The biggest problem I see using a 12v to 220 inverter would be when I'm using a generator or plugged into 120v. The converter would have to charge the batteries at a rate the inverter is pulling from the battery. Doesn’t sound like a good idea.
Is the best thing to get an inverter charger with auto transfer with an attached autotransformer.
Is there an all in one unit that can give me split phase 240 and 120, auto transfer and charge? I know I’m asking a lot for a single unit to do, but would make my life simpler.
The best solution, at least in Victron world, would be a single MultiPlus or Quattro and an Autotransformer - assuming you have a 30A rig. If you have a 50A rig, you have the option of a 240V MultiPlus or Quattro with an Autotransformer to handle your 120V loads, or a pair of 120V MultiPlus/Quattros and an Autotransformer would only be necessary if you want to be able to run your air conditioner on any input source without inverting and charge using the full capacity of the inverter/chargers.
Magnum makes a MSH3012RV that you'll probably run across, but I'm pretty sure both legs are in phase with one another, so it won't actually produce the 240V you are looking for. And there would be a host of other issues you'd have to work through with it.
