Yes, you will change your W-Fi connection in the Tesla app, under Settings -> Wi-Fi.

Sorry to hear that, but even so, 28 days is a great run! Hopefully it doesn't end with zombies :) The screenshots are from Powerwall Dashboard: https://github.com/jasonacox/Powerwall-Dashboard

Following up on this, probably the best month so far. 30 days and no pulling from grid other than sync. Even looks great going back 90 days to February...

My ROI on batteries is about 9.5 years at current electric rates (after federal tax incentives, and after solar ROI is reached @ 5 years 7 months). My utility has raised rates twice since I installed, so I can only assume that timeframe will reduce over time. That's just about at warranty...

I drew power from the grid on April 4th, haven't touched it since. Well, other than grid sync. The graph below shows my set of powerwalls charge rate (reserve set to 20%) - April 1st to today. Here's my import vs export graph. This is a cumulative graph - blue line is export and purple...

Yes! My install completed on Aug 31, 2022, received PTO on Jan 17, 2023. Ran for about five months before I had to make a payment.

I have a 20.4kW Tesla system, 51 T400 panels with two 7.6kW inverters. My max daily production (to date) was 137kWh.

Adding more data. Not trying to decipher specific reasons, just think it is an interesting exercise in looking at variables. Wind speed was pretty close on each day. Wind direction was slightly different... I bet that is a key factor.

Yes, there were some clouds at the tail end of April 14th, around 6:45pm. Around then I am typically down to 2.1kW production. It probably impacted slightly. I actually seem to have had more high clouds on the highest production day, April 13th, throughout most of the afternoon.

This is more of a dissertation than a question. I had three perfect, consecutive sunny days, April 13th through April 15th. I know temperature affects solar output, but what about humidity and barometric pressure? The production variations are not very big, less than 5%, but I expected them...

Yeah, don't think an inverter would run consistently at 165% production. The 7.6kW inverters barely do 125%. Plus, unless you have giant magnifying lenses pointed at your panels, not likely that 4.8kW of panels will produce 6.1kW.

From my experience, this is normal. My reserve is set at 20%, and on those times I reach that threshold (sometime in the middle of the night usually), by morning the PWs are down to 18 or 17%.

Amazing accomplishment! Next up? Cancelling Comcast/Xfinity? That'd put you 2/0 into superhero status! That is a long time to go with issues, I can understand the frustration. Glad you got it sorted, and thank you for sharing your experience and resolution. It will definitely help someone...

When you hear Tesla saying 'it's coming soon', just think... Cybertuck.

There are bypass diodes in each panel to reduce this. When researching this last year, I found this video helpful:
