I will be transferring between shore power and the Inverter.

I assume the output of your transfer switch will go into your 30A electrical panel, right?

If so, that means when you switch over to your 2000W inverter, it will be powering ALL the circuits, including your AC & water heater.

I hope you have a large battery bank.

He doesn't have to turn the AC on. He can set water heater (and refrigerator) to propane. He has already said he will turn off the breaker to the converter/charger. What he is doing is imminently feasible.

So OP will have to always remember to throw several switches or risk dead batteries.

Plus, if the ATS is generator preferred and the inverter is connected to the generator side of the ATS, then OP will have to remember to also turn off the inverter when shore power is applied.

Why not just use a manual transfer switch?

Or, though more expensive, it sounds eminently more practical to buy an inverter/charger with a built-in transfer switch and wire it like so (with or without a sub panel), especially is OP's wife or friend(s) will also be responsible for switch throwing:

The only breaker I will have to throw when the ATS is in inverter mode is the AC. Since I don't use AC that often and never when on batteries I will just turn it off and leave it off till I need AC.

My Converter will be wired to the panel side of the ATS so it will only charge when in shore power side and not to conflict with the Inverter side.

A combination Converter/Inverter with built in ATS would be nice but they are very expensive. I
