BIS Certification for Power Converters for Use in Photovoltaic Power Systems

As the demand for renewable energy sources increases, photovoltaic (PV) power systems are becoming more popular for both residential and commercial applications. Power converters are essential in these systems, as they ensure efficient energy conversion and stable operation. In India, obtaining BIS certification for power converters is mandatory to ensure safety, performance, and regulatory compliance.

Introduction to CRS Certification for Power Converters

The Bureau of Indian Standards (BIS) has introduced the Compulsory Registration Scheme (CRS) to regulate electronic and IT products, including power converters used in photovoltaic (PV) systems. The BIS CRS for power converters ensures that these products meet essential safety and performance standards, thereby reducing risks such as electric shocks, overheating, and electromagnetic interference.

Manufacturers are required to comply with the Indian Standard for power converters, specifically IS 16221 (Part 2): 2015, which is aligned with IEC 62109-2: 2011. These standards establish stringent safety requirements for power converters, ensuring their reliability under various environmental conditions.

Why is BIS Registration for Power Converters Necessary?

CRS certification is essential for power converters for several reasons. 

  1. Ensuring Electrical Safety: BIS certification protects end-users from electrical hazards such as short circuits, over-voltage, and over-current risks.
  2. Compliance with National and International Standards: By adhering to Indian Standards for power converters, manufacturers demonstrate their commitment to safety and quality, ensuring compliance with both national and international regulations.
  3. Market Credibility and Consumer Trust: Certified products have a competitive advantage, as BIS registration assures consumers of the reliability and efficiency of power converters.
  4. Regulatory Compliance for Market Entry: BIS registration for power converters is a mandatory requirement for manufacturers seeking to enter the Indian market, making compliance essential for business expansion.

Overview of Indian Standard IS 16221 (Part 2): 2015 and IEC Standards for Power Converters

Indian Standard IS 16221 (Part 2): 2015 and IEC 62109-2: 2011 specify essential safety and performance criteria for power converters used in photovoltaic power systems. These standards ensure that converters operate efficiently while minimizing risks related to electrical safety, such as shocks and overheating. The standards include specifications for electrical safety, performance requirements, and testing procedures. By adhering to these standards, manufacturers demonstrate their commitment to quality and safety, enhancing product credibility and facilitating regulatory compliance.

Tests Performed

To obtain BIS certification for power converters, manufacturers must undergo comprehensive testing to ensure product safety and performance. The key tests include:

  • Electrical Safety Tests – Verifies insulation resistance and protection against electric shocks.

  • Performance Testing – Evaluates energy conversion efficiency and operational stability.

  • Thermal Tests – Assesses heat dissipation and protection against overheating.

  • Load Testing – Checks the performance under variable loads.

  • Environmental Testing – Ensures durability under different temperature and humidity conditions.

  • EMC Testing – Confirms that the converter does not interfere with other electronic devices.

BIS Registration Process for Power Converters

The BIS registration process differs slightly for domestic and foreign manufacturers but broadly follows these steps:

For Foreign Manufacturers:

  1. Nominate an Indian Representative: In order to get FMCS Certification, a foreign manufacturer must appoint an Indian Representative with a valid business presence in India to handle the registration process.
  2. Online Application Submission: The representative submits an application via the BIS portal, ensuring all details are accurate.
  3. Sample Testing: Power Converters samples are tested in a BIS-approved laboratory for compliance with IS 16221 (Part 2): 2015.
  4. Submit Complete Application: The application, along with test reports and required documents, is submitted online or in hard copy.
  5. BIS Verification: The BIS reviews documents and may conduct factory inspections.
  6. Grant of License: Upon successful verification, the BIS grants a license, allowing the use of the CRS mark.

For Domestic Manufacturers:

  1. Submit Online Application: Domestic manufacturers directly apply on the BIS portal to begin the registration process.
  2. Sample Testing: Like foreign manufacturers, samples are tested at a BIS-recognized lab.
  3. Submit Application: A complete application, including test reports, is submitted to the BIS.
  4. Verification: The BIS reviews documents and may inspect the manufacturing facility.
  5. License Grant: After successful verification, the BIS issues a license for using the CRS mark.
