Battery backup installation in northwest Montana

When the line goes down in a January storm, your house does not notice. Enphase batteries hand power to the circuits you choose the instant the grid drops, with or without panels on the roof.

Power that stays on when the valley goes dark.

Outages here come with the weather: wind, ice, a tree on the line, and the utility truck hours out. With a battery bank the switchover happens on its own. The well keeps pumping, the freezer stays cold, the furnace fans run, the internet stays up, and if you want the whole house on, the equipment can do that too. Nobody in the house has to do anything, and nobody has to go outside to start something.

Panels are not required. Batteries charge from the grid, so you can have backup this year and add panels whenever you like. With panels on the roof, or added later, the bank refills every day the sun is up while the grid is still down. We size the bank to the list of what has to stay on and put the numbers in front of you. Our own crew designs and installs it, then services what we sell. Labor and every piece of equipment carry a warranty.

Questions about battery backup

Do I need solar panels to get batteries?
No. Batteries charge from the grid and carry your house through an outage on their own, so you can have backup this year and add panels whenever you like. With panels on the roof, the bank refills every day the sun is up while the grid is still down.
What can a battery keep running?
Whatever you put on the list. Most homes start with the well pump, the freezer, the furnace fans, and the internet, and the equipment is whole‑home capable if you want every circuit on. The bank is sized to your list, and the switchover happens on its own.
What warranty comes with the batteries?
Labor and every piece of equipment carry a warranty. The manufacturer’s terms for the exact batteries in your system are written into your quote, so you read them before you sign anything.
Who installs and services it?
Our own crew designs and installs it, the same crew that puts up our arrays, and we service what we sell. More than a hundred systems since 2017, and every review on Google is five stars.
