Technical FAQs 4

What is an uninterruptible power supply (UPS) system?

Power distortions such as power interruptions, voltage sags and swells, voltage spikes, and voltage harmonics can cause severe impacts on sensitive loads in the electric systems. Uninterruptible power supply (UPS) systems are used to provide uninterrupted, reliable, and high-quality power for these sensitive loads.

Are battery-backed uninterruptable power supplies reliable?

Reliability of power sources is an increasing challenge in many sectors and battery-backed uninterruptable power supplies (UPS) are one option to protect and keep electronic equipment operating in the event of grid power failure.

Should you buy a ups or a Bess system?

UPS systems are cheaper upfront. But their batteries wear out faster and aren’t designed for daily use. BESS systems are more expensive initially, but they offer long-term savings through energy arbitrage, grid incentives, and durability (especially with lithium iron phosphate batteries). Which One Should You Choose?

How to choose a good AC UPS system?

The quality of output voltage is the most important factor. The output voltage of an AC UPS system should be sinusoidal with low THD in different loading conditions even with nonlinear loads. The control system should have small transient responses to provide appropriate line conditioning in different loading profiles.
