Batteries

At the heart of every BESS lies the battery storage unit. These batteries come in various chemistries, including lithium-ion, flow batteries, and lead-acid batteries, among others.

Inverter

The inverter serves as the bridge between the DC output of the batteries and the AC power required for electrical devices. It converts the stored energy into usable electricity.

Energy Management System (EMS)

The EMS is responsible for monitoring and controlling the flow of energy within the BESS. It optimizes charging and discharging cycles to ensure maximum efficiency and performance. 

Working Principle of Battery Energy Storage Systems

Energy Storage Option operates on a simple yet effective principle of storing surplus energy when demand is low and releasing it when demand peaks:

Charging

During periods of low energy demand or excess renewable energy generation, the BESS charges its batteries, storing the surplus energy for later use.

Discharging

When energy demand increases or renewable sources are insufficient, the BESS discharges stored energy, supplying power to the grid or connected devices.
