be very wary of TESLA
Tesla will run your house from the grid, charging you . As I type this my solar is producing more than enough and is charging my battery, BUT Tesla has control over the app and inverter, forcing my solar NOT TO run my house. There is plenty of solar and I have more than one battery, so I do not need the grid, yet I still get charged although I DO NOT WANT TO USE THE GRID.
I am not permitted to disconnect from the grid, I must pay a supply charge, although I do not want to use the grid.
DO NOT USE TESLA.
They are very good at telling you what you want to hear, and are very good at taking your money, they have made an art of it.
No one has been able to explain my screen shots clearly showing grid power in when it is NOT needed.
Losing capacity fast and no response from Tesla customer support
I have had a Tesla Powerwall 2 for 2 years and it is down to a discharge capacity of 10.9 KWh. It is rated at 13.5 KWh and the warranty is for it to have 70% of original capacity at 10 years. As it is already under 80% capacity at just 2 years old I have called my installer to investigate and they advised it is a Tesla issue. I have since emailed Tesla customer support on multiple occasions. I have received NO RESPONSE.
If the capacity degradation continues at the current rate I will force Tesla to replace the Powerwall 2 as soon as it drops bellow 70% as per their warranty. I am disappointed that a supposedly premium product has so little after sales support.

Wow... just wow.
We had our Tesla Powerwall 2 installed nearly a year ago thanks to AHE Group (who i highly recommend) l and it is amazing.
It is linked to out 10kW Solar and because we live on acreage where we can get powerlines taken down by falling trees we have it running off 2 separate Inverters.
1x Inverter sends the solar to the Mains as usual.
1x Inverter sends the solar directly to the Powerwall 2 and then to the Grid - this means we can still generate and store in a blackout.
Last month our neighborhood had blackouts for 2 days running... we have pow...

Does my power co (AGL) dislike my Powerwall 2...
I've had my PW running since 23 Dec 2020 (3 weeks), and in that time I've paid for just 25 cents worth of power. (Which in itself is weird because the battery has never been empty, and there has never been any reason to draw any power from the grid). However, it has possibly (or coincidentally?) triggered AGL to REDUCE all of my power rates (peak, off peak and shoulder) by a substantial 15% (approx). My Feed in Tarrif remains at 20c however.
The powerwall (or more accurately the Gateway 2) has also saved us from a string of blackouts already ...(see image). Ignore the earlier 3, they were done on purpose during installation. A previous complaint by someone not being able to access the data stored in the cloud appears to have been fixed by using the 'download my data' option. Find it in the PW App here : Choose the Power Flow option > Choose any one or more of the 4 icons to display the ENERGY USAGE screen > Scroll to the bottom of the page to download your data. The only (trivial) issue I have encountered is the storm watch function in the Custom Settings area. I have it ON, and it in the hours leading up to the big storm we had a few nights ago (15 Jan 21) the software was supposed to fill the pw to maximum from the grid - which it didn't. (It wasn't a problem though because we didn't lose power, and we had about 85% battery full when the storm hit anyway. I will report this to Tesla, and they will no doubt fix it, if it is a problem. To end this, I'll also have to mention that I'm now addicted to the App, and wondered if there was a matching App for my Apple Watch, so I entered powerwall in the app search, and lo and behold, now I have access to my system instantly (I have it set up as a 'complication' on my watch face). A glance tells me the % full the PW is, tap it, and it shows the power flow (see image) and a swipe left shows the stats for the 4 icons (House, Solar, PW, and Grid) . It's a shame Tesla didn't write this because they would have earned the $4.50 I paid for it. BTW this the first and only App I've ever bought. On the negative side, they also want an additional fee for the Mac version which I think is unfair, so I'm not buying it.

Most versatile battery on the market
We have our PowerWall 2 (PW2) installed for over a year. I did 3 part video review on it published on YouTube.
I think ProductReview will embed the video. My channel will have more reviews on the topic as well as my thoughts on Virtual Power Plant (VPP) offered by Tesla and various electricity providers. If you would like more information feel free to search for Greg Yurchenko and check the channel for content.

Purchased in March 2019 at Keen 2B Green for $12,450.00.
I have had the Tesla Powerwall for just over 3 months now, so thought i would share my experience.
I had the system installed at the same time I had my old solar system (3kw) replaced with a new upgraded Tindo (5.7kw) system (would go larger but limited by roof space).
During the summer months the system has no problem fully charging the Powerwall most days and exporting excess power to the grid. In winter production falls and exporting is limited - the Powerwall does its job and stores most of the power generated (not consumed by the home) to ...
Great when it works
I have had the powerwall 2 installed for a year and it worked just great. The first thing i noticed as a problem was that the app just showed the battery in standby and no data. I assumed this was just a connection with the model issue but have since found out that this means the battery is not working. Now I can't see any of the real time monitoring data (ie should i turn on the air con now or not), have no back up protection and no battery (had managed to get to never drawing from the grid overnight).
All I keep hearing from my installer is ...that Tesla are going to contact me in the next few business days. That as in August and now it is late October. Are they going to go out of business and they are just fobbing us off? Otherwise why wouldn't they get in touch? I used to love their product it and spruke it for them far and wide - now i just feel let down and disappointed.
Purchased in July 2018.
Didn't get to first base.
Completed Tesla's online form for them to contact me about buying and installing a Powerwall. The website stated "We'll do our best to reach you within one day." One day later, not having any contact with Tesla I phoned their sales team. Was on hold for a while then the messages started saying they were busy. This then moved on to a robot voice with a American accent, it said something about "energy is gone" leave a message. I didn't want to leave another message, however, as I didn't they hung up on me! I phoned back and the same thing ha...ppened. I would have loved to review the Powerwall, however, given the lack of communication and service at Tesla I am far from confident of being able to contact them if I had a problem with the installation etc. Now back to researching another battery that comes with a company who are customer friendly.
Tesla Powerball 2
After 3 months of operation I find there has been a substantial reduction in my power bill. I have not changed my usage habits but electricity bill has gone down substantially .
One year of Powerwall 2
I installed a Powerwall 2 to complement my 4.6 kWh solar power system on 16 December 2017. I monitor performance constantly and can report that in the 12 months since installation I have purchased 51 kWh of power from the grid, and over the same time I have exported 5,634 kWh to the grid. In selecting my retailer and 'plan' my only consideration is the number of kWh feed-in required to cover the 'poles and wires' service charge. I did quite a bit of comparative research and selected Click. I am very happy with Click and delighted with the Power...wall. A major benefit I find is the ability to charge my plug-in hybrid Mitsubishi Outlander using my own power in the evenings. The Powerwall is connected to provide 'whole-of-house' backup in the event of a power outage and gives the security of keeping the solar panels active and charging during a daytime outage. I have no regrets about making this purchase.
Good hardware, not happy with the software
The good news is that our last electricity bill was $17.62 for 3 months of spring (September-November). Our theoretically 4.8 kW PV system (actual maximum output is 4.1 kW) plus our Powerwall 2 made us self-sufficient for most of that time. We exported nearly 1 MWh to the grid, which paid for our daily connection fee.
The bad news started at the beginning. We contacted Tesla in May 2017. The system wasn't installed until March 2018, and that only happened after we put in a complaint about our process to the EnergyAustralia complaints departm...ent (EA was the installation partner). So we missed all the savings we could have had over that spring and summer. The other bad news is the software. You can only run it via an app on your smartphone, you can't run it on a normal Windows computer. You get no access to the raw data, just graphics showing the past day, week, month etc. I would like the raw data so I can figure out which are the best tariffs for our household. Worst of all, the app only works sometimes. Rather than provide a fully functional app, Tesla's answer is that you should delete and re-install it. Even that only works sometimes. I deleted and re-installed the app an hour ago, and rebooted the phone a couple of times, and I still have no access to the system. At the moment that's just a mild annoyance, but it becomes more serious when you want to switch the system to backup mode because there's a big storm on the horizon, or a heatwave that raises the risk of blackouts. Would I buy Tesla Powerwall 2 again? I'm not sure, because I don't know what the alternatives are like. We chose the Powerwall 2 because it had the best technical specs and the smallest size (we have limited space). When it comes time to replace the system I'll pay more attention to the customer service aspect of product reviews. Hopefully by then the competitors will have matched Tesla's technical specs, assuming that Tesla is even around by then.
It is a dream product
Got my Tesla Powerwall 2 installed just in time for the summer solar year season.
It exceeds my most positive expectations..
Connected with my 4 Kw PV system export to grid is down to 2 Percent of output.
I am self sufficient by 75 percent.
The Tesla can give 5 Kw back instantly.
It can take 3.8 Kw to recharge quickly.
It runs empty nearly every night.
The Gateway information on my Mobile keeps me entertained all day.
Great product when it works
Installed for over 12 months and with constant interruptions mainly due to incorrect installation. The phone app is used for control of the system is great, but is not working and I have been told could take them 2 months to get around to repair. They seem to have a lack of people in their service area. Previously a man traveled from Adelaide to repair system.
Great battery, good installers and better support than most companies
My Powerwall 2 has been installed for 10 months and has been working well. The installers did an excellent job and, when the unit needed to be replaced, it was Tesla's telemetry that identified that there was a problem. Replacement took a few months but the unit remained fully functional. I can't think of another company that has done this - you have to chase most companies to get warranty work done.
Electricity bills are now negative for most of the year and our frequent blackouts are a thing of the past. Highly recommended for those who suffer a lot of power outages but probably not there yet as a money saver.
Even the limited control can be broken by Tesla at a moment's notice
By altering the amount of energy reserved for backups, I'd managed get this thing to provide power when it's most valuable. Well, until today, when Tesla made some quite unnecessary changes to the firmware. Who owns this battery? Do I or does Tesla? I thought I did. Maybe I'm wrong. If I had to make the decision again, I'd avoid any product that's tied so tightly to its manufacturer, and whose functionality can be changed by the manufacturer without my permission after I've paid for it.
Questions & Answers
Is your Powerwall capable of running any sort of air conditioning system in your homes?
Yes it is but it depends on the size and how long you run it. My little bedroom air-conditioner would most likely be able to be run all night off the battery including all of the other things in the house like the fridge etc. That little Aircon would be drawing about 1 kW an hour. But my big whole house air-conditioner would drain the battery in about two hours. That is because it draws between five and 6 kW Per hour. So it will depend on what size Aircon you want to run and how long do you want to run it for.
