Battery Backup for Your Home

Keep the lights on — even when the grid doesn’t.

Power outages in Minnesota aren’t a “maybe.” They’re a seasonal hobby. A home battery backup system keeps critical circuits (or your whole home) running when the utility goes down—quietly, instantly, and without hauling gas cans around.

What is a home battery backup system?

A battery backup is a rechargeable energy storage system installed in your home. It can power your home during outages by automatically switching from the grid to your battery—often in seconds.

Depending on your goals, it can be designed to:

• Back up essential circuits (fridge, outlets, sump pump, Wi-Fi, furnace fan, etc.)
• Back up most of the home
• Back up the whole home (with the right design + loads)

Why homeowners install battery backup

Outage protection

When the grid goes down, your battery can keep your essentials powered—no extension cords, no manual setup.

Quiet + clean

No engine noise. No fumes. No fuel storage. No “why is the garage smelling like a lawnmower?”

Smarter energy use

Batteries can help you use more of your own solar power and reduce reliance on the grid.

Peace of mind for critical needs

Great for homes with:

• Medical equipment (CPAP, oxygen concentrators, refrigerated meds)
• Sump pumps / well pumps
• Home offices that can’t afford downtime

Battery backup options we install

We’ll recommend the right setup based on your home, electrical panel, and what you want to power.

Common system types:

• Essential-load backup (most popular, best value)
• Whole-home backup (bigger system + load management)
• Solar + battery (battery charges from solar and the grid)

Already have solar? No problem—battery can often be added to existing systems.

What determines battery backup cost?

Battery systems vary based on:

• How much you want to power (essential vs whole home)
• How long you want it to run during an outage
• Your home’s electrical setup (panel capacity, service size, subpanel needs)
• Whether you’re adding solar or integrating with existing solar

We’ll walk you through options and pricing clearly—no mystery math.

Battery Backup FAQs

Will it power my whole house?
It can—if the system is sized for it. Many homeowners choose essential-load backup for a smarter price/performance balance.

Does it work when the grid is down?
Yes—when designed correctly. We’ll confirm the system’s outage behavior and automatic transfer design during quoting.

Can I add a battery later if I get solar now?
Often, yes. We’ll design with expandability in mind when possible.

Is a generator better than a battery?
Depends. Batteries are quieter and instant; generators can run longer with fuel. Some homeowners do both for the ultimate “I don’t care what the weather does” setup.
