Ground Zero Electric is an authorized Span installer serving Greater Cincinnati and Northern Kentucky. The Span smart electrical panel replaces your traditional breaker box with an intelligent energy hub that gives you real-time visibility and control over every circuit in your home from your phone.
If you're upgrading your panel, adding an EV charger, installing battery storage, or planning a renovation, Span is the panel that makes your home ready for all of it. One install. No revisiting the panel later.
A traditional electrical panel is a steel box with circuit breakers. It does one thing: distribute power. You interact with it when something trips, and that's about it. You have no idea which circuits are drawing the most power, no way to control them remotely, and no ability to prioritize loads during an outage.
Span replaces that entire panel with a smart system. Every circuit gets its own sensor and relay, giving you real-time data on what's using power and the ability to turn any circuit on or off from the Span Home app. During an outage with battery backup, Span dynamically manages your loads so your battery lasts longer, without you touching anything.

| Energy Monitoring | Traditional: none. Span: real-time, circuit-level data on every circuit in the home. |
| Remote Control | Traditional: must physically flip breakers at the panel. Span: on/off control from your phone anywhere. |
| Battery Backup | Traditional: requires a separate backup loads subpanel, decisions hardwired at install. Span: whole-home backup, priorities adjustable anytime through the app. |
| Adding Appliances | Traditional: may require a utility service upgrade ($5,000-$20,000+). Span: PowerUp technology manages loads to avoid the upgrade. |
| Data & Insights | Traditional: none. Span: detailed usage data to help reduce your energy bill. |
The Span panel unit itself runs around $3,500-$4,500 depending on configuration. With installation, total project cost is typically $8,000-$12,000+ depending on complexity, existing wiring condition, and any additional work needed. Contact us for an estimate specific to your home.
If you're adding battery storage, solar, or an EV charger, yes. A standard panel upgrade plus a separate backup loads subpanel can cost $2,000-$4,000 on top of the panel itself. Span eliminates the subpanel entirely and adds energy monitoring, remote control, and PowerUp load management. The gap narrows quickly when you factor in the work Span replaces.
Yes. Span is designed as a direct replacement for your existing 200A panel. It uses standard circuit breakers from major manufacturers, so your existing circuits transfer over. If your home requires more than 200A service or has more than 32 circuits, multiple Span panels can be installed.
Yes. Even without solar or battery storage, you still get circuit-level monitoring, remote control, energy usage insights, and PowerUp load management. Many homeowners install Span now and add solar or battery later.
When paired with a battery (like Tesla Powerwall), Span dynamically manages which circuits draw power during an outage. Instead of hardwiring a few circuits to a backup subpanel at install time, Span backs up your entire home and lets you adjust priorities on the fly through the app. Span claims this can extend battery life by up to 40% during outages compared to a traditional backup setup.
PowerUp is Span's load management technology. It lets you add high-draw appliances (EV chargers, heat pumps, induction cooktops) to your home without upgrading your utility service. Span monitors total load in real time and temporarily reduces power to lower-priority circuits when multiple high-draw appliances run at the same time. You set the priorities. Span handles the rest.
Yes. Span uses standard circuit breakers from major manufacturers. Any licensed electrician can service the breakers and circuits inside the panel. The smart features (app, monitoring, load management) are managed through Span's software and don't require special tools for routine electrical work.
Most Span panel installations are completed in one day, typically 4-8 hours depending on the number of circuits and complexity of your existing wiring. Your power will be off for a portion of the work, similar to any panel upgrade.
Schedule a site assessment to see if Span is the right fit for your home. We'll evaluate your current panel, discuss your energy goals, and provide a detailed estimate.
