Can a 220 volt inverter be stacked?

They designed it to be stackable, to have more than one in parallel. But also to "stack" their output voltage so that you can have 110v plus 110v to get your 220v, and center between the two connected to ground. I have no experience with this inverter but I like their idea.

Do I need a 220V power converter?

It is also possible that your home already has 220v service in operation. Still, you may need the higher voltage for your appliances or devices to operate even better. You can use a voltage converter, or you could work with an electrician. If working with an electrician, you’ll find that:

How tolerant is a 110V inverter?

How tolerant the inverter is of imbalance on the 110v would be a question for the manufacturer to answer. There is another thing to consider. While the voltage across L1/L2 will always be the total voltage available, if you put a heavy load on L1/neutral and drag the voltage on that side down, the voltage across L2/neutral will go up.

How much voltage should a 230 volt inverter be?

The voltage is not required to be exactly 230 V. There is a tolerance. 5% (if that's what it is), gives you 11.5V either way. Anyway, I have set my inverter for our safety code, and I leave it to disconnect when it sees fit.

Can a 230 volt inverter go into backup/up mode?

If the inverter is set to SA grid code, it will only tolerate voltages of 230V±10%, which means that it would have disconnected and go into backup/ups mode when the grid voltage dropped to "196.5 V". Yeah I assumed there was some fine print I'm missing, thanks for clearing that up It is more about the voltage than the frequency

Should a solar inverter be prioritised over a grid?

If it is one of the common inverters that get used to feed power to the house, there should surely be some type of setting to prioritise solar over grid. The source is not the problem. The problem is that the inverter synchs the voltage to the incoming Eskom feed - even if I am running fully on solar
