SPAN Panel Installation
Smart Electrical Panel for Solar, Battery Storage & EV Charging
Your electrical panel used to have one simple job: distribute electricity throughout your property. But energy needs have changed. Today, one property may have solar panels, battery storage, an EV charger, heat pumps, electric appliances, and other high-demand equipment all competing for available electrical capacity. A traditional panel can distribute that power, but it doesn’t give you much visibility into where your energy is going, which circuits are using the most power, or how to prioritize electricity when capacity is limited.
That’s where a SPAN Smart Panel can make a difference. SPAN electric panel provides you with circuit level energy monitoring, load management and backup management customization that will help you manage electrical loads of modern energy needs.
Whether you’re adding solar panels, battery storage, an EV charger, heat pump, or other high-demand equipment, Solar SME is a certified SPAN installer, helps homeowners, businesses, and property owners design a SPAN solution around your existing and future energy needs.
What is a SPAN Smart Panel?
SPAN is a smart electrical panel which replaces or upgrades the function of a conventional breaker panel with energy management and controls. Unlike traditional breaker panels which are only responsible for distribution of power, SPAN offers insights into how individual circuits are consuming power and more control options via the SPAN Home App.
It allows you to monitor energy consumption, power flow from solar and battery storages, manage circuits and set backup priorities. Thus, SPAN is especially useful when dealing with electrification with solar photovoltaic (PV), battery, EV charging, heat pump and other high load appliances.
For property owners considering additional electrical loads, a smart panel can also provide an alternative approach to managing available electrical capacity rather than automatically assuming a traditional service upgrade is required.

Why Install a SPAN Panel?
A conventional electrical panel is basically used for distributing electricity. But the SPAN Panel combines monitoring, automation, and intelligent load management in addition to the electrical system management.
Real-Time Circuit-Level Energy Monitoring
With SPAN Electric panel, you can know the consumption of your electricity in real-time rather than getting it from your monthly bill. With SPAN, circuit-level monitoring and visualization of energy flows can be done using the SPAN Home App.
Intelligent Load Management
As the electrical loads increase, it becomes challenging to manage the electrical capacity. The PowerUp™ energy management system of SPAN can help handle connected loads or electrification projects such as electric vehicle (EV) charging, HVAC upgrade, etc.
Smarter Battery Backup
In case you are using any battery backup as your energy source, SPAN lets you prioritize and allocate the circuit which is powered by the battery during an outage. You can distinguish between essential loads and lower-priority loads to make better use of available battery capacity.
Solar + Energy Storage Integration
SPAN can become the electrical control point connecting your property's loads with solar generation and battery storage, providing greater visibility into how power moves between the grid, PV system, battery and connected circuits.
EV Charging Management
Adding an EV charger can have a higher impact on electrical loads. SPAN can help manage EV charging alongside other loads and available electrical capacity
Remote Energy Control
The SPAN Home App enables remote energy management from a supported smartphone or tablet, giving the user the possibility to keep track of energy consumption without having to stay close to the electrical panel.
SPAN Electrical Panel Models
Currently, SPAN offers different panel configurations that vary in their electrical setup and requirements. The selection of the correct panel is based on your setup, available spaces on the circuit, electricity load, and whether it will operate as a main or sub-panel.
SPAN Panel | Circuit Spaces | Main Breaker | Typical Application |
MAIN 16 | Up to 16 | Yes | Smaller homes, additions, ADUs and select retrofit applications |
MLO 24 | Up to 24 | No | Subpanel applications and projects requiring additional circuit capacity |
MAIN 32 | Up to 32 | Yes | Common whole-property electrical panel replacement applications |
MAIN 40 | Up to 40 | Yes | Larger electrical systems with additional circuit requirements |
MLO 48 | Up to 48 | No | High-circuit-count subpanel applications |
The current SPAN lineup includes MAIN 16, MLO 24, MAIN 32, MAIN 40 and MLO 48. Your installer should select the configuration based on your property’s electrical design rather than simply choosing the panel with the highest circuit count.

SPAN Panel Technical Specifications
The SPAN electric panel is suitable for both indoor and outdoor installations, working with the existing electrical infrastructure but providing advanced energy management abilities. Different technical features of SPAN panels depend on their type. Some common features include:
- 120/240V or 208Y/120V nominal AC configurations
- 60 Hz grid frequency
- NEMA 3R enclosure rating
- Indoor and outdoor installation capability
- Circuit-level AC metering
- Wi-Fi and Ethernet connectivity
- Cellular connectivity on supported configurations
- Compatibility with selected Eaton, Siemens, Square D and other supported breakers
- SPAN PowerUp™ energy-management system
- Backup overload protection
- Support for solar, battery and EV applications
- UL-listed configurations

SPAN Panel with Solar PV Systems:
Make Your Solar Energy System More Intelligent
Solar panels produce electricity; however, it is your electrical panel that decides where this electricity will be utilized. Adding a SPAN Panel into your solar PV system gives you more control and visibility over the electrical usage. You get a chance to monitor your electrical consumption and see how your property is using solar production alongside grid electricity and battery storage.
For customers planning a broader home electrification project, SPAN can provide an intelligent electrical-management platform instead of treating each new electrical load as an isolated upgrade.

Extend Your Battery Backup With SPAN:
Put Your Battery Power Where It Matters Most
Your battery storage has a capacity limit. In case of a grid outage, it might not be necessary to use all circuits at once. SPAN enables users to decide which circuits should be used with battery backup.
With the SPAN Home App, users can set their backup priority and see their available battery capacity. This can help in deciding which loads are important and which can be cut off from using the battery to save energy. Currently, SPAN markets its technology as one that extends battery backup capacity up to 40% during a grid outage.
SPAN Panel with EV Charger Integration:
Charge Your EV Without Losing Control of Your Electrical System
Installing an EV charger can become one of the largest electrical loads for a property. Instead of treating EV charging as a standalone installation, SPAN can help coordinate EV charging with the property’s other electrical loads. With an integrated SPAN Panel and EV charger, homeowners and businesses can better manage charging demand while considering other loads such as HVAC, appliances, solar production and battery storage.
This can be particularly valuable for properties where electrical capacity is limited or where multiple electrification upgrades are planned.
SPAN-Compatible Battery Systems
SPAN can be integrated into energy-storage projects, but its compatibility will depend on the particular SPAN system, as well as the battery/inverter system and architectural design. The SPAN compatible battery backups include:

SPAN Panel for Businesses & Commercial Properties:
Smart Electrical Management Beyond the Home
SPAN isn’t limited to homeowner applications. For small commercial properties, offices, mixed-use properties, multifamily applications and other electrification projects, intelligent electrical monitoring and load management can help provide greater visibility into energy consumption.
Commercial applications may include:
- EV charging infrastructure
- Solar + battery projects
- Electrical capacity management
- HVAC electrification
- Load monitoring
- Backup power planning
- New electrical equipment
- Property renovations and additions
The appropriate SPAN configuration depends on the property’s electrical architecture, service characteristics and applicable codes.
