Smart Energy Systems
Modern home energy management.
Sespe Power Solutions installs Span and Lumin smart panels for Ventura County homeowners who want circuit-level visibility, automated load shedding during outages, and a foundation for full electrification (heat pump HVAC, induction cooking, EV). A Span Panel typically runs $5,500–$8,500 installed as part of a solar + battery upgrade.
- Smart panel installs (Span, Lumin)
- Load shedding and EV/solar coordination
- Real-time circuit-level monitoring
- Foundation for future electrification (HVAC, induction)
A smart energy system gives you visibility and control over how every circuit in your home uses power — and lets your solar, battery, and EV work together intelligently. We install Span and Lumin smart panels and integrate them with your existing system.
What you get
- Real-time, circuit-level monitoring
- Automated load shedding during outages
- Smart prioritization of solar and battery output
- Future-ready for heat pump HVAC and induction cooking
- App-based scheduling and remote control
Frequently asked questions
What does a smart panel do?+
It replaces (Span) or augments (Lumin) your main service panel with circuit-level monitoring, app control, and automated load shedding during a battery-backed outage to extend runtime.
Span vs Lumin — which is better?+
Span replaces the whole panel and gives every circuit individual app control. Lumin sits next to the existing panel and controls 12 circuits — cheaper and faster to install but less granular.
Do I need a smart panel if I already have a battery?+
No, but it's the easiest way to make a small battery feel like a big one. By shedding loads automatically, a 13.5 kWh Powerwall 3 + smart panel can outlast a 20+ kWh battery without one.
Will a smart panel let me add a heat pump or induction range later?+
Yes — that's one of the main reasons to install one. Smart panels manage your service capacity intelligently so you can add electric loads without a service upgrade.
How much does a Span panel cost installed?+
$5,500–$8,500 in Ventura County for a typical residential install, including permit and inspection.
