Experience with CA SGIP?

Hopefully starting an install soon, and trying to get realistic expectations for CA SGIP. I'm planning 16.4kWh of battery, it looks like that would put me in the 'Large Scale >10kW' group rather than the 'Small Residential <10kW' group? And I don't qualify for any of the additional rebate groups (fire, low income, power shutoff, etc.).

1. Is it realistic that I might get the Large Scale $0.25/kW rebate?
2. Timeline? I found one resource that more funding is coming in July, I might be on a waitlist until then?
3. How difficult is the paperwork? Does the installer HAVE to do it, or could I do it on my own?
4. Installer is saying they need to charge me $650 to process the paperwork. I think this is because they use a third party to do it for them. Is this reasonable? Pushing back on it because they told me this after I had signed my contract.

Thanks

Is your power company accepting applications? I'm not sure of the limits for each class any more, but I thought for sure the large scale was significantly over 10kWh.

From the sound of it, you're in an area that must be in the first 50%, it doesn't look good:


Small scale residential:

It seems to be pretty clear about the 10 kW, just doesn't sound right since it's so low.



Trying to determine if I'm reading the capacity correctly, and it seems like it? So with 3 48v 100Ah/5kw batteries puts you over 10 kW..

Batteries are rated in kWh, inverters are rated in kW. I think there's more to it than just having a certain amount of storage.
It mentions divided by the duration of storage.
So if you can discharge your 15 kWh battery in one hour, that would be 15 kW per their math, at least if I'm reading it right.

What's the inverter you are installing?

Where can I find the document you pulled that screenshot from?

Agreed, another thing I find confusing. I'm installing a Sol-Ark 15K, with 11.84kW PV, so everything in my system is above '10 kW', and yes the 'discharge time' is something I'm not sure how they are calculating.

That is from the 'SGIP Handbook', can be found here: https://www.selfgenca.com/home/resources/

It's a 150 page document, clearly written by a team of bureaucrats and lawyers. But all the 'easy to read' resources I can find don't have any of these specific details at all.

Well I found a calculator, this helps understand what they are looking for.

The eFlex battery datasheet shows two continuous discharge rates, 'recommended' and 'peak (for 60 min)'. Using the higher of the two I get a 13kW system. Using the lower one I get an 8.6 kW system. So again that could sway the results depending how you interpret the question 'Maximum Continuous Battery Output'.

HELP. Has anyone successfully filled out the PGE-SGIP form. I would like to hire someone to help my contractor complete the form
Please contact me here. Thanks. Karen in Santa Cruz
