Hello,

We have solar and two Powerwall 2 batteries. When we have an outage, our power consumption is throttled to .6. kW. That’s fine but in an outage during summer, sometimes we do want to run our a/c for a little bit just to cool our house down, then shut the a/c off to conserve power. Any way to adjust this setting?

Hey all, I got a quote for an 8.8kw system with a PW3 and expansion pack in the Bay Area, CA and keep going back and forth on whether to purchase the system with a loan (~$40,000) or leasing the system until the buyout after five years. The buyout is capped at $24,950 or FMV, whichever is less.

The difference between lease and purchase is not very much overall and the lease would free up some capital to do some other home improvement projects. Are there additional taxes or fees associated with the buyout after five years? Does anyone have any strong opinions either way or any horror stories one way or the other?

Hi fellow MA Battery Energy Storage System (BESS) users.
I don't have a Tesla system but reading through here I deduct that you guys get a notification when an event is triggered by National Grid.

I have a SolArk system and we don't get any notifications, not a "heads up", not a "it's happening", not even a "this is what happened" notification. CRICKETS!!!!

Can one / some of you be so generous as to post here when you get these events?

It would help greatly in being able to "verify" the payout we get at the end of the year, so far, NOBODY PROVIDES ANY REPORTS for that, neither National Grid nor SolArk (in my case as a SolArk user).

Thank you!!!

A funny thing happened on June 10, 2026. My Tesla app started showing zero exports to the grid whereas before that I always had exports going to the grid once the powerwall batteries were fully charged (solar goes to charge the batteries until full, then excess to the grid). I also noticed that my reported Home Kw Use nearly doubled from what it is normally every day once the batteries got full, and the Home Use curve was mimicking the Solar Generation Curve.

After a month of troubleshooting with Tesla Support, turns out a glitch got into my system somehow on June 10 that caused this error in the App data reporting. Fortunately, the electrical company still received the correct amount of Grid Exports to give me credits as they do not rely on the Tesla data but on the meter itself.

So exported energy was being incorrectly allocated to Home usage rather than Grid export. While the Powerwalls were charging, all energy flows were normal. On July 19, Tesla pushed Gateway firmware 26.10.3 (build 4f924de8) into my system which fixed the problem. After the update, Grid Export and Home energy accounting returned to normal.

Is there any way to export my power from battery to grid during high peak rates at night ?? Thanks in advance. Rick. If so, how ?? Right now it only exports my solar power to grid. When the sun goes down, I still have high peak rates that I could sell back to Ameren.

I have a Tesla Powerwall 3 and solar panels and wanted to know if there’s a way to get Amazon Alexa to automatically announce when the utility/grid power goes out and the Powerwall switches to backup power and
when power is restored and the house switches back.

I’m open to using Home Assistant, IFTTT, Alexa routines, or any other reliable solution. Ideally, I’d like an audible announcement on my Echo devices, not just a phone notification. Has anyone here set this up successfully? If so, what hardware/software are you using, and how reliable has it been? Any guides or examples would be greatly appreciated.

Question. I’m installing a system with 4 powerwall 3’s and 2 expansions. Problem is powerwalls and inverter because they’re as one unit are going to be about a 1000’ away from the solar via a trench. Everything I’m seeing says the mcis can’t be further than 525’ and that’s for a round trip, so half that really. Any ideas on how to make this work?
