Span Smart Electrical Panel
The Span Smart Electrical Panel brings unprecedented circuit-level insight and remote control to modern homes, making it a standout upgrade for battery systems despite an involved installation.
Pros
- + Granular real-time power monitoring and remote control across 32 individual circuits
- + Automated load shedding and circuit prioritization when paired with home battery storage
- + Built-in color display provides instant real-time energy flow status at the panel
- + Supports standard 1-inch residential breakers
Cons
- − Requires full panel replacement with a 4-to-8-hour home power outage
- − Large physical footprint (49 by 17 inches) may present installation constraints
- − Requires professional installation by an electrician or certified installer
The Span Smart Electrical Panel aims to modernize residential power infrastructure by replacing standard, passive breaker boxes with an intelligent, cloud-connected hub. Built for energy-conscious households, it elevates standard home electrical management by offering remote switching and real-time monitoring across individual circuits via a companion mobile app or its integrated color display.
The system is particularly compelling for homes running or planning battery storage. By dynamically shedding loads and managing circuit priorities during utility outages or high-rate pricing windows, it automates what has traditionally been an awkward, manual chore during a blackout.

Span succeeds at delivering deep, actionable energy orchestration. With 32 controllable circuits and compatibility with standard 1-inch residential breakers, it offers flexible capacity without locking users into a proprietary breaker format. The combination of Wi-Fi connectivity and physical real-time readouts gives homeowners immediate transparency into where their power goes.
However, the transition requires a serious commitment. Because it entirely replaces the existing panel rather than piggybacking onto it, installation demands certified professional labor and leaves the home without power for four to eight hours. At 49 by 17 inches, its substantial footprint may also pose spatial challenges in cramped utility spaces. Nonetheless, for homeowners seeking to maximize battery efficiency and automate home energy management, Span represents a premier smart upgrade.
