I decided I would like to have 120 AC available in my motorhome when I am not on shore power without running the generator. I bought a 2500 Watt inverter on line and a 50 amp automatic transfer switch. Installing the inverter and the transfer switch became complicated due to space considerations.
I decided I could install just the inverter but I wanted to make absolutely certain I did not connect the inverter and shore power or generator at the same time. I know that would not be a happy event. But I wanted the inverter to power outlets inside the MH. I needed a way to wire the inverter into the AC system of the MH that would be fool proof. That is why the automatic transfer switch seemed necessary.
I have an epiphany at 3:00 an. Just install the inverter in the compartment with the 50 amp shore power cord. Use a 50 to 30 amp adapter and 30 to 20 amp adapter to connect the shore power cord to the inverter whenever I disconnect the shore power. That way I cannot connect the shore power and the inverter at the same. The automatic transfer switch already in the MH will insure that the generator will not connect when the inverter is providing AC.
I am returning the new automatic transfer switch I purchased for this installation and saving $150.
Having a transfer switch, would present even more problems, with forgetting to shed non-inverter loads.
What you have now, by simply plugging into the inverter with the power cord is the simplest
Naturally, you must remember to open certain breakers first, so they won't try and run off of the inverter.
A/C units.
Water Heater.
Converter.
Diesel block heater.
RV fridge, if applicable.
Microwave will run just fine, but not for long without depleting the batteries.
Since your inverter is plenty large enough, what do you have for house batteries???
Biggest disadvantage with your setup, is for not being able to use it, going down the road with the alternator keeping things charged.
Well, unless you can find a way for running the power cord inside.
