SGIP or course does not say for 2 you do a max test. You send them in 12 months of green button data, and they just look for the max 1 hour
use. If it is more than batteries requested, (which is only needed for over 2), then its a non issue. But if more, like I and others had, we had to provide data we used that much. Totally fair IMO.

So, you are not on medical baseline in your house? If so, you can keep E-tou-c

No idea on 3

4, well, man, what are they hoping to find?

I was on medical baseline E-1, but was hoping to stay on E-TOU-C since I don't actually have an EV, and I cannot grid charge my Powerwalls through any normal means.


Actually this is happening to something like 10% of customers, and everyone who dares to question the mighty utility lol. It used to be triggered every NGOM, but I think you never had this requirement? Can't quite remember if you bought yours when they still required this or afterwards.

No, I think Powerwalls were finally classified as revenue grade PV metering devices, and the NGOM requirement was removed. I still think it's weird the Tesla PV generation reporting is about 4% higher than Enphase's reporting. I would have assumed Enphase artificially jacked up their own production readings to help convince people they were making lots of suds.

you can stay on tou-c if you are on medical baseline

For customers with large PV production, it's my understanding that EV2-A is slightly better very often compared with ETOU-C especially when you can actually turn your grid usage to 0 during the peak times. Off peak is quite a bit cheaper. Comparing rates isn't my specialty but my personal system is planned to move over to EV2-A.

Thanks for those inputs!!! Now, might see soon if the installers can get approval to make my system, even though lots of north facing panels, approved to be very large, like ending up being 25 to 30KW.

I don't understand... the guy that showed up at my house has literally taken the same pictures the previous guy did; and the guy before that did.

They use their camera phone to snap photos of the batteries, disconnects (yay), sub panels, TEG2, conduit, and that fancy site placard that makes no sense. They don't touch anything or pull any dead-front panels off to inspect anything.

I thought at least the guy today would pull on the disconnects to test the system or request evidence the batteries are able to power home loads. But nope, just need more pictures. I asked the guy what his work order said to get some context on whether he understood what purpose he was out here for since people keep getting sent out here to take the same photos of the same batteries and same panels. He said his work order didn't say why he was here, it just instructed him what to do.

But he said he understood the reason he usually gets dispatched to homes is because SGIP applications from "new" installers typically require photos to prove the installer is actually installing equipment. SGIP doesn't want an outfit just submitting bogus SGIP claims, hoping to collect money without actually doing anything.

I told him that I used Sunrun; not some new local shop that has never submitted an SGIP before. The permits are submitted by Sunrun, and SGIP would easily know this if they searched the permit data with the County. Sunrun and Tesla have been submitting SGIP applications for LG and Tesla battery installations for years. He said "hmmm that's weird" and left.

So yeah, at least this is just at the level of weird inconvenience instead of some project-halting BS. Still hyper annoying and I wonder why they keep needing to do this. Like no wonder PG&E has a tough time making a "fair profit"... they literally pay people to just go around taking pictures after someone else has taken pictures. And some homeowners willingly delay doing the laundry until midnight to compensate for PG&E being PG&E.

I still need to produce that 15 minute interval data though. Everything about PV and ESS is super duper weird.

@holeydonut With all of your issues you had with your install just imagine what it would have been like if you were in Palo Alto.

Spoiler Alert, they love disconnects also.

Yeah, I'm lucky Contra Costa has Garth Robertshaw; and not Rhonda Parkhurst. I'm 99% sure my install would have died in PA. But Contra Costa actually helped me figure stuff out. It was actually Sunrun and PG&E that made me put on all the disconnects. The County guys thought the system didn't need them.


But... oh wow, the Cobalt CEO went on the record to actually put an ounce of criticism? This does not bode well for Cobalt to continue doing work in Palo Alto. Rip.

But other times personalities get in the way, and it seems to take on a life of its own, and becomes a power play or an adversarial situation," he said

You know it's funny, I've heard that Rhonda does this to every install in PA. I thought it was a joke, but it really isn't.

In recent interviews, Coale was one of several contractors who singled out inspector Rhonda Parkhurst, a national expert in electric systems whose passion for imposing requirements that don't exist anywhere else has helped drive contractors out of the city. Some inspectors, Coale said, won't leave a job unless they find something wrong and make you fix it. Parkhurst, he said, seems to go out of her way to make things difficult for solar installers. (Several other contractors echoed that assessment.)

"The torque test that they do on mechanical and electrical systems — no other jurisdiction does that. And if you have Rhonda as an inspector, she'll point at the most difficult panel to reach 100% of the time," Coale said.
