Technical FAQs 4

What is energy storage cabinet?

Energy Storage Cabinet is a vital part of modern energy management system, especially when storing and dispatching energy between renewable energy (such as solar energy and wind energy) and power grid.

What type of batteries are used in energy storage cabinets?

Lithium batteries have become the most commonly used battery type in modern energy storage cabinets due to their high energy density, long life, low self-discharge rate and fast charge and discharge speed.

Why do energy storage cabinets use STS?

STS can complete power switching within milliseconds to ensure the continuity and reliability of power supply. In the design of energy storage cabinets, STS is usually used in the following scenarios: Power switching: When the power grid loses power or fails, quickly switch to the energy storage system to provide power.

How to design an energy storage cabinet?

The following are several key design points: Modular design: The design of the energy storage cabinet should adopt a modular structure to facilitate expansion, maintenance and replacement. Battery modules, inverters, protection devices, etc. can be designed and replaced independently.
