Tesla Powerwall 2


Tesla Powerwall 2 is the most installed home battery in Australia for good reason. Aside from the almost cult-like following of the founder of Tesla, Elon Musk, the Powerwall 2 is a great product.

Is the Powerwall 2 a good battery?

The Tesla Powerwall 2 is generally considered to be a high-quality and reliable home battery option. It has a storage capacity of 13.5 kWh, which is sufficient to power an average home (essential loads) for several hours in the event of a power outage. It can also be integrated with solar panels to allow homeowners to store excess solar energy generated during the day and use it at night or during periods of high energy demand.

The Powerwall 2 is also designed with safety in mind and includes features such as thermal controls, fuses, and a liquid-cooled system to prevent overheating. It also comes with a 10-year warranty, which provides peace of mind to homeowners.

Overall, the Tesla Powerwall 2 is a good choice for those looking for a reliable and high-quality home battery option.

What are the Pro’s and Con’s of the Tesla Powerwall 2?


  1. Simple retrofit: The Popwerwall 2 can be added to most solar installations.

  2. Backup Power: The Powerwall 2 can provide backup power in the event of a power outage, allowing homeowners to maintain critical systems like refrigeration, lighting, and communication.

  3. High Capacity: With a storage capacity of 13.5 kWh, the Powerwall 2 can provide ample power for most households.

  4. Sleek Design: The Powerwall 2 is designed to be compact and aesthetically pleasing, so it can be installed in a variety of settings without detracting from the home’s appearance.

  5. Warranty: The Powerwall 2 comes with a 10-year warranty, which provides peace of mind to homeowners.


  1. AC coupled: AC Coupled batteries make them easy to add to most solar systems but there is a bit of double handling which results in a minor loss. The solar system produces DC, a standard solar inverter then converts it to AC power so you can use it. An AC-coupled battery then converts this energy back to DC to store it in the battery and back to AC again so it can be used.

  2. Grid restrictions: If you have maxed out your inverter capacity with standard solar inverters (or want to in the future) some grid providers might add restrictions for AC coupled battery solutions as they contain an inverter. E.g. if you have single phase in Queensland and you already have 10kW of solar inverter capacity and you want to add a Tesla Powerwall 2 your export maybe limited to 1.5kW from the standard 5kW allowance.

  3. Single phase backup: The product can be installed on three phase properties but backup will only be for single phase appliances. This is only a minor disadvantage because the reality is that in backup mode we typically only backup essential single phase loads because larger three phase loads drain the battery too quickly. Unless you are installing a very large bank of batteries single phase backup is adequate for most households.
