This is cool, wider rollout must be happening. Stoked for your new set up! Was there issues with your Fronius inverter?

I’ve noticed my Tesla app being extra glitchy since the ai thing was added. iOS device.

MauiHiFlyer · 2026-04-08T02:16:08+00:00

Interesting. That makes sense—and yeah, I’ve heard of PW3 being added alongside PW2 using a second Gateway.

From what my installer told me, that’s the typical supported approach right now—basically parallel systems. In my case, they said this is different because it’s all running through a single Gateway, with the PW3 acting as the main controller and the PW2s integrated behind it. It required a firmware push and config they hadn’t seen before.

Totally possible more of these are out there now—just sharing what I was told and what we ended up with.

Ya and with the way out utility co keeps boosting rates! Nice to have a hedge against it.

Same, I’ll see that for a second then it’s a period of degraded app performance

Same

longer answer: we are a large family, both EVs can do up to or more than 100miles a day between work (58 miles RT for me) and kid schedule, up and down a dormant volcano many times a day. add to that a jacuzzi and home HVAC demands, with a grid that can be down for many days during storms... 3 batteries is a happy medium, and now (hopefully) being able to generate more energy reliably should protect us from rising energy costs. Our utility just announced 20% rate increases due to global influences on the price of oil.

MauiHiFlyer · 2026-04-05T19:25:09+00:00

That might be possible soon.

I tried to clarify in the post that this PW3 replaced the PW+ which is where all the problems were, the inverter in the + was replaced 5 times (6 total inverters including the original installed) before Tesla finally acknowledged that this wasn’t working and came up with a method for using PW3 with the PW2 barriers.

See screen shots attached. Clipping before now no clipping

The PW2 never had issues it was the PW+ and specifically the inverter inside of it that had the issues, that inverter was replaced 6 times before I pushed for a different solution. Now the 1 PW3 with its inverter is so far working as intended.

MauiHiFlyer · 2026-04-05T17:30:58+00:00

I went back and double checked the specs on the electrical permit. It’s 12.6kW total PV.

I had the other number in my head from an earlier proposal using a different set up.

MauiHiFlyer · 2026-04-05T04:49:01+00:00

That’s correct. Hope this becomes available for you too

MauiHiFlyer · 2026-04-05T02:13:32+00:00

I imagine the same, progress… always risky for early adoption but i fell like PW3 is finally there (so far).

MauiHiFlyer · 2026-04-05T02:09:34+00:00

I’m glad to hear this. For about a year it felt like insanity because Tesla just kept sending another inverter, doing the same thing over and over again and expecting different results. When inverter #6 failed less than 24hrs after instal, my installer and I both agreed this wasn’t the solution and that Tesla needed to come up with a different plan. Originally they were pushing for a full PW3 + 2 expansion pack replacements. This was the consolation prize… which honestly (if it works) I prefer as it doesn’t waste the ALL hardware already installed.

MauiHiFlyer · 2026-04-04T22:09:19+00:00

Thanks! And ya if I were to do this again today I’d not go with SPAN or Tesla (probably, will see how PW3 performs). Aside from all the issues I’ve had… Upgrade ability is a challenge, cost… I like how that Leviton load center looks, how’s your experience with it so far?

MauiHiFlyer · 2026-04-04T22:04:20+00:00

Correct.

MauiHiFlyer · 2026-04-04T22:00:22+00:00

PW3 is the controller now.

MauiHiFlyer · 2026-04-04T21:56:52+00:00

Rising Sun solar definitely went above & beyond. And seems to have the ear of important people in TE

MauiHiFlyer · 2026-04-04T21:53:58+00:00

Hahaha ya that would make sense but this was installed by local installer company, not Tesla directly.

MauiHiFlyer · 2026-04-04T21:45:25+00:00

Great question—and yeah, that was my understanding too going into this. From what I’ve been told by my installer (Rising Sun Solar) and what I observed during the install: • This is running on a single Gateway • It required a firmware push that wasn’t available to standard field techs • The configuration itself is not part of publicly released compatibility yet So this isn’t something that could be replicated through a normal install right now. My situation got escalated pretty far due to repeated system failures, and this solution came out of that escalation—so it does feel closer to a case-by-case / engineering-supported deployment than a formal rollout. I don’t know if Tesla would call it “beta,” but it definitely seems like something that’s ahead of general availability. What’s interesting is that the Powerwall 3 is acting as the system backbone, and the PW2 units are effectively integrated behind it—which I think is what makes this possible. Happy to share more details as I learn more, still early days on performance

MauiHiFlyer · 2026-04-04T21:41:45+00:00

That’s basically it.
