1. What is BESS?

BESS, short for Battery Energy Storage System, is an advanced energy storage technology solution widely adopted in the renewable energy sector. Within the industry, it is commonly referred to as “BESS” or “BESS batteries.” Its core function is to store electricity generated from renewable sources such as solar and wind energy, and release it during peak demand periods, power outages, or times of high electricity prices.

The most typical application scenario for BESS is integration with solar systems: charging during sunny daytime hours and releasing electricity at night or during periods of power shortages, helping users achieve energy self-sufficiency, cost optimization, and power reliability. Especially in addressing the intermittent power generation issues of renewable energy, BESS plays a particularly critical role.
