Exactly. Maybe I'll try for a few more once the first 5 are installed and subsidy funds transferred.The government makes the rules, I just play by them to the best of my ability.

With a medical baseline you qualify for 2 powerwalls regardless of peak consumption. I failed to mention you have to have sustained multiple PSPS outages to qualify.Nice, I'm guessing you or your installer got your greenbutton data and it showed you using 25 kWh over a 60 minute period. That's how PG&E sizes your SGIP.
1x Powerwall 2 can export 5 kW. So, you would need 5x of them if your peak annual demand over 60 minuets was 25 kW (25 kWh measured in the Greenbutton).
If your 1 hour demand shows a need of 25 kW you might get another 2 under the large scale program with rebates within a year or after SGIP is satisfied.We are in Tier 2 HFTD & on Medical baseline. We had a panel upgrade to 400amp downgraded to 300amp main. Whole house backed up minus the electric double oven, outdoor spa & casita A/C. We replaced our (2) 5 ton A/C units with high efficiency ones (low LRA). We are on TOU-5p-8p and run on batteries during this peak time. Batteries can get down to 35% just in these 3 hours. We have 3 powerwalls with the sgip rebate already received. Problem is those don't last long in socal heat with AC running. Would we qualify for SGIP again to add 3 additional powerwalls?
Yep, a max of 5 is the sweet spot. Gets funnier above that so glad I stopped at 5, and save a bunch of money too.If your 1 hour demand shows a need of 25 kW you might get another 2 under the large scale program with rebates within a year or after SGIP is satisfied.
Once you go over 5 units the payback is slower, as it needs to be monitored and reported to your utility for 5 years. My understanding is that in those cases they pay out 50% of the incentive right away, and the other 50% over the next 5 years based on your actual discharge data. The company I work for would charge an additional fee for that 5 year monitoring, so the final cost to installed kWh ratio is slightly worse at 6 units than 5.
This understanding is based on PGE workings, so I cant promise your utility is the same.
Have you had 2 or more PSPS events? If you have you might qualify for 2 powerwalls under the medical baseline. To qualify for the 3 powerwalls under SGIP you would have to meet income limits and I believe be on a well pump as your sole source of water.We are in Tier 2 HFTD & on Medical baseline.

You are correct. I thought you had to have had events but with medical baseline you do not.there is no such PSPS requirement in so cal (at least not in SCE territory). i got two powerwalls via SCE SGIP, medical baseline, and have not had a single PSPS shutoff yet. i am in a tier 2 fire zone, but no PSPS.
AFAIK, at least for SCE, the requirement is that you're in a tier 2 or tier 3 fire zone...there is no such requirement that you have experienced any PSPS shutoffs.
We qualify for Equity Resiliency based on this matrix with several PSPS events and me on CPAP. However, we already have a solar roof and 2 Powerwalls. Can we get funding to add a 3rd Powerwall?The requirement is Tier 2/3 fire zone OR 2+ PSPS events, PLUS another eligibility factor such as med baseline or electric well.

Good question, I'm not really sure. I do know Equity Resiliency funding is currently waitlisted right now for all of the participating utilities, but I think there's more funding coming.We qualify for Equity Resiliency based on this matrix with several PSPS events and me on CPAP. However, we already have a solar roof and 2 Powerwalls. Can we get funding to add a 3rd Powerwall?
Yes, you will need to specify within your SGIP docs that you have a current system and are only adding one. The rest of the process mirrors normal sgip until PTO and you’ll likely have to reiterate some details to them.We qualify for Equity Resiliency based on this matrix with several PSPS events and me on CPAP.

We only qualify for the base SGIP rebate, but Tesla is telling me they are too busy to fill out the paperwork, so we can't get the rebate. Does anyone know if (or how) to self apply? Tesla claims the contractor (Tesla in my case) has to complete the paperwork and they don't have time (despite the fact I waited 1.5 years for my Tesla solar roof plus power wall).
One major point to SGIP upfront: you must obtain SGIP approval before installation begins.We only qualify for the base SGIP rebate, but Tesla is telling me they are too busy to fill out the paperwork, so we can't get the rebate.

Yeah, the SGIP set installer limits on the residential programs. The major players hit those limits really fast on the small scale programs.
A handful of people snuck around this and claimed self-developer status to avoid the caps.
I tried to go the “self developer” route on the large scale program … but I had to prove no licensed installer was part of my install.
Tesla still does SGIP, but only for larger scale community programs not available to homeowners.
I think ( but am not positive) that Tesla only does equity and resiliency SGIP filings. I dont think they did large scale (3+) SGIP filings that were not in that specific program previously. Thats what I was told when I looked into it when I was looking at powerwalls ("we dont do large scale filings, and we have hit the cap for small scale, which is 1-2 powerwalls. You can get waitlisted for that program, sir." )
Then I got 2 other bids on installation of 2 powerwalls, and found that the other bids were the same price as Teslas, roughly, but Teslas was "what you pay right now" and the others were "what your final cost is, after you get the SGIP rebate that we can not guarantee you get".
