It would sure be cool if Powerwalls supported at “charge on solar”-esque setting where we could set the maximum SOC (or maybe that’s just 100%) under all sources of charge, and a lower SOC for Grid Charging. Especially for those of us in PGE land, the GC+EE can really start to add up the...

April Fools…

I never really debugged this much. Two days after this Tesla replaced one of my four powerwalls and everything started working again.

I will have a good data set to work of after this June (1st PGE true up but I think my SJCE true up doesn’t actually happen for an entire additional year after that per their “10 bill/month policy”. My NBC’s will dominate this year because of running TBC+GC+EE with 4 powerwalls. My NBC is ~=...

The slam-shut exception is apparently not listed in the Greenbook according to my PG&E contact... “it's in an internal document we have and on there it does say that the acceptable minimum clearance distance for the slam shot regulator is 12 inches radially and any direction from the vent...

I’m aware of the hidden location. It’s not there. There is some thinking that actually going forward, there will be no more B&W bill, people will just be moved to the “new” Blue bill movinng forward. When was your PTO date? We have yet to see a person with PTO after May 2023 that has moved...

Has anyone that got PTO in 2023 ever seen the B&W Bill? Or is that not a thing anymore? I got PTO in June 2023, and I still can’t get the B&W bill. I get the “new” Blue bill…which has the much nicer YTD charges for true-up (not a forecast), and better details of NEM chargers, MDC, NBC, etc...

has anyone had issues with the Tesla app displaying Powerwall data? Home, grid and car are all showing data. And the Powerwall is showing SoC. But not energy flows in and out.

Not quite yet. Still need to trench a bit, lay the pad and then get the back to finish the cables.

Ok, so I guess the sub panel part would have been in theory ok….but your tap would have need to have been 5x60A=300A, right? Or you could just set the EMS to have a max of 160A (160A @ 125% for EVSE = 200A). But that doesn’t appear to be approved for CA until they update to the 2023 NEC code...

Do all 5 of your wall connectors have dedicated/separate branch circuits? Or are any of the 5 EVSE sharing a circuit? What AHJ are you in?

Yes, re-reading the SJ website you are correct, it’s just limiting the level of EVSE, not the qty. great! As for the multiple EVSE’s sharing a branch circuit…this is what I was referred to by SJ folks. … In doing a little research it looks like the NEC did amend for the NEC 2023 code...

Thx for the data point. While maybe not applying to SJ AHJ, I guess that’s promising…everyone says Santa Clara County AHJ is the most extreme! I found the reference to limiting 2 EVSE for level 1 or level 2…Electric Vehicle Charging Stations | City of San José Actually, my understanding in...

Looking for advice from anyone that’s done a standalone pedestal install! 1) How deep does the concrete pad need to go? 2) How wide? 3) Did you go with a) a rectangular form to perfectly match the base of the pedestal (9.75”x7”), b) a larger rectangular form then the pedestal base or c) a...

I have definitely had the 100-200kW instantaneous car spikes in my data for the last 3mo. I’d say 3-4 times per week. Typically happens between 1a-5a, but id say 80% of the time it’s a ~150kW spike between 1a-2a. One time it showed 500kW spike! App is the latest 4.28.2-2157 - 4af549164e All...

Time to redo the GC/EE spreadsheet, sigh… But I suspect as a net importer…as long as the arbitrage is > then the NBC’s (not taking into account wear on PowerWalls) then GC+EE is in my favor. The spread went from 0.31250 & 0.18539 (summer / winter 2023) previously to 0.31051 & 0.18540 (summer /...

Not sure how i can differentiate between those terms. Not charging, not discharging, doesn’t show registered in GW2…. They says they are going to roll me back to 23.28.2, but so far that hasn’t happened.

Anyone have any idea when the checks get mailed for 2023 calendar VPP events? Is there any way to get the data from your contribution? Or you only get the check / $ amount?

As far as I can tell, yeah. Running deficit right now, but spring sun will catch up. We’ll still remain a net importer of power (3x EV, will add 2nd AC, etc), but hopefully close to break even on $ credits. But in the end it will be NBC’s that I think will dominate. NBC’s are somewhat...

At least the FW didn’t brick one of your PW’s like it did to me the last two times… Actually, just checked…seems between 2a-4a this Friday Tesla pushed me from 23.28.2 to Version 23.36.3 aa269d35… …And it appears to have bricked one of my four PW’s again, for the third straight time!

4.28 is needed to show multiple wall connectors. 3rd might take a bit…my electrician has been ghosting me for like 2mo’s…

Correct. I prob didn’t need to GC/EE as much, so can raise the reserve %. Will have added benefit (beyond reducing NBC’s) of wearing the PW’s less, and keeping me a bit more protected for the PW warranty. I’m still trying to get a feel for how much i will catch up in late spring as I close in...

That’s what 3x EV and 4x PW (with 0% reserve, GC & EE turned on) will do to you. I’m still trying to dial-in the some of the aspects of PW with custom rates. And based on how my first year of NEM2 goes, I’ll probably increase my reserve to >0% so I can lower the NBC’s next year. Still haven’t...

with the latest version of the app, it’s pretty cool how it shows this. I’m installing a 3rd wall connector and wondering if it will show that too? Screen is starting to run out of real estate. Have not tried deleting anything yet…heard people could not do that. I’m sure over time they will...

I agree, I don’t believe there is any forecasting. It’s just a running cumulative YTD total it would seem. If your NEMC > NBC + PCIA - MDC…then it will show your NEMC. Conversely, if your NBC + PCIA - MDC > NEMC, it will show your NBC + PCIA - NEMC (this is the case for me so far). As...

It feels like true-up “estimate” is a bit misleading though. It’s more like a cumulative sum of your true up cost through the date of the bill. So as you note, it will gradually make people more and more aware of their true up over the course of the year, and the closer you get to true up date...

This makes a lot of sense. Need to make sure that in a grid outage event that the care going V2G doesn’t keep power flowing…I believe called anti-islanding. Can be really dangerous / deadly to line workers. The powerwall/gateway have this technology. And the powerwall appears to be able to...

Curios, @dho112 when did you get your PTO? Was it recent? Or a while ago…as you seem to be getting B&W bill. Also, on your Blue bill…is it the newer blue bill format (BB2) like @holeydonut and I? Does it have all the cumulative NEM graphs and such? Or is it the same blue bill that has...

Very weirdly…since this post, my Powerwall has stopped GC to 99-100% SoC each night…and instead only goes up to 83-86% SoC for the last few days. So Tesla Energy R&D team that is watching this thread… hi 👋, thank you, and if you could tune it a bit more to get my to only 75% via grid charging...

Do you have the link for the approved NEM2 document?

It’s on the CPUC website?!?! https://www.cpuc.ca.gov/industries-and-topics/electrical-energy/demand-side-management/customer-generation

I feel like i literally got to re-learn my entire EE degree going through the install process. I'm generally interested in this stuff, so it was fun and valuable to know it inside and out as you say. But geez, as OP points out, there's way to much effort required to get things right...and too...

I had similar during my install, they forced a few strings that should have been separate to go parallel on same MPPT. I pushed back hard, they said nothing they could do (material cost savings...and "it wont impact your production at all"). I stood my ground, asked them (nicely) to escalate...

I've had similar crazy spikes a handful of times (like 5 or so) since starting to use CoS. It seems also sometimes I click on the car, and no data is there, and then a few min later i click on it (have not touched car, removed cable or anything) and the "red" data is back. Maybe car goes to...

Yes, if I raised my backup reserve to 50% (from 0% today) then I would reduce my EE exports by 50% each day, at 4p peak it would only export 54*50%=27kWh (plus anything that went straight for PV to grid, which might go up if there is no ESS to fill and the cars charge to their limit) instead of...

My strategy is not quite this. Close, but still different. Aim is to maximize NEM credits which is up to max 4x PW (54kWh/day, with 0% reserve) and then adding any PV between 3p-9p (very little in winter). PV from 9p-3p should first go to PW/ESS (this is not working great at the moment), and...

I have both GC & EE. The purpose being to maximize NEM credits to offset the fact that I am a significant net importer (3EV's).

Well, I definitely don’t have a bill yet that is indicating my limits…so it’s kind of hard to tell if I’m over, close or not. This is why the Charge On Solar (CoS) is pretty important. It allows me to have have all daytime production prior to 3p go to the car, instead of the grid. However, it...

Hmmm. I think this is an issue, because as we get into winter my ratio goes way up. Actually, might depend on one key thing (I think I asked this before and someone likely answered but i forgot)…is monthly export limit an actual export limit (one way) or is it net export/generation? Below you...

Imported power in kWh is there by billing period, but not by calendar month, nor by 5/15min interval (didn’t even know they did that for NBC). The bill accounts for tariff changes (or in below case the summer/winter switch). That’s where I really came to understand the negative impact the...

Might have go clear a cache in Chrome. I thought I saw they recommended that somewhere.

Yes, the BB2 has all this. The only thing it does not seem to have is your maximum allowed exports in kWh for each month of the year.

I actually think the new blue bill (aka BB2 for short 😉) is pretty easy to read and has all the info needed for NEM2, with the exception of not informing you what your max monthly export limit is.

Isn’t there another page that shows you the amount of kWh’s in each TOU bucket? Feels like this bill has all pieces of info one would need except for the allowable export limit per month.

Now that I have 5 bills of data it is getting more interesting. NBC’s are a lot more then I anticipated (and so is the CCA charge) but still considering my circumstances (3EV’s, one with a long commute, AC, etc) it’s pretty good. Was paying almost $1k/mo before! Since my true up cycle...

These were from my first bill post PTO. I haven’t had a true up yet (June 2024 will be first with PGE, apparently April 2025 for first one with SJCE CCA). Every month since the one I posted (4 more) has show exactly the same. They just keep adding extra rows to the table. It’s pretty...

10-15 days was there comment on filing. It was applied remotely after 5 biz days. And it wasn’t a patch, it appears they rolled me back to 23.28.2 from 23.36.1. More annoying is that that they don’t really communicate what is going on. Anyways, I’m happy it’s resolved, again, for now.

Yep, have 4x ESS (PW's). And yes, looked many times in the "My Accounts & Services" area per everyones instructions. New Blue Bill content is posted here on this thread, pg2: NEM-PS Annual True-Up Calculation [PG&E example] Wondering if newer PTO's just don't get B&W bill? Maybe they've...

Weirdly, still don’t get the B&W bill even though PTO was back in June. However, the Blue bill I do get has all kinds of details now…is that the new B&W bill for more recent PTO’s?
