This is great news! I had 3 Powerwalls installed in February and it would be awesome if I could get the SGIP rebate. I downloaded the Developer Eligibility Application from this page SGIP | Developer Registration Is that what you are talking about? What boxes did you check in section 2)...

I wish we had more control. What I really want is to charge the Powerwall to 100% using solar during off peak and part peak, and discharge more than my home usage to the grid during peak, down to 25% or so unless there's a storm brewing. In other words CPUC "no grid charging" mode. Since I am...

I just got my Powerwalls in February. I'm on 1.44.4 and Advanced Cost Saving mode. I'm on EV-A with peak, partial-peak, and off peak. In the morning (off peak and partial peak) the Powerwalls charge from solar until they are 100% full. Then they discharge during peak to zero out the load from my...

UPDATE: I got my December bill and I'm still on EV-A. The web site shows I'm on EV-2A but the bill is what matters :)

It was the Las Vegas office. No idea if that is official. I already have solar so my order is just for adding 3 Powerwalls with whole house backup.

Wow, I read your post and checked my account -- same thing. I called and got my install scheduled for April 27th, 2020! I should have checked earlier!

Why not buy one additional Powerwall from Tesla, and have Tesla install both of them while they are at it? It will probably cost less than $10,000 and you'll have two instead of one.

I signed off on my order in for 3 Powerwalls on 11/4, permit issued 12/3. I just got off the phone with Tesla, they said they will lower the price to make up for the reduced tax credit for my order and others placed before 11/30. I have no install date yet, but hopefully soon.

I also live in Cupertino and I'm waiting for my Powerwalls to be installed. I first put in the order October 15, and they said they submitted for permits November 8. How long did your project take?

I have Powerwalls on order, so I can't try this yet, but this web site says via the api - which is exactly what we want. hackerschoice/thc-tesla-powerwall2-hack

I just got a reply from Tesla about an NGOM for my Powerwall order, see below. They are still working it out for customers in the PG&E service area. They offered to do the install without the NGOM but that could delay the interconnection into 2020, so I decided to get the NGOM which does add...

I got a bid from Tesla Solar in August, the initial design specified Hanwha QCell panels and Delta inverter. I said I wanted Panasonic panels and SolarEdge inverter, and they were willing to do that at no additional cost. They switched to 315 watt Panasonic panels. In the end I decided to buy...

Per CPUC Decision 19-01-030 the NGOM is no longer required for systems > 10 kW, as mentioned in this article: CPUC Approves Energy Storage Net Metering

Yes, that sounds like a good feature request. We were discussing that on another thread recently: In other words, if you charge from the grid, NEM / CPUC says you can't export that energy to the grid, so you can't do rate arbitrage with storage alone. But you are allowed use that stored energy...

It's a heat pump so you need to divide the kWh by the COP of the heat pump, which can be found on the heat pump data sheet. It's typically around 2.2-4.4 depending on the model and the outside temperature. Since you are upgrading your electrical panel, get 225A instead of 200A, the additional...
