Frequently Asked Questions (FAQ)
Q1: What does “PV-Storage-Diesel Integrated” mean, and how do the three power sources work together?
The Stars CL261Pro combines a 250kW PV input (10 strings), 261kWh battery storage, and a diesel generator interface within a single cabinet. It supports seamless switching between grid-connected and off-grid operation in under 10ms — in off-grid mode, PV, storage, and diesel work together to keep the load powered.
Q2: Can the system integrate with a diesel generator for backup power?
Yes. The CL261 PRO Backpack-type supports integrated PV-storage-diesel operation, with a rated diesel input capacity of 187kW. Compatibility with specific diesel generator configurations can be evaluated based on project requirements. For CL261STS configurations, the STS system includes a bypass breaker to support reliable power transfer between grid, storage, and load.
Q3: Is the CL261Pro cabinet suitable for EV charging stations, highway service areas, or parking lots?
Yes. The CL261Pro can be paired with external EV chargers, making it suitable for EV charging stations, highway service areas, parking lots, and PV-storage-charging applications. By integrating PV, battery storage, grid power, and diesel generator support, it can provide reliable power to external chargers and other site loads, while also supporting operation in locations with limited grid capacity or unstable grid supply.
Q4: What certifications does the Stars CL261Pro hold?
The Stars CL261Pro is certified to IEC/EN 62619, IEC 62477, IEC 60529, IEC 61000-6-2, IEC 61000-6-4, and UN38.3, supporting compliant deployment and transport in European and international markets.
