I too have the GW v2 connected via wifi, and I'm still on 21.20 (no downgrade).

Check your conversations, I just sent you a message with the info.

I'm also in DFW. I ordered a system with four batteries through a third-party installer. I had the first two installed in April 2021 and am scheduled to receive the remaining two in August (fingers crossed). My first two batteries were also manufactured around November 2020 and are the...

I have an almost identical setup in Collin County, but with 365W panels. My peak daily production this week was about 11% lower than my peak production in May.

I'm also on 20.40.3. Funny thing is that the installer wizard says my firmware is up to date, even after I click a button to check for the latest version, even though I'm a couple versions behind.

But can't the Powerwall draw power from the grid during Storm Watch? If so, wouldn't the Powerwall be a load at least some of the time? The issue is my installer is claiming the Powerwalls have to be included in the load calculation. If that's not correct, I'd like to point him to something...

Thanks everyone for all your help! I thought I had made good progress with my installer with all the suggestions offered here, until we got to the load calculations. First, one question about the optional load calculations for additional loads. Am I right that there is either a mistake or a...

Your logic is flawless and had me convinced I indeed had 2/0 aluminum. But no, 2/0 copper it is. The two disconnects are Eaton ECB225R with 150A breakers in them. The meter panel is Eaton but has no labels on the outside hinting as of the model (and it is also locked). All of this makes me...

Good point, I hadn't thought about that. I estimate the communications cable will have to be about 130ft long, taking into account vertical drops, curves will take in the attic, etc. It may get close but it's unlikely to exceed 150ft. The two sets of conductors between the 150A breakers and...

The complexity here comes from the fact that the meter and two existing 150A breakers are on one side of the house while the two 225A load panels, Powerwalls, and inverter terminations are in the garage on the opposite side of the house. We're in Texas where houses are large, so "opposite side"...

Thanks, Wayne, I really appreciate you taking a look!!! My inverters do add up to 66.5A but I am also under 2020 NEC. I would have no problem configuring the Gateway to export no more than 160A, especially since I am not under a time-of-use electric plan and therefore do not ever benefit from...

Congrats! Were they able to source enough Powerwalls for your install? SunPower quoted me two Powerwalls, but I've seen others state SunPower was only willing to allocate one to their install.

Here is a makeshift diagram of what I described above.

I obtained quotes from Tesla, SunPower, and various local providers. SunPower's quote was the highest at $3.46/W, compared to $2.01 from Tesla (other local providers were somewhere in between). SunPower offered me an additional discount if I paid in cash (no loan) which brought their price...

Howdy! I'm having solar panels and Powerwalls installed. My installer thinks I'll need two gateways, whereas I think I don't. I need your help! Here's what I have today: One 200A meter, housed in a 320A meter base, which feeds two 150A breakers, each protecting one of two 225A load panels...
