I can power everything in the home with 110 converted but 220 VAC is a path less traveled.
I need comments from folks who have done that.

Not sure what part of the world you live in, or what your grid power is like there.
We use 60 Hertz, 120/240 volt split phase here in USA. My grid power is unreliable, mostly due to falling trees, and poor Utility line maintenance.
I have 8,000 watts of Solar pushing power on to the grid, and 4000 watts Solar power charging a 24 volt Flooded Lead Acid battery bank.
2 Volt cells, 1200 Amp-Hours, twelve in series. The batteries run a series stacked pair of Outback Power inverters, with a 4KVA balancing Autotransformer across the output. This provides continuous 5 kilowatts 120/240 volt and can provide surge power of 10,000 watts for 5 minutes.
The OutBack power inverters have been in service continually since 2003, and have not missed a cycle. Usually one sleeps until the deep well pump kicks on, or convection oven, etc.
IF you want a single unit to make 240 volt AC, I think your choices are Magnum Power or VICTRON. both work well, but I've never heard of either running for a decade without failure or service. Running anything big, like well pumps, compressors, refrigeration, welders or amplifiers is VERY DIFFICULT with 12 volt batteries. the copper wire and massive parallel battery banks are expensive, inefficient, and hard to BALANCE.
I strongly recommend a 48 volt or 24 volt battery system if you plan to run refrigeration, washing machines or a well pump.. 12 volt stuff will not "get you there"
