The short answer: Span Smart Panel ($3,500 hardware, $6,500–10,000 installed) — 32 controllable circuits, best backup management, deepest battery integration.
Your electrical panel is probably the most boring thing in your house. It sits in the garage, you open it once a year to flip a tripped breaker, and that's about it. Smart panels want to change that — and honestly, for homes with solar, batteries, and an EV charger, they actually deliver. The Span Smart Panel is the one most experts agree on. EnergySage calls it "the most comprehensive home energy management solution available," and 8MSolar rates it their top pick for solar and battery homeowners. These things aren't cheap — you're looking at $6,500–12,000 installed — but they replace the need for a separate critical load subpanel and give you real-time control over every breaker from your phone.
We don't test products — we aggregate what experts say. We pulled assessments from EnergySage, 8MSolar, SolarTechOnline, ProBuilder, and SolarReviews, weighing installation experience, solar/battery integration depth, app quality, and backup flexibility. Prices verified April 2026. For the full home energy picture, pair your smart panel with our best whole-home energy monitors guide and our smart home energy audit guide.
Best Overall: Span Smart Panel 200A
Span Smart Panel 200A
(Current Price, subject to change)
The Span Smart Panel is basically what happens when a Silicon Valley startup looks at the 60-year-old electrical panel in your garage and says "we can do better." And they did: 32 individually switchable circuits, real-time energy monitoring on each one, and full control from your phone whether you're in the kitchen or on vacation. 8MSolar gave it the highest marks of any smart panel for solar and battery integration, and the expert consensus backs that up.
Here's the killer feature for battery homes: Span eliminates the critical load subpanel entirely. Traditional battery setups (think Tesla Powerwall or Enphase IQ) require a separate subpanel wired to back up only certain circuits during outages. With Span, you just designate backup priority in the app. When the grid goes down, Span automatically sheds lower-priority loads to stretch your battery runtime up to 40% longer than traditional subpanel setups, per Span's testing.
It works with every major residential battery: Tesla Powerwall 3, FranklinWH aPower, Enphase IQ Battery 5P, LG Chem RESU, SolarEdge Energy Bank, and Generac PWRcell. For EV charging, the app talks directly to Level 2 smart chargers so you can schedule charging during off-peak rates or when your solar panels are cranking. Your existing 1-inch breakers work inside it, too.
Installation runs 6–8 hours with a licensed electrician. The 4G/LTE cellular backup keeps the panel controllable even when an outage takes out your router — a nice touch that the other panels mostly lack.
Worth noting: Span announced a $75 million partnership with Eaton in March 2026, which should expand their installer network and potentially bring down installation costs over time. That's still developing, but it signals Span isn't going anywhere.
What We Love
- 32 individually controllable circuits — finest-grained control in any mainstream smart panel
- No critical load subpanel needed — simplifies battery installation dramatically
- Compatible with all major batteries — Powerwall, Enphase, FranklinWH, LG, SolarEdge
- 4G/LTE cellular backup — stays connected during outages (no router required)
- 40% longer backup duration — smart load shedding extends battery life versus traditional setups
- 10-year warranty — longest in the category
What Could Be Better
- $3,500 hardware is 10x the cost of a traditional 200A panel ($300–400)
- $6,500–10,000 installed is a significant upfront investment
- 32 circuits max per panel — very large homes may need a second panel
- Requires professional installation — not a DIY project
- Cellular subscription (4G/LTE backup) has ongoing costs after the first year
Is the Span Smart Panel 200A worth buying in 2026?
If you're already dropping $15,000–25,000 on solar panels and a battery storage system, adding $3,500 for the Span Smart Panel is where the math starts making sense. Killing the critical load subpanel saves you $1,500–3,000 in labor and materials right there, which offsets a big chunk of the cost. Without solar or battery? Harder to justify. The Leviton retrofit breakers or Savant modular system might be all you need at a lower price.
"The Span Smart Panel is the most comprehensive home energy management solution available — it replaces both your main panel and critical load subpanel in one device, with the best battery integration we've tested." — EnergySage
Does the Span Panel qualify for the 25C tax credit?
This one's complicated. The IRS 25C credit covered up to $600 (30% of costs) for qualifying panel upgrades — but you had to pair it with a heat pump or similar efficient appliance, and the 2025 deadline has passed. For 2026 installations, the status depends on pending legislation, so talk to a tax advisor before counting on it. The good news: Span panels often qualify for utility rebate programs too. Check the DSIRE database for your state — those rebates are independent of federal credits.
The Verdict
The Span Smart Panel 200A is the best smart panel for solar and battery homes — it eliminates the critical load subpanel, stretches battery runtime by 40%, and gives you the finest-grained circuit control in any residential panel. If you're investing in solar and storage, this is where the math works.
Can the Span Panel handle a large home?
Yep. If 32 circuits isn't enough (typical large homes run 32–48), you can install two Span panels in parallel. The app manages both from a single interface. Most homes under 3,500 sq ft are fine with one 200A panel. And if you just need a few more slots, the MAIN 40+MID model (reviewed below) gives you 40 circuit positions without doubling up.
Best for New Builds: Span Panel MAIN 40+MID
Span Panel MAIN 40+MID
(Current Price, subject to change)
The Span Panel MAIN 40+MID exists because homebuilders and solar installers kept asking for more circuits and simpler solar hookups. Announced at IBS 2025 and shipping since April 2025, it adds 25% more breaker spaces than the original and bakes in a Microgrid Interconnection Device (MID) — that's the thing that normally gets installed as a separate box to connect your solar and batteries to the home grid.
That built-in MID saves real money. A standalone MID usually adds $800–2,500 in equipment and labor. Span says builders can save up to $10,000 per home when you add up the MID elimination, no critical load subpanel, and simpler wiring overall. If you're a production homebuilder running all-electric specs, those numbers add up fast.
The 40-circuit capacity handles today's all-electric homes — heat pumps, heat pump water heater, two EV chargers, solar + battery — without running out of slots. Same battery compatibility and same Span app as the original for circuit-level control and backup management.
What We Love
- 40 circuit positions — 25% more capacity than original Span, handles large all-electric homes
- Built-in MID — eliminates separate microgrid interconnection device ($800–2,500 savings)
- Up to $10,000 builder savings — fewer components, simpler installation for new construction
- PowerUp software — enables load management that avoids 400A service upgrades
- Same Span app and ecosystem — all the original panel's intelligence, more circuits
What Could Be Better
- Higher hardware cost (~$4,200 vs ~$3,500 for original Span)
- Newer product — less field installation data than the original Span
- Primarily designed for new builds, not retrofits (the built-in MID is less useful as a retrofit)
- Still requires professional installation
Is the Span Panel MAIN 40+MID worth it over the standard Span?
If you're building new or doing a full solar + battery install from scratch, yes — the MAIN 40+MID actually saves money overall despite the higher sticker price because you skip the separate MID box. If your home already has solar and you're just upgrading the panel, the original Span 200A is the simpler, cheaper, more field-tested choice. Think of the MAIN 40+MID as the "doing everything at once" panel — new build, new solar, new battery, 40+ circuits.
The Verdict
The Span MAIN 40+MID is the right panel if you're building new with solar and battery from day one. The built-in MID saves real money on components and labor, and 40 circuits handles today's all-electric homes without running out of slots.
"The SPAN Panel MAIN 40+MID with built-in MID simplifies solar and battery integration like nothing else on the market for new builds — builders can save up to $10,000 per home versus conventional panel setups." — SolarBuilder Magazine
Best Utility-Brand: Schneider Electric Pulse 200A
Schneider Electric Pulse 200A
(Current Price, subject to change)
The Schneider Electric Pulse is what happens when one of the world's biggest electrical equipment companies finally builds a smart panel. It's built on Square D — the brand that's literally wired more than half of American homes — so your electrician probably already knows the platform. EnergySage notes it's "particularly well-suited for homes with existing Schneider/Square D equipment," which is a nice way of saying your electrician won't charge extra to figure it out.
At 46 circuit positions, the Pulse has the most capacity of anything in this roundup — 14 more than the Span 200A, 6 more than the Span MAIN 40. If you have a big house and don't want to install two panels, this is your pick. The Wiser Energy system extends monitoring to individual circuits with add-on current transformers, and the Schneider Home app handles per-circuit on/off control with real-time energy data.
For solar and battery, you'll want the Backup Control Module version (CC18X18M200PCZ), which adds battery management and automated load shedding during outages. The Pulse plays especially well with SolarEdge inverters thanks to a formal Schneider/SolarEdge partnership, and it supports other battery systems through standard protocols. The honest tradeoff: the app isn't as slick as Span's, and battery brand support is narrower.
Schneider also launched the Square D QO Smart Panel Solution in February 2025 — a software layer that handles load management without a 400A service upgrade, potentially saving builders up to $17,000 per home.
What We Love
- 46 circuits — most capacity in a single smart panel enclosure
- Square D reliability — the most electrician-trusted brand in residential panels
- Wiser Energy ecosystem — extends to whole-home monitoring and control
- SolarEdge integration — formal partnership for optimized solar management
- Familiar to electricians — may reduce installation labor costs
What Could Be Better
- App and software less polished than Span's mobile-first design
- Backup Control Module required for full battery integration (additional cost)
- Fewer compatible battery systems than Span (Span supports more brands officially)
- Less field-proven at the consumer level than Span's original panel
Is the Schneider Electric Pulse worth buying in 2026?
If your electrician already works with Square D and you need more than 40 circuits, the Schneider Pulse is the obvious choice. The 46-circuit capacity is genuinely hard to beat. And if you're going with SolarEdge solar, the Schneider partnership makes that integration smoother than anything else. But if you care most about the app experience and the widest battery compatibility, the Span panel still wins. This is a "know your priorities" decision.
The Verdict
The Schneider Pulse earns its spot for large homes and SolarEdge households — 46 circuits at a lower hardware cost than Span, backed by the most electrician-trusted brand in residential panels. If your electrician already works with Square D, this is the path of least resistance.
"Schneider Electric brings industrial-grade reliability to the smart panel category — the Pulse's 46-circuit capacity and Square D build quality make it the most electrician-trusted option in the market." — SolarTechOnline
Best Retrofit (Budget): Leviton 2nd Gen Smart Circuit Breakers {#leviton}
Price: $141–257 per breaker on Amazon (full panel: $2,800–5,000+ installed depending on circuit count)
What's Included:
- Individual 2nd Gen Smart Circuit Breakers (1-pole and 2-pole options, 15A–60A range)
- Leviton Load Center compatibility required (works in Leviton residential panels)
- Whole Home Energy Monitor (LWHEM) required — sold separately (~$100)
- My Leviton app (iOS and Android)
- AFCI/GFCI protection options available
The Leviton 2nd Gen Smart Circuit Breakers take a totally different approach: instead of ripping out your whole panel, you swap individual breakers for smart ones. Your electrician pops them in one at a time — way less invasive than a full panel replacement. SolarTechOnline calls Leviton "the market leader in smart circuit breakers," and it's easy to see why.
At $141–257 per breaker (depending on amperage and AFCI/GFCI protection), a full 20-circuit smart retrofit runs $2,800–5,000 plus installation. That's real savings over a full Span job for homes that don't need a whole new panel. Each breaker gives you remote on/off control, real-time energy monitoring, and load shedding through the My Leviton app. The 2nd Gen also added a dry contact input for generator ATS integration — when your generator kicks on, the breakers automatically shed load to prevent overload. Pro installers love that feature.
The catch (there's always a catch): these only work in Leviton residential load centers. If your home has Square D, Eaton, or Siemens, you'd need to swap the panel enclosure anyway — at which point a Span or Schneider Pulse starts making more sense. But if you already have a Leviton panel, this is the most surgical path to circuit intelligence.
A note on comparing Leviton to the whole-panel options: the per-circuit cost model makes direct SHE score comparison tricky. Leviton looks expensive when you price out a full 20-circuit retrofit, but most people don't smart-ify every circuit — you start with 5–8 high-priority ones (EV charger, HVAC, kitchen) and add more over time. That modular approach is genuinely valuable if you're not ready to drop $7,000+ on a full panel swap.
What We Love
- No full panel replacement — retrofit smart breakers into existing Leviton panel
- Per-circuit remote control — on/off control from anywhere via My Leviton app
- AFCI/GFCI options — safety-enhanced versions available for bedrooms and kitchens
- Generator ATS dry contact — automatic load shedding during generator operation
- Modular approach — electrify circuits one at a time as budget allows
What Could Be Better
- Leviton load center required — doesn't work in Square D, Eaton, or Siemens panels
- Whole Home Energy Monitor (LWHEM) required for full functionality (~$100 add-on)
- Per-breaker cost adds up quickly — 20 circuits at $200 average = $4,000 before labor
- No built-in battery/solar integration at the panel level like Span
- App is functional but less capable than Span's energy management features
Is the Leviton 2nd Gen Smart Breaker system worth buying in 2026?
If you want circuit smarts without writing a $7,000–10,000 check for a full panel replacement — and you have a Leviton load center — the Leviton 2nd Gen Smart Breakers are an easy yes. Start with your EV charger, heat pump, and kitchen circuits. Add more later when the budget allows. If you're planning full solar + battery integration though, the Span panel's dedicated battery management is worth the extra money.
The Verdict
Leviton 2nd Gen Smart Breakers are the best option for adding circuit intelligence without replacing your entire panel — start with 5-8 high-priority circuits and expand over time. If you have a Leviton load center and don't need full solar/battery integration at the panel level, this is the most cost-effective entry point.
"Leviton has established itself as the market leader in smart circuit breakers — the 2nd Gen lineup offers the most comprehensive feature set for retrofit circuit intelligence at the most approachable cost." — SolarTechOnline
Best for Luxury Smart Homes: Savant Power System {#savant}
Price: Packages from ~$1,600 — get quotes on Amazon (full home: $3,000–8,000+ installed)
What's Included:
- Savant Director (manages up to 40 Power Modules, 80 total circuits) — MSRP ~$1,000
- Savant Power Modules (20A dual-circuit, 30A single, 60A single) — ~$120 each
- Savant app integration (requires existing Savant smart home system)
- Compatible with QO, Eaton CH, and 1-inch panel styles
- No panel replacement required
The Savant Power System is for a very specific homeowner: someone who's already deep in the Savant smart home ecosystem. Where Span and Schneider replace your panel entirely, Savant's Power Modules snap into your existing panel — no rewiring, no new enclosure, no touching your current breakers. The Savant Director manages up to 40 modules (80 circuits), and everything ties into Savant's home automation platform for unified lighting, climate, security, and power management.
The modular install is genuinely slick. An electrician pops Power Modules into existing breaker slots in an afternoon — way less disruptive than a full panel replacement. Each module monitors and controls up to two 20A circuits or one high-amperage circuit (up to 60A 240V), covering EV chargers, heat pumps, and major appliances. The Savant integration is where this shines — "Away mode" automatically sheds non-essential circuits, "Movie mode" dims everything except the home theater. It's the kind of automation that makes the smart home crowd swoon.
The honest limitation: without an existing Savant system, the integration benefits disappear and the cost-per-circuit gets hard to justify versus Leviton's smart breakers. This is the right product for a narrow audience — but for that audience, nothing else comes close.
What We Love
- No panel replacement — modules snap into any existing QO, Eaton CH, or 1-inch panel
- Up to 80 circuits controlled — most scalable modular solution in the category
- Deep Savant integration — unified power, lighting, climate, and security in one app
- Scene-based power management — circuit control integrated with smart home automations
- Flexible module types — 20A/30A/60A options cover every circuit type
What Could Be Better
- Best value only for existing Savant smart home customers
- Total system cost can exceed full Span installation in large homes
- Less solar/battery integration focus than Span or Schneider
- Savant ecosystem lock-in — modules only work with Savant Director
- Requires ongoing Savant system subscription/service
Is the Savant Power System worth buying in 2026?
If you already have a Savant smart home, the Savant Power System is a no-brainer — the ecosystem integration is unmatched, and the install barely disrupts your home. For everyone else? The Span Smart Panel has better solar/battery integration, the Schneider Pulse has more circuits and brand reliability, and the Leviton breakers are a more affordable retrofit. Savant's advantage is the ecosystem, not the panel tech itself.
The Verdict
The Savant Power System is the best choice for existing Savant smart home customers who want circuit control integrated with their lighting, climate, and security automations. For everyone else, Span or Leviton deliver more value per dollar.
"Savant Power's modular approach is the most elegant retrofit solution for luxury smart homes — if you're already in the Savant ecosystem, circuit-level energy intelligence installs in an afternoon without touching your panel enclosure." — ProBuilder
SHE Panel Intelligence Score: Which Smart Panel Actually Delivers the Most Intelligence Per Dollar?
We built the SHE Panel Intelligence Score because "which smart panel is best?" isn't a useful question without context. What you actually want to know is: which one gives you the most circuit control, smart features, and integration breadth per dollar spent? We pulled specs from manufacturer docs, EnergySage, 8MSolar, and SolarTechOnline to crunch a single normalized score for each product.
The Formula
SHE Panel Intelligence Score = (Circuit Control Points × Smart Features Score × Integration Breadth) / (Net Cost / 100)
Where:
- Circuit Control Points = number of individually controllable circuits
- Smart Features Score = weighted sum of: energy monitoring per circuit (2 pts), load shedding/backup management (2 pts), solar optimization (2 pts), EV scheduling (1 pt), app remote control (1 pt), voice assistant support (1 pt) — maximum 9 pts
- Integration Breadth = number of distinct ecosystems supported: solar inverter brands, battery systems, EV chargers, smart home platforms (count distinct partnerships/integrations)
- Net Cost = hardware list price in USD (installation excluded — varies too much by region)
SHE Panel Intelligence Score — April 2026 Results
| Smart Panel | Circuit Control Points | Smart Features Score | Integration Breadth | Net Cost | SHE Score | Verdict |
|---|---|---|---|---|---|---|
| Span Smart Panel 200A | 32 | 9/9 | 12 | $3,500 | 99.1 | Best overall |
| Span Panel MAIN 40+MID | 40 | 9/9 | 12 | $4,200 | 102.9 | Best new build |
| Schneider Pulse 200A | 46 | 8/9 | 9 | $3,100 | 107.6 | Best value/circuit |
| Leviton 2nd Gen (20 circuits) | 20 | 7/9 | 4 | $3,800* | 29.5 | Best retrofit |
| Savant Power System (40 circuits) | 40 | 7/9 | 5 | $5,800** | 24.1 | Best luxury/ecosystem |
*Leviton estimated cost: 20 breakers at avg $190 + $100 LWHEM hub = ~$3,900 hardware **Savant estimated: Director ($1,000) + 20 dual-circuit modules at $240 = ~$5,800 hardware for 40 circuits
(SmartHomeExplorer editorial analysis — methodology)
SHE Panel Intelligence Score
Higher = more intelligence per dollar. Formula: (Circuit Control × Smart Features × Integration Breadth) / (Net Cost / 100)
46 circuits · 8/9 features · 9 integrations · $3,100
40 circuits · 9/9 features · 12 integrations · $4,200
32 circuits · 9/9 features · 12 integrations · $3,500
20 circuits · 7/9 features · 4 integrations · $3,800
40 circuits · 7/9 features · 5 integrations · $5,800
SmartHomeExplorer editorial analysis — methodology at /methodology (April 2026)
What this tells you: The Schneider Pulse actually wins on raw SHE score — its 46-circuit capacity and lower price create the best intelligence-per-dollar ratio. The two Span panels land close together, with the MAIN 40+MID edging ahead on circuit count and built-in MID value. Leviton and Savant score lower not because they're bad — they're both excellent for the right buyer — but because per-circuit hardware cost runs high when you equip a full home. Leviton's per-circuit cost model makes direct comparison especially tricky, since most people smart-ify 5–10 circuits, not all 20.
We deliberately left installation costs out of the score because labor varies 3–4x depending on where you live, how old your house is, and where the panel sits. Your installed price could shift these rankings significantly — get at least three quotes.

Who Needs a Smart Electrical Panel in 2026?
Let's be real: a standard US electrical panel costs $1,500–4,000 installed. A smart panel adds $4,000–8,000+ on top. That's a lot of money for a box in your garage. Here's who actually gets their money's worth:
Makes sense:
- Solar + battery homes: Killing the critical load subpanel saves $1,500–3,000 right away. Smart load shedding stretches your battery further during outages. If you're installing a home battery system, the smart panel pays for itself.
- New all-electric builds: Heat pumps, heat pump water heaters, dual EV chargers, induction ranges, and batteries can overwhelm a traditional panel. Smart load management (like the Span MAIN 40+MID) can eliminate the need for 400A service — saving $10,000–17,000.
- Time-of-use rate homes: If your utility charges 2–3x more during 4–9 PM peak hours (CA, NY, TX, and 30+ other states), a smart panel that sheds non-critical loads during peaks and schedules EV charging overnight can save $600–1,800/year.
Probably overkill:
- No solar, no battery, no EV — most of the value disappears
- Renters — your landlord benefits, not you
- Older homes that need a service upgrade first — fix the foundation before you add smart features
Installation: What to Expect
This is not a weekend DIY project. Every product here requires a licensed electrician — you're working directly on the utility connection. Please don't YouTube this one. Here's the typical process:
- Permit pull — your electrician pulls an electrical permit (required almost everywhere). Budget $150–500.
- Utility coordination — the utility needs to de-energize the meter during install. In some regions, schedule 2–4 weeks ahead.
- Panel swap — old panel out, new panel in (or breaker swaps for retrofit options). A full replacement takes 5–8 hours.
- App setup — circuit labeling, backup priority configuration, solar/battery pairing. The fun part.
- Inspection — most jurisdictions require one before the panel goes live.
Total timeline: 2–6 weeks from "let's do this" to working panel, depending on permits and your utility's speed. Total installed cost: $5,500–12,000 depending on product, region, home complexity, and whether your existing wiring needs remediation.
FAQ
Q: Do smart electrical panels qualify for federal tax credits in 2026?
It's complicated. The IRS 25C credit covered qualifying panel upgrades at 30% (up to $600) when paired with a heat pump or similar appliance, but the 2025 deadline passed. For 2026, the status depends on pending legislation — talk to a tax pro before counting on it. The 30% Residential Clean Energy Credit (26 USC 25D) may still apply to battery storage installed alongside a smart panel. And state/utility rebates (check DSIRE.org) can add $300–2,000 in savings regardless of federal credit status.
Q: Can I install a smart electrical panel myself?
Nope. Not legally, anyway — virtually every US jurisdiction requires a licensed electrician and an electrical permit for main panel work. And honestly, working on a live utility feed without proper de-energization is genuinely dangerous. Even the Savant and Leviton retrofit options, which are the closest to DIY-friendly, still need a licensed electrician for the breaker work. Budget $1,500–4,000 for professional installation on top of hardware.
Q: Which smart panel has the best solar integration?
The Span Smart Panel and Span MAIN 40+MID support the most inverter brands — Enphase, SolarEdge, SMA, Fronius, and basically every residential inverter through standard protocols. The Schneider Pulse has a tighter integration with SolarEdge specifically (formal partnership), so if you're already on SolarEdge, that's worth considering. Haven't picked a solar brand yet? Span's ecosystem-agnostic approach gives you the most flexibility.
Q: What's the difference between a smart panel and a whole-home energy monitor?
A whole-home energy monitor (Emporia Vue, Sense, Iotawatt) clips sensors onto your wires to measure energy use — but it can't control anything. A smart panel monitors AND controls, switching individual circuits on and off. Think of it as read-only dashboard vs. full command center. For most homeowners without solar or battery, an energy monitor at $50–200 gives you 80% of the insight at 5% of the cost. Start there.
Q: How much can a smart panel save on electricity bills?
It varies wildly. Homes on time-of-use rates (common in CA, NY, TX, and 30+ states) that use automatic load shifting can save $400–1,800/year depending on their electrical load. Solar homes that stretch battery backup by 40% with smart shedding get more value from the same battery investment. The most reliable number: if you're pairing a smart panel with a battery system, skipping the critical load subpanel saves $1,500–3,000 in install costs alone, which pays back the panel premium in 2–3 years for most homes.
Q: Can a smart panel prevent power outages?
No — it doesn't generate power. What it does is make the power you have (batteries or generator) last longer. By shedding low-priority circuits when backup kicks in, a Span Smart Panel can stretch battery runtime up to 40% vs. traditional subpanel setups. That's the difference between your battery lasting 6 hours and lasting 8.5 hours — pretty meaningful during a multi-day outage.
Q: Are smart panels compatible with generators?
Yes, though integration quality varies. The Span panel handles automatic transfer via its internal MID. Leviton's 2nd Gen breakers have a dry contact input specifically for generator ATS — when the generator kicks on, the breakers automatically shed load to prevent overload. The Schneider Pulse works with Schneider's own generator solutions and third-party transfer switches.
Q: What about the EcoFlow Smart Home Panel 3?
EcoFlow's Smart Home Panel 3 (ASIN: B0G39F2CJN) is an emerging competitor worth watching. It's designed to integrate tightly with EcoFlow's Delta Pro and Delta Pro 3 battery systems, offering circuit-level backup management at a potentially lower price point than Span. That said, it's still early — installer support is limited, and the ecosystem is much narrower than Span's multi-battery compatibility. If you're already invested in EcoFlow batteries, keep an eye on it. For everyone else, the established options above are safer bets in 2026.
The Bottom Line
Smart panels are a big investment for the right home and total overkill for the wrong one. If you have solar and you're adding a battery storage system, the math works: skip the critical load subpanel, stretch battery runtime by 40%, and manage every circuit from your phone. For that use case, the Span Smart Panel 200A is the pick — deepest battery integration, best app, 10-year warranty.
Building new and need 40+ circuits? The Span MAIN 40+MID saves builders up to $10,000 with its built-in MID. Want Square D reliability and 46 circuits? The Schneider Electric Pulse is what your electrician already knows.
Don't want to replace the whole panel? The Leviton 2nd Gen Smart Breakers let you swap in smart breakers one at a time in an existing Leviton load center. And if you're already in the Savant world, the Savant Power System gives you modular circuit control without touching the panel.
Get the Span Smart Panel 200A if you have solar panels and a battery system (or plan to install them) — it eliminates the critical load subpanel, stretches battery runtime by 40%, and gives you the most integrated energy management in any residential panel.
Skip the Span Smart Panel 200A if you don't have solar, a battery, or an EV — without those, most of the value disappears and you're paying $6,500+ for a fancy breaker box.
