I currently have my entire house running off of one EG4 6000xp (running beautifully) and the only thing left to move over to solar is my AC unit with a soft start. I'm pretty sure it will be too much, but if I give it a try, what would be the worst case scenario? What actually happens if you try to pull more than 3000 watts on one or both legs of an EG4 6000xp assuming it's longer than the 3 or 5 second surge capacities? Will it:
1) Damage the inverter?
2) Go into fault and shut down?
3) Continue running, but pulls extra power from the grid as needed?

Pretty sure it goes into bypass mode. Therefore, you would need to keep the total draw less than the breaker feeding the 6000xp.

One time I tested with my 5 ton AC (both legs, 240v, without a softstart). The unit went to bypass at the startup for a second and switched back to EPS without any issue. Pretty neat. I don't recommend using it without a softstart though.

#3 (sort of). It will switch to pure bypass mode until the load is less than the inverter capacity for a few minutes - then it will switch back to running the loads off the inverter. I have a 6000xp and it does exactly this when I turn on the dryer.
