BS EN 62920:2017+A11:2020

Overview

BS EN 62920:2017+A11:2020 is a crucial standard that outlines the electromagnetic compatibility (EMC) requirements and test methods for power conversion equipment used in photovoltaic (PV) power generating systems. As the demand for renewable energy sources continues to grow, ensuring the reliability and efficiency of PV systems is paramount. This standard provides a framework for manufacturers and compliance professionals to assess the EMC performance of their equipment, ensuring it meets both safety and operational requirements.

Key Requirements

The standard specifies a range of EMC requirements that must be adhered to in order to ensure the effective operation of power conversion equipment within PV systems. Key requirements include:

• Emission Limits: The standard sets limits on the electromagnetic emissions from power conversion equipment to prevent interference with other devices.
• Immunity Criteria: Equipment must demonstrate resilience against electromagnetic disturbances to maintain functionality in various environments.
• Testing Methods: Detailed testing methods are provided to evaluate compliance with the emission and immunity requirements, ensuring consistency and reliability in testing.
• Environmental Considerations: The standard takes into account the environmental conditions in which PV systems operate, ensuring that equipment is robust and reliable.

Implementation Benefits

Adopting BS EN 62920:2017+A11:2020 offers several practical benefits for manufacturers and compliance professionals:

• Enhanced Product Reliability: By adhering to the EMC requirements, manufacturers can ensure their products are less prone to failure due to electromagnetic interference.
• Market Access: Compliance with this standard can facilitate entry into various markets, as many regions require adherence to EMC standards for electrical equipment.
• Improved Customer Confidence: Demonstrating compliance with recognised standards enhances customer trust in product quality and performance.
• Streamlined Testing Processes: The standard provides clear testing methodologies, reducing ambiguity and improving the efficiency of compliance testing.

Compliance Value

Compliance with BS EN 62920:2017+A11:2020 is essential for manufacturers aiming to produce reliable and efficient photovoltaic power generating systems. The standard not only aids in meeting regulatory requirements but also serves as a benchmark for quality assurance. By ensuring that power conversion equipment meets the EMC criteria, manufacturers can mitigate risks associated with electromagnetic disturbances, thereby enhancing the overall performance and safety of PV systems.

Furthermore, compliance with this standard can lead to reduced liability and warranty claims, as products are less likely to malfunction due to EMC issues. This proactive approach to compliance can ultimately result in cost savings and improved market competitiveness.

In conclusion, BS EN 62920:2017+A11:2020 is a vital standard for the photovoltaic industry, providing essential guidelines for EMC requirements and testing methods. By implementing these standards, manufacturers can ensure their products are not only compliant but also reliable and efficient in the growing renewable energy market.
