Thanks for the suggestions and comments!
What do you mean by just 200A passthrough? Can you provide a simple schematic? Tesla isn't providing any answers to my questions and it's really hard to communicate with them.
For the 125A suggestion:
1) does section 6 and 8 both have to have same breaker size? The load center is the section 6 / (E) ? and can be left at 175A or 200A?
2) I assume the 125A is for section 8 in (A) of the schematic?
3) Any 120% rule implications?
Thanks again!
For what all this stuff costs, do it right, replace the main panel. I did mine.Likely the correct solution here is to replace the main panel but you can probably make it work ok as a partial home backup system.
As you have, many main panels especially the more compact and center-fed versions cannot take large branch circuit breakers, so it sounds like 125A is the largest breaker you can supply.
As it is designed now, your Powerwalls could supply some additional power above the 125A available from the grid while they are charged.
It might be worthwhile looking at the loads you are backing up, or taking a second look at your load calculations. Your calculated load isn't that far off the ability for a 125A breaker to supply it.
Likely the system installer will consider setting the PCS controls such that you don't overload the busbar or the 125A breaker.
He would have to upsize the main breaker in his New backed up loads panel.Likely the correct solution here is to replace the main panel but you can probably make it work ok as a partial home backup system.

Hi, in your case, what breaker size did they use in your distribution panel? In the schematic they gave me, they put a 175A breaker in both the main panel (which is the one which "doesn't" physically fit") and one 175A breaker in the distribution panel where all the loads are relocated. I wonder why they need that 175A breaker in the main panel. Can't they just use the existing 200A breaker in there. Then my setup sounds like yours. Anyway you have a schematic you can post? It's a blackhole with Tesla...no feedback for week now from them.What they did for our system is removed all loads from our 200 amp panel with meter base. All they left in that panel was the disconnect and a 200 amp breaker at the bottom that goes to the gateway. Then they put in a new panel fed exclusively by the gateway and moved our existing loads to it.
I’m not sure this information helps in your case. Posting it in case it does.
16.3KW of solar w/ Tesla inverters and 4 PowerWalls.
My challenge is that I asked Tesla what specs etc. I need if I need a main panel upgrade and I get zero response from them. They claim they are working on it...for about a week now. I don't know specifically what to ask the electrician to do and need some confirmation as to what the electrician suggests would even meet Tesla spec. Other electricians want Tesla feedback to confirm before performing a job.For what all this stuff costs, do it right, replace the main panel. I did mine.
And if I could just have put everything in one panel.
