To support the goal of achieving net-zero carbon emissions by 2050, renewable energy power generation equipment and energy storage systems are expected to be increasingly deployed not only at outdoor sites but also in indoor environments, including households and factories. As Power Conversion Systems (PCS) and Photovoltaic (PV) inverters are critical components for energy conversion, system control and stable operation of energy storage and solar photovoltaic systems, their safety and reliability are essential for protecting users and maintaining system stability. In view of these developments, the Bureau of Standards, Metrology and Inspection (BSMI) proposes to expand the mandatory inspection scope for PCS and PV inverters to cover models with a rated capacity not exceeding 360 kW. This measure is intended to strengthen product safety management, ensure consumer safety and enhance the safe and stable operation of renewable energy and energy storage systems. Applicants may choose either of the following two conformity assessment procedures: Registration of Product Certification (RPC) or Type-Approved Batch Inspection (TABI).
