Can you do some differential analysis?It could but I’m not sure how it’s getting there , I initially thought it was going back up the pv ground wire so I temporarily disconnected it but it did not help
Are the ac-in wires in proximity to the pv wires?One particular time is when I turn on the ac to the inverter , It trips every time
you could try to temporarily isolate the cables to see if that helpsThey are in the same gutter box under the inverters. They run parallel for about 1 foot with 4” of separation
It still could be the ac charger.Thank you both I will try this , I thought I had enough separation but maybe not . I was concerned it was just a flaw with the deye
I would route the pv elsewhere.They are in the same gutter box under the inverters. They run parallel for about 1 foot with 4” of separation
I have it off temporarily right now and it does work as expected.Just had a thought.
If the relay in the transfer switch was marginal it would be pretty similar to a telegraph key.
Also is there a configuration option to disable arc fault protection?
If yes it would be a good baseline to make sure it actually works as expected.
How about the dc from the battery in the gutter box ?I would route the pv elsewhere.

I disconnected the ground wire that runs parallel to the pv wire to the roof as a test .But you said it tripped even with PV disconnected? If so, likely wouldn't even succeed in masking the issue you're having.
It is the pv ark fault but I can tell it’s from ac loads or switching . If I have the ac off coming into the inverter and then flip it on , it triggers an arc fault every time .Is that PV arc-fault protection that is tripping? Depending on AC loads and AC input?
It’s not bonded to groundIs battery negative terminal grounded? Is it supposed to be according to manual? That is one more section of wire which could affect radiated and conducted interference.
I had my 8 “ gutter box nice and clean but when the electrician got gone it was just lacking a little spaghetti sauceGood thought, try moving battery cables away from PV (and any other) cables. Keep battery + and - cables tightly together.
