Energy Storage Power Supply IEC/EN 62477-1 Testing
For exporting home energy storage systems to the EU, CE certification and RoHS certification are primarily required. Based on the composition and functionality of the home energy storage system, the battery typically requires an EN 62619 report. For standard home energy storage systems: - CE-LVD requires compliance with the EN 62477 standard; - CE-EMC requires compliance with the EN 61000 standard. For photovoltaic-based home energy storage systems, CE-LVD requires compliance with EN 62109, while CE-EMC requires EN 61000. If wireless functionality (e.g., wireless charging) is present, CE-RED certification is required to assess the wireless component. ROHS compliance follows ROHS 2.0, with testing typically conducted per IEC 62321. Beyond CE and ROHS, batteries must also meet the requirements of the Battery Directive 2006/66/EC.
Inverter (Converter) Testing Standard IEC/EN 62477-1:
IEC/EN 62477-1:2012 is a general safety standard for power electronic converter equipment and systems. It primarily addresses requirements for protection against electric shock, energy hazards, fire, thermal injury, mechanical and noise hazards, as well as environmental stresses during operation, storage, and transportation. This standard replaces the traditional EN 50178:1997 standard for electronic equipment in power installations.
Safety of Power Converters for Photovoltaic Power Systems - IEC 62109
Photovoltaic inverters convert the direct current (DC) voltage generated by photovoltaic modules into alternating current (AC) voltage. This AC power can be fed back into commercial transmission grids or used in off-grid applications, making inverters the core component of photovoltaic power generation systems. As the product with the highest number of electronic and electrical components in a photovoltaic power plant, inverters are prone to failure and exhibit relatively poor reliability. Enhancing inverter reliability can significantly improve the overall reliability of the power plant, thereby substantially increasing the average annual power generation of photovoltaic power plants.
