Tesla Powerwall Storage Battery Gets Upgraded

Tesla Powerwall Storage Battery Gets Upgraded

The brand of Tesla Inc. has already proven its products’ high quality and reliability to the customers. If you want to buy Tesla Powerwall, my article is a good chance for you to learn about this product from an independent source. But first, let me speak a few words about the storage battery itself. A storage battery is installed and utilized to store the extra energy that the solar energy consumers often have. During the daytime, the solar system often generates too much power, and your house energy requirements don’t manage to cover its use. Due to the power storage battery, this energy can be kept for later use. You can use it either at night, when your solar system cannot produce energy, or whenever a power outage occurs. You can also transfer this energy to the local power grid and get compensation for it.

Tesla Powerwall

The device manufactured by Elon Musk’s team is designed and intended to be exploited as energy storage. Whether for residential or commercial purposes, this storage battery is ultra-convenient. The initial steps of development started in 2012 with incredibly successful results. In 2015 the same company launched the production of two devices straight off. The one with 10kWh capacity was intended for backup applications, the other with 7kWh capacity – for daily cycle applications. In time reducing the first device production with 10kWh capacity, the Tesla team concentrated on the 7kWh capacity device production. The Generation 2 Tesla Powerwall specs proved to be more relevant due to its curved design and features. Thus, by 2020 the company had already crossed the 100,000th installation line. To be more precise, it has similar features as the Generation 1 battery but with easier installation and setup. It is also aesthetically more convenient since it has a compact size. Even if two and more devices are installed side by side, the interior view is not spoiled all in all. Another advantage of the Generation 2 battery is that it has an integrated DC/AC converter, unlike Generation 1 energy storage device. With a slick design and varying styles, this device is suitable both for indoor and outdoor installation.

The cost for a Tesla Powerwall ranges between $5,000 – $7,000, not counting the additional price for associated supporting components and installation. The total cost also depends on your daily energy consumption requirements. Hence, on average, one storage battery is sufficient for a residential photovoltaic system consisting of 10-12 solar panels. However, if you decide to buy two or three power batteries for additional support, this will double or triple your expenses. 

The Tesla Powerwall capacity is not limited only to power backup. It provides excellent real-time energy monitoring services due to the app available for remote control. This means you can easily control your house alarm system, as well as energy consumption details away from your place. Thus, you can get the most out of your power system by counting the convenient and beneficial time your house electrical appliances use. The Tesla Powerwall warranty is one of the most suitable ones. With a 10-year duration, this device is sure to serve you far beyond the mentioned period on proper maintenance conditions.

Partnership With Home Depot

For further expansion of its products’ sale, Tesla Inc. launched a partnership with Home Depot in 2018. This was another big step that ensured a leading role for power storage batteries and other products of the company, such as solar panels, solar shingles, EVs, and related attributes. Hence, cooperating with Home Depo Tesla Powerwall strengthened its positions in the modern solar energy market. This partnership provided the opportunity to demonstrate different Tesla products in about 800 stores all over the country. With specialists’ consultation available for all the customers, the company registered high production and sale scores. However, later the CEO Elon Musk announced the company would not prolong its agreement with Home Depot. All the employees who worked at Home Depot would continue working in the stores of Tesla Inc.

Tesla Powerwall Specifications’ Upgrade


Just like many other electrical monitoring devices of the 21st century, the Tesla solar battery has undergone a series of software updates throughout the last years. Thus, for instance.

In 2017 Tesla improved overall efficiency at low power levels for versions 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 1.10. It also added the platform of Powerwall Self Registration for the consumers to visit and register after installation. The team added the capability of resetting the Powerwall and enhanced the support for off-grid and offline cases. Minor fixes and improvements permanently accompanied all the updates.

In 2018 over-the-air update performance was improved for version 1.11. For versions 1.12, 1.14, 1.15, 1.16, 1.17, 1.18, 1.19, 1.20, 1.21, 1.22, 1.23, 1.24, 1.25, 1.26, 1.27, 1.28, 1.29, 1.30 faster recharging was available, as well as automatic performance of preventative maintenance upon thermal control system. A storm watch mode activation also became available. Due to this function the device could already detect the incoming storms and store energy. Version 1.21 added monitoring from home network option to update network settings, monitor power flow and control system overall performance.

In 2019 versions 1.30, 1.31, 1.32, 1.33, 1.34, 1.35, 1.36, 1.37, 1.38, 1.39, 1.40, 1.41, 1.42, 1.43 received updates for utility grid connection support in areas like Zimbabwe, Switzerland, Western Australia, Dominican Republic. All historical data became available for downloading, reading, and sharing, thus improving communication with the Tesla Support team. They revealed a more user-friendly and flexible display for customers to simplify the maintenance process.

In 2020 versions 1.44, 1.45, 1.46, 1.47, 1.48, 1.49, 1.50, 20.40 received updates for additional system support in backup. The Tesla team added support for utility grid connections in Italy, Japan, South Africa and Cape Town. Solar roof owners got the opportunity to view the solar roof via the Tesla app home screen display.

In 2021 version 20.49 updated support for utility connections in Japan, Germany, Switzerland, and Italy.

As a matter of fact, despite all the above-mentioned software updates and innovative solution integrations, the Tesla Powerwall price has not undergone significant changes.
