FAQ's
Common Rhode Island Energy Storage Questions
In Rhode Island, a battery system acts as a smart bridge between your solar panels and the utility grid. During the day, your panels charge the battery; at night or during an outage, your home draws from this stored energy instead of the grid. This setup allows for "islanding," meaning your battery automatically disconnects your home from the utility during a blackout to keep critical appliances, like refrigeration and medical equipment, running safely.
We provide a range of lithium-based batteries with either an LiFePO4 (Lithium Iron Phosphate) battery chemistry or an NMC (Nickel Manganese Cobalt) battery chemistry.
Yes. Through Rhode Island Energy’s 0% financing program, eligible Rhode Island residential customers can access zero-interest financing for residential battery storage systems. Low-income customers on the A-60 rate can apply for a 0% loan to cover equipment and installation costs when paired with enrollment in the ConnectedSolutions battery program. This lets you spread the cost of your battery system over time without paying interest, making storage more affordable while you earn incentives and build resilience.
The Renewable Energy Fund (REF) offers a specific grant called the Energy Storage Adder to lower your upfront costs. For 2026, homeowners who install a battery at the same time as their solar system can receive a flat $2,000 grant. Because this is a grant and not a tax credit, your installer handles the application and applies the $2,000 as a direct discount on your system price.
ConnectedSolutions is a utility-run demand response program that pays battery owners for allowing limited use of stored energy during peak demand events. Both homeowner-owned and third-party-owned battery systems can participate.
For homeowner-owned batteries, incentive payments are typically paid directly to the homeowner.
For batteries installed under a lease or managed ownership structure, ConnectedSolutions revenue is incorporated into lower monthly costs or shared
The solution to this is complicated and contingent upon several variables. These variables include the quantity and charge of batteries at the time of the outage, the amount of energy the property is using during an outage, and more. The size of a battery or bank of batteries should be sufficient to power your house until the grid is restored. You might install a smart service panel solution, like a SPAN panel, to have better control over how much electricity you use during an outage.
Yes. You can install a home battery as a standalone system without solar panels. In this configuration, your battery connects directly to your home’s electrical panel and charges using electricity from the utility grid.
Most modern solar batteries last between 10 to 15 years, depending on usage and environmental conditions. OneGrid installs premium-grade batteries with long warranties and reliable performance for years to come.
Indeed. Because battery storage systems are modular, you can always add more capacity. It's advisable to build a new solar panel array with batteries in mind if you anticipate adding them in the future.
Yes! If you already have a solar system, OneGrid can retrofit a compatible battery storage solution. Our team evaluates your setup and recommends the best integration for optimal efficiency and savings.
It depends on your energy habits and system size. OneGrid’s specialists perform an energy assessment to help you choose the right battery size for your household needs and backup goals.
Absolutely. While lithium-ion batteries can be sensitive to extreme cold, leading manufacturers now include integrated heating blankets and liquid thermal control systems to ensure optimal performance even in low temperatures. Solar panels actually become more efficient in cold weather, allowing them to continue trickling power into your battery even on sunny but freezing January days.
