How it works

Built around how your home uses power

The battery charges from the grid when power is on, then runs your essential circuits when the grid goes down. There are no panels, so it does not lower your daytime electricity use. It is purely about staying powered.

Included in this type of system

  • Hybrid inverter
  • Lithium battery

Why it works

  • Lower cost than a full solar system
  • No or minimal roof work
  • Silent, instant backup, no generator, no fuel
  • Add solar panels later to start saving

What to consider

  • Does not reduce your electricity bill on its own
  • Battery recharges from the grid, not the sun
