Discover the constraint
A contractor evaluates an electrification project and finds that the existing electrical capacity may not support the new load.
Retrofit-ready smart circuit breakers
Electrify the home.
Skip the panel upgrade.
Noble Carbon helps homes add EV chargers, heat pumps, and batteries without rebuilding their electrical infrastructure.

How Noble Carbon reaches the home
Built into the contractor’s existing decision
The opportunity appears when an electrician, EV installer, HVAC contractor, or storage installer discovers that a new load would push the home beyond its available capacity.
Offer a modular path
Instead of defaulting to a full panel or service upgrade, the contractor can address the circuits creating the constraint.
Return as the home electrifies
The system can expand circuit by circuit as the customer adds an EV charger, heat pump, battery, or other major load.
The constraint hiding in the basement
Millions of homes are ready to electrify. Their infrastructure isn’t
Adding an EV charger, heat pump, or battery can trigger thousands—or tens of thousands—of dollars in unexpected panel and service upgrades.
Projects become unaffordable. Contractors lose business. Electrification stalls.
50–60MU.S. single-family homes have electrical panels rated below 200 amps—and most will likely need load management or an upgrade to fully electrify.Source: Rewiring America ↗
Use the capacity already there
Turn a fixed electrical limit into flexible infrastructure
Noble Carbon puts intelligence and control at the circuit level—inside the panel already serving the home.
Upgrade selectively
Install smart breakers only on the circuits that need monitoring or control.
See demand in real time
Measure circuit-level energy use and understand how the home uses its capacity.
Coordinate flexible loads
Our commercial platform will automatically manage lower-priority loads as capacity changes.
A better path through the panel
Upgrade the intelligence—not the entire system
Rebuild the infrastructure
- Large upfront project
- More time and disruption
- Replace everything at once
Add another appliance box
- Usually dedicated to one load
- Separate hardware and wiring
- Limited circuit-level visibility
Make the existing panel smarter
- Retrofit-ready
- Modular by circuit
- Expands as the home electrifies

Built around the people doing the work
Turn constrained projects into completed projects
Noble Carbon is designed to fit the breaker-level workflow electricians already know—without turning an appliance installation into a full electrical rebuild.
For contractors & distributorsProof, clearly labeled
Built, advancing, and scaling
Hardware and software tested in real homes
We have tested working breakers, circuit-level monitoring, and software-connected control in our own homes for more than 18 months.
UL certification and a 200-home pilot
UL certification is pending alongside a public Eversource pilot funded by the Massachusetts Clean Energy Center.
A two-inch commercial breaker
The pilot uses the four-inch Quad. The planned commercial product moves the platform into a compact two-inch form factor.
