A smart electrical panel is a circuit breaker panel that adds per-circuit monitoring and remote, app-based control to some or all of a home’s circuits, with installed prices running from about $2,500 for a monitoring-and-switching system up to $10,000 for a full replacement with automatic load management (checked September 2026). The pitch is real: see what every circuit draws, shed non-essential loads during an outage so a smaller battery or generator lasts longer, and sometimes skip a service upgrade when adding a load like an EV charger. Whether it earns its cost depends on which job you need, since two cheaper categories of hardware can cover parts of it on their own.
What a smart electrical panel actually does
A conventional panel is a dumb distribution block: breakers trip on overload or short circuit and that is the extent of their intelligence. A smart electrical panel adds two things on top of that: a current sensor on every breaker, or on the ones fitted with smart breakers, that reports real-time usage to an app, and a relay or contactor that can switch each circuit on or off remotely or on a schedule. Three systems are sold as full panel replacements: SPAN’s Smart Panel, Schneider Electric’s Square D Energy Center, and Leviton’s Smart Load Center. Eaton takes a different approach with its AbleEdge line, individual smart breakers that snap into an existing Eaton BR-series panel, so you upgrade circuit by circuit instead of replacing the whole box.
SPAN’s panel monitors and can individually switch every circuit from the SPAN Home app, in versions covering 16 to 48 circuits, and pairs with a home battery to change which rooms stay powered during an outage. Schneider’s Square D Energy Center works the same way but leans on dynamic load management: it can automatically pause or throttle selected circuits so the home’s total draw never exceeds what the service can safely carry. Leviton’s Smart Load Center covers up to 42 circuits with monitoring and remote on/off control through the My Leviton app once it is fitted with Leviton’s whole-home monitor and second-generation smart breakers.
Installed cost against a conventional panel
A standard 200A panel replacement with no smart features typically runs $1,500 to $3,000 installed, most of it electrician labor. Smart hardware adds a real premium, and how much depends on whether you are buying a monitoring layer or a full load-managing replacement:
| System | Type | What it controls | Typical cost |
|---|---|---|---|
| SPAN Smart Panel | Full panel replacement | Every circuit, individually switched | $2,550 hardware; $3,500-$10,000 installed |
| Schneider Square D Energy Center | Full panel replacement | Up to about 40 circuits, automatic load management | $5,000-$7,500 before installation |
| Leviton Smart Load Center | Full panel replacement | Up to 42 circuits, monitoring plus remote on/off | $2,500-$4,000 installed |
| Eaton AbleEdge smart breaker | Retrofit into an existing panel | One 240V circuit per breaker | $220-$320 per breaker plus labor |
| Emporia Vue 3 | Clamp-on monitor, no switching | Whole-home plus 8-16 branch circuits, monitoring only | $100-$200 hardware |
The spread inside each row is mostly labor and logistics: a straight panel swap in an accessible garage costs less than a job that also relocates a meter, adds a subpanel, or routes new wiring for the app’s cellular or Wi-Fi connection. Circuit count matters too, since a 48-circuit SPAN panel for a large house with two HVAC systems and a workshop costs more than a 16-circuit version for a condo.
Load shedding: making a smaller battery or generator go further
The clearest payoff shows up during an outage. Central air conditioning illustrates why: a compressor that draws roughly 3,000-4,000 running watts (see our breakdown of how many watts an air conditioner uses) can surge to three to five times that at startup, so 9,000-20,000W for a second or two. Most home battery inverters cap out well under that once everything else is running too, which is why battery systems are sized to cover a chosen set of circuits rather than the whole panel; see how those numbers add up in our whole-house battery cost breakdown.
A smart panel turns that circuit selection into something you can change later instead of hard-wiring it once at install. Say the circuits worth keeping alive are a refrigerator (roughly 150W running), a sump pump (800W running), a few LED lighting circuits and outlets (150W), and a Wi-Fi router and modem (20W), about 1,120W of continuous draw. On a 10,000Wh (10kWh) home battery, runtime works out to 10,000 x 0.85 / 1,120, or roughly 7.6 hours per full charge, with the 0.85 accounting for inverter loss. Add the air conditioner’s 3,500W running load to that same circuit list and the total becomes 10,000 x 0.85 / 4,620, about 1.8 hours, and the inverter may not survive the compressor’s startup surge at all. A smart panel lets you drop the AC, dryer and oven from the backup list with a tap instead of an electrician re-wiring the backup subpanel, then add them back once a generator can carry the load instead.
Avoiding a service upgrade for EV charging
Adding a Level 2 EV charger is the other common trigger. A charger rated for 32A of continuous draw needs a 40A breaker, because a continuous load is capped at 80% of the breaker’s rating, so a 40A breaker safely carries 32A x 240V, or 7,680W continuous, not the full 9,600W the breaker is rated for (run your own numbers with our watts-to-amps calculator). On an older 100A or 150A service already carrying an electric range, a dryer and central air, adding that load on paper can push the calculated total past what the service is allowed to carry, which has historically meant a service upgrade that electricians commonly price at $2,000-$4,500, sometimes more if the utility has to replace a transformer or run new service.
The 2020 and 2023 National Electrical Code added a way around that for panels with a certified energy management system: the code lets an electrician size the service based on what the system will actually allow to run at once, rather than the sum of every circuit’s nameplate rating. That is the feature Schneider and SPAN both sell as automatic or dynamic load management, and it can pause a water heater or EV charger for a few minutes while the oven and air conditioner are running, then resume once demand drops. It only works if the local building department has adopted the load-management provisions and the installer files the paperwork, so confirm that before assuming it will skip an upgrade. This is all work inside a live service panel, so it is a licensed electrician’s job, not a weekend project.
Everyday energy monitoring
Outside of outages and EV chargers, the daily use case is visibility: seeing which circuit is running up the bill, catching a refrigerator or well pump drawing more than it should, and lining up big loads with off-peak utility rates where those exist. That job is genuinely useful, and it is also the one thing the cheapest hardware already does well, which is worth knowing before paying for a full panel just to get it.
Cheaper alternatives: smart breakers and clamp-on monitors
If switching circuits from an app is not the point and watching usage is, a clamp-on monitor costs a fraction as much. Emporia’s Vue 3 fits current-sensing clamps around the main feed and, in its 8- or 16-circuit versions, around individual branch circuits, for $100 to $200 in hardware. It reports usage in a companion app but cannot turn anything off, and because it adds no switching relay, some owners have an electrician install the clamps in a few minutes during an unrelated visit rather than pay for a dedicated job.
If remote switching matters for one or two specific circuits, an EV charger, a water heater, a well pump, a smart breaker gets you that without a panel replacement. Eaton’s AbleEdge breakers, at $220 to $320 each, drop into an existing Eaton BR-series panel one circuit at a time and report to the Brightlayer Home app; Leviton sells its second-generation smart breakers the same way for panels already fitted with its whole-home monitor. Either approach can cover the EV-charging or single-appliance case for a few hundred dollars plus an hour of labor per breaker, well short of a full panel’s cost.
Whether it pays off
A full smart panel earns its cost when at least two of these apply: a home battery or whole-home generator is already going in and the backed-up circuits should be changeable later, an EV charger or other large load is going onto a service near its limit, or the panel needs replacing anyway and the smart version is a modest premium over a standard one. Buying one purely to watch a chart of daily usage is the expensive way to get there. A $100-$200 clamp-on monitor answers that question on its own, and a $220-$320 smart breaker on the one or two circuits that actually need remote control does most of what a $5,000-$10,000 panel does for the loads that matter, without paying to switch the ones that do not.
Frequently asked questions
Do I need a smart panel to add battery backup or a generator?
No. Most home battery systems and generator transfer switches work with a standard panel and a manual or automatic transfer switch chosen and wired at install. A smart panel is an upgrade that lets an owner change which circuits are backed up after the fact instead of committing to a fixed set of circuits during installation.
Does a smart panel lower an electric bill by itself?
Monitoring alone does not save money; it only shows where the money is going. Savings come from acting on it, such as fixing a phantom load or shifting a big appliance to an off-peak rate window, or from load management paired with solar and a battery.
Can a smart breaker or clamp-on monitor be installed without an electrician?
A clamp-on monitor’s sensors still go inside a live panel, and a smart breaker replaces an existing breaker, so both involve opening the panel even though neither is a full swap. Manufacturers sell them as licensed-electrician installs for exactly that reason, and working inside a panel is not a do-it-yourself job.
Will a smart panel work with any home battery or generator brand?
Compatibility varies by manufacturer and changes as product lines update, so confirm the specific pairing, panel model, inverter or battery brand, and transfer equipment, with an installer before buying either piece.
Is a 42-circuit smart panel enough for most houses?
Most single-family homes run 30 to 42 circuits on a 200A service, so a 42-circuit panel covers a typical house. Larger homes with two HVAC systems, a workshop, or an accessory dwelling unit may need one of the higher-circuit-count options instead.
