Tesla Powerwall with Existing Solar

tesla powerwall


The customer wanted a battery storage system to use more of his solar, and buy less power from the grid. He liked the idea of having some backup ability as well, but this wasn’t a necessity.

Site Considerations:

System needed to retrofit to his existing SMA solar array, and be installed outside along a protected service wall.

System Design: 

  • SMA Sunny Boy Storage 2.5
  • 7kWh Tesla Powerwall
  • SMA Sunny Portal monitoring
  • Existing 7kW solar array
