Battery Storage

For Battery Storage solutions, Class A Energy Solutions work alongside industry-leading brands such as Tesla, Redback Technologies, and LG Chem. For stand alone, off-grid systems, we work with Giant Power.

Tesla’s Powerwall is a home battery that charges using electricity generated from your solar system, and then powers your home in the evening (loadshifting). Powerwall enables you to maximize self-consumption of your solar power generation. Currently, SolarEdge StorEdge (for single phase) and Fronius Hybrid (for three phase) are the only inverters that are compatible with Tesla’s Powerwall.


Benefits of the Powerwall include;


  • 6.4kWh Li-ion battery (3.3kW power)
  • 10 year warranty
  • Single phase and three phase utility grid compatible
  • Rated for both indoor and outdoor installation
  • 100% depth of discharge
  • 92.5% round-trip DC efficiency


Class A Energy Solutions is a Powerwall Authorised Reseller.
