Battery Energy Storage Systems (BESS) are critical to the clean energy transition, but ensuring their safety and compliance requires more than just good engineering. Certifications like CE for BESS is one of the most recognized marks in Europe, confirming that a product meets essential health, safety, and environmental standards. However, while CE is necessary for entering the EU market, it does not always guarantee complete system-level safety. To build global trust, manufacturers often combine CE with other certifications such as UL and IEC, ensuring stronger compliance, reliability, and market acceptance.
What Does CE Certification Mean for BESS?
The CE mark (Conformité Européenne) is a mandatory certification for products entering the European Economic Area (EEA). For BESS, CE shows compliance with EU directives and harmonized standards.
When a BESS carries the CE mark, it declares conformity with the following directives:
- Low Voltage Directive (LVD) – Protects against electrical hazards.
- Electromagnetic Compatibility (EMC) Directive – Prevents electrical interference.
- Restriction of Hazardous Substances (RoHS) – Limits toxic chemicals in batteries and components.
- General Safety Directives – Cover risks related to machinery and consumer use.
In essence, CE for BESS confirms that the system has met basic EU safety and environmental requirements, allowing it to be legally marketed and installed in Europe.

- National standards guarantee local approval, allowing sales in markets like India, Japan, or Korea.
Therefore, CE should be seen as the foundation, while UL, IEC, and national approvals are the reinforcements. Together, they create a safe and credible BESS product.
Why Companies Should Go Beyond CE for BESS
Although CE is attractive for cost and speed, relying on it alone can lead to challenges:
- Limited Market Reach: CE only works in Europe, not globally.
- Lower Buyer Confidence: Utilities and large clients often demand UL or IEC reports.
- Safety Risks: CE’s self-declaration model may overlook thermal runaway or fire propagation risks.
- Regulatory Pressure: More countries are adopting stricter BESS safety laws.
Companies that invest in full certification portfolios gain stronger market access, brand reputation, and customer trust.
Conclusion: CE is Essential but Not the Final Step
CE for BESS is a mandatory starting point for European market access. It ensures compliance with basic safety, EMC, and environmental standards. However, CE is not enough to prove the full safety of complex battery energy storage systems.
Most companies choose CE because it is fast, affordable, and easy, but long-term success requires additional certifications like UL 9540, IEC 62619, and BIS. These provide independent validation, global acceptance, and higher safety assurance.
In the evolving energy landscape, BESS manufacturers and project developers must go beyond CE certification to build trust, reliability, and international growth opportunities.
