Battery Energy Storage

Solar produces the most power in the middle of the day, which is rarely when a household uses the most. Battery storage closes that gap, holding your excess production so it is available in the evening, during peak utility pricing, or when the grid goes down.

We install battery systems for new solar projects and retrofit them onto existing arrays. The design work matters here: we identify which circuits need to stay live during an outage, size the storage capacity to your critical loads, and configure the system so it switches over safely and automatically.

What’s included

  • Backup for your critical circuits during outages
  • Retrofit options for existing solar systems
  • Capacity sized to your real evening and peak loads
  • Automatic, safe transfer with no manual switching
  • Avoidance of peak rates where your utility offers it
  • Clean, ventilated installation that meets code

The result is a home or business that keeps essential systems running through an outage, and that uses more of the clean energy it generates instead of exporting it.
