Thank you, miimura. I sent a message to PG&E and got reply two days later. Its response is exact what you said.

Issue was finally resolved. I called tesla support for the issue of low power output. An agent responded and told me immediately the low performance was abnormal. She scheduled a technician visit a week later. The technician tried split the first string on inverter and found splitting does not...

Thanks to everyone for helping. I'll call PG&E to fix the problem. BGbreeder, $2.47 is average daily cost after PTO. It was $1.92 prior to PTO. There is an increase in daily cost, while the chart showing negative daily cost after PTO. I read the bill carefully, and realized that no...

I saw my first PG&E bill after PTO on my PGE web account. I am shocked to see electricity bill going up after PTO. Monthly electricity charge (3rd party electricity excluded) is $79 and it was $57 prior to PTO. However, daily electricity usages are negative since PTO, but I am still got charged...

Thank you, Bitslizer. I'll check fan during the day. If it is not running I'll contact Tesla to fix it.

Thank you for your analysis. I did check firmware update in Installer mode and it says no update available. My software version is 20.51.2 while all others have 21.xx.x . I did hear liquid noise in my inverter occasionally. However, I don't think the inverter is over-heating. It is outdoor on a...

Add two pictures. Pic21: current working configuration - W1 in string 1, W2 in string 4 with 3/4 jumpered. Working great yesterday without reset. Best performance so far, but possibly limited by W1 due to 13A reached. Pic22: Both W1 and W2 parallel - W1 in string 2 with 1/2 jumpered, W2 in...

Before stating what have been done, I want be sure safety first while working during day time with plenty of sunlight. I switched off the disconnect to grid so that system power is off. I carefully measured voltages and currents from solar panel wires. To my surprise, all wire voltages are zero...

After testing many times in different wiring configurations, I found out how to connect my system for better output. But Tesla system is quite complex and it's not easy to figure out. I first wired according to Bitslizer's suggestion during night time without sunlight at all. It worked the next...

Reading your posts helps me a lot. If wires connected according to your suggestion, web portal should show string 1 empty, string 2 single, string 3 and 4 are parallel with the same vol/amp. If jumper 1 and 2, and wires connected to 2 (bottom row) and 3 (top row), web portal will show string 1...

Make sense. Thank you! I was wondering why the two strings wired into the same mppt by the installer. Also, do you think that power output from parallel 2x9 panels is limited by mppt? 2x9x340w x 85% = 5.2kw, but each mppt can handle 3.8kw only

Everyone else is trying to fix inverter daily reboot issue, but I have to do manually daily reboot in order to get better power output. Odd? I spent some time to investigate my system. See attached pictures. I have 24 panels of 340w but do not know how they are wired. There are two strings...

I have 24 panels placed to two levels. 6 are on top level and others are on lower level. All panels have the same orientation towards southwest. I am not sure how the panels are connected, but the two strings do not show even output. At the moment when I logged into inverter web page two days...

I can access inverter with wifi. There are two strings. One shows ~2x amperages than the other. I don't think one string was disconnected due to importance of both strings. I cannot compare amperage before and after reboot since inverter webpage does not allow login before rebooting. So, it's...

It happened again today: rebooting inverter increases production. I was not at home until 4pm when I found power production was only ~4.1kw. I immediately power cycled inverter and production went up. So I must do daily inverter reboot to keep high power production. This must be a firmware bug...

Inverter issue: I have tesla solar panel installed without powerwall. The system was activated two days ago and I connected it to the internet ~11:00 am yesterday. My panel produced ~5.2kw at peak time throughout yesterday as shown in picture 1. This morning the panel generated ~4.2kw only under...
