Power your home with a battery storage system
You never know when extreme weather will unexpectedly cut power to your home. Battery energy storage systems (BESS) offer peace of mind by storing power for later use, ensuring it’s available when you need it most, like during a power outage or when electricity prices are higher. During a power outage, your battery can automatically back up your home.
Battery storage systems store power from the electrical grid or your solar panels. They can charge when electricity rates are low and discharge when rates are high, helping you to manage energy costs.
A home battery storage system can help you save on energy costs1 and increase your energy independence by reducing your exposure to fluctuating power prices and grid failures.
We offer whole home and partial home battery storage systems
Partial home battery storage
A partial home backup power system keeps the critical items in your home running whenever there is a power outage. These systems feature seamless, automatic backup power that works whenever you need it.
Power for your essentials
When the power goes out, your partial home battery storage can still run items like:
- Refrigerator & freezer
- Medical devices
- LED lighting
- Microwave
- Toaster oven
- Air fryer
- Ceiling fan
- Wi-Fi
- Television
- Kettle
- Computers
- Garage door opener
- Furnace (gas only)
- Window air conditioner (up to 120V)
- Water heater (gas only)
- Sump pumps/well pumps
Energy when you need it
Partial home battery storage provides back up power when a power outage occurs. In the event of an outage, the battery automatically switches to backup power without any energy input or power interruption.
Seamless backup
A partial home battery storage system detected outages to provide seamless power backup for your essentials.
Cost savings on energy usage
The battery system can charge from the grid when it is less expensive and stores energy to use during peak rate times.
Monitoring
The app enables you check the status of your backup power systems whenever you want, wherever you are.
Partial home battery storage brands we offer:
- BESI Electrafy
Whole home battery storage
A whole home battery storage system is designed to maximize your home’s energy independence. That means seamless backup, , and potential savings on your electricity bill.
The battery storage solutions we offer can be customized to your energy needs, with the ability to charge from solar and the grid so energy is always available on demand.
Power your entire home
A whole home battery storage system can power your entire home, including your heater or air conditioner and other large appliances.
Energy anytime you want it
Whole home battery storage makes stored energy available whenever you need it, including during the day, at night, and when an outage occurs.
Seamless backup
The battery storage system detects outages to provide seamless power backup for your home.
Cost savings on energy usage
If your utility company offers time-of-use rates or ultra-low overnight rates, the battery storage system can charge when energy costs are low and then power your home when energy costs are high to reduce the cost of your energy usage.
Monitoring
Our battery storage solutions use smart apps to monitor energy use and production in real time and to enable you to manage your energy preferences.

Frequently asked battery storage questions
- A battery storage system can store power from renewable energy sources, like solar panels, or from the electrical grid for later use. This energy can be released when it is needed, including during a power outage or when power from the grid is more expensive.
Tesla Powerwall 3 and Canadian Solar EP Cube’s battery storage can charge from solar panels and the grid. BESI Electrafy’s battery storage charges from the electrical grid. - A control panel is included with the battery, which is like the brains of the system. When there is no power going through your meter, the control panel immediately tells the battery to release power into the home. This process is so seamless that you probably won’t even notice that the switch has been made.
- You can use your stored electricity at any time and for any reason. The battery will provide seamless backup power by detecting grid outages and automatically becoming the home’s main power source.
- Whole-home battery backup systems (like Tesla Powerwall 3 and Canadian Solar EP Cube) can power your entire home in the event of an outage, whereas partial-home setups (BESI Electrafy) support the essentials.
- Each battery varies in capacity, holding anywhere from 3.6 kWh to 13.6 kWh of electricity. They can provide power from a few hours up to several days. How the battery system’s storage capacity translates into available power for your home depends on your home’s energy usage, what you choose to power, and other factors.
The exact number of batteries needed will depend on the home’s energy usage, the desired backup power duration, and the individual batteries’ capacity. During your consultation, a battery storage expert can advise you on the number of batteries required to meet your energy needs. - The amount of money you can save depends on your energy use, utility rate, rate structure, and several other factors. If your electricity rates vary throughout the day, a battery energy storage system can charge when your utility’s electricity costs are low and discharge when electricity costs are high, generating automatic savings.
A battery storage system stores electrical energy, and a generator generates electricity. We recommend battery storage if you are experiencing shorter energy outages, while a generator is best for extended outages.

A certified electrician can make the recommendation after pre-inspection.
- Site assessment: A battery installation professional comes and surveys your home for the best place to install the battery.
- Energy audit: If your battery is being installed with solar, the installer will want to get an idea of your energy consumption to correctly size your systems.
- Permitting: A standalone battery may need permits to be installed and permission from the utility to feed energy back to the grid, just like a solar system.
- Inverter installation: Your battery may need an additional inverter to convert the DC electricity it stores into the AC electricity your house uses.
- Mounting: The battery will be installed, usually on a wall or the floor.
- Connection: Your battery will be connected to your house’s electrical system and tested to make sure it’s working.
- Monitoring: Monitor your battery’s charge and performance through the manufacturer’s app.
