Home Battery Backup
Three Rivers Electric installs whole-home battery backup systems across the Twin Cities metro and greater Minnesota. Keep your lights, heat, fridge, and Wi-Fi running when the grid goes down — with clean, code-compliant installs from licensed electricians.
Pair a battery with solar, or run it standalone for outage protection. We size, design, permit, and install it right.
Why add a home battery?
A battery stores power so it is ready the moment you need it — during a storm outage, a utility shutdown, or peak-rate hours. It is a quieter, cleaner, maintenance-free alternative to a portable generator for many homes.
- Automatic backup power during outages — no refueling, no noise
- Keep critical circuits running: heat, sump pump, fridge, medical devices, internet
- Store excess solar energy and use it after the sun goes down
- Reduce reliance on the grid and ride through peak-rate periods
Sizing & system design
The right battery depends on what you want to back up and for how long. One of our designers reviews your panel, your usage, and the circuits that matter most to you, then recommends a system sized to your goals — from essential-circuit backup to whole-home coverage.
Minnesota incentives & financing
Minnesota battery incentives, federal tax credits, and financing options can meaningfully lower your cost. The best path depends on your utility and whether you are pairing the battery with solar — we will walk you through what you qualify for.
What we install
Protect your home from outages with reliable, uninterrupted power from the battery experts.
- Make your home more self-reliant
- System customized to your energy use and needs
- Seamlessly integrates with your home electrical system to store excess power
- Maximum efficiency and reliability with Enphase, HomeGrid or EG4 batteries
- Complete service includes system design, permitting, professional installation, and testing
Certified for the batteries we install
We’re factory-certified on the systems we put in, so you get a valid manufacturer warranty and an install done to spec. Three Rivers Electric installs and is certified for:
- Tesla Powerwall — Tesla Powerwall Certified Installer
- Enphase IQ Battery 10C — Enphase certified
- EG4 — flexible, expandable storage for whole-home or essential backup
- HomeGrid — HomeGrid certified, modular stackable capacity
Because we’re certified across several platforms, we recommend the battery that fits your home, your panel, and your budget — not the one brand we happen to carry.
How a battery connects to your home
A home battery ties into your electrical panel through a transfer or backup gateway so that, when the grid drops, your protected circuits keep running without a flicker. Whether it backs up the whole house or a critical subpanel depends on the battery’s size and your panel’s layout. Older or full panels sometimes need an upgrade or a dedicated backup subpanel first — something we confirm before we quote.
Is your panel battery-ready?
Backup batteries connect through your main panel. Check whether yours has the room in about two minutes.
An update on battery incentives
The 30% federal residential battery credit ended December 31, 2025, so we don’t build quotes around it. Instead we lean on current Minnesota utility programs — including Xcel’s upfront battery storage incentive where it applies — plus financing that keeps the monthly number comfortable. We’ll lay out exactly what’s available for your address.
Frequently asked questions
Which battery brands do you install?
We’re certified on Tesla Powerwall, Enphase (including the IQ Battery 10C), EG4, and HomeGrid. Carrying multiple platforms lets us match the battery to your goals — whole-home backup, essential circuits, solar self-consumption, or peak-rate savings — instead of fitting your home to a single brand.
How big a battery do I need?
It depends on what you want to keep running and for how long. A single battery comfortably covers essentials — heat, fridge, sump pump, internet, and lights — through a typical outage. Backing up the whole home, or riding through a multi-day outage, usually means stacking two or more units. We size it around your actual usage during the walkthrough.
Do I need solar to install a battery?
No. A battery works on its own purely as backup power — it charges from the grid and discharges when the power goes out. Pairing it with solar adds the ability to store your own energy and use it after dark, but standalone outage protection is a very common reason homeowners install one.
Are there rebates or tax credits for home batteries?
The 30% federal residential battery tax credit expired at the end of 2025, so we don’t build quotes around it anymore. We lead instead with available Minnesota utility programs and financing options that keep the monthly number manageable. We’ll tell you exactly what’s current when we quote — no outdated promises.
Will a battery power my whole house during an outage?
It can, with enough capacity and the right setup. A properly sized system paired with a backup gateway can run the whole home; a smaller system backs up a critical subpanel — heat, refrigeration, sump pump, and key outlets — for less. We’ll show you both paths and what each one covers.
How long do home batteries last?
Quality lithium batteries like the ones we install are warrantied for roughly 10 years and are rated for thousands of charge cycles. They run silently with no maintenance, unlike a generator, and many homeowners pair the two for the best of both — instant battery backup plus generator endurance for long outages.
