I noticed an odd behavior with my power system recently. In the past 1 week, 5 out of 7 days, there was no generation in the morning till 15-30 minutes before 10am. The graph short sudden start of generation right from 5kW or so. But 2 of those days, they work normally gradually increased from 0. The weather has been clear for the whole week. I am in San Jose and. Normally generation would start before 8am.
When I look at my Tesla app, similar thing has happened, but less frequently in the month of July.
I have tried restarting the inverter twice earlier in the week and by chance I think the first time generation started shortly after that but both around 9:30am. One of those time while chatting with Tesla support. And they simply said "looks like problem is solved, is there anything else we can help" and wanted to hang up. After I insisted it's not normal, they said they would look into it but today I got an email saying my generation looks normal.
I tried restarting the inverter on a 3rd day earlier in the morning and saw that the MySolarEdge app is telling "P_OK: 35 of 36 Optimizers Communication". That number increased from 1 slowly until it reached 35 and stuck. Also under Error Log it shows "Error 18x86: Isolation".
This morning, without restart the inverter, I logged on to MySolarEdge app and saw the same thing again, 35 of 36, and another Error 18x86: Isolation, and no generation.
While waiting for a call back from Tesla, and writing this, generation started at around 9:35am.
Could this be a bad cable (caused by squirrels, broken solar panels which I have a few by golf balls) or is there anything else I could check?
