What is BS EN 62109-2:2018?

BS EN 62109-2:2018 is a widely recognized technical standard that specifies the safety requirements for power converters in grid-connected photovoltaic (PV) systems. PV systems convert solar energy into electrical energy, and power converters play a critical role in this process by converting and regulating the generated electricity. The purpose of this standard is to ensure the safe operation and performance of these power converters.

Safety Requirements for Power Converters

One of the primary objectives of BS EN 62109-2:2018 is to establish safety requirements for power converters used in PV systems. These requirements include protection against electric shock, prevention of fire hazards, and mitigation of potential risks associated with system failures or malfunctioning. The standard outlines guidelines for insulation, mechanical design, temperature limits, and various protective measures that need to be implemented to ensure the safety of the converters.

Testing and Compliance

To ensure that power converters meet the safety requirements outlined in BS EN 62109-2:2018, testing and compliance procedures are defined in the standard. Manufacturers are required to subject their products to rigorous testing to verify their compliance with the specified safety measures. This includes testing for electrical insulation, resistance to abnormal environmental conditions, and thorough evaluation of protective features designed to safeguard both users and the electrical system.

Advantages of Using BS EN 62109-2:2018

The implementation of BS EN 62109-2:2018 brings several advantages to the PV industry and its stakeholders. Firstly, it ensures a higher level of safety, reducing the risk of accidents related to electric shock, fires, or other hazards. Secondly, the standard promotes uniformity in testing and compliance, providing manufacturers and users with a standardized framework for evaluating and comparing different power converters. Lastly, it enhances the overall quality and reliability of PV systems, contributing to the growth and acceptance of renewable energy sources.
