Tesla Powerwall 2 Battery
Tesla Energy Powerwall 2 is a 13.5 kWh battery that stores electricity generated from solar panels or the utility grid. Powerwall stores DC electricity (Direct Current) that must be converted to AC (Alternating Current) for use in the home.
According to Tesla, the Powerwall 2 battery can power a two-bedroom home for a full day. With a built-in inverter, installation can be either indoor or outdoor. Several additional products are required to operate Powerwall 2; however, Tesla has not provided any specification details about these parts or the inverter. Since Tesla has a limited track record of producing an inverter, a healthy dose of skepticism is in order. Previously, an inverter was required for each Powerwall; Two Powerwalls requires two inverters. The Powerwall must be installed by a Tesla Energy Certified Installer.
