Tesla Powerwall Backup Gateway

Uninterruptible Power Supply

Tesla have recently introduced backup power capability to its Tesla Powerwall. The new Backup Gateway 2 will allow the Powerwall 2 to have an uninterruptible power supply enabled. This will allow the Powerwall to provide power in the event of a power outage.

Traditionally a normal solar system will shut down in the event of a power outage to prevent any power going back into the grid. The Backup Gateway 2 uses clever technology to manage the grid connection and allow solar to continue to operate during an outage.

Powerwall is a home battery that stores solar energy so you can use it day or night and self-power your home. Solar panels typically generate more clean energy than your house can immediately use. Powerwall stores that excess solar to make it available on demand, maximising your use of solar and reducing your reliance on the grid. Through the Tesla mobile app, you gain full visibility and control over your self-powered home.

Compact and simple to install, Powerwall 2 is a completely automated system that requires no maintenance The Powerwall 2.0 has more than twice the energy storage capacity of the original version with 13.5 kWh capacity. Over double the capacity means double the ability to keep your home humming with guilt-free electric power.


  • Touch Safe - Touch safe for the entire family with no live wires or bulky vents.
  • Flexible Installation - Wall mounted or floor mounted, stack up to nine Powerwall units to power homes of any size.
  • Durable Design - Water resistant and dustproof enclosure for installation inside or outdoors.
  • Always Connected - Monitor your solar energy use in real-time and receive alerts when Powerwall is preparing for cloudy or severe weather.

Self-Powered home. Just add Powerwall.

Powerwall integrates with solar to store excess energy generated during the day and makes it available when you need it, minimising reliance on your utility.

Time-Based Control. A Smart Way to Use Energy.

If your utility prices vary throughout the day, set Powerwall in Time-Based Control to maximize savings. Powerwall learns patterns in your energy usage and solar generation—using stored energy to avoid purchasing high-cost electricity.

4 Other FAQ'S

What If I Don’t Have Solar Panels Installed?

To be eligible for the Tesla Energy Plan, you must have both solar panels and Powerwall 2 installed. To install solar panels, ideally you’ll need a minimum clear space of 24 square meters – about the size of a parking space – available on your roof. The area should be free of shading from trees, chimneys or other buildings for most of the day to get the maximum energy generation from your panels. A Tesla Energy Advisor or your local Tesla Powerwall Certified Installer can help assess system sizing and provide a quote on solar and Powerwall.

I Already Have Solar And Powerwall. What Is Next?

You can transfer onto the Tesla Energy Plan straight away by switching your retail plan. You need a smart meter in your home; however, Octopus can arrange to have one installed at no charge.

Do I Have To Own A Powerwall To Sign Up?

Yes, you must own a Powerwall 2 to sign up. The Tesla Energy Plan combines solar with Powerwall to maximise your savings. If your Powerwall installation is already scheduled, we will manage the tariff transfer process once your system is installed.
