This thing actually looks interesting. At this point I probably would not drop out of the EG4 ecosystem, but we are seeing a lot more options these days. I'd be curious how this bad boy would handle starting my HVAC, that to me is the biggest achilles heel on these units. Even in parallel they can fall over if you hit them too hard all at once. I just wish they would go on up to 50A (12KW) with these things. I really think 100A with two units would pretty much handle an all-electric home with no difficulty. I've found the EV is a big wrench in the gears I'm working thru now.
I for one would never dedicate an inverter for an EV, but 10KW should be about where you would need to be. Let us know how this thing performs.
