Intelligent Temperature Control

The thermal management system can be selected according to the operation scenario, including three cooling methods: natural air cooling , forced air cooling and air conditioning cooling

Fresh Air Intake+Cold Air Circulation

Cold air is circulated from the bottom of the battery pack to effectively dissipate heat, control equipment temperature, extend service life, and reduce the failure rate caused by high temperatures

Freedom to Expand Capacity as Needed

Modular design allows for easy assembly (30 minutes) and flexible expansion. Versatile solution for C&I energy needs
