A few months ago, during a discussion with an overseas distributor, someone asked a question that many companies in the energy storage industry eventually face:<\/p>\n

“What certifications are required if we want to import residential energy storage systems from China?”<\/strong><\/p>\n

At first glance, a home battery system looks relatively simple. It stores electricity, supports solar power usage, and provides backup energy. However, once you start preparing for international markets, the situation becomes more complex.<\/p>\n

Different regions have different regulatory frameworks, safety standards, and transportation requirements. From our experience working with international partners at KRL Energy<\/strong>, certification is often one of the biggest barriers for manufacturers entering overseas markets.<\/p>\n

This article provides a practical overview of the key certification systems required when exporting residential energy storage systems.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Residential energy storage has become one of the fastest-growing sectors in the global renewable energy industry.<\/p>\n

The reasons behind this growth vary across regions.<\/p>\n

In Europe and North America<\/strong>, high electricity prices are a major driver. Many households install solar panels together with battery storage systems in order to store solar energy during the day and use it when electricity prices are highest.<\/p>\n

In Southeast Asia and parts of Africa<\/strong>, the motivation is different. The primary issue in these regions is grid reliability. Power outages and unstable electricity supply make residential battery systems valuable as backup power solutions.<\/p>\n

Because of these different applications, safety standards and certification requirements have become increasingly important for manufacturers.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

For Chinese manufacturers, overseas markets represent the main opportunity for residential energy storage expansion. However, entering these markets requires compliance with strict certification systems.<\/p>\n

The most common certification frameworks include:<\/p>\n

\n
\n\n\n\n\n\n\n\n\n
Region<\/th>\nCertification System<\/th>\n<\/tr>\n<\/thead>\n
North America<\/td>\nUL Certification<\/td>\n<\/tr>\n

Australia<\/td>\nCEC Certification<\/td>\n<\/tr>\n
Japan<\/td>\nJIS Certification<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

In addition to product certification, energy storage batteries must also comply with transportation safety regulations<\/strong>, especially when shipped internationally.<\/p>\n

These include requirements such as UN38.3 testing and transport appraisal reports<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

For companies entering the United States or Canadian market<\/strong>, UL certification is typically essential.<\/p>\n

In most residential energy storage projects we have worked on at KRL Energy<\/strong>, three UL standards appear most frequently.<\/p>\n

UL 9540 – Energy Storage System Safety<\/h3>\n

UL 9540 evaluates the safety of the entire energy storage system rather than individual components. This includes the battery pack, inverter, and system integration.<\/p>\n

Testing focuses on electrical safety, mechanical integrity, and environmental reliability to ensure that the full system operates safely under real-world conditions.<\/p>\n

\n

UL 9540A – Thermal Runaway and Fire Testing<\/h3>\n

UL 9540A focuses specifically on thermal runaway events and fire propagation risks<\/strong>.<\/p>\n

The test evaluates how a battery system behaves during extreme thermal conditions. Installation spacing, ventilation design, and fire mitigation strategies are all considered.<\/p>\n

Thermal management design often plays a critical role in passing this test.<\/p>\n

\n

UL 1973 – Lithium Battery Safety<\/h3>\n

UL 1973 focuses on stationary lithium battery systems used in energy storage.<\/p>\n

The testing process includes combustion testing, overcharge protection tests, over-discharge testing, and temperature shock simulations to verify that battery systems remain safe under extreme conditions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

CE Certification for the European Market<\/h2>\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

For companies exporting energy storage systems to Europe, CE certification is mandatory<\/strong>. In practice, CE compliance involves several related technical standards.<\/p>\n

IEC \/ EN 62619 – Battery Safety<\/h3>\n

This standard focuses on lithium battery safety and includes testing such as:<\/p>\n

    \n
  • external short circuit testing<\/li>\n
  • impact testing<\/li>\n
  • drop testing<\/li>\n
  • thermal abuse testing<\/li>\n
  • overcharge testing<\/li>\n
  • forced discharge testing<\/li>\n<\/ul>\n

    The standard also evaluates the battery management system (BMS)<\/strong>, including protection functions for over-voltage, over-current, and temperature control.<\/p>\n

    \n

    IEC \/ EN 62477 and IEC \/ EN 62109 – PCS Safety<\/h3>\n

    These standards apply to power conversion systems (PCS)<\/strong> used in energy storage installations.<\/p>\n

    They evaluate protection against electric shock, fire hazards, thermal risks, mechanical hazards, and operational safety under various environmental conditions.<\/p>\n

    \n

    VDE 2510 – German Market Standard<\/h3>\n

    Germany has one of the most developed residential storage markets in Europe. For this reason, additional certification such as VDE 2510<\/strong> is often required.<\/p>\n

    This standard covers areas including battery safety, electromagnetic compatibility, installation safety, and grid connection requirements.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    \n\t\t\t\t\t

    \n\t\t\t\t\t
    \n\t\t\t\t
    \n\t\t\t\t\t\t\t\t\t

    In addition to product certification, lithium batteries used in energy storage systems must comply with transportation safety regulations.<\/p>\n

    UN38.3 Lithium Battery Test<\/h3>\n

    UN38.3 is a globally recognized safety standard for lithium battery transportation.<\/p>\n

    Testing includes altitude simulation, temperature cycling, vibration testing, shock testing, external short circuit tests, overcharge tests, and forced discharge testing.<\/p>\n

    These procedures ensure that lithium batteries remain safe during transportation by air, sea, or land.<\/p>\n

    \n

    Air and Sea Transport Appraisal Reports<\/h3>\n

    For battery products shipped from mainland China, transportation appraisal reports must be issued by authorized dangerous goods testing institutions approved by the Civil Aviation Administration of China (CAAC)<\/strong>.<\/p>\n

    These reports confirm that battery products meet aviation and maritime transport safety requirements.<\/p>\n

    \n

    A Practical Lesson from a KRL Energy Project<\/h2>\n

    During one export project we worked on last year, we initially assumed the battery modules would easily pass certification testing.<\/p>\n

    However, during the thermal evaluation stage, the system did not pass the first test.<\/p>\n

    Interestingly, the battery cells themselves were not the problem. The issue was related to the airflow design inside the battery enclosure<\/strong>.<\/p>\n

    After modifying the ventilation structure and improving heat dissipation pathways, the system successfully passed the thermal safety test.<\/p>\n

    Experiences like this show that certification is not simply a documentation process. In many cases, certification requirements influence the engineering design of the entire system<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    Exporting residential energy storage systems involves much more than manufacturing reliable battery hardware. Companies must also understand international certification frameworks, safety regulations, and transportation requirements.<\/p>\n

    From our experience at KRL Energy<\/strong>, manufacturers that integrate certification planning into the early stages of product design are able to enter global markets much more efficiently.<\/p>\n

    As residential energy storage continues to expand worldwide, compliance and safety will remain essential factors for long-term success.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
