You are correct, the PW+ CT is indeed in the upper left corner, I had to move the wires aside and peek behind it, but it's there! Regarding shading, I've been taking a close watch on the two strings attached to the standalone inverter, and your theory was correct - MP5 is shaded at 2PM. It's on...

I agree with this - I didn't see anything in the PW+ inverter that looked like the CT in the GW, and it would make sense that Tesla wouldn't put one into the PW+ inverter since the functionality is already there.

Thanks, you're correct. I opened my gateway and found it (it appears gray in the photo, but it's actually black - this was taken in bright sun).

At 11:25AM this morning, this is what I measured: Tesla App = 5.0 kW pypowerwall (B+C+D) = 2.285+0.930+0.831 = 4.046 kW PVWatts (July 1) = 6.1 kW So the Tesla App reports a value closer to PVWatts than pypowerwall, but still definitely lower. Thanks for the info on the CT; for some reason I...

This makes sense. So if there is a Powerwall and standalone inverter in a system like mine, the App has to combine the data from the solar CT and from the Powerwall to get accurate power information. So the 726Wh that I calculated in my previous posts could indeed be the standalone inverter's...

No, pypowerwall and the Tesla App don't match. I just checked 11:00AM Monday pypowerwall vs Tesla App, and the difference was 726Wh. Is this difference the output of the standalone inverter? I'm getting very confused.

Nice call! The Tesla App GUI shows 4.8kWh at 11:00AM Monday. Does this mean the standalone inverter's output (MP2+MP5) was 726Wh? Both the app and pypowerwall I think should reflect all the string outputs. But all of this is very confusing so I'm not sure. For the PVWatts plot I picked a...

Thanks for the feedback, I agree, I think output is low on mine. My PVWatts calculations matches Tesla's "commitment", and the actual performance for June is about 30% below this. Time to go argue with Tesla again!

I also tried what you mentioned a few weeks ago (power cycling the standalone inverter, and I was able to connect to it via browser and 192.168.2.1. I recall it came online after a couple of minutes (2 or 3?), but stayed online for only about 15 minutes. It was very annoying and time consuming...

That is exactly what I figured as well, thanks for the confirmation.

Thanks for the detailed input. I was wondering about just these details and you've answered some questions I had. So there is just no way to get data from the standalone Tesla inverter with pypowerwall (I'm a new user and still learning)? The earlier data was taken at 11:00AM, so all panels...

No worries, I really appreciate your detailed feedback!

Could you clarify? Both PVWatts and the Tesla app show peak production at noon, with 11:00AM slightly less.

Thanks for your recommendations and the technical details, this is great! When I speak to them, I will let them know.

I used the default ac/dc ratio (1.2). Below is the full output (from example.py). I just used this code as a basis, didn't explore any other functions. If you need more info, let me know and I can figure out the other functions: Site Name: My Home - Firmware: 22.18.3 21c0ad81 - DIN...
