Technical FAQs 4

What is a battery energy storage system (BESS) & an uninterruptible power supply (UPS)?

Figure 1: A simplified project single line showing both a battery energy storage system (BESS) and an uninterruptible power supply (UPS). The UPS only feeds critical loads, never losing power.

What is a Battery Energy Storage System (BESS)?

A Battery Energy Storage System (BESS) is a cornerstone technology in the pursuit of sustainable and efficient energy solutions. This guide offers an extensive exploration of BESS, beginning with the fundamentals of these systems.

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?

What is an uninterruptible power supply (UPS) system?

Courtesy: Affiliated Engineers Inc. Uninterruptible power supply (UPS) systems have been a familiar presence for years, known for their ability to enhance power quality and offer continuous power for critical loads. These systems typically supply power for a few minutes while the generator starts up.
