I'm planning to use a similar wiring scheme with a couple of modifications. I'm curious your thoughts. The main change will be eliminating the 100 amp bypass and wiring the combiner panel directly to the loads panel and wiring the main panel with a 200 amp breaker and accordingly sized wire to...

If you ever do decide to make the switch (or if anyone reading is planning to do something similar), I did a little research on it and was able to find this...

Thank you. This is really helpful.

Hi all, I'm planning on installing a residential solar system on my house with the EG4 18kpv inverted and powerwall. Upon reviewing the manual, I found this diagram. Prior to viewing this diagram, I was planning to install the system like this: I'm trying to understand the need for the...

Thanks Brayden. So my plan is feasible, but I would have to completely shut down power to my main panel in order to work my solar system. I've also been watching this video which might be a better alternative than my drawing while maintaining the benefit able to maintain power to the main...

The main benefit would be cost savings - a little over $2000 cheaper on the two 6000xps. You can use an interlock breaker as a manual transfer switch. $20...

Thanks for the response. So Grid is only an import circuit and Load is only an export circuit. If that's the case, would I be able to wire both Grid and Load into my main panel and have both circuits active at the same time? Would this create any risk of unintentionally back-feeding the grid...

I'm looking into downsizing my system. Is it possible to substitute the EG4 6000xp (potentially two) and do the same wiring with grid and load wired to my main panel using an interlock breaker so that load and main service are never on at the same time? To clarify my question, does the Grid...

Yes. It's not a breaker so it can't be turned off. You'd have your breaker on your 200amp loads panel, which could be interlocked to your 100 amp circuit coming out of your combiner box. If you wanted the actual transfer switch, instead of the interlock, you'd have to spend for the 200 amp capacity.

Noted. I can not run Load and Grid to the same panel at the same time without back-feeding the grid in a grid down situation. If I purchase two EG4 6000XP's and parallel them, I know this would double my output from 6000W to 12000W. Does this also double the grid passthrough from 50amps to...

As to point 3, this was a local requirement for my incoming service provider. You'd need to check with them and local code to see if it is a requirement in your situation.

Here's a drawing to make it simpler.

What product are you using for the combiner panel?
