Smart electrical panels (SPAN, Lumin, Schneider Square D Energy Center) manage circuit-level load dynamically — pause the EV charger when the dryer starts. Cost: $4,500 to $6,500 installed vs $1,500 to $2,500 for a traditional 200A panel upgrade. The premium pays back through avoiding service upgrade to 400A. Best fit for homes with heat pump + EV charger + induction + electric water heater all installed.
Smart panel avoids 400A upgrade
All-electric home (heat pump + EV + induction + HPWH + dryer) can require 320 to 480A simultaneous draw if all run together. Traditional panel needs 400A service to safely handle.
Smart panel manages the same load on 200A service by sequencing circuits dynamically. The dryer pauses for 30 seconds when the EV charger ramps up. Net cost savings: $4,000 to $8,000 vs 400A upgrade.
Battery, solar, and backup integration
Smart panels integrate natively with home battery storage. During grid outage, the smart panel decides which circuits to power from the battery.
SPAN integrates with Tesla Powerwall, Enphase IQ Battery. Lumin works as overlay to existing battery systems. Both add $1,500 to $3,000 for battery-integration hardware.
