Leviton is the best value proposition for monitoring — $2,500–$4,000 for 42-circuit visibility and remote circuit toggling. The critical limitation: it cannot do active load management, which means it does NOT qualify for NEC 2026 service upgrade avoidance. If you're just adding solar and want to see where your energy goes, Leviton is excellent. If you need to avoid a service upgrade, look elsewhere.

Pending — Leviton Smart Load Center supports monitoring but lacks the active load manageme
✓ Traditional panel safety listing
Not Energy Star certified
Certification note: Leviton Smart Load Center is UL 67 listed. UL 3141 certification for the smart features was in process as of Q1 2026.
Ecosystem lock-in: Leviton lacks load CONTROL for third-party batteries and EVSEs — it cannot shed EV charging load automatically.

Combined worst case
This panel monitors loads but CANNOT manage them
The Leviton Smart Load Center gives you real-time circuit visibility, but it does not actively shed or throttle loads. Without active load management, your AHJ will require a utility service upgrade to accommodate high-draw additions like EV chargers or heat pumps.
Budget for Path A (service upgrade) in addition to your smart panel investment.
NEC 2026 Note: NEC 2026 Article 705 requires UL 3141 certification to qualify for load management service upgrade avoidance — the Smart Load Center's UL 3141 certification is pending, meaning AHJ approval is not yet guaranteed.

What gets shed during the outage
This panel can remotely shed circuits manually via app — but won't do it automatically during an outage.

How this is calculated: Battery hours = (battery kWh × 0.85) ÷ ((tier amps × 120V) ÷ 1,000). Assumes 120V average for residential circuits and 85% usable capacity. Average amp draw used for runtime (not peak). P3 shedding is immediate; P2 shedding triggers at 30% remaining capacity.

Load profiles are representative 24-hour patterns in amps at 240V residential service. Actual loads vary by home size, occupancy, climate, and specific appliances.
Shedding logic mirrors documented behavior: sheddable loads (dryer, EV charger, dishwasher) are deprioritized when load exceeds 80% of service capacity during peak-rate hours, or when battery SOC drops below 30%.
Peak rates shown are representative TOU schedules. Actual savings depend on your utility’s exact peak window, rate structure, and enrollment in a TOU plan.
Battery runtime is estimated from excess load above 25% of service capacity. Real runtime depends on battery chemistry, depth of discharge settings, and temperature.

A traditional breaker panel has no communication capability — no app, no monitoring, no control. Every check mark above represents a capability this panel adds over baseline. Tier scores are based on the panel’s documented feature set, not marketing claims.
Our engineers can advise on whether this panel is the right fit for your home's solar, battery, and EV setup.

If you're just adding solar and want to see where your energy goes, Leviton is excellent. If you need to avoid a service upgrade, look elsewhere.
No — the Leviton Smart Load Center does not provide active load management, which is required under NEC 2026 Article 705 for service upgrade avoidance. If adding an EV charger or heat pump to a 100–150A service, you will likely still need a service upgrade or should consider a UL 3141-certified alternative.
The Leviton Smart Load Center hardware costs $2,500–$4,000. As an add-on module, installation is typically simpler than a full panel replacement — expect $500–$1,200 in labor and permits. Total installed cost is approximately $3,000–$5,200.
For solar, it has native (first-party) integration with Enphase. Most other brands are compatible via standard grid interconnect. Note: Leviton lacks load CONTROL for third-party batteries and EVSEs — it cannot shed EV charging load automatically.
The Leviton Smart Load Center does not support direct battery integration, so it does not provide backup power during an outage on its own. For outage protection, you would need a compatible battery system paired with a panel that supports battery integration.
Yes — the Leviton Smart Load Center supports EV charger integration. If you are adding an EV charger, the Section 30C federal tax credit is active through June 30, 2026 and covers 30% of EV charger hardware and installation costs (up to $1,000 for residential installations).
