Federal business tax incentives are available for battery backup systems. Additionally, you can sell electricity to the grid during times of high demand thanks to "net metering" initiatives.

The Reasons Battery Storage Systems Make Sense

A battery backup system should be taken into consideration for a number of reasons. Some are clear, but others might be crucial advantages you haven’t yet thought of.

FAQ's

Solar Battery FAQs

We provide a range of lithium-based batteries with either an LFP battery chemistry or an NMC battery chemistry.
The storage capacity and other variables will determine the price. Our sales representatives will be pleased to offer an estimate that satisfies both your backup requirements and the needs of your house.
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.
Whether or whether they use batteries, the majority of solar energy systems are grid-connected. Through this connection, owners of solar panels can "sell" extra electricity generated by their systems back to the grid in exchange for credits on their subsequent energy bills. A grid-connected solar system without a battery will shut down in the event of a power outage.
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.
Battery storage gives you energy independence, protection from power outages, and better control over your electricity usage. It also helps you maximize savings by using stored energy during peak utility rate hours.
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.
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.
When the grid goes down, your solar battery automatically provides backup power to essential appliances. You’ll still have electricity for lights, refrigeration, and key home systems — keeping you powered and comfortable.
