Since Elon moved headquarters from California it’s been like watching Palpantine reveal his true Sith nature and appearance. I’d say the insignia ‘T’ stands for ‘Texas’ now. Last I heard you could only get new PW in conjunction with installation of Tesla PV. I wonder if that will continue...

Unfortunately I doubt Tesla is putting any resources into generator / battery integration. They won’t even sell a Powerwall by itself anymore - only in conjunction with purchase of their PV solar systems. I was lucky to get my PW before the change. I’d suggest looking into Enphase batteries...

I’m VERY relieved to find that this problem hasn’t been seen on PW2 that don’t have PV. I was not looking forward to getting a UPS big enough to cover my 44U server rack (cause I thought the PW2 served that function).

Well, it appears that Musk has shown his true colors - just another fxxxxxx egocentric billionaire. Who else would move to perhaps the most regressive state at its peak of egregious activity except to avoid personal taxes and governmental oversight? I have a Powerwall II. It is now the last bit...

The shine must be off the reality of moving to Texas these days. New meme - ‘Texas plumber’.

From what I’ve been reading about what electronics require, the generator’s Total Harmonic Distortion (THD) rating will probably have to be 5% or less. Conventional portable generators are typically rated “less than 23%”. Inverter generators are closer to the 5% value. But the question is...

If you do your own work under permit and have it inspected and signed off, you’re much more likely to have it accepted by an installer. But you’d still want to arrange this with the installer in advance.

Check out the thread PowerWall 2 Interface with a Generator

That explains a lot!

WOW! An actual Tesla design for off-grid PV with generator! Congratulations! I have a PW without PV so I’m going to have to study this to see if it would still apply (and if I’d need a second PW). But I would think that an on grid system that had a transfer switch at the service entrance would...

I see most of the replies were posted Wednesday. It is now Saturday and heat records were broken today. Triple-digit temperatures in Southern California heat wave break records | KTLA There are also Public Safety Power Shutoff (PSPS) all over Southern California tonight. I have a Powerwall and...

Are they both wired under the same Gateway to charge from PV?

Here’s a twist on that question. Can you ‘nest’ one Powerwall and Gateway within another Powerwall and Gateway? I have a Powerwall and Gateway set to charge from the grid during off-peak (8 am to 4 pm when solar PV excess can be a regional problem) and then power critical house loads on-peak (4...

I think you’ll see a big push for heat pump water heaters in California starting next year. The state sees them as a way to reduce carbon fuel use, as well as a way to soak up the surplus solar PV during the day by setting when they preheat water. Discussion currently of adding them to the SGIP...

Whatever solution you go with, be sure it screens blowing sparks from entering the house structure. Fire miles away can spread when the winds are right.

The low hanging fruit usually includes more attic insulation, sealing duct leaks, duct insulation, and sealing window leaks. In a warm climate like Florida you could also use a heat pump water heater to get some cooling benefits (pull incoming air from outside, the outgoing air is cool and can...

As an alternative, I’d suggest getting everything short of the actual Tesla equipment installation preconfigured yourself under permit (any required service upgrades/wiring, designated locations for Gateway and Powerwall, junction box with service loop for Tesla connection, roomy conduit, etc)...

Generator input, charging the battery? That’s the feature I’d like to see added to the Powerwall. Enphase says they’re going to have future generator compatibility in their new system (but will it include charging?).

Thank you, that’s very helpful!

I also prepped my electrical upgrades so the PW could go in with a minimum of additional wiring. This was without PV, grid charge only. The main things were (1) identifying where the components would go and (2) having a junction box preinstalled with a generous service loop of wire for the Tesla...

I had my Powerwall installed in January and Tesla is still processing the paperwork with Southern California Edison. I’m not in a fire area so I haven’t followed the status of funds for that purpose.

My understanding of California’s SGIP program and the federal tax credit is that for SGIP the Powerwall can ONLY be charged from the grid, while for fed tax credit the Powerwall MUST be charged from solar. There is so much solar generated in California that daytime is now off-peak and SGIP has...

I’m in California. Here the state has a partial rebate if the Powerwall charges ONLY from the grid. (Self Generation Incentive Program - SGIP). We also have Time of Use (TOU) electric rates. So I’m able to charge off-peak (daytime until 1600, thanks to all the solar pv) and discharge on-peak...

I do because I wanted to use my PW for load shifting (charging from the grid Off-Peak, discharging On-Peak). To get the federal tax credit you can only charge from PV. By not charging from PV I’m also eligible for a rebate from California’s SGIP program (confirmed and I’m waiting on the check)...

Given your situation, I’d agree with pouring a concrete foundation so the curb doesn’t interfere with the dual PW install and then doing a floor mount against the wall. This will give you about 4 inches of clearance from the floor in case of water or mud intrusion. You also might be able to have...

I agree with all the “power during a blackout” comments, which in my mind is itself a conclusive argument for a Powerwall. Operating it so that it helps shave down its own cost is icing on the cake. If you’re on a Time Of Use billing plan where the peak rate is more than 10% of off-peak...

Yep, that’s my dream confirmation too. Currently I’m completing the pre-Powerwall electrical upgrades. I wanted a copper bus so staying with a meter-combo wasn’t an option - I couldn’t find a EUSERC compliant one that wasn’t aluminum. So I decided to get a commercial grade 200 amp meter...
