Ginlong Technologies (Solis), a leading global manufacturer of solar photovoltaic (PV) string inverters has confirmed recieving the BIS certification for all its solar inverters in the country.

In August 2019, the Ministry of New and Renewable Energy (MNRE) had issued the guidelines for the series approval of solar PV inverters for conducting testing in test labs for the implementation of Quality Control Solar Photovoltaics Systems, Devices and Component Goods Order 2017.

The guidelines were meant to facilitate test labs/manufacturers to approve the product family including change in design and materials for the solar inverters for their compulsory registration with BIS and for the implementation of the solar photovoltaics systems order. And were applicable for solar PV based off-grid, grid-tied, and hybrid inverters of capacities up to 150 kW.

Under the guidelines, the manufacturers had to submit a declaration about the series of their products while submitting the samples of a particular series for testing to test labs. Out of the entire range of models intended to be covered under registration, the highest-rated model is being tested to cover the entire range of family.

The deadline for self-certification of solar inverters through the BIS has been extended a few times, and now Solis’s inverters have also made the grade for the certification.  

Last month, we had reported the firm was planning to raise over USD 100 million (~700 million Chinese Yuan), through a non-public offering to finance the expansion of its manufacturing capacity. Facing a rise in the global string inverter market, the firm announced that it would use the funds to double its production capacity of Solis products to 20 GW per year. 

The expanded factory will add 1,000,000 square feet to its existing facility in the Binhai Industrial park, bringing the company’s total capacity to 20 GW. Construction plans include a new state-of-the-art R&D center, high-volume production lines equipped with advanced automation machinery, increased warehousing capacity and new offices. A new corporate campus includes state-of-the-art offices, a multi-functional conference center and apartments for dedicated personnel.
