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?

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.

Where can a Bess system be used?

BESS systems can be used in a variety of grid positions that differentiate the applications, related to some degree to which side of a billing meter the system sits (in front/on the grid side or behind on the client side):

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.
