Overview
Span creates a smart electrical panel that serves as a centralized home energy hub. The SPAN Panel replaces a traditional breaker box and is controlled via the SPAN Home App to monitor and manage every circuit in real time. It works with solar panels, home batteries, and EV chargers, and its circuit-level controls help users identify and reduce energy use. In outages, it prioritizes essential circuits to extend battery life by about 40%, allowing homeowners to add new electric devices without costly utility upgrades. Span sells hardware through certified installers and partners with Sunrun and Kenmore, aiming to make homes more energy-efficient, resilient, and ready for full home electrification.
