BEE Registration for
Grid-Connected Solar Inverter

BEE Registration for grid-connected solar inverters up to 100 kW capacity is officially mandatory in India under the Bureau of Energy Efficiency (BEE) Standards and Labelling (S&L) program. This regulatory framework operates under IS 17980:2022 / IEC 62891:2020, which establishes rigorous performance testing and efficiency benchmarks. Compliance is legally required for all single-phase (230 V AC) and three-phase (up to 415 V AC) non-storage grid-tied inverters sold or imported into the Indian market.

To ensure optimal performance and energy efficiency, obtaining BEE Certification for Grid-Connected Solar Inverters has become increasingly important under India’s regulatory framework. Due to rising energy demand and the shift towards renewables in India. This is in accordance with the Appliance Labelling and Compliance Regulations, 2026, which came into effect on 1st January 2026.

Key Highlights of the IS 17980:2022/ IEC 62891:2020 for Grid-Connected Solar Inverter

Testing Requirements for BEE Certification for Grid-Connected Solar Inverter

Testing must be performed at a National Accreditation Board for Testing and Calibration Laboratories (NABL)-accredited or BEE-approved laboratory to verify minimum efficiency performance standards (MEPS) in accordance with IS 17980:2022 / IEC 62891:2020. A valid Bureau of Indian Standards (BIS) safety certification under IS 16221-2:2015 is a strict prerequisite before applying for BEE registration.

• Conversion Efficiency Testing: Measures how efficiently the inverter converts DC power from the solar PV system into AC power.
• Static MPPT Efficiency: Evaluates how effectively the inverter tracks the maximum power point under defined steady-state operating conditions.
• Dynamic MPPT Efficiency: Assesses the inverter's ability to track changes in PV input and maintain efficient operation under varying conditions.
• Multiple MPPT Input Testing: Where an inverter has multiple independent MPPT inputs, the applicable measurements are performed for the intended input configurations.
• PV Simulator Testing: The required PV I/V characteristics are simulated during the measurement procedure to evaluate inverter performance under specified operating conditions.
• Grid Voltage Conditions: Testing is performed at the specified nominal grid voltage; any deviations are documented in the test report.

Step-by-Step BEE Star Rating Process for Grid-Connected Solar Inverter 

Both the producer and the importer must undergo a registration procedure to obtain the BEE Star Rating for Grid-Connected Solar Inverters.

• Product Verification: Ensure your product is eligible for Compulsory or Voluntary BEE Certification.
• Product Sampling: Send samples of your product to NABL-accredited laboratories.
• Product Testing: Your product shall be tested in the laboratory for performance (star rating) and safety (BIS).
• Document Collection: Collect all required documents, including the factory license, user manual, BIS license, and the manufacturing unit address.
• Brand/Company Registration: Your company/brand gets registered on the BEE website, and payment is made.
• Application Filing: The application will be filed online and offline, along with signatures on the documents.
• Document Evaluation: BEE officials will evaluate your application to ensure all submitted documents are in order.
• BEE Certification: Once all the requirements in the documents and application are fulfilled, BEE officials give you a BEE certificate.

BEE Registration Timeline, Validity & Renewal for Grid-Connected Solar Inverter

The BEE Registration process usually takes between 30 and 60 days (6 to 8 weeks total, including laboratory testing). International producers should send their application via an Authorised Indian Representative (AIR) or an Indian importer. The certificate will be issued for 3 years or for the validity period of the notification for the particular product.

Procedure for BEE Registration Renewal

Advance Notice: BEE provides an advance notice or renewal window a few months prior to the expiry date. 
Re-testing: Products need to be retested if any changes were made to the efficiency parameters in a certified lab accredited by NABL or approved by BEE.

• Online Application Submission: Access the BEE Portal for the renewal application submission. 
• Documentation and Fees: Provide updated technical documentation, production details, a new sample label design, and pay the required government processing fees. 
• Renewal: Upon verification, BEE reissues the certificate, granting permission to continue using the label.
