Tesla finally was able to come and check this. They were able to locate one of the 'disconnected' strings and were able to quickly fix it. Energy production is now in the expected range. I now see power from all the three strings. Thanks everyone.

I am not that familiar with the inverter setup. I have 4 wires coming into the inverter. Are you saying that my inverter is using 3 MPPT channels?

That’s my suspicion. So far, that theory seems to be lining up with all the data I’ve been seeing. Just have to get Tesla to send someone up that roof and take a look at it.

I asked Tesla to send me the final drawings, as they made a few last minute changes to my project. Per their drawings, the two strings should be configured as follows: But I was able to get string readings that looked like this: {'A': {'Current': 9.11, 'Voltage': 271.2, 'Power': 2449.0...

Thank you very much for all the info. Will keep you posted.

I got another photo of the exterior junction box.

I completely understand your suggested approach and totally agree. My intent is to not DIY this issue or to tell Tesla what to do. I am just trying to understand the range of possibilities for this, so I am better prepared. Thanks for sharing the info.

I just took a few more photos of the inverter wiring in different angles. You mentioned upstream issues. One other thing I didn’t mention was that initially they intended to put the Tesla inverter outside, but when they changed the design to powerwall plus that comes with an inverter, they...

Do you know what Tesla had to do resolve your issue? Did they have to re-wire the inverter or panels ? Any info you could share will be helpful. Greatly appreciate the info you’ve been sharing.

Thank you very much for this info. I am noticing the same phenomenon you described about both strings reporting almost equal current and voltage. My panels are Tesla panels (changed by Tesla from Q.Cells to Tesla panels a week before installation). I have a service request open with Tesla...

No. 1 inverter.

I believe the Tesla pw+ inverter is a 7.6 Kw

It tends to cover one panel past 2 pm. I believe they took that into account and might have done a parallel configuration to compensate for that. Not 100% sure. But I should see a peak before 2pm and that hasn’t crossed 5.6kw yet.

It looks like I have two strings (String A connected in series and String B connected in parallel). Is it possible that one of the rows in String B that is connected in parallel is improperly connected or that row of panels is not working/producing? Just trying to rule out obvious issues.

The roof pitch for the south side is 42 and for the west side is 40.

Here's the wiring inside the inverter. For a view of the panels and inclination:

I have a new 8.4 Kw Tesla Solar Panel system (21 panels) with 2 PW+. It's been up and operational for over 2 months. The peak solar production I've ever seen this system produce is 5.6Kw and a total of 35.6Kwh so far. I live in Texas and we've had some pretty good sunny days and this is the peak...
