Power inverters play an important role in solar energy systems by converting direct current (DC) electricity into alternating current (AC). They make solar-generated electricity suitable for household appliances, commercial equipment and grid-connected applications. In India, applicable power inverters must comply with the relevant Bureau of Indian Standards (BIS) requirements before being placed on the market.
BIS Certification for Power Inverters helps manufacturers demonstrate that their products meet the prescribed safety and performance requirements. It also supports regulatory compliance and builds confidence among customers, distributors and business partners.
Why Is BIS Certification Required for Power Inverters?
Power inverters handle electrical energy and operate under different load conditions. Poor product quality or inadequate safety protection can create risks such as electric shock, overheating, equipment damage and electrical failure.
BIS certification establishes a standardised framework for evaluating product safety and performance. Manufacturers and importers should identify the applicable Quality Control Order (QCO) and product standards before starting the registration process.
Applicable BIS Standards for Power Inverters
Under the applicable solar product requirements, power inverters are subject to specific Indian Standards.
The important standards include:
-
IS 16221 (Part 2):2015: Covers safety requirements for power converters used in photovoltaic systems.
-
IS/IEC 61683:1999: Provides procedures for measuring the efficiency of photovoltaic power conditioners.
-
IS 16169:2019: Covers the islanding prevention test procedure for utility-interconnected photovoltaic inverters.
-
IS 17980:2022: Covers MPPT efficiency measurement for grid-connected photovoltaic inverters.
The applicable combination depends on whether the product is a standalone or utility-interconnected inverter.
BIS CRS Registration for Power Inverters
BIS CRS Registration for Power Inverters is generally processed under the Compulsory Registration Scheme (CRS), also known as Scheme II, where applicable.
Unlike the ISI certification route, CRS primarily involves product testing at a BIS-recognised laboratory, submission of technical documents and verification by BIS.
Manufacturers must ensure that their products comply with the relevant standards before applying. After successful verification and registration, the manufacturer can use the applicable BIS Standard Mark according to the registration conditions.
BIS Certification Process for Power Inverters
The certification process generally involves the following steps:
-
Identify Applicable Standards: Determine the correct Indian Standards based on the inverter type and intended application.
-
Product Testing: Submit product samples to an appropriate BIS-recognised laboratory for testing.
-
Prepare Documents: Arrange technical specifications, factory details, test reports and other required documents.
-
Online Application: Submit the registration application through the BIS online portal.
-
BIS Verification: BIS examines the application and supporting test reports.
-
Registration Approval: After successful verification, BIS grants registration with the applicable registration number.
Manufacturers should also ensure that product models included in the application meet the applicable testing and grouping requirements.
Role of a BIS CRS Consultant for Power Inverters
Working with a BIS CRS Consultant for Power Inverters can make the certification process more organised. A professional consultant helps manufacturers understand the applicable standards, prepare technical documentation and coordinate product testing.
A BIS Consultant for Power Inverters can also assist with application preparation, identifying documentation gaps and responding to regulatory queries during the registration process.
For foreign manufacturers, appointing an eligible Authorized Indian Representative (AIR) is an important part of the CRS application process.
