EG4 feeding subpanel - any issues you can see?

You still rolling your own?

well if you find any eg4 6000xp's for $800 let me know

For that price, they would have to "fall off of a truck".

Very true.

*sitting here still thinking it'd be great for that kind of deal for a 6000XP*
anyway.
Solar to add. Battery capacity to add.
Expenses expenses.

I'm installing a EG4 6000XP just like OPS is - I have one question on the sub panel - that has circuits that only will powered via the inverter. Does code require THAT sub panel to have a main breaker - or does the LOAD breaker on the inverter that feeds the sub panel sufficient to satisfy any NEC codes?

The load breaker at the inverter is sufficient.
As long as the conductors and panel bus are rated for at least the same as that breaker.

Thanks for that confirmation - very much appreciated...

FWIW, the 6000XP spec claims it can run at a 100% imbalanced load, that is, it can run 3000w sustained on one leg. I wonder how much that spec can be trusted?

That is compared to the 18Kpv spec that states up to 4000w imbalance (out of 12 kW total).

In all fairness yes, it seems to be able to support 3k per leg no problem. We've run equipment that pushes that and the inverter dumps. I've mangerd to map out our curcuits and we can move things around to avoid an overload. But it would be nice if we didn't have to think about it.

my 2 cents - when our inverter takes a dump - the breakers never trip - it's just the inverter going off line.

The trip level of the inverter is lower than the trip level of the breaker.
The inverter will always trip first.
