How many categories of energy storage cabinets are there?

1- Discrete energy storage cabinet: composed of a battery pack, inverter, charge, and discharge controller, and communication controller.

Each component is placed independently in the cabinet, connected through cables, and combined into a system.

The advantage of this structure is that each part of the equipment in the energy storage cabinet is independent, the failure rate is low, and it is easy to maintain and expand. But the disadvantage is that it occupies a large area and costs high.

2- Combined energy storage cabinet: The battery pack, inverter, charge, and discharge controller, and communication controller are installed in independent cabinets.

Cabinets can be combined arbitrarily to form energy storage systems with different capacities, voltages, etc.

This structure has free combinations, high flexibility, and can be customized according to user needs.

But the disadvantage is that cabinet connections are complicated and installation is difficult.

3-Base-type energy storage cabinet: A structure in which the battery pack and power devices are installed on the base.

This structure occupies a small area, is easy to install, and is suitable for outdoor environments. However, the disadvantage is that the energy storage capacity is relatively small and not suitable for large-scale applications.

4-Integrated energy storage container: The battery pack, inverter, charge, and discharge controller, and communication controller are integrated into one cabinet.

This structure has compactness, portability, and easy installation, making it suitable for mobile energy systems or small grid systems.

However, the disadvantage is that the system has poor scalability and faults are difficult to troubleshoot.
