Powerwall 2

Powerwall is a home battery that can store electricity that you can use on demand to power your home and reduce your reliance on the grid. With Powerwall you can save money and live a clean energy lifestyle.


Powerwall 2 can be charged up by a solar PV system or is intelligent enough to charge up based on the time and price of energy, which will reduce your electricity bill without you doing anything.


Backup Gateway 2




Smaller (30%) and lighter (40%) than the previous version, the Backup Gateway 2 provides energy management, time based controls to the Powerwall and can also allows the owners to monitor the Powerwall via the Tesla Mobile app.


The biggest and possibly the most anticipated update to the Gateway to is the addition of backup capabilities to the Powerwall battery system. The Gateway 2 is the brain and essentially controls the Powerwall 2, with the Gateway 2 the Powerwall can detect an outage from the grid over 100x faster than a typical standby generator. It is so fast it can keep your appliances running without any interruption. This is called an Uninterrupted Power Supply (UPS), you wouldn’t even notice that the grid had an outage and your Powerwall would keep your home or business running as normal. Powerwalls can also be stacked meaning your backup power supply could be as large or small as you need it to be.


The Powerwall provides 13.5kWh of capacity and you can use this for either a whole home backup or an essential load backup. Whole load backup will backup your entire home and all appliances, while essential load backup will only keep the appliances which are essential to you backed up by the Powerwall.


The Gateway 2 connects to your WiFi network or via an ethernet cable, it can also have a cellular connection for a backup connection. This new data connection provides the Powerwall with a way to communicate from and to the owner’s smartphone app.
