Powerwall

Tesla makes this claim at the end of the answer to the second question here. Has anyone (conscious, and with a visible light on) found this to be true? Hilariously, as I was typing the word "found", our power went out. The TV (that I use as a monitor) clicked and went black, the A/V receiver...

Hi All Looking to install a PW2 with a new PV system. Are current usage is only about 12 - 18kWh a day but it will double when we get an EV. Most of our usage is at night. I am wondering what size PV system do I need to charge 1 PW2 during the day so that I can use that power at night to...

My Tesla app started showing Powerwall firmware 1.23.0 sometime today. I have no idea what might have changed. The changelog page still has 1.21 as the most recent version with any notes.

Hi guys, long time no post. We have a newer(~5 years), energy efficient (solar/electric hybrid hot water heater, high R values, electric heat etc) home, that I initially wanted to get a propane backup generator on and passed due to noise and maintenance (plus was examining solar). We've had...

While browsing the Powerwall FAQ, Special Modes of Operation, I noticed a new feature other than Storm Watch, Preconditioning. Has anyone noticed this before? I do not recall the feature mentioned in the software release notes. Seems like a very nice feature to have by default. I also...

So I took the plunge and will get Tesla solar panels and three PowerWalls. I decided to get the whole thing installed at once. After discussing with the sales person, he wasn't sure if having a split installation (since PowerWalls are delayed by a few months) would allow the PowerWalls to be...

I debated posting this here or over in the New England forum (where it would probably get few views but more local interest?); New England won out for some reason. Anyway... Liberty Utilities files for Tesla battery pilot in NH (Mods - if posting the link is a no-no, feel free to delete or...

Liberty Utilities has filed DE 17-189 with the NH PUC to introduce a battery storage pilot in NH using Powerwall 2's. They are looking to install 1000 batteries in customer residences, in a program modeled after Green Mountain Power's battery program in VT. Customers can lease 1 or 2 batteries...

I have had 3 PowerWall 2s installed about a month ago. While charging, I see very odd behavior from the PowerWalls. The attached image is what we see most days. This behavior typically starts once the solar is generating more than a few kW. Has anyone else seen behavior like this? The...

There seems to be a lot of confusion in the marketplace on this topic. Until recently, it was nearly impossible to correctly model the financial benefits of adding a PowerWall to an existing Solar PV (photovoltaic) system. But now it’s possible, using “intraval data” and software from Energy...

Has anyone seen this post make the news in the blogs? The IRS provided a response to an individual taxpayer that, given certain configuration considerations, a Powerwall Installation which integrated with an existing PV installation is eligible for the ITC. The battery characteristics...

I'm getting my site survey this week, and have been planning the PowerWall install for a little while now. I'm interested in getting any feedback on my system as it relates to how the PowerWalls are connected. Some background info. I have an existing 5.13kW solar system, and TOU metering (SCE)...

They already have wind power, now adding 10 distributed Powerwalls and one substation Powerpack. This small scale test project is going online soon. Tesla's latest smart power grid experiment begins in Canada Twitter Nova Scotia Power testing Tesla batteries in electrical system

Does anyone have access to the "Time-Based Control" mentioned on the powerwall support page? Time-Based Control | Tesla From the Powerwall home screen in the Tesla app, select Customize and then Advanced Time-Based Control. Within this mode there are two strategies ‘Balanced’ and ‘Cost...

I noticed version change but I haven't seen any change in behavior yet, anyone have the scoop? [edit: Oh heck, I see there are discussions about 1.12.0 in a firmware thread, didn't find it on searches] arnold

Well, perhaps others know of useful things this Lab has done. I don't mean just for defense contractors, but for the rest of us. Anyway, thought you'd enjoy listening. He even owns a Model S, but seem not to know much about Tesla. So far he has spent $120 million on battery research (I'm...

I'm not sure if this is cool with the sites T/C (If not mods please let me know and I'll delete immediately) I've been working on a series to be put on youtube about all of the ins and outs of Tesla ownership for those who wonder or those looking to get a Tesla in the near future. From extreme...

Done some research on this trying to see how I can maxmise use of solar while ensuring I still have enough charge in the Powerwall and car by a set time of day. It seems you can't at the moment unless you use an OpenEVSE charger instead and use code to control the charge rate. Some have modded...

I live in Las Vegas and want to get solar panels and the Powerwalls on our 3800sq ft house. We'd like to get off the grid completely but I don't think NV energy will let us. According to the online estimator, we will need 4 powerwalls for the house and EV charging. I have a few questions: 1)...

Tesla solar kiosks coming to Home Depot Tesla solar kiosks coming to Home Depot

I read all these posts on here about SGIP and load vs efficiency. My brain hurts. Are you guys overthinking or am I underthinking? I told Tesla I want four Powerwalls to go with my 10kw solar already installed. I'll get the 30% fed rebate and charge the batteries off the panels. I don't...

I am in the Chicagoland area and wanted to see if anyone has had an Powerwall installation in IL and who they used. I just took the plunge and placed a deposit. I currently have a 10k solar system with battery back up (golf cart batteries ugh!) and a NG generator. Hoping a Powerwall can replace...

Hi All, 1) Would it be possible to set up a system at home where solar panels charge the Tesla PowerWall 2 by day and the PowerWall then charges the Model S with it’s stored energy by night? Seems like a reasonable (and potentially popular) use-case, but I don’t see anything online definitive...

Hi Folks, Wondering if anyone has seen this before and can advise what may be happening. Powerwall 2 was installed in November, has been working fine although hasn’t been getting a lot of charge through the winter months. For the last 2 days once the charge has reached zero in an evening...

Mercury NZ picks Tesla for ground-breaking battery trial Mercury NZ has selected Tesla as the provider for a scalable national grid-connected battery trial after a tender process launched last September.

NOTE! This thread was originally created in Jan, 2018 and much has changed with respect to selling or buying or "gifting" a PW2 award, and it continues to change. Original thread is below. ------------------------------------------------------- I see a lot of people posting their referral...

Hello everyone, Through the referral program, I have the option to claim the Red Founders Series Powerwall 2. Unfortunately, I am not able to have it installed as I live in a apartment, so I'm selling it. I will transfer the Powerwall 2 and installation to the buyer. This Founders Series...

Others reported that their reserve percentage changed when they were upgraded to 1.10.2; This also happened to me. I had the reserve at 25% and it was knocked down to 21% if my memory serves correctly. I adjusted it back to 25% and it's remained there. I decided to write some software this...

I have reserved my PowerWall 2 about a month ago and was told that the current wait is about 12 months. So in the meantime, I would like to do some research and see if there is any government and/or tax credit program which I can take advantage of. I live in Northern CA with PG&E as my utilities...

Tesla/Solar City doesn't offer solar options for flat roof homes in the northeast. They offered no advise as to which solar company could assist, and no information regarding the development of a Solar City option for modern flat-roofed homes. Just to be clear, lots of flat roofed homes and...

I also posted this on Tesla forum with no reply. Hi all, My 1x Powerwall was installed 2mo ago and has been online for a few weeks now. As a new and excited owner, I find myself checking power flow and whatnot on an almost daily basis. My PW is set to Self-powered with a 40% reservation...

Hi, Anyone who has a Powerwall 2 (Founders Edition) from the referral program and does not need it, I would like to buy it from you. I am based in San Jose CA. Please contact me if you do not plan to use it and I will buy it from you.

Oh snap! There goes every other EV out there.

*** For Sale - Redemption Code for Signature Black Wall Connector or Model S for Kids *** Hello everyone - I have received a redemption code for either the Signature Black Wall Connector or Founder Series Tesla Model S for Kids I have no need for either so if you're interested send me a PM.

Has anyone in Arizona either been given a firm date for their install to begin, or have a completed install?

Thought we should open an area for all the funny things than are found......

We have a home with a flat roof located on the eastern-end of Long Island in NY. We also have a power wall 2 on order and would like to add solar panels. Solar City/Tesla does not install panels on flat-roofed homes located within northeastern states. Presumably because of the potential weight...

Does anyone know if: 1. The powerwall 2 can charge from the grid on cheap off peak electricity? 2. The powerwall 2 can act as backup during power cuts? I don't think these features are available yet but wanted to check. Anyone know if they're in the pipeline?

This is currently posted on the PW FAQ: Can Powerwall charge my Tesla vehicle or an EV? Yes, Powerwall can provide stored solar energy to your EV through your home electrical panel. However, there is no direct connection between Powerwall and the EV wall connector. Powerwall FAQs Color me...

I had my wall installed yesterday. I got connection errors all day yesterday (on the app) but the app is now running fine. My Power Flow screen shows 1.6kW from solar with 1.4 going to the grid and the remaining .2 going to the home. Nothing is going to the wall and it is greyed out. Reserve...

We had two Powerwall 2s installed about a month ago, and the system hasn't worked properly during that whole time. The case is currently escalated to their software engineering department, and they're "still investigating". This is the only status update I've been able to get from them, and...

I got home from work and plugged in to my HPWC. I normally get 47/48 A 37 mph charge at 12kw an hour. In the middle of the night the wind was owing hard and the lights flickered on and off for about 10 seconds. I went out to the garage to check, and the car had some errors thrown up about...

I called support today about two issues - one was being stuck on 1.6.0. They pushed 1.9.2 PW was in stopped state after upgrading - I had to push the START POWERWALL button to get it running. Does seem to accept changes to reserve capacity now. No other issues (apart from manual start)...

Hi, all... I'm looking for your opinions on an home install that Tesla Energy is currently designing for us. I know many of you have done your full due diligence on the economics of your systems, many of which are also in Northern California... as a solar newbie, I'm hoping to get feedback on...

I have a question for those of you with Powerwalls in cold areas of the world. I am interested in adding at least one, possibly 2, Powerwall 2s to my 5.4kW PV system. I live north of Boston MA and it can get pretty cold at times in the winter with limited sunlight. I am wondering how the...

I utilized the referral program to get a quote going to upgrade my solar system. With all the EVs we drive, our system designed to cover 80% of our usage is below 50%. After providing utility bills and specs on the current system, I was told that they will not install on homes with an existing...

Hi All, I hoping you can help me decide if I should go ahead with the SolarCity contract. I am aware that I will not be saving money, but I am willing to pay some extra amount to 1) be a part of the Tesla revolution and support the company, 2) have a backup for power outages (my alternative...

We would like to get a couple of Powerwalls, but we are having difficulty finding an installer in Northern California / Bay Area. Does anyone happen to know of any?

Hello everyone. We are in the process of building a large home (9000 sq ft) in a PGE area with poor power reliability. That means high cost (esp in band 5 usage which a home like this one would definitely hit), and dealing with reliability means a generator (since I travel a lot and I want my...
