Description

With double the energy of our first generation battery, Tesla Powerwall 2 – 13.5 kW can power an average two-bedroom home for a full day. Compact, stackable and with a built-in inverter, installation is simple, either indoor or outdoor.

As an end user, from January, 2017 you can order your Tesla Powerwall 2 – 13.5 kW directly from Tesla. If you do not have a Tesla representative in your country contact us. 

The Tesla Powerwall 2 is one of the most affordable home battery in terms of cost per kWh.  Powerwall 2 economically meets the daily needs of the average family household. Powerwall 2 has a long life due to its liquid thermal control system regulating Powerwall’s internal temperature to maximize battery performance in even the harshest climates.

The Powerwall 2 also has in integrated internal inverter to convert DC energy to AC energy which is what your household runs on, which lowers the cost of installation and complexity of installation and can be added to an existing solar system as a ‘retrofit’ unit or as part of a brand new solar system and battery combination; ask us today about ordering yours. 

Power in a Power-cut

In March 2019, Tesla released the ‘Backup Gateway 2’ which allows you to use the electricity stored in your Powerwall in the event of a power-cut.

Of course you might argue, “I never get power-cuts!” For many people that will be true. However, there are also many locations in the UK where power-cuts are surprisingly common. If that’s true for you, read on…

With a Backup Gateway, you gain two major advantages if there is a power-cut:

  1. You can power devices in your home, using electricity stored in your Powerwall, and
  2. If you have solar panels, they will continue to work, providing electricity both to your home and your Powerwall.

Point 2 is really important. Solar inverters have to – by law – turn off if there is a power-cut, otherwise the electricity from your panels might electrocute an engineer working to repair the line.

However, the Backup Gateway gets round this problem. It completely isolates your house from the grid. In this way, the Backup Gateway makes your solar inverter think it is still connected to the grid, and so it carries on working.

In addition, Backup Gateway 2 for Tesla Powerwall provides you with energy management and monitoring for solar electricity self-consumption, plus time-based control. All this is managed via the Tesla app.

Tesla Powerwall – who is it for?

The Tesla Powerwall is a premium product. There are lower price range products out there, with similar storage capacity, but few as good value as the Powerwall. 

Typical buyers include:

  • Tesla car owners with solar panels (if you own a Model 3, Model S, or Model X – what are you waiting for?)
  • Other brand EV car owners with solar panels
  • People who want to make use of smart tariffs
  • Customers who want an aesthetically pleasing, all in one product
  • Home owners who would like to mount the battery outside
  • Customers who suffer from power-cuts
  • People without solar panels who want to charge the Powerwall with cheap, off-peak electricity at night and let it out during the day when prices are high
  • Tech geeks who want to monitor all the energy flows via the Tesla app

Lithium ion batteries
Batteries used in home energy storage typically are made with one of three chemical compositions: lead acidlithium ion, and saltwater. In most cases, lithium ion batteries are the best option for a solar panel system, though other battery types can be more affordable.

In short, Yes the powerwall is worth it for homeowners who are looking to save even more money on their energy bills. However, you will need to make sure you generate enough energy, on the other hand there are several other battery manufacturers out there with similar products at a better price range. With that being said, a Tesla powerwall is one of the best solar batteries you can find on the market today.

Solar batteries still cost more in some countries than a standard diesel generator, but they can provide backup power without producing greenhouse gas emissions. If you have a standard solar panel system, you’ll still lose power during a power outage because of how your panels are connected to the utility grid.

Home solar batteries last anywhere between 10 and 15 years. If you decide to install a solar battery today, it’s almost certain you’ll need a replacement in the future to match the 20- to 30-year lifespan of your solar power system. With all this, the true lifetime of a solar battery is defined by the used battery cycles and ambient condition where the battery is stored.

In general the Tesla Powerwall lasts for 5 or more years beyond its 10 year warranty. It doesn’t decline in storage capacity too rapidly. The household is a large user of night time electricity. The Powerwall is used at close to its full capacity.

Tesla has a network of high-powered Superchargers located across North America, Europe and Asia for Tesla vehicles. The company also operates a Destination Charging program, under which shops, restaurants and other venues are offered fast chargers for their customers. Although Tesla operates a number of production and assembly plants, the company’s most iconic facility is the Gigafactory 1 near Reno, Nevada, where Panasonic builds 21-70 cells for Tesla batteries. Tesla also manufactures the Tesla Powerwall, Powerpack batteries, and solar panels (in varying form factors) for home and industry applications.
