This platform is for educational purposes only. It does not qualify or authorize users to work on battery energy storage systems. BESS equipment presents serious hazards and must only be serviced by properly trained, qualified, and authorized personnel in accordance with applicable codes, standards, OEM requirements, and site procedures.
Course Overview
This course compares three BESS manufacturers used by Stella – Sungrow, CATL with Power Electronics (PE) PCS, and CLOU. It covers architecture, installation and commissioning differences. Site walkthroughs of Sungrow and CATL/PE units are included.
Note: CLOU walkthrough video content will be added in a future course update.
By the end of this training, you will be able to:
- Identify the three functional layers of any BESS – BMS, PCS, and EMS – and describe the role each plays in a complete system
- Compare Sungrow, CATL/PE, and CLOU units
- Recognize the key physical components, site layout, and power conversion configuration of a Sungrow PowerTitan and a CATL/PE installation from a site walkthrough
The walkthroughs in this course were filmed at specific installations and reflect those sites’ configuration, equipment model, and wiring layout. Your site may differ.
Always check your site’s as-built drawings, your equipment’s O&M manual, and your company’s procedures before working on any system.
