Tesla Powerwall 2 Battery 14kWh Product Specifications

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 no 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. LEARN WHAT IS THE PRICE FOR 14kWh TESLA POWERWALL 2.0?

Tesla Energy Powerwall Battery System Diagram

The combination of solar panels and the Tesla Energy Powerwall battery delivers grid-tied savings and battery backup in a simple to manage system. The Tesla Installation Manual states that Powerwall must be installed by a Tesla Energy Certified Installer. Contact Tesla for details. The Tesla Energy Powerwall system consists of the following components.

  • Solar Panels - The solar panels generate renewable energy to power the home, charge the battery, or send excess power back to the utility grid.
  • Hybrid Inverter - The hybrid on-grid and off-grid inverter manages battery and system energy, in addition to its traditional function as a DC solar power inverter. The StorEdge and Fronius Symo hybrid inverters are certified compatible with Tesla Powerwall.
  • Meter for battery integration and for production and consumption readings for Feed-in Limitation.
  • Auto Transformer Regulates DC and AC voltage and current.
  • 13.5 kWh Tesla Powerwall is for daily use to maximize self-consumption and emergency backup using high-efficiency DC coupled Li-On battery.
