About Tesla, Solar Batteries

Tesla solar batteries review

Tesla, Inc. was founded in 2003, originally as Tesla Motors. Tesla is headquartered in the USA's San Francisco Bay Area, with office locations around the world (including Australia).

After cutting its teeth on electric vehicle development, Tesla then expanded into commercial and home battery storage. The company arrived on the home energy storage scene accompanied by great fanfare with the Tesla Powerwall battery back in 2015, which was followed by the Powerwall 2 in 2016.

Tesla has grown into a huge company in terms of market capitalisation - a whopping USD $143.6 *billion* as at late January 2020. 

Anyway, back to batteries - the following are some basic specifications of the Powerwall 2:

  • Usable Capacity: 13.5 kWh
  • Power: 7kW peak / 5kW continuous
  • Dimensions: 1150 mm L x 753 mm W x 147 mm D
  • Weight: 114 kg
  • Warranty 10 years

The Powerwall is produced in the Tesla Gigafactory in Nevada USA, which also manufactures Tesla Model 3 electric motoers and the company's commercial/utility storage solution, the Powerpack.

Pricing And Supply

Supply of the Powerwall 2 was an issue for quite a while in Australia, and then there was a major price rise in 2018 - followed by a not so major price decrease in 2019. So, Australians have had it a little rough with the Powerwall, but its high profile through extensive media attention have seen plenty installed here and interest remains strong.

The cost of Powerwall 2 per warranted kilowatt hour (see below for notes on warranty) is around 31 cents - not the cheapest, but far from the most expensive of the systems we have listed on our battery comparison table.

Blackout Capabilities

The Tesla Powerwall 2 is an AC Coupled battery that comes with the necessary hardware (Tesla Gateway) to provide blackout protection, backup and off grid functions.

Powerwall's "Unlimited Cycles" Warranty

Tesla offers a 10 year "unlimited cycles" warranty, but this only applies to solar self-consumption and backup use. Any other application (such as participating in a Virtual Power Plant) or combination of applications sees the warranty cover drop to 3,200 cycles – about eight years’ worth if cycled once a day.

Reliability Testing Results

The Canberra Battery Test Centre has been putting the Powerwall 2 through reliability testing. The test battery arrived with a fault and later developed another that resulted in it being replaced.  Results published in September 2019 indicated capacity estimated at 96% after 640 full cycles.  If  maintained, the Powerwall 2 will stay well within the minimum capacity provided by its warranty.

While not perfect (and Tesla hasn't been overly fond of us pointing out issues), as far as home solar battery storage goes at this point in time the Tesla Powerwall 2 is probably a good choice among what is available.

Telsa is great at marketing, but how is the Powerwall viewed by those who have one installed? What about after sales service and support? We're inviting Australian Powerwall owners (whether they have the original or Powerwall 2 model) to leave their rating and review here.

The Tesla App is a great, easy to use tool, which easily allows us to arrange our energy usage to maximise our solar self consumption.

One of the reasons we went a large system with battery, is we have transitioned to a fully electric house. I already have time of use metering, which we were using from charging our electric car, and heating our hot water (via a timer) This house originally came with gas hot water and a gas cook top. Our plan for energy self sufficiency was to migrate off gas, and install more solar.

Now we have the solar and battery, we are heating the water between 10am and 4pm off Solar, and have started charging the car during the day off solar as well. The Battery takes care of the power during the peak and shoulder evenings, and most or all of the night, and will help out more in winter and on cloudy days when required.

Tesla Battery couldn't be happier with it, Rural Property backs up large house and shed when power outage

We purchase Tesla battery system after having solar for some time because when the power went out our solar went down and we were without power, Tesla Battery does a great job it has backed up our large house and sheds on Rural Property for up to 4 days at a time during hot summer. we couldn't be happier with it, Tesla battery was our best investment and has added property value.
Tesla Battery has multiple running programs and is so easy to look at and set on a app on mine mobile, I can look at it and make adjustments while at work or even on holidays.
I can not recommend Tesla Battery and Allstate Solar more, they are easy to contact and happy to talk you through what ever you may need, great friendly staff.

Not only does the PowerWall look great, but it doesn't take up a lot of space either. The companion Backup Gateway 2 unit also looks great and also doesn't need acres of space on the wall of the house.

The Tesla app is easy to use, presents the stats of your power generation and consumption in a way that is easy to understand as well.

The single PowerWall has more than enough capacity to handle our requirements and looks as though it will run the house at night with ease on most occasions. Being able to keep the fridge running during a power blackout also means we wont be throwing out spoiled food like we have had to in the past.

Very happy with the Powerwall. Has already covered us through two blackouts, but importantly addresses our power usage when solar is not available. So far the solar system has been able to fill the battery each day, and we generally discharge it overnight and in the morning. Additionally, the battery jumps in throughout the day to meet excessive demands of the cooktop/ovens/aircon to help minimise our grid usage. The Tesla app is simple but very effective for monitoring the entire system (including solar generation).

Great product

We installed the Tesla powerwall2, battery and solar panels, in October 2020.
The system has supplied, 99% of the electricity we use, since day one of installation.
(52 % Solar, 47% Powerwall Tesla performance lifetime, on the app) and any excess power produced, is being exported to the grid.

Super Slick Tesla Battery

As an Architect I would and have recommended AG Solar to my clients. Especially after upgrading my recently installed system with more panels and a Tesla battery. The Team was absolutely fantastic in all aspects of knowledge, response, service and installation. I have been impressed with the performance of new system and the cost neutral savings. The Tesla App is amazing and I cannot stop checking it. I am contemplating another Tesla battery to future proof my residence.
Keep up the great professional all-round service.

Control of charging Tesla Powerwall Powerwall

I have had my Tesla Powerwall 2 for a couple of months now and I am wrapped in the amount of control it gives me plus showing key data

Once you have a battery it will need charging.
This will happen automatically when the sun is shining but what happens when the sun doesn't shine? The battery cold run down to minimum capacity (this can be preset with the Powerwall) and then start charging from the grid. But what time will this be? perhaps in afternoon or evening when you are on peak rates which is not desirable.

With Tesla you have three modes (I quote their description)

Self powered: Use stored energy to power your home after the sun goes down
Recharges next day when the sun shines charges from the grid when minimum capacity reached
Backup-only: 100% of your Powerwall is reserved for backup at all times.
Uses the grid to charge to 100%. If you are currently on off peak rates select this mode to charge your battery.
Advanced Time-based control You can set your off peak and shoulder times so that Powerwall will charge at these times.

If you live in an area where you have blackouts due to storms there is also a Storm Watch feature which detects incoming storms and will ensure that the battery is charged before the storm. I haven't had the need to use this feature.

The Powerwall also supplies graphs which show Home Usage, Solar energy produced, Energy usage in/out of the battery and Energy Usage into and from the Grid. These can be shown on a daily , weekly, monthly, yearly and lifetime basis.

All these features are available from within the Tesla app.

The photo shows Power Flow which I grabbed when I had the aircon and and there was little sun. Note: You might be able to see the little arrows indicating that the Powerwall is supplying 5Kw, the solar panels 0.1Kw and the Grid 1.1 Kw making up the Home consumption of 6.2kW

I can now see why the Powerwall has a premium price but if you are a data junky you are very happy.

The Powerwall 2 charges quickly with the sunshine. We utilise the battery power as the sun goes down. So far we have been totally reliant on battery power in the evening and overnight. The battery is still well over 50% charged by the morning. A great feature is the Storm Watch option. This ensures you have a fully charged battery in the event of a power blackout due to a pending storm.

Whilst the formal payback period for the battery is about 12 years, this will shorten considerably if feed-in tariff reduces significantly, as we expect it will. It is much more valuable to self-consume power than to export to the grid, both for us and for the grid. The more batteries that are installed, the more solar and wind can be added to the grid, and the transition to low-emissions energy can be accelerated. Working as fast as possible towards net-zero electricity is what we need to address the Climate Emergency.

Works extremely well. Carried us through a 6 hour power outage when poles were replaced. Very good software to monitor the system. Does everything we had hoped for. When prices drop in the future we would look to putting another one on but already we are supplying about 80% of our power through the panels and battery as well as exporting electricity even on cloudy days.

Great overall benefits associated with using Tesla. It. Barges from AC so it doesn’t need a hybrid inverter. This opens up your options for inverter and generation size. You automatically qualify to join energy Locals for very cheap electricity rates. You receive a generous rebate on the cost of the battery and you can monitor the performance of the entire installation via their app. The battery is adequate to run the house overnight if you have modest evening consumption but larger families should consider 2 batteries as 13.5kwh doesn’t goe a long way if you wanted to run heaters or A/C all night.

This is our second installation by Solaworx. This battery fits in well with our two individual solar panel systems. We have a 3kw single (ena) inverter system; and a 3kw individual panels (enphase) inverters system. The latter installed by Solaworx.two years ago. The Tesla battery has an online monitoring app which collates the data from our overall system and it is efficient and impressive. We are very pleased with the total package.

I would like the ability to export the Tesla battery when I want which is not available. Nothing to do with the installer.

Also there is no ability to set the custom price framework to suit more than one peak price period such as when you are using wholesale prices like anmberelectric.

Ideally it should be able to receive the 5 minute tariff adjustments from the wholesaler of choice. But if it can't do that it should have a manual mode that can be set by a local machine operator as to what the owner wants it to do ie export, or charge.

If the battery is charged during the day then most evenings it will last for normal use and overnight heating of hot water. We installed the battery to optimise a 10kw solar system but as importantly continuity of service – we have 6 to 10 outages a year due to our remote location and trees bringing powerlines down.

The Tesla battery app is easy to use and program and provides up to date information. The ‘storm watch’ function is good for ensuring that we have enough back up power.

It is an elegant looking battery, we have it installed in a machinery shed so it is out of the way, no significant noise, just a fan from time to time, It has coped with outages and transferred to standalone operation flawlessly and without interruption.

I would recommend this battery, especially where people have a higher risk of power outages.

After our own month-old analysis into the nature of our usage, it was the best decision we made due to the nature of our usage being split equally over solar hours versus non productive productive solar hours.

All suppliers recommended smaller installations minus battery backup to secure their sale. This would have made our pay back recovery period longer and lead to our questioning the success of the installation. We are mostly 100% covered on daily usage except when obviously bad weather changes our solar production. This includes the use of aircon and heating by day..

The tipping point arrived with combined rebates and discounts, so just had the battery installed this week, after assessing its relative merits for about 12 months.
Early days of course, but for our usage I believe the payback and peace of mind will be worth it. Day 1, 36 degrees, battery fully charged before midday, 98% self-sufficiency 20+kWh to the grid, ran the air-conditioning after dark for a couple of hours, happy days.

Day 2 19 degrees, cloudy raining, windy. battery fully charged just after midday, still 98% self sufficiency 7kWh to the the grid.

The litmus test will be how things go next winter.
