System Design & Specifications for SPAN Panels

  • Updated

Do SPAN Panels replace my existing electrical panel?

SPAN Panels replace your existing electrical panel to become the central energy management system for your home. SPAN Products are controllable via the SPAN Home App.

Is SPAN a good match for my new construction or retrofit project?

SPAN Panels are designed for installation flexibility and work well for both new homes and retrofit projects.

For new construction, SPAN Panels make it easier to enable clean energy homes regardless of whether the project includes solar and storage or simply paves the way for these improvements to be added in the future.

For retrofit projects, SPAN Panels enable cost-effective, streamlined solar and storage installations while delivering a completely differentiated experience for home energy control and customizable whole-home backup.

Are SPAN Panels serviceable?

All circuit breakers in SPAN Panels are serviceable by an electrician. A SPAN-authorized technician is required to service the internal assembly and internet-connected computer, though this is easily done without the need to remove the panel from the wall. Please contact your SPAN installer or SPAN Support if you require a service visit.

What breakers are compatible with SPAN?

SPAN is compatible with industry standard 1-inch breakers, both single and 2 pole, including Eaton, Siemens, and Square D, including tandem, quad, AFCI, GFCI styles.

A complete list of our compatible breakers can be accessed by SPAN-Authorized installers in our Tech Portal under our Panel Installation Guide (Appendix section). 

What can SPAN do for me and my home?
  • Customizable Battery Backup
  • Backup Time Remaining Estimates
  • Real-time Load Control
  • Energy Monitoring & Insights
  • Load Management for Upgrade Avoidance
  • Manage loads with PowerUp

Is PowerUp Code Compliant?

Yes. While approval for any residential electrical installation is ultimately up to local regulations, all versions of the National Electrical Code or “NEC” (NFPA-70) allow electrical services and distribution systems to be sized below the max ratings of all connected loads. While the newest NEC editions provide more focused language on this topic, all editions of the NEC in use across the US today provide an allowance for SPAN’s PowerUp energy management system (EMS), depending on the use case.
