Case

U.S. Commercial BESS Cooling Solution for Solar Energy Storage

Customer Background

A U.S.-based renewable energy company focusing on commercial and industrial battery energy storage systems (BESS) for solar power applications. The project was applied to a 261 kWh C&I BESS, where precise and reliable thermal management is essential for system safety and performance.

Project Challenges

The customer required a cooling solution that could:

Use R-513A environmentally friendly refrigerant
Comply with CE certification standards
Operate reliably in extreme heat and cold climates
Support remote monitoring and automatic temperature control
Deliver a 6 kW cooling capacity to ensure stable internal cabinet temperature

Our Solution

We supplied the CTS0060N industrial cabinet air conditioner, specifically designed for energy storage applications.

Solution highlights:

6 kW cooling capacity
R-513A eco-friendly refrigerant
High-efficiency compressor for stable and energy-saving operation
RS485 communication for remote monitoring and intelligent control
IP56 protection level, suitable for harsh outdoor environments

The solution ensures precise temperature control and long-term reliability for BESS cabinets.

Installation & Results

The unit was installed vertically inside the BESS enclosure, enabling compact integration and efficient airflow design.

The first unit has been running stably under real operating conditions
The customer has moved to stable monthly orders of 10 units
Overall feedback has been highly positive, confirming system stability, performance, and reliability

This project demonstrates a proven and scalable cooling solution for U.S. commercial BESS applications.
