Hi, I'm in the process of building out my 2x EG4 6500EX inverters in split phase mode. I think I'm going to have them fully off-grid as opposed to what I was looking at previously of having the grid as backup...seems to be simpler for the time being. One of the things that always concerned me was what happens if one of the inverters fail and how that sudden failure and losing one leg can impact any 240v loads. I had an idea which involves placing both inverters in 120V mode in parallel, so basically 120V AC with 13KW capacity and using the 120V paired out from the inverters with an auto transformer to give me 240V split phase, and then running that auto transformer to my main panel. With this method, if one inverter fails, I still can maintain 240V split phase albeit at 6500W instead of 13KW.
I'm interested to hearing your thoughts about this approach. I'm in the IT field so I'm always mentally occupied about failure scenarios and redundancy.
