The last time I called Tesla Powerwall North America support for an urgent problem, they could not solve my problem and told me that they didn’t have enough coverage for anyone knowledgeable to help me in less than one day, so they asked me to call back at night when the Australian support team...

For this part I see you modify the weekday rate schedule in the app to eliminate the partial-peak periods and curtain the peak period by 3 hours. But how do you automate switching the Powerwall coverage during the week between OhmHour/some weekdays vs your presumably now “regular” weekday days...

If you have no charging schedule set, this is exactly what is supposed to happen according to the manual, p.131, irrespective of app usage. That is, after plugging in and car is in park and battery conditioned (and SOC is below threshold of charge limit), you have to expect charging to commence...

@MorrisonHiker @Dan123 Thanks guys — you beat Powerwall support response time by a long shot!! Telsa NA telling me to wait for the Australian support team to wake up, seriously?? In the meantime I tried to change various settings to force charge, and also cut and reset solar breakers, etc...

Hi all, I’m currently under yet another planned PG&E all-day power outage and have gateway software 1.37.1. Although previous power outages were handled fine, this one started with Powerwalls at 50%, but Gateway immediately started outputting 61.3Hz (at 240Vac) and thus never enabled Solar to...

That inverter has max output of 47.5A. According to NEC, you multiply by 125% and round up to nearest available breaker (unless you are less than 0.5A above one). That means 60A breaker is the recommended breaker for you so sizing is not the problem. There is a spec note on this from...

Sent PM.

Not sure about the Amazon one, but the ModernSpare tire has 115 load rating (2679 lbs.) which exceeds the stock wheels. I calculate it has about 1” smaller overall height (diameter), so Pi” smaller circumference, which is manageable. If the wheel itself is certified to sufficiently high load...

Within the first 5 weeks after installation we racked up a total of 37 backup hours in 5 PG&E planned (fire prevention) and unplanned (PG&E equipment failure) outages. The longest single outage so far has been 17.5 hours. The future is bleak (but a bit brighter with Powerwall).

Yes I think option 2 is the best choice. That is what Tesla designed for my installation. They installed a new 200 amp generation panel containing 4x 30 amp breakers for the Powerwalls and relocated 80 amp breaker for existing solar. They used an Eaton panel that looks just like yours but with...

What you describe is typically called “peak shaving” to reduce energy demand charges. The commercial version of the Powerwall, the Tesla Powerpack, seems to have this capability/algorithm as one of its main features. Powerpack - Commercial & Utility Energy Storage Solutions | Tesla However the...

Where are the jump terminals on the PW? I don’t see any — can you share a pic?

Directly under reset button on the brain box :)

Does the plastic face of your 14-15 plug (the side the faces the UMC) have a black or grey color (before the melting, in case it is changed now)? In your first photo, this would be the side that is facing down and resting on the surface.

Looks nice, thanks for making this open source! I use tesla-bitbar (therippa/tesla-bitbar) which handles multiple cars well (I see is on your ToDo list) and sorts them by their personalized name and is lightweight, but has not been updated with recent features like Sentry Mode. Here is a...

Hi @Ulmo, thanks very much for your early posts, photos, and home website describing your Powerwall install. They were invaluable to me. I am right on the SC/SC boundary on SC side (yes your side) and here are some TMC posts on the MBCP CCA. I received 3 postcards (none packaged with the PG&E...

Do you have any evidence for this? If true I would presume the machine learning part would be done off-site on server side to take advantage of a global data set, which would require network communications back to gateway which you could monitor on your local network. I would say that if you...

I was able to log in as installer just by following the instructions here (Monitoring from Home | Tesla) using default Gateway password.

It’s odd because I’m on 1.34.2 / TBC / cost-saving and all my graphs look like your good graph, which is what I would call 100% self-powered by Powerwall during peak. (See my other thread on a bug in Tesla calc of this percentage, but the graphs and sum totals agree). And the only time I’ve seen...

If you look in the gateway, the default location for the CTs is called “site” and they are around the top feed bars. They are oriented correctly if the label saying “this side toward source” cannot be seen (it is facing toward back of gateway).

Which page do you mean by Power Guide? Do you mean the Energy Usage page with the graphs and numbers following that (first image I posted) which shows 4 things including consumption? PS. I decided to report my findings in the original post as a bug since I’ve confirmed it for every day since...

I forgot to ask: did Tesla (or your installer) do a simulated grid failure after installation was completed? Tesla had that on their to-do list and said they were looking mainly at interaction with solar (for this reason they wanted to do it before it got too dark, and they were running out of...

24 hours (was for me and that was what manual quotes) or as much as a couple days according to reports here. TBC appears without software update after it monitors your usage pattern for a day or so. Maybe it will be speeded up if you don’t do a lot of grid failure tests during that period :)

@MorrisonHiker Thanks! Even though I can see Powerwall tab, I lack the “Energy” tab after tapping notifications (which for me only goes to what you see in 2nd image for Vehicle). I did try log out/in and reinstall app, and both iOS and Android show same problem. I have reported problem to...

Can someone who has both a vehicle and Powerwall show me what the notification page looks like? I cannot get Powerwall notifications, nor see any options for enabling it in Notifications tab (since installation, I have had several grid failures ranging from 19 minutes to over 4 hours). In...

Simplified question: If you power all loads 100% with Powerwall during peak (as many of you do), shouldn’t your self-powered percentage be shown as 100% Powerwall during the Peak time? All solar during that time goes 100% to grid and shouldn’t be counted in the self-powered percentage. The...

I called them, for my Mom, and got switched over without any hassle. They just want to see a permanently installed electric heat source. I also learned that if you have building connected to separate electric meter but without ANY heat source and without any hookup to gas/propane (like a barn...

I read over some other EV-A document and it was not clear to me whether the 800% applies to net energy or to total supplied by PG&E before generation credits. Both are tracked in billing. Do you have a pointer to clarify? Thanks. EDIT- PS. It seems to me that all people on EV-A (even...

HA, @GenSao just beat me to it. On the same site, PG&E's "Final Decision" Rates, Part 1: Residential Rates, the webinar has more info on the grandfathering. First I believe one big change not mentioned above is that EV-A will open to storage customers as well (with no electrical vehicle) and...

As mentioned above, the total installation charge is $4750. $1000 of that is hidden conduit. The rest ($3750) is indeed on the high side. For more perspective you’ll probably need to chime in on any challenges or site constraints of your particular installation. For example, if they need to...

Tesla Powerwall 2 specs for transferring house loads from on-grid to off-grid: Backup Gateway detects grid outage. Backup Gateway sends signal to Powerwall to prepare for off-grid operation. Backup Gateway opens contactor within approximately 30 ms of outage detection, physically isolating the...

@Shygar Could you share any tips on setting up Raspberry Pi for polling the Tesla Gateway and getting the data properly to pvoutput.org including the extended data set there (which holds the Powerwall info)? On their site I see a lot of discussion about using a Windows application for this, but...

FYI another thing local install group told me is they have yet to see the new PW revision in person. It may be they first show up in locations where new Gateway is available.

Thank you! I stand corrected. Not sure why Tesla told me 2 as it affected my system design, but fortunately we changed layout to fully floating later on.

There are basically 3 states: Charging, Discharging, and Standby. What settings have you put in on the “Customize” section of the app? For example if you have chosen “Backup Only,” then PW will stay in Standby all the time (except when it needs to charge to stay above the set reserve capacity)...

I’ve got things running so that PW charges from solar at either partial-peak or off-peak times, and discharges during peak times. To do this I use time-based control & cost-saving option. Software 1.34.2. The calculation of self-powered percentages seems screwy. I’ve chosen a simple example...

Thanks. I had gone through various parts of that huge tariff document and that was why I asked about the interconnection fee. I am on NEM1 and couldn’t find the place where it is required, except Tesla told me it was required effective Jan 2019, even on NEM1 and sent me a pre-filled PG&E form...

Your solar production is certainly not being wasted in the current configuration. During times when your solar generation exceeds house load, the difference (yellow-blue) is being fed back to the electric grid. It is at least helping someone else, and hopefully you are getting credit for that...

From my own experience, stacking Powerwalls 3-deep is not an allowed configuration (max is 2). That was what I was told by Tesla, but don’t know if this varies by country (but certainly true in US). If true, your 3rd one would need to go to the side. If so I have some info for you and I think...

Call 877-79TESLA. That is 24hr number. They can look at logs remotely and schedule service or elevate (also for roadside assistance). Good luck!

@Tam is correct that first step should be to look up the terms attached to the car on her My Tesla account. Here is an example from mine which will transfer, but these were the most expansive terms which were progressively phased out. Sometime (overlapping with Model X), the transfer clause...

I was able to do this by writing several times to the referral program email (the one that sends you notices) until someone confirmed my choice. However the 2nd Wall Connector arrived 6 months after the referee car purchase, and the referral program changed one or two times during that period...

I love the new Gateways which look like baby Powerwalls! I wish they would bring them to the US. Are you on 3-phase power?

@wwhitney I have a few questions: 1) The two-page summary of your proposed system hookup wrt PG&E I think is here: https://www.pge.com/pge_global/common/pdfs/solar-and-vehicles/net-energy-metering/net-energy-metering-overview/nem-multiple-tariff/NEM-Paired-Storage-Frequently-Asked-Questions.pdf...

@RoBoRaT That looks awesome and very symmetrical. Is that a lightweight tile roof — what is the method for mounting the standoffs beyond removing tiles? How did the process of relocating plumbing vents go? And I cannot see where the bathroom vent moved to.

@MarkS22 It might be easier for you to move out of NJ so you never see rain again.
