Authorized Span Smart Panel installer serving Greater Cincinnati and Northern Kentucky. Replace your traditional breaker panel with an intelligent panel that monitors and controls every circuit, manages loads dynamically, and integrates seamlessly with EV charging and battery storage.
The Span Smart Panel replaces your existing main breaker panel. Same physical role, fundamentally different capabilities.
Individual circuit monitoring. Every circuit in your home is measured continuously. You know exactly how much energy each circuit is using, in real time, historical, and projected.
Individual circuit control. Through the Span app, you can turn any circuit on or off remotely. Forgot to turn off the basement lights? Toggle them from your phone. Want the kids' game room to shut off automatically at bedtime? Schedule it.
Dynamic load management. This is the feature that matters most for Cincinnati homes. Span continuously monitors your total electrical demand and can dynamically reduce or pause non-essential circuits when the home is approaching service capacity. This means you can often add EV chargers, battery storage, and other high-load equipment without upgrading your service.
Whole-home energy intelligence. Identify the biggest energy users in your home. See how usage changes by time of day, weather, season, occupancy. Make informed decisions about appliance replacement, behavior change, or solar sizing.
Battery and solar integration. Span integrates with home batteries (including Tesla Powerwall) and solar systems for unified energy management. Critical loads designation happens at the panel level rather than requiring a separate critical loads panel in many configurations.
EV charger integration. Span's PowerUp technology specifically supports EV charging. The system can dynamically allocate available capacity to EV charging in real time, maximizing charging speed when capacity is available and reducing it when household loads spike.
Span isn't the right answer for every home. It's the right answer when one or more of these is true:
This is the most common Span use case in Cincinnati. Your home has 150A or 200A service that's tight but not impossible. You want to add a Level 2 EV charger. A traditional electrician will tell you to upgrade to 400A. Span can often eliminate that requirement entirely by managing loads so the EV charger only draws full current when capacity is available.
For homeowners facing $5,000 to $15,000 service upgrade quotes, the Span panel often costs less than the upgrade and provides additional capability the upgrade doesn't.
Span integrates with home batteries to manage critical loads at the panel level. For Tesla Powerwall installations, Span can eliminate the need for a separate critical loads panel in many configurations. The whole panel becomes intelligent backup management.
If you've ever wondered where your electric bill comes from, Span answers that question down to the individual circuit. For homeowners interested in efficiency, behavior change, or planning solar, this data is genuinely useful.
If you're doing a major renovation or new construction anyway, the cost premium for Span over a traditional panel is much smaller because the labor cost is spread across the larger project. New construction is the easiest time to install Span.
For homeowners building out smart home systems, Span integrates with the broader smart home ecosystem and serves as a foundational layer. Lighting, HVAC, security, and energy systems all benefit from circuit-level intelligence.
Honest pushback. Span is expensive compared to traditional panels. It's not the right answer when:
For homeowners in those situations, a traditional panel upgrade or repair is the right call. We tell customers honestly when Span doesn't fit.
A traditional 200A or 400A service upgrade gives you more capacity but no intelligence, no monitoring, no load management. Pure capacity addition.
A Span panel gives you intelligent management of existing capacity, often eliminating the need for a service upgrade. Plus monitoring, control, and integration capabilities.
For homes that primarily need more capacity, traditional upgrade is often the right answer. For homes that need to fit modern loads into existing capacity, Span is often better.
Several manufacturers (Eaton, Leviton, Square D) offer "smart breakers" that retrofit into existing panels and provide individual circuit monitoring and control.
Smart breakers are less expensive than Span and can be added incrementally. They don't provide the dynamic load management capability that's Span's signature feature, and they typically don't integrate as deeply with battery and EV systems.
For homeowners who want monitoring and control but don't need load management or deep integration, smart breakers are a credible alternative.
Devices like the DCC-9 or the Wallbox Pulsar Plus with energy management can manage EV charging loads against existing service capacity. Less expensive than Span and serve a narrower use case.
If your only goal is adding EV charging without a service upgrade, an energy management device might be sufficient. If you want broader monitoring, control, and integration, Span is the more complete solution.
A Span installation is a panel replacement, similar in scope to a traditional panel upgrade with additional configuration steps:
Span Smart Panel installations are quoted individually. Total cost depends on existing panel size and condition, Span panel size selection (32, 40, or 50-circuit configurations), service entrance condition, installation complexity, and any related electrical work (grounding upgrades, service modifications).
The Span panel hardware itself costs more than a traditional panel. The total installed cost is typically comparable to or less than a full service upgrade, often with significantly more capability included.
For homeowners considering a service upgrade specifically to enable EV charging or battery storage, Span often provides the same outcome at lower total cost.
Span's installer authorization process ensures installers have completed Span's training program, demonstrated technical capability, have access to Span's design tools and configuration support, and maintain ongoing certification compliance.
Working with an authorized installer ensures the system is configured correctly, the warranty is valid, and you have access to manufacturer support through the proper channels.

In most cases, yes. Span's load management dynamically allocates available capacity to high-draw circuits like EV chargers when other loads aren't running. This often eliminates the need for service upgrades that traditional electricians would otherwise require. The honest exception: homes that are already at or over capacity even without an EV charger. Span can't manufacture capacity that doesn't exist. A home running near its service ceiling 24/7 still needs a service upgrade.
Yes. Span integrates with Tesla Powerwall and other major home battery systems. For Powerwall installations, Span can manage critical loads at the panel level, often eliminating the need for a separate critical loads panel.
Yes. Span integrates with solar inverters from major manufacturers and provides unified monitoring of solar production, battery storage, and home consumption.
Typical Span installations are completed in 1 to 2 days of on-site work, plus permit and Duke Energy coordination. Configuration and customer training adds time but is part of the installation.
Yes. Span uses your home's WiFi for the app interface, software updates, and load management. The panel continues to function as a panel without internet, but the smart features require connectivity.
The panel continues to function as a basic electrical panel even if the smart components have issues. Power distribution and circuit protection don't depend on the smart features being operational.
No. Span replaces the panel entirely. There are smart breaker products that retrofit into existing panels (different products from Span) if you want monitoring without panel replacement.
Span provides a manufacturer warranty on the panel itself. Our installation work is covered separately by our workmanship warranty.
Span installations are typically scheduled 4 to 6 weeks out depending on equipment availability, permit timelines, and Duke Energy coordination. We provide specific timing during the estimate.
