POWER CONVERTERS FOR USE IN PHOTOVOLTAIC POWER SYSTEM  – IS 16221 (PART 2)

Power converters for use in photovoltaic (PV) power systems are devices that convert the DC power produced by solar panels into AC power that can be used by homes, businesses, and the utility grid. These converters are typically used in grid-tied PV systems, which are connected to the utility grid and can feed excess power back into the grid.

There are two main types of power converters used in PV systems: inverters and microinverters. Inverters are centralized devices that convert the DC power from multiple solar panels into AC power. Microinverters, on the other hand, are installed on each individual solar panel and convert the DC power from that panel directly into AC power.

The primary function of power converters in PV systems is to ensure that the AC power produced by the system is at the appropriate voltage and frequency for use by homes, businesses, and the utility grid. This requires sophisticated control algorithms that continuously monitor the voltage and frequency of the grid and adjust the output of the converter accordingly.

In addition to voltage and frequency control, power converters in PV systems also include a range of safety features to protect the grid and the equipment connected to it. These features typically include over-voltage protection, under-voltage protection, over-current protection, and ground-fault protection.

There are many different types of power converters available for use in PV systems, including string inverters, central inverters, microinverters, and power optimizers. Each type of converter has its own set of advantages and disadvantages in terms of cost, efficiency, reliability, and ease of installation.

It is important to consult with a qualified professional when designing and installing a PV system to ensure that the appropriate power converters are selected and that the system is designed and installed to meet all applicable regulations and standards.

In July 2013, the Bureau of Indian Standards (BIS) added several products under the Compulsory Registration Scheme (CRS). Power converters for use in photovoltaic power system was one of them. Under Scheme II of Schedule II, Power converters for use in photovoltaic power system gets BIS registered and assures that the product is of good quality and safe.

PREREQUISITES FOR OBTAINING BIS REGISTRATION -

Manufacturers - BIS license is issued to the manufacturer. importer or Trader are not eligible to get BIS license. An importer can be an Authorized Indian Representative (AIR) of a foreign manufacturer license will be issued to the Manufacturer.

1. Proprietor or registered user of the brand/trademark appearing on the article is located in India :

• The AIR will be the brand's or trademark's owner.

1. No proprietor /registered user of the brand/trademark appearing on the article, located in India :

• Other entity/Company will become the AIR.

EXPENSES INVOLVED IN OBTAINING BIS CERTIFICATE FOR POWER CONVERTERS FOR USE IN PHOTOVOLTAIC POWER SYSTEM  AS PER IS 16221 (Part 2) UNDER THE PRODUCT CERTIFICATION (SCHEME-II) OF BIS :

• In the certification process, product testing is the most important stage as it determines whether the quality of the product meets Indian standards.
• For the same purpose, investments in testing facilities are required to install test equipment for internal factory test laboratories.
• Apart from charges mentioned above in the table, we may ask you to pay/reimbursement for a Pre-Visit at your Factory Premises to ensure the conformity of your product as per the relevant Indian Standard & BIS guidelines for its BIS certification.
