

agreed. to do it clean, troublefree and automatic, you'll want/need a transfer switch and a subpanel. First you don't want a case of the inverter AND outside source going to circuits at the same time. Next, you want it to be reliable. And most important you want it SAFE.
I did it, I put the inverter in the pass through close to the batteries and the on/off remote in the living area. Ran the inverter out to a transfer switch which also goes to the 120V line. it is set up so it instantly transfers from 120V to inverter when 120V goes down but waits 30seconds to transfer from inverter to 120V. (on most transfer switches there must be a delay on one transfer)
The transfer switch output goes to a subpanel that is fed from a 30A circuit and ONLY feeds some of the 120V stuff, that way the inverter won't try to run the AC, the fridge on AC, OR the charger, or the HW heater. It only runs the other outlets.
If I loose shore power, and the transfer switch kicks in, the AC will drop out as will the charger and fridge and HW heater on AC.
It's nice now that it is done, but it isn't a easy DIY if you don't have a good gasp of wiring and codes and SAFETY requirements.
