At CES this week, Savant Systems announced Savant Smart Budget, a feature of its Smart Power system of modular relays and equipment that integrates with your existing circuit breaker box.

If you’re already at the limits of your breaker box’s capacity, Smart Budget lets you get around that with automated control of individual circuits. That way, you can add more high-draw connections, like appliances or EV chargers, than your electrical box can supply at once. For instance, you could set it so that power only goes to your EV overnight after you’re done using your oven. That sort of control can also be useful if you’re using a house battery or running on solar power.

Savant says its system, which starts at $1,500 and requires installation by a licensed electrician, is more affordable than the alternative of working with your electric utility provider to upgrade to higher amperage service, which “could cost in the tens of thousands of dollars.”

Those parts fit into “most major electrical panels” that “standardize on 1” breaker spacing,” company CMO J.C. Murphy tells The Verge, including panels from Schneider, Eaton, GE, ABB, Siemens, and others.

The Smart Budget kit will include two 30-amp single-pole circuit breakers, which Savant calls “Power Modules,” along with a double-pole 60-amp one and a current tracker for circuits you only want to monitor, according to Murphy. It also includes a Savant “Director” hub and sensors. The company sells additional Power Modules that cost $120 for dual 20-amp or single-pole 30-amp versions and $240 for a 60-amp double-pole module.
