BES5000L

Flexible DC system architecture

Flexible DC connection for parallel operation or distributed operation for each battery cluster.

Ultra high capacity density

Compared to standard market offerings of 20ft solution with 3~3.5MWh capacity, we are able to deliver 50% more capacity.

Ultra high efficiency cooling

We develop liquid cooling for BESS thermal management. Advanced cooling technology options available to upgrade the system with free cooling and thermal storage. Further with our unique dispatching operation, the system can provide industry leading Round Trip Efficiency (RTE) up to 97%.

灵活直流 超高容量

Advantages

Supports a variety of energy storage architectures

·Centralized Operation.

·Distributed Operation.

Flexible series parallel scheme

The series-parallel connection setup changes the way the battery cluster connects to the power conversion system (PCS) from DC parallel to AC parallel. The PCS and the battery cluster are set up in a "one-to-one" manner, which improves control accuracy by switching from multiple battery clusters to just one.

High efficiency refrigeration mode

LERETECH offers a highly efficient cooling solution with a free cooling module, which can be used in either a centralized cooling plant or connected to individual battery containers. This cooling system is adaptable to various climate conditions. When compared to traditional methods, our solution can enhance RTE by up to 2%.
