Hi.
2. Why does this ATS refer to itself as a 120/240 ATS- is it because there is 2 hot 110 leads and 1 neutral? Technically 240 but is anything actually running 240 or putting out 240 (generator?).
You got it. the ATS works on either 120 or 240 volt systems.. Don't worry about that. The generator likely only puts out 120 volt by the way.. Just so you now (Not guaranteed but common) the L1-L2 voltage is zero or very low.
3. I'm installing an inverter. Can I just install an ATS where the generator leads connect to the stock ATS, and have the inverter and generator come into my add on ATS, then go out to the generator input on the stock ATS?
NO.. you really should either get an inverter with pass through or install a 2nd Sub panel" With a inverter of 3600 watts or less I'd go with a 30 amp RV type Sub panel and a 30 amp ATS.. Feed the GENERATOR Terminals on the ATS (yes the generator leads) from a 30 amp breaker in the MAIN Breaker panel The Inverter hooks to the "SHORE" terminals.
Why. This will cause the switch to switch to SHORE when you have it and drop back to INVERTER when you do not.
If you get an inverter with a built in transfer switch (Best kind) They can be set in UPS mode.. a Television or microwave won't even blink.
YOU DO NOT want the inverter powering the water heater. Air Conditioner or the Converter...
Another option is an INVERTER/Charger.. Install as above but disable the converter. that is on the rig now. Odds are the "Charger" part of the inverter is way better than most low end converters
And good luck.. Be sure to use heavy enough wire and enjoy.
