BATTERY ENERGY STORAGE
Commercial battery backup power.
Instant, silent ride-through for the loads that can't blink when the grid does.
WHEN THE GRID DROPS
How battery backup keeps a building running
Commercial battery backup does one job with no drama: when the grid fails, the building's critical loads keep running, instantly. No crank, no fuel, no ten-second gap while a generator wakes up. The transfer is fast enough that computers do not reboot.
A complete system is more than batteries: an inverter to convert the power, a battery management system watching every cell, an automatic transfer switch that makes the cutover, and an enclosure keeping it all at the right temperature. Sized to the critical loads - not the whole building - most commercial systems carry several hours comfortably.
WHAT STAYS ON
How to size battery backup for a building
The first design decision is the honest list: what must stay on. Refrigeration, servers, life safety, access control, a few circuits of lighting. Backing up everything costs a multiple of backing up what matters.
Typical commercial systems carry critical loads for up to about four hours - enough to ride out most outages and shut down gracefully in the rare long one.
DOUBLE DUTY
Battery backup benefits beyond outages
Here is what separates batteries from every other backup option: the same system earns on ordinary days. It shaves demand peaks, shifts usage to cheap hours, and can sell flexibility through utility programs.
A generator waits for emergencies. A battery works the whole year and still answers the emergency. That daily work is what pays for the insurance.

QUESTIONS
Straight answers.
How long can a battery back up a building?
Sized to critical loads, several hours is standard - about four is a common design point. Longer runtimes mean more capacity or pairing with a generator.
Is the switchover really seamless?
Yes. The transfer happens fast enough that computers and sensitive equipment ride through without rebooting - a real difference from generator startup.
Battery or generator for backup?
Batteries win short outages and earn daily; generators win multi-day outages on fuel. Many facilities pair both. See our comparison page for the full breakdown.
What loads should be backed up?
The list that hurts when it stops: refrigeration, IT, life safety, access control. Backing up everything costs a multiple of backing up what matters.
