Technical FAQs 4

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 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.

How does a Bess work?

A Battery Energy Storage System (BESS), such as those offered by FusionSolar, works by storing energy in a rechargeable battery and releasing it back into the power grid during peak demand or when renewable energy sources are low. This process involves an inverter and sophisticated control software.

What is the difference between Bess and ups?

They use UPS for surge protection and instant switchovers and BESS to run for 8+ hours during blackouts, powered by solar. The company uses BESS to flatten peak loads and reduce utility bills by 25%, while UPS protects conveyor belts from sudden shutdowns. UPS and BESS both play critical roles, but in different ways.
