SPAN Smart Electrical Panels & Home Energy Management

SPAN Panel circuit-level monitoring, load management and backup priorities for custom homes and estates.

A Smarter Electrical Panel for an All-Electric Home

SPAN replaces conventional distribution with a connected electrical panel that measures and controls energy at the circuit level. The current family includes MAIN 16, MLO 24, MAIN 32, MAIN 40, and MLO 48 configurations, giving the electrical design team options for service equipment, subpanels, renovations, and new construction.

Electrical Design & Installation

PowerUp Load Management Can Reduce Service-⁠Upgrade Pressure

PowerUp is SPAN's embedded energy management system. When a home approaches a configured electrical limit, PowerUp can manage selected high-demand loads to stay below the setpoint. On qualifying projects, that can make it possible to add equipment such as EV charging, heat pumps, or other large loads without automatically upsizing the utility service, subject to load calculations, permitting, and local code approval.

Electrical Service Upgrades

Circuit-Level Visibility, Control & Energy Insight

The SPAN Home App shows real-time household consumption, individual circuit activity, solar production, battery status, and major energy users. Homeowners can turn supported circuits on or off, review energy history, and adjust priorities. SPAN also provides local on-premise access for core monitoring and control when cloud connectivity is disrupted.

Backup Power & Energy Management

Battery Backup That Prioritizes What Matters

When paired with a compatible battery system, SPAN can assign circuit-level backup priorities and automatically reduce nonessential loads during an outage. Current compatibility varies by panel model, with Tesla Powerwall and FranklinWH supported across the current panel family and additional storage integrations available on SPAN Panel MAIN 32.

Solar, Battery & Generator Microgrids

SPAN Drive & Managed EV Charging

SPAN Drive is a Level 2 EV charger designed as an accessory to SPAN Panel. It can dynamically adjust charging based on real-time household demand, charge at up to 48 amps when capacity is available, and schedule charging for off-peak utility windows. Drive is not a standalone charger; it is designed to operate as part of the SPAN energy-management system.

Electrical Design & Installation

Five Panel Configurations for New Construction & Retrofit

SPAN's current MAIN and main-lug-only panel options let the electrical engineer match the product to the home's service architecture and breaker-space requirements. SPAN supports common 1-inch breaker families including listed Eaton, Siemens, and Square D configurations, while NEMA 3R construction supports indoor or outdoor placement where the project and code permit.

Designed as Part of the Whole Electrical & Energy System

A SPAN project should be coordinated with the home's load calculations, utility service, panel schedules, solar, batteries, generators, EV charging, networking, and future electrification plans. Regent5 approaches the panel as part of the complete electrical and technology infrastructure, with design documentation, installation coordination, commissioning, and long-term service considered from the start.

Backup Power & Energy Management

SPAN Panel Family & Energy Management Capabilities

SPAN combines five current panel configurations with software-based load management, circuit-level visibility, flexible battery backup priorities, solar and storage integration, and managed EV charging.

SPAN Panel MAIN 16

A compact main-breaker SPAN configuration for projects that need the platform's monitoring, control, PowerUp, and backup-management capabilities with fewer breaker spaces.

SPAN Panel MLO 24

A 24-space main-lug-only panel intended for subpanel applications where the main overcurrent protection is located upstream.

SPAN Panel MAIN 32

The 32-space main-breaker platform supports SPAN's core energy controls and the broadest current storage-integration set, including supported Tesla, FranklinWH, Enphase, and SolarEdge configurations.

SPAN Panel MAIN 40

A higher-space-count main-breaker option for homes that need additional branch-circuit capacity while retaining SPAN monitoring, PowerUp, app control, and supported battery integration.

SPAN Panel MLO 48

A 48-space main-lug-only configuration for large subpanel applications and projects where a separate upstream main disconnect is part of the electrical design.

SPAN PowerUp™

The embedded energy management system can automatically manage selected high-demand loads so the home stays below configured service or backup power limits.

SPAN Home App

Circuit-level monitoring and control, whole-home power flow, energy history, solar and battery visibility, backup priorities, and supported remote circuit control from one interface.

Battery Backup Priorities

When integrated with a compatible battery, homeowners can prioritize which circuits remain powered, reduce nonessential loads, and update backup priorities as conditions change.

Solar & Storage Integrations

SPAN supports solar monitoring and selected battery platforms. Exact compatibility depends on the panel model, storage equipment, gateway or controller, and required communications hardware.

SPAN Drive®

A SPAN Panel accessory for managed Level 2 EV charging, with dynamic charge-rate control and scheduled charging based on home demand and utility timing.

SPAN Panel Design, Installation and Service

Regent5 designs, installs and supports SPAN smart electrical panels across the San Francisco Bay Area and Northern California. Select engagements extend to Santa Barbara, the Los Angeles area, and Orange County. Projects include custom homes and estates, from circuit planning and backup priorities through commissioning and long-term service.

Frequently Asked Questions about SPAN Smart Panels

Which SPAN Panel is right for my home?

The choice between MAIN 16, MLO 24, MAIN 32, MAIN 40, and MLO 48 depends on whether the panel is service equipment or a subpanel, required breaker spaces, utility service, battery compatibility, backup architecture, solar, EV charging, and future electrification plans. The decision should be made from the electrical one-line and load calculation, not just panel size.

What happens to a SPAN home during a power outage?

With a compatible battery system, SPAN applies circuit-level backup priorities when the home goes off-grid. Critical loads can remain powered while lower-priority loads are reduced or turned off, helping protect the battery from overload and extend useful backup duration. SPAN currently lists Powerwall 3 as compatible across its current panel family when configured with supported Tesla backup equipment. SPAN Panel MAIN 32 also supports selected Enphase IQ Battery systems with the required Remote Meter Kit and supported SolarEdge Home Hub systems.

Can a SPAN Panel help avoid an electrical service upgrade?

Potentially. SPAN PowerUp can manage selected high-demand loads to keep the home below a configured service rating. Whether that can replace a utility service upgrade depends on the load calculation, the home's existing service, local code, permitting authority, and the specific electrification plan.

Who can install a SPAN Panel?

SPAN requires its panels to be installed and commissioned through the SPAN Authorized Installer process. Regent5 can coordinate the C10 electrical design, load calculations, service equipment, battery, solar, EV charging, networking, permitting, and commissioning path so the SPAN scope is resolved before construction begins.

How much does a SPAN Panel installation cost?

Installed cost depends on the SPAN Panel model, existing service equipment, breaker work, utility requirements, permitting, and whether the project also includes batteries, solar, EV charging, or service upgrades. Regent5 scopes the electrical system from the actual plans and site conditions rather than publishing one universal installed price.

Can a large home use more than one SPAN Panel?

Yes, multi-panel configurations are possible and the SPAN Home App can display multiple panels. Model selection matters: SPAN notes that MAIN 32 does not share the same app experience with MAIN 16, MAIN 40, MLO 24, or MLO 48, so large-estate panel architecture should be planned before equipment is ordered.
