What is Battery Storage?
Battery storage provides back-up power for your home in case of a electrical outage. The battery is charged up and drawn down using your home’s electrical system.
Battery Storage
Battery Storage is ideal for:
Homes with Solar Electricity / Generator Replacements
The Technology
How It Works
- The battery is charged by solar electricity if you have solar panels or by utility-supplied electricity if you don’t.
- If the battery is paired with solar electricity, energy generated during the daytime and stored by the battery can be used to power your house at night.
- Homeowners can size their battery storage system to power critical loads, such as a refrigerator, in an electricity outage.
Important: If you have a solar electric system and want to power portions of your home and/or re-charge your home battery with solar energy during a power outage, talk to your installer about islanding capability.
Why Should I Consider Battery Storage?
Battery storage offers a convenient and easy way to provide electricity to your home in a power outage.
Resiliency
Take the stress out of electrical outages by having a backup source of power
Ongoing Revenue
Battery storage systems can generate additional credits or payments from your utility
See MassSave’s Connected Solutions program and HEAT Loan
No Hassle
Power is stored in an inconspicuous box attached to the wall and doesn’t require separate fuel, need mechanical upkeep, or produce on-site emissions
Complements Solar
Charge your battery with solar electricity then use the battery during times when the solar panels aren’t producing energy
Things to Consider
Is Battery Storage right for me?
Every home is different. We strongly encourage you to speak with an installer to see if Battery Storage meets your needs.
How can battery storage be used in homes?
Battery storage is used to power homes during a utility outage or at night if excess electricity has been generated by your solar panels during the day.
Do you already have a Solar Electric System?
Battery storage complements solar electricity. Electricity created from the solar panels can be stored and then used at night or during power outages. During a multi-day power outage, solar panels can recharge your battery if the system is configured with islanding capacity. Talk to your installer about how to configure your solar panels and battery storage to best fit your needs.
Can you buy battery storage if you don’t have solar electricity?
Yes, for homes without solar electricity, the battery storage will be charged by grid electricity.
Do you have frequent power outages?
Battery storage is a lower-maintenance, cleaner way to provide electricity to your home during a power outage compared to using a diesel- or propane-fueled generator.
How can you receive revenue from battery storage?
Battery storage systems can generate additional credits from your utility when paired with a solar electricity, as well as provide an opportunity for payments from your utility when the battery is dispatched at times of peak energy use by the grid.
How long can battery storage power your home during an outage?
It depends your electricity consumption during the outage and the storage capacity of your battery/ies. Many residential batteries can last one to two days if you are only using them to power essential loads.
