Ahh now I see it.
Good thing that's not ecoflow magic smoke 😉
 
5.5 kw solar
Growatt SPF-5000-ES
Auto transformer
One server rack battery (so far)
Peak solar output so far was 4k.

Growatt and auto-transformer! You don't say!

Now that I think we have agreement on how to protect an auto-transformer, is that how you did it way back when?

Nope
That one was "T" tapped in the loads panel.
Only has short protection. But loads are well balanced.
Never more than 3a on the neutral.

The screen under the transformer is monitoring the neutral current.

It almost looks like top left breaker says, "Autotransformer".
If so, wouldn't that be a lost-neutral risk? (At least if manually switched off.) Appears to be a "do as I say, not as I do" situation.
 
The cable management you used looks convenient, but not something we could get away with if being inspected.
Or is it kosher for protection of something like Romex?

That breaker is the refrigerators in kitchen.
Transformer is connected to the main lugs.
The backfeed main is the only thing that turns it off.

Always lol
I take liberties for testing. I don't recommend them to others.
 
It wouldn't have taken all day, if I hadn't found that can of black spray paint. lol
