Every other solution on this page — NeoCharge, ConnectDER, the DCC-12 EVEMS — solves one problem: adding EV charging without a panel upgrade. They do it well. They’re the right answer for homeowners who need exactly that and nothing more.
SPAN solves a different problem: what happens when you need EV charging and solar and battery storage and dynamic load management and whole-home energy visibility — and you want all of it working together, automatically, without managing four separate systems.
SPAN is a full 200A panel replacement. It doesn’t add to your existing panel. It replaces it. And in doing so, it turns a dumb piece of mid-century electrical infrastructure into the most sophisticated energy management system available for residential use.
KiloWire is a SPAN-certified installer. This is what you need to know before deciding if SPAN is right for your home.
The Core Difference: SPAN Manages Every Circuit, Not Just the EV
The DCC-12 EVEMS manages one circuit — the EV charger. When the house load is too high, it cuts the EV charger. Everything else runs as usual.
SPAN manages every circuit in your home simultaneously. It knows what every breaker is drawing, in real time, down to the individual outlet level. And it can take action on any of them — automatically, based on rules you set — without your involvement.
This is the difference between a traffic light at one intersection and air traffic control for your entire home.
Practical example: Your battery is at 40% charge. Peak rate hours start in 30 minutes. SPAN knows your EV is plugged in and your water heater is running. Without any input from you, SPAN finishes a quick water heater cycle, pauses the EV charger, switches from charging your battery from solar to holding charge for discharge, and at 4:00pm starts powering your home from the battery instead of the grid. At 9:01pm when off-peak rates return, SPAN resumes EV charging and queues the water heater for a cheap overnight cycle.
You didn’t do anything. SPAN did.
The Hardware: What SPAN Actually Is
SPAN is a physical electrical panel — a UL-listed enclosure with a built-in 200A main breaker, up to 32 individual circuits, and the following integrated into every circuit position:
Energy monitoring: Each circuit has a current sensor reporting wattage in real time to the SPAN app. You see exactly what every breaker in your house is drawing, updated every second.
Remote relay control: Each circuit can be turned on or off remotely via the SPAN app, from anywhere. You’re on vacation and you left the garage heater running? Off. You want to cut power to the kids’ rooms at 10pm? Scheduled. Breaker keeps tripping? Identify the overloaded circuit in seconds.
Dynamic load management: SPAN’s intelligence layer continuously monitors total panel draw and manages large loads — EV charger, water heater, HVAC — to stay within safe limits. Unlike the DCC-12 (which can only cut the EV circuit), SPAN can prioritize and shed multiple loads intelligently.
Battery and solar integration: SPAN coordinates directly with Powerwall, Enphase, Franklin WH, and other battery systems. It manages the charge/discharge schedule, backup load priorities, and solar self-consumption automatically.
Built-in touchscreen: A full-color display on the panel face shows real-time home energy data. Your electrical panel now has a screen, because it needs one.
The UL 3141 Certification: Why It Matters in 2026
SPAN was the first residential smart panel to receive UL 3141 certification — the highest Power Control System safety standard in North America. This isn’t a marketing credential. Under the 2026 National Electrical Code, UL 3141 is a requirement for smart panels used in dynamic load management applications.
In plain language: if you want a smart panel that legally manages your home’s load under NEC 2026 rules, it needs UL 3141 certification. SPAN has it. Most competing products don’t.
This matters for permitting. An inspector in an NEC 2026-adopted jurisdiction reviewing a smart panel installation will look for UL 3141. SPAN passes that check. A competing product without the certification may not.
California adopted NEC 2026 with amendments effective 2025. LA County follows state adoption. KiloWire’s SPAN installations comply with both the NEC 2026 requirements and California Title 24 electrical standards.
When SPAN Makes More Sense Than Simpler Solutions
SPAN is a full panel replacement. It costs more than a DCC-12, more than a ConnectDER, and more than NeoCharge. It’s not always the right answer.
SPAN is the right answer when:
You’re adding EV charging and battery storage in the same project. The coordination between battery, solar, and EV load is complex enough that a single integrated system is significantly more effective than separate components.
You’re doing a full home electrification upgrade — heat pump, heat pump water heater, induction range, EV charging — and need whole-panel load management to fit it all on your existing service.
You have (or plan to have) two EVs and need intelligent prioritization between chargers.
You care about energy visibility and want to know where your power goes, which circuits are drawing what, and how your usage maps to your rate plan.
You’re planning for PSPS (Public Safety Power Shutoff) resilience and need granular control over which circuits receive backup battery power.
SPAN is more than you need when:
You just need EV charging and your panel has one slot open. A DCC-12 EVEMS at a fraction of the cost does that job cleanly.
You have no plans for battery storage, solar, or additional electrification. The advanced coordination features aren’t relevant without those loads.
The Certification Requirement: Why This Is Not Optional
SPAN maintains a network of authorized, certified installers. KiloWire is one of them. The certification process is not ceremonial — it covers:
- SPAN’s specific installation methodology (which differs from a standard panel swap in important ways)
- Integration protocols for Tesla Powerwall, Enphase, Franklin WH, and other battery systems
- SPAN’s load management configuration and commissioning
- App setup, monitoring configuration, and customer handoff
Why this matters practically:
Warranty: SPAN’s 10-year product warranty requires installation by a certified contractor. An uncertified installation voids the warranty on a $3,500–$5,000 piece of hardware.
System performance: A SPAN panel that isn’t correctly commissioned — with load priorities set, battery integration configured, and TOU schedule programmed — is just an expensive traditional panel. The value is in the configuration, not the hardware.
Permit documentation: SPAN installations require an electrical permit. The permit application must correctly document the SPAN as a UL 3141 certified Power Control System. Certified installers know how to do this. Non-certified contractors often don’t, which creates permit delays or rejections.

The Honest Summary
SPAN is the most capable residential electrical panel available. It eliminates the need for service upgrades in many whole-home electrification scenarios, manages every circuit intelligently, integrates battery and solar into a single coordinated system, and is built on the only UL 3141-certified platform on the market.
It is also a significant investment that requires a SPAN-certified C-10 licensed contractor to install correctly, commission fully, and warrant properly.
KiloWire is that contractor in the Greater Los Angeles area. We handle the permit, the installation, the battery integration, the commissioning, and the inspection — and we stay available after the job is complete.
