Frequently Asked Questions (FAQ)
1、What Is an Energy Storage Container?
An energy storage container is a modular solution that integrates battery systems, power conversion equipment, thermal management, and safety monitoring systems within a standard container. Designed for flexibility and easy deployment, the BESS container offers a compact and efficient way to store and manage energy for various applications.
2、What Certifications Do Your Products Have?
Our energy storage containers have obtained multiple international and industry certifications, including IEC 60529, IEC 60730, IEC 62619, IEC 62933, IEC 62477, IEC 63056, IEC/EN 61000, UL 1973, UL 9540A, UL 9540, CE Marking, UN 38.3, TÜV, DNV, NFPA69, and FCC Part 15B, ensuring safety and reliability.
3、How Long Do the Batteries in Your Energy Storage Container Last?
Designed for long service life, with a 10-year warranty under standard operating conditions.Supported by dedicated engineering and lifecycle service teams.
4、Can I Customize the BESS for My Specific Grid Requirements?
Yes, our modular design allows flexible configuration to match your load, frequency regulation, and renewable integration needs.
5、Can the BESS Support Different Grid Voltages and Frequencies?
Yes — the Grid-Tied Version of our Turtle CL2.5 Series supports multiple AC voltage platforms (400V / 690V / 800V) at 50/60Hz. The Off-Grid and On/Off-Grid Switching versions are rated at 400V, 50/60Hz.
6、Is the System Compatible with Third-Party Inverters or PCS?
Our containerized BESS can be configured to integrate with third-party inverters and PCS equipment, supporting multi-brand system integration for projects with existing infrastructure.
7、Does the Containerized BESS Support Automatic On/Off-Grid Switching (STS/ATS)?
Yes — this is built into the On/Off-Grid Switching Version of our Turtle CL2.5 Series, which integrates STS (1000kW) with optional ATS (1000kW), enabling seamless switching between grid, storage, PV, and diesel generator. This is specific to this product variant rather than an add-on available across all container configurations.
8、Is There a Minimum Order Quantity for Customized Configurations?
We support both large-scale utility projects and smaller customized orders. Specific MOQ depends on the configuration complexity — our engineering team can confirm this based on your project scope.
9、Do You Have Local Support Outside of Europe?
Yes. Beyond our Europe service centers and warehouse (Netherlands, Germany, Poland), Wenergy also maintains a global subsidiary presence, including Austin, USA, backed by an R&D and production base in China.
