Battery and Generator Backup

Solar generates the energy. Backup keeps it available when you need it most.

SRsolarNH installs battery storage and generator backup for new systems and existing arrays across New Hampshire, Maine, Massachusetts, and beyond.

How We Do It

Explore Your Backup Options

Battery Storage

We install carbon lead and lithium battery systems sized to your actual energy usage, for new builds and existing arrays alike.

Generator Backup

A generator paired with your solar array means you are covered through extended outages, cloudy stretches, and anything a New Hampshire winter throws at you.

Compatible with Existing Systems

Already have solar? We can add battery storage or generator backup to your current array, even if we did not do the original install.
Battery and Generator Backup

Power when the sun is not enough.

Solar panels generate clean energy during the day. But what happens at night, during a storm, or after a week of cloudy weather in January? That is where battery storage and generator backup come in.

These are not add-ons. For many homeowners, especially in New Hampshire and Maine, where weather conditions can be demanding, they are what makes a solar system truly reliable year-round.

Battery storage vs. generator backup: what is the difference?

Which one do you need?

Battery storage and generator backup are not mutually exclusive. Many homeowners, particularly those with off-grid systems or properties in rural areas, use both. Batteries cover day-to-day gaps. The generator handles the longer stretches when sun is scarce for days at a time.

If you are on a grid-tied system and want basic backup coverage, battery storage alone may be enough. If you want complete coverage regardless of conditions, combining both gives you the most resilient setup possible.
