BEE Registration for
Solid State Inverter

All inverters offered in the Indian market today comply with the quality and safety standards set by the Bureau of Energy Efficiency (BEE). The standards for Solid-state Inverters are laid down in IS 13314, which sets out the criteria that any manufacturer must meet to provide their products in the domestic market. As energy conservation has become increasingly important from the government's perspective, complying with these standards is no longer a mere ritual but an essential part of doing business successfully. Thus, it is necessary to register for the BEE Label on time.

Registration of the BEE Label for Solid-state Inverters in accordance with IS 13314 is included in Schedule 17 and is currently a voluntary star labelling program undertaken by the Bureau of Energy Efficiency (BEE). This category consists of Storage Battery Operated Inverters (Input Voltage: 12V DC; Output Power: 250VA to 2000VA Continuous).

Key Highlights of IS 13314 for State Inverter

Testing & NABL Lab Requirements under IS 13314

IS 13314 Inverter Testing needs NABL-accredited laboratories following ISO/IEC 17025 requirements to perform Bureau of Energy Efficiency (BEE) star ratings.

• Performance and Electrical Testing: Measurement of efficiency, total harmonic distortion (THD), voltage regulation, and losses under no-load & full-load conditions.
• Safety and Protective Tests: Tests for overload capacity, short-circuit protection, deep discharge cut-off voltage of batteries, and insulation resistance.
• Environmental and Climatic Testing: Tests for temperature rise, thermal stress and environmental enclosures (e.g. IP).
• Accreditation Scope: The laboratory's accreditation scope should include IS 13314, specifically in the electrical and power electronics testing category.
• Calibration and Traceability: Calibration certificates for all testing instruments used (e.g. power analysers, load banks and multimeters) should be traceable.
• Documentation Requirements: Laboratories must have a comprehensive Quality Manual, SOPs, an equipment register, and a test report format that includes the NABL logo.
• Sample Handling: Safe sample handling and a dedicated sample storage place for inverter and battery testing samples

Documents Required for BEE Registration (Solid State Inverter) 

The documents to be submitted are segregated below as follows:

• Application form for BEE
• Authorisation letter from the manufacturer, if any
• Documents for company registration
• Details of the manufacturing unit
• Technical specifications of the product
• Catalogue/brochure of the product
• Details of product model & rating
• Schematic diagram
• Test report from a laboratory accredited by NABL or recognised by BEE, as the case may be
• Test documents of Indian standard, if any
• Details of input and output ratings
• Energy efficiency or performance test data

BEE Registration Process for Solid State Inverter IS 13314

BEE Registration of a Solid State Inverter according to IS 13314 consists of checking the product requirements, performance testing using the specified laboratory test procedure, preparing documents, and submitting the application to the Bureau of Energy Efficiency (BEE).

• Product Classification: Check if the product is a Solid State Inverter.
• Phase and Rating Identification: Check if the product is single-phase or three-phase, and its power rating
• Standard Identification: Check the Indian Standard, such as IS 13314.
• Product Testing: Test of the Solid State Inverter for the required performance and efficiency parameters in the concerned laboratory
• Identification of Star Rating: Identification of the performance factor based on the BEE star rating requirement
• Documentation: Preparation of all the test reports, technical information, model number, etc.
• Application for Registration to BEE: Application for registration along with the documents under the BEE Standard & Labelling procedure
• Verification of Application by BEE: Verification of application by BEE with the concerned technical information
• Approval of Star Label: Approval of the required star label.

Validity, Renewal & Timeline of BEE Registration 

The validity period of Bureau of Energy Efficiency (BEE) registration for a solid-state inverter, as per IS 13314 and Schedule 17, is 3 years, provided the star rating remains unchanged during this period. To obtain BEE registration for a solid-state inverter, the complete procedure generally takes 30 to 45 working days.

The Bureau of Energy Efficiency (BEE) initiates the renewal process through its BEE Portal before the registration period expires.

• Response Period: The manufacturer/importer should respond and submit an initial expression of interest within 3 months of receiving the notice.
• Application: Log in to the website portal and enter the required company information, along with the total production/import quantity.
• Document Uploading: Upload the application documents with updated information demonstrating compliance with current energy efficiency norms.
• Payment of Fee: Pay the relevant renewal fee online.

How does ERCS Private Limited help in acquiring a BEE Registration consultant for a solid-state inverter?

ERCS Private Limited provides end-to-end regulatory and consultancy support to help manufacturers and importers secure Bureau of Energy Efficiency (BEE) registration and star-labelling compliance for electrical and power equipment, such as inverters. 

• Applicability test: We determine whether your inverter qualifies as either a generic solid-state inverter under Schedule 17 (IS 13314) or a new grid-connected solar inverter under the standards (IS 17980:2022 / IEC 62891:2020) that require BIS Certification under IS 16221-2:2015 before proceeding.
• Documentation preparation: We prepare the technical documentation, brand information and model information needed for submission under the BEE Standards & Labelling program.
• Coordination with NABL laboratories: We ensure sample testing is conducted in NABL-accredited laboratories and monitor test timelines to avoid unnecessary delays that could affect your registration process.
• Evaluation of test report: We evaluate the test results against BEE efficiency thresholds before filing the application to catch any issues that could lead to rejection.
• Filing and follow-up through the portal: We handle the entire submission process through the BEE online portal until approval is granted.
• Star banding & labelling: We help assign star ratings to your tested efficiency figures and ensure labelling is correct for future audits.
• Regulatory deadline monitoring: We help you stay ahead of regulatory changes, such as BEE’s new deadline for fresh submissions of grid-connected solar inverters by February 28, 2026, to avoid deactivation of existing model registrations.

Frequently Asked Questions (FAQs) for Solid State Inverter BEE Registration Certificate

Q1. Is BEE registration required for IS 13314 inverters?

Ans. BEE registration for general solid-state inverters (Schedule 17) is not yet required, but BEE certification has been made mandatory for grid-connected solar inverters up to 100 kW from January 1, 2026, under IS 17980:2022.

Q2. Which parameters are tested for inverter certification?

Ans. Inverter certification involves testing of conversion efficiency from DC to AC, power factor (at least 0.8 for resistive-inductive load conditions) and capacity, alongside structural, insulation and safety against electric shock under IS 13314.

Q3. Who can apply for BEE registration of solid-state inverters?

Ans. Manufacturers, importers and brand owners selling solid-state inverters in India can apply for BEE registration.

Q4. For how long is the BEE certificate valid?

Ans. The validity period of the Bureau of Energy Efficiency certificate is usually 3 years from the issuance date. However, it may be between 1 and 5 years depending on the particular product and notification scheme.
