BIS Registration for Utility-Interconnected Photovoltaic Inverters
Utility-interconnected photovoltaic inverters are used in solar power systems to convert DC electricity generated from solar panels into AC power that can be supplied to the electrical grid. These inverters are widely used in residential solar systems, commercial solar plants, industrial projects, and large-scale renewable energy installations. Since these devices are directly connected to the power grid, ensuring their safety, performance, and reliability is very important.
To maintain product quality and electrical safety, the Government of India has made BIS Certification for Utility-Interconnected Photovoltaic Inverters mandatory under the Compulsory Registration Scheme. Manufacturers must obtain BIS registration for utility-interconnected photovoltaic inverters before manufacturing, importing, or selling these products in India.
The certification is granted according to IS 16169: 2014, IS 16221 (Part 2): 2015, and IS 17980: 2022, which specify safety and performance requirements for photovoltaic inverters connected to the utility grid.
Indian Standards for Photovoltaic Inverters
Certification for photovoltaic inverters is based on multiple Indian Standards issued by the
Bureau of Indian Standards.
IS 16169: 2014
This standard specifies requirements for grid-connected photovoltaic inverters to ensure safe and reliable operation.
IS 16221 (Part 2): 2015
This standard defines safety requirements for power converters, inverter systems, and electronic power equipment.
IS 17980: 2022
This standard covers performance and safety requirements for modern photovoltaic inverter systems used in renewable energy applications.
These standards must be followed to obtain CRS Certification for Utility-Interconnected Photovoltaic Inverters and BIS License for Utility-Interconnected Photovoltaic Inverters.
Basic Requirements
There are four key factors on which a BIS Licence is based. Without fulfilling these requirements, an applicant cannot apply for BIS Certification/Registration in India. To obtain BIS registration, the following conditions must be met:
Manufacturer: The BIS licence is issued only to the manufacturer, not to traders, importers, or distributors. However, in the case of foreign manufacturers, an Authorized Indian Representative (AIR) can submit the application on their behalf. The final licence is always granted in the name of the manufacturer.
Manufacturing Location: The exact manufacturing address must be clearly mentioned in the application and supporting documents. If a manufacturer operates multiple production units for the same product, a separate BIS licence is required for each manufacturing location.
Product: BIS registration is granted product-wise. Each product category requires a separate licence. However, if a product has multiple models under the same category, one licence can cover all those models .
Brand or Trademark: Every brand name or trademark must have its own BIS licence. If the same product is sold under different brands, separate licences are required for each brand or trademark.
Importance of BIS Certification
Obtaining BIS Certification for Utility-Interconnected Photovoltaic Inverters is mandatory for manufacturers and importers.
Ensures Electrical Safety: Grid-connected inverters operate at high voltage, so certification ensures protection against shock, overheating, and electrical faults.
Maintains Product Quality: Compliance with IS 16169:2014, IS 16221 (Part 2):2015, and IS 17980:2022 ensures proper performance and durability.
Builds Market Confidence: Products with BIS Registration for Utility-Interconnected Photovoltaic inverters are trusted by solar developers, government projects, and consumers.
Tests Performed
Before obtaining BIS registration for utility-interconnected photovoltaic inverters, the products undergo rigorous testing in BIS-recognized laboratories. The key tests include:
| Electrical Safety Tests | Evaluates insulation resistance and protection against electric shocks. |
| Protection of Equipment Users | It refers to safety measures and standards designed to protect people from potential hazards while using electrical, electronic, or mechanical equipment, ensuring the products are safe and reliable for use |
| Performance Testing | Ensures safe connection with utility power supply. |
| Environmental Testing | Tests the device’s durability under different temperature and humidity conditions. |
BIS Registration Process for Utility-Interconnected Photovoltaic Inverters
The BIS registration process differs slightly for domestic and foreign manufacturers but broadly follows these steps:
| For Foreign Manufacturers | For Domestic Manufacturers |
| Nominate an Indian Representative: A foreign manufacturer must appoint an Indian Representative with a valid business presence in India to handle the registration process for CRS Registration. | Submit Online Application: Domestic manufacturers directly apply on the BIS portal to begin the registration process. |
| Online Application Submission: The representative submits an application via the BIS portal, ensuring all details are accurate. | Sample Testing: Like foreign manufacturers, samples are tested at a BIS-recognized lab. |
| Sample Testing: samples are tested in a BIS-approved laboratory for compliance | Submit Application: A complete application, including test reports, is submitted to the BIS. |
| Submit Complete Application: The application, along with test reports and required documents, is submitted online or in hard copy. | BIS Verification: The BIS reviews technical and KYC documents. |
| BIS Verification: The BIS reviews technical and KYC documents. | License Grant: After successful verification, the BIS License for Utility-Interconnected Photovoltaic Inverters issues for using the BIS CRS mark. |
| Grant of License: Upon successful verification, the BIS grants a license, allowing the use of the BIS CRS mark. |
