Home Battery Backup System Installation

A home battery energy storage system stores electricity — usually from your solar panels — so you can use it later when the sun isn’t shining or during a power outage. Solar batteries work by providing backup power during outages, ensuring your essential appliances and lighting remain operational even without grid access. It helps you maximize your solar investment, lower your energy bills, and keep your home running when the grid goes down.

Adding a battery allows you to store excess solar energy during the day—including capturing excess energy that would otherwise be sent to the grid—and use it at night or during peak‑rate hours. This reduces your dependence on the grid, protects you from rising utility costs, and ensures you have reliable power during outages.

Yes. We can install battery storage as a stand‑alone backup system or integrate it with existing solar panels, generators, or EV chargers. Our team designs each system to match your specific home and energy needs.

Insight Energy installs FranklinWH, Enphase, and SolarEdge energy storage systems. Each model offers different capacities, smart‑home management features, and scalable options. We’ll help you compare them and choose the best fit for your lifestyle and energy goals.

They typically maintain over 70% capacity after 15 years, backed by a 15‑year warranty, ensuring consistent performance and long‑term value.

Absolutely. Battery systems are modular and scalable, allowing you to add more batteries as your energy needs grow. You can start with one unit and expand up to 15 batteries per gateway for whole‑home backup power.

During an outage, your battery automatically provides power to keep essential devices running — such as lights, refrigerators, sump pumps, and medical equipment. Larger battery energy storage systems can also support high-energy loads like air conditioning, depending on battery capacity. When paired with solar panels, the system can continue recharging during the day, extending your backup supply indefinitely.

Yes. Solar batteries operate reliably from ‑4°F to 130°F, making them well‑suited for New England’s temperature swings. They’re built to deliver steady performance through snow, rain, and heat.

Yes. Insight Energy can integrate gas generators or EV power sources into your home energy system for hybrid backup capability. The same lithium-ion battery technology used in electric cars is also used in home energy storage systems, providing reliable backup power and energy efficiency. This ensures consistent power even during extended outages or high consumption periods.

By using stored solar energy during peak‑rate hours, you reduce what you buy from the grid when electricity is most expensive. This lowers your monthly bills and protects your solar investment as net metering and rate structures change over time.

You don’t have to figure it out alone. Insight Energy’s experts will assess your home’s energy usage, backup needs, and system size to design the best solution for you. We’ll walk you through your options, explain potential tax incentives, and handle everything from permitting to installation.
