Mnre specification for solar inverter

What are the MNRE guidelines for solar inverters?

Image: Sungrow Power Supply Co Ltd. The MNRE guidelines cover solar inverters having maximum DC voltage of 1000/1100V and nominal AC voltage of 415V. Inverters rated 1100V DC will be tested at 1000V. As solar inverters are of varying sizes, ratings, varieties, etc, these are to be grouped before submitting samples to test labs.

Are solar PV inverters BIS certified?

India’s Ministry of New & Renewable Energy (MNRE) has issued guidelines for solar PV inverter manufacturers to get their products tested and approved by Bureau of India Standards (BIS) certified labs. These guidelines apply to off-grid, grid-tie and hybrid inverters of capacities up to 150 KW.

What does MNRE stand for?

The Ministry of New and Renewable Energy ( MNRE) has issued draft guidelines for standards regarding the technical specifications for solar grid-tied inverters. The Ministry has invited comments and inputs from the public and stakeholders by April 30, 2020.

Should the MNRE series guidelines be referred to?

The draft added that the MNRE series guidelines should be referred to for selecting the samples from a single family of inverters. In August 2019, the MNRE had approved the series guidelines for grouping solar inverters.

What are the requirements for a solar PV module?

The PV module should have crystalline silicon solar cells and must have a certificate of testing conforming to IEC 61215 Edition II / BIS 14286 from an NABL or IECQ accredited Laboratory. The power output of the module(s) under STC should be a minimum of 100 Wp at a load voltage* of 16.4 ± 0.2 V. Vnom 12V.

What are the laws governing solar power inverters in India?

It prohibits sales, import or distribution of goods that do not conform to specified Indian standards —IS 16221 (Part 2): 2015 (Safety of Power Converters for use in Solar Photovoltaic Power Systems) and IS 16169:2014 (Test Procedure of Islanding Prevention Measures for Utility-Interconnected Photovoltaic Inverters) in the case of PV inverters.
