POWER-INVERTERS-FOR-USE-IN-PHOTOVOLTAIC-POWER-SYSTEM

Power inverters are essential devices that convert direct current (DC) into alternating current (AC), enabling the use of electricity from renewable or stored energy sources like batteries and solar panels.

To ensure their safe performance, reliability, and compliance with Indian safety standards, the Bureau of Indian Standards (BIS) has made it mandatory for power inverters to be registered under IS 16221 (Part 2):2015 / IEC 62109-2:2011.

This standard lays down the safety requirements for inverters used in photovoltaic and other power conversion systems, focusing on protection against electrical, mechanical, and thermal hazards. It ensures that the product operates safely under normal and fault conditions, minimizing the risk of shock, fire, or injury.

Manufacturers and importers must obtain BIS Registration before selling or distributing power inverters in the Indian market. The process involves product testing in a BIS recognized laboratory followed by registration through the Compulsory Registration Scheme (CRS).

Essential Guidelines for Securing BIS Certification in India

Obtaining BIS Certification in India is a crucial step for manufacturers aiming to sell electronic and electrical products legally within the country. The Bureau of Indian Standards (BIS) ensures that only safe, high quality, and compliant products reach the Indian market. To successfully acquire BIS registration, manufacturers must fulfill four fundamental criteria.

Manufacturer Requirement: BIS licenses are granted exclusively to manufacturers. While importers can represent foreign companies during the application process, the certification is officially issued in the manufacturer’s name. This ensures accountability, product integrity, and compliance with India’s strict safety and quality regulations.

Verified Manufacturing Location: Providing an accurate manufacturing address is mandatory. If a manufacturer operates multiple facilities producing the same product, each site requires a separate BIS license. This verification guarantees traceability and regulatory compliance, allowing authorities to monitor production standards efficiently.

Product-Specific Registration: Each unique product must have its own BIS registration. However, multiple models falling under the same product category can be grouped under a single license. This approach ensures all product variations comply with the required technical and safety standards without unnecessary duplication of certifications.

Brand or Trademark Compliance: Every distinct brand or trademark used for a product must obtain a separate BIS license. This protects consumers by ensuring that every product sold under a brand name meets the prescribed safety, performance, and quality norms.

Compliance not only allows manufacturers to enter the Indian market confidently but also builds consumer trust, brand credibility, and regulatory reliability, essential for long-term business success.

How to Get BIS Certification in India?

The steps to acquire BIS certification for POWER INVERTERS IS 16221 (Part 2):2015 / IEC 62109-2:2011 may differ based on the manufacturer’s location, with separate guidelines for domestic and foreign manufacturers.

Steps	Foreign Manufacturer Process	Domestic Manufacturer Process
STEP:1	Appoint an Indian Authorized Representative to act on behalf of the foreign manufacturer.	Start the online BIS test request process directly as the manufacturer.
STEP:2	Complete the online submission on the BIS portal.	Conduct sample testing at a BIS approved laboratory for compliance verification.
STEP:3	Arrange sample testing at a BIS recognized laboratory to ensure product meets Indian standards.	Submit the application along with the sample test report through online channels.
STEP:4	Submit the online application, including the sample test report.	BIS Officials review and verify the application and supporting documents.
STEP:5	BIS review: Officials assess the application, documentation, and sample test results.	License approval: BIS grants the certificate if all requirements are fulfilled.
STEP:6	Grant of Licence

Nomination of AIR for foreign manufacturers

For foreign manufacturers aiming to sell electronic or electrical products in India, appointing an Authorized Indian Representative (AIR) is a mandatory step under the BIS Compulsory Registration Scheme (CRS). The AIR acts as the official point of contact between the foreign manufacturer and BIS, ensuring smooth application submission, sample testing, and regulatory compliance.

The Appointment of an Authorized Indian Representative (AIR) follows a structured hierarchy:

Clause 1	If the foreign company maintains a liaison or branch office in India, that office automatically serves as the AIR, acting as the official point of contact with BIS authorities.
Clause 2	When no liaison or branch office exists in India, the Indian proprietor or registered owner of the brand or trademark displayed on the product assumes the role of AIR, ensuring compliance with BIS CRS regulations.
Clause 3	In cases where there is neither an office nor an Indian brand owner, a designated Indian entity must be appointed as the AIR to manage all BIS related procedures, including application submission, sample testing, and coordination with BIS officials.

Top Considerations Before Submitting Your BIS Application

1. Choose a BIS Recognized Testing Laboratory and Trusted Compliance Partner

Always select a BIS approved testing laboratory and collaborate with an experienced compliance partner in India. This ensures accuracy in documentation, testing, and communication with the Bureau of Indian Standards.

2. Verify Laboratory Accreditation and Status

Confirm that the chosen lab’s BIS license is valid and active. Avoid sending samples to a lab undergoing or awaiting audit to prevent delays in certification.

3. Plan Safe and Complete Sample Shipment

Ensure proper packaging, documentation, and logistics for your product samples right from dispatch to safe delivery at the BIS-recognized testing laboratory.

4. Accurate Completion of CDF and CCL Forms

Fill the Construction Data Form (CDF) with correct product specifications and the Critical Component List (CCL) with precise component details to avoid discrepancies during verification.

5. Submit Valid Test Reports Within the Stipulated Time

Test reports are valid for 90 days from issuance. Make sure to submit them to the BIS before expiration. If delayed, a fresh product sample must be sent for retesting.

6. Prepare All Documents Prior to Testing

Keep every required document such as licenses, technical files, and authorization letter ,ready before initiating the sample testing process to ensure a smooth workflow.

7. Understand BIS Approval Timelines

Once all documents and test reports are submitted, BIS approval typically takes 15 to 30 days. However, depending on product complexity, it may extend up to 60 days for final registration.

8. Authenticate and Notarize All Documentation

All forms and supporting documents must be duly signed by the manufacturer, brand owner, and Authorized Indian Representative (AIR). Additionally, get them notarized and officially stamped to maintain legal authenticity.
