Composition of large liquid-cooled solar container energy storage system

What is a 5MWh liquid-cooling energy storage system?

The 5MWh liquid-cooling energy storage system comprises cells, BMS, a 20’GP container, thermal management system, firefighting system, bus unit, power distribution unit, wiring harness, and more. And, the container offers a protective capability and serves as a transportable workspace for equipment operation.

How does an energy storage inverter work?

Energy Storage Inverter: Each battery compartment connects to a 2500kW-PCS, enabling bidirectional energy conversion between the battery system and the grid. The battery compartment employs a 20’GP non-standard container measuring 6058mm×2550mm×2896mm, housing a total of 12 battery clusters, resulting in a total system capacity of 5.016MWh.

What are the functions of the energy storage system?

The energy storage system supports functions such as grid peak shaving, frequency regulation, backup power, valley filling, demand response, emergency power support, and reactive power compensation. The 2.5MW/5.016MWh battery compartment utilizes a battery cluster with a rated voltage of 1331.2V DC and a design of 0.5C charge-discharge rate.

How many volts does a container storage system use?

The world’s largest rolling stock manufacturer says that its new container storage system uses LFP cells with a 3.2 V/314 Ah capacity. The system also features a DC voltage range of 1,081.6 V to 1,497.6 V. From ESS News
