Backup Power and Energy Independence for South Shore Homes

I'm Dave Simmer, and I've been installing solar and battery systems across the South Shore of Massachusetts since 2011. When the grid goes down during a coastal Nor'easter, standard solar panels shut off for safety. If you want to keep the lights, fridge, and heat running, you need a battery.

But home energy storage is about more than just backup power. It's about true energy independence. A battery lets you store the solar power you generate during the day and use it at night, shifting your usage and reducing your dependence on the grid. And in Massachusetts, your battery can actually pay you back.

Why This Matters in Massachusetts

• The ConnectedSolutions program. This is the game-changer. Utilities like National Grid will pay you for the energy your battery discharges during peak grid events in the summer. It turns your backup power into an active income stream.
• Coastal storms and outages. Out here near the water, losing power is a reality. A battery kicks in instantly and silently when the grid drops—no gas cans, no pulling a cord in the dark.
• It works seamlessly with net metering. Massachusetts has true 1:1 retail net metering. A battery gives you the flexibility to use your power when you need it or let it flow to the grid for credits, giving you total control over your energy.

What I Actually Do

I design and install premium home battery systems, primarily the Enphase IQ Battery and the Tesla Powerwall, fully integrated with your solar array. I don't just bolt a box to your wall; I look at your actual electrical loads and help you decide between whole-home backup or a critical-loads panel (partial backup) that keeps the essentials running without breaking the bank.

I handle the entire process—from load calculations and permitting to installation by my vetted local crews. I also manage the paperwork to get you enrolled in ConnectedSolutions so you can start earning.

Honest Costs and Numbers

Adding a battery isn't cheap. A typical installation ranges from $12,000 to $18,000 before incentives, depending on whether we're backing up the whole house or just key circuits. However, the combination of the MA state tax credit and the ongoing payments from ConnectedSolutions significantly improves the payback period. I'll give you the real numbers for your home.

Is This Right For You?

If you experience frequent outages, have medical equipment that needs reliable power, or want to maximize your energy independence, a battery is a great investment. You can read more about how solar and batteries handle outages.

But I'll be straight with you: if your only goal is the fastest financial payback and you rarely lose power, you might be better off with just solar panels. A battery is a premium addition for resilience. If it doesn't make sense for your home or budget, I'll tell you that too. No pressure.
