I installed a new 15Amp breaker in the 110VAC panel and connected the TT's Battery Charge Controller's 110VAC source to it. This way when I want to use the inverter, I just flip the breaker to the off position. If I were to redo this setup, I would install an Automatic Transfer switch between the inverter/shore-power and the 110VAC power panel. I would rewire the TT's battery charge controller and the TT's Air Conditioner to the Shore Power side of the Automatic Transfer Switch. This way both the AC and charger will only get power when connected to shore power.
Here is the link for a
30 Amp Automatic Transfer Switch.
They also have a 50 amp model if you have 50 amp service.
