As homeowners in Connecticut explore ways to reduce their reliance on the power grid and manage rising energy costs, understanding battery storage basics is essential. Battery energy storage systems (BESS) allow homeowners to store excess energy generated by their solar panels or during periods of low-cost electricity and use it when energy prices are high or during power outages.
At Shedd Energy, we help homeowners integrate battery storage technology into their renewable energy systems. Our goal is to offer energy dependency relief and ensure continuous energy supply even when the electric grid is down. If you’re considering a battery energy storage system, this guide will walk you through the basics and the benefits of adopting an energy storage solution in your home.
What is a Battery Energy Storage System?
A battery energy storage system (BESS) is designed to store electrical energy for later use. These systems are typically paired with solar energy generation, allowing homeowners to use stored energy when the sun isn’t shining or when electricity demand is high. The main components include:
- Battery modules: Store electrical energy in lithium-ion batteries or lead-acid batteries, with the former being far more popular.
- Power conversion system: Converts stored DC electricity into AC power for household use.
- Battery management system: Ensures the safe and efficient operation of the battery storage system.
How a Battery Storage System Works
- Energy Capture: The energy used to charge the battery system comes from the home’s solar panels or the power grid. Excess energy not being used by the home charges battery energy storage system.
- Energy Storage: The battery system retains stored energy for later use. If the home doesn’t need to use the energy, it simply remains stored in the batteries.
- Energy Release: When energy demand is high, or during a power outage, the system supplies power to the home. This energy supplements the home with power that the solar panels can’t supply or simply with cheaper electricity purchased during low-cost hours
- Limited Grid Interaction: While some advanced systems can interact with the grid, meaning they may be able to supply energy back to the grid, most residential batteries primarily store excess solar energy for home use during high-cost hours.
The Benefits of Battery Energy Storage
Lower Energy Costs
A battery storage system allows homeowners to reduce their reliance on the electric grid and benefit from lower electricity costs. Some systems can be programmed to charge during low-cost energy periods and discharge during high-rate hours, reducing overall electricity costs compared to a similar home without a BESS system.
Backup Power During Outages
With Connecticut experiencing occasional unpredictable weather, a battery storage system can supply backup power during storms or power outages. However, most residential batteries do not provide whole-home backup but can power essential loads such as refrigerators, lighting, and medical equipment.
Increased Energy Independence
A battery energy storage system allows homeowners to rely less on fossil fuels and reduce their carbon emissions. By combining battery storage with solar energy supply, households can create a more sustainable energy model. This may also lead to local and federal incentives, allowing homeowners to save money through tax credits and rebates.
Battery Storage Options for Connecticut Homes
Lithium-Ion Batteries
Most modern battery energy storage systems use lithium-ion batteries because of their efficiency, longevity, and high energy density.
Lead-Acid Batteries
While less common today, lead-acid batteries are still used in some battery storage applications due to their lower upfront cost. They’re more common in off-grid scenarios than home installations.
Is Battery Storage Right for Your Home?
Homeowners considering a battery storage system have some points to think about. This includes:
- Energy consumption: If you experience high energy demand, a battery system can help regulate your costs—especially if the supplier increases the cost during high-demand hours.
- Solar energy generation: If you already have solar panels, a battery energy storage system can maximize their efficiency. When they overproduce renewable energy, the power can be stored for later.
- Electricity costs: If your utility rates fluctuate, a battery storage system can help you optimize your electricity supply and create more reliable utility bills over time.
- Backup power needs: Most residential battery systems provide partial backup, meaning they power essential appliances rather than the entire home. They’re not quite as powerful as a backup generator, which may have the ability to power the whole home if it’s sized to do so.

Battery Energy Storage FAQs
How does a battery storage system work with solar panels?
A battery storage system captures excess energy from solar panels and stores it for later use, allowing homeowners to maintain a continuous energy supply even when the sun isn’t shining or when energy rates are at their highest.
What are the benefits of a battery energy storage system (BESS)?
A battery energy storage system provides backup power, reduces electricity costs, and supports the power grid by reducing strain during peak hours.
What is the difference between lithium-ion and lead-acid batteries in energy storage systems?
Lithium-ion batteries are more efficient, have a longer lifespan, and provide higher power capacity, while lead-acid batteries are more affordable but have shorter lifespans and lower energy density. We install lithium-ion batteries, but some off-grid storage systems may still use lead acid.
Can a battery storage system help during power outages?
Yes, a battery storage system ensures backup power when the electric grid goes down, helping homeowners maintain a continuous energy supply. It might not be able to power the whole home like a backup generator, but it can produce enough power for essential circuits.
