Tesla Powerwall Backup Gateway

Uninterruptible Power Supply

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.
