Use BESS as your UPS

If you’re a facility manager/admin/electrician/engineer looking for a smarter, cost-effective power backup solution, BESS could be the answer to your search. Deploy BESS as a complete UPS solution that delivers uninterrupted power.

What is a BESS?

A Battery Energy Storage System (BESS) is a smart, scalable solution that stores electrical energy, typically in lithium-ion batteries, and delivers it whenever it’s needed. It captures energy from sources like the grid, solar, or wind, and intelligently releases it to power your loads at the right time.

BESS enables a wide range of applications, from reducing electricity bills through time-of-day optimization, to extending solar usage into the night, providing reliable backup (UPS), supporting off-grid operations, and reducing dependence on the grid. It also plays a key role in making energy systems more efficient, resilient, and aligned with the shift toward cleaner power.

How It Works

  • Grid available → BESS starts charging from Grid or Solar, any other sources of energy
  • Grid fails → BESS takes over instantly, in few nanoseconds, seamlessly maintaining power to all connected loads
  • BESS operates primarily as backup power, with energy management features activated over time as the team gets comfortable

Why It Matters

Rising electricity bills, unreliable grid supply, or an aging UPS due for replacement: businesses and customers look for an advanced energy storage.

BESS works around the clock- directly cutting operational costs, eliminates downtime risk, and future-proofs your power infrastructure.

What's in the BESS

BESS is usually made of Lithium ion cells. Compared to Lead-Acid, it is more stable, is more efficient, and longer-lasting. Every BESS deployment is designed for your unique load and hours of backup needed. A hybrid inverter is required for BESS which can be usually provided by your BESS provider.

Good to Know

BESS is sized to your facility's specific load profile, so performance varies by site. Typical open questions before deployment include expected payback period and load criticality mapping- TurnoVolt works through these with you during scoping.
