As the global energy transition accelerates, there is an intense demand for renewable energy worldwide. Industrial and commercial energy storage systems, which supplement energy with photovoltaic (PV) power and store electricity using solar energy—a green and renewable energy source—can stabilize the power grid and reduce electricity costs. The market demand for such systems is growing rapidly.
However, in the face of the highly competitive international market, especially the European Union (EU) with its strict regulations, ensuring that products comply with universal and authoritative CE certification standards is the "golden key" to unlocking and establishing a foothold in the European market.
1. LVD (Low Voltage Directive) Compliance Certificate
● Certification Standard: EN 62477-1:2012/A12:2021
● Core Meaning: Certifies that the energy storage cabinet has a safe electrical design under its operating voltage (380/400V AC, up to 936V DC), which can effectively prevent risks such as electric shock, energy surge, and fire for users or installers.
● Value: This is the most fundamental and important certificate for ensuring personal and equipment safety, and it is another mandatory requirement for the CE marking.
2. EMC (Electromagnetic Compatibility) Directive
Compliance Certificate
● Certification Standards: EN/IEC 61000-6-2, EN/IEC 61000-6-4
● Core Meanings:
● 61000-6-2 (Immunity to Interference): Certifies that the energy storage cabinet can resist external interference, operate stably, and not easily crash or restart in complex industrial electromagnetic environments.
● 61000-6-4 (Emission Limits): Certifies that the electromagnetic interference generated by the energy storage cabinet itself is extremely low, so it will not act like a "bad neighbor" and affect other sensitive equipment on the same power grid (such as precision instruments and communication systems).
● Value: This is a key proof of product reliability and stability, and it is one of the mandatory requirements for the CE marking.
3. IEC 62619 Industrial Energy Storage Battery Safety
Certificate
● Certification Standard: IEC 62619:2022
● Core Meaning: This is an authoritative safety standard specifically for industrial energy storage battery systems. It is much stricter than consumer battery standards and assesses the safety performance of batteries during long-term, high-load, and unattended operation in industrial environments, including:
① Functional safety of the Battery Management System (BMS) (overcharge, over-discharge, short circuit, and temperature control protection).
② Mechanical structure safety (e.g., impact resistance).
③ Thermal runaway protection.
● Value: This is one of the highest-level recognitions for the safety of the product’s "heart"—the battery system.
