Ginlong Solis has been committed to technological innovation. From the 4G technology platform to the current 5G technology platform, our products are more abundant and the technology has also made great progress. The Indian market is one of the most active solar markets in the world. For the Indian market, we have also developed and applied many new technologies, such as technology for improving grid harmonics, active surge suppression technology and Class II SPD technology. Intelligent system diagnosis and String level monitoring technology, on Solis cloud platform. The application of these technologies is to better match the Indian power grid, installation environment and system management.

India's solar market has huge potential, both the government and the public are actively developing clean energy. Aiming at India's fast-growing industrial and commercial and ground power stations, we will bring new 5G products to the Indian market in 2020, including high-power 400VAC inverters such as 100kW, 110kW, and also 250kW such as 1500Vdc, 800VAC products for large power stations. In addition, we also planned off-grid systems for Industrial and Residential application where have more power cuts, off-grid system is independent power generator to cater such requirement.

We all now see technology upgradation one of the key things happening in the industry in all the directions, let’s just consider solar plant, PV module technologies is improving and also lot of new method are now adapted BOS, and most important components is solar inverter, which is also called as the heart of the plant. The solar inverter is  the one which provides all information of completely plant,  that only possible technology advancement in solar inverter to turn it into a smart Inverter which all together helps plant operator to know their plant, a smart Inverter can generate alarm, warning, which enable the plant operator to address the fault before it become permanent failure, and at the same time keeping Inverter operation to see if the threshold values are not crossing the limits by that not losing the full generations and allowing to run with best possible power which help to minimize loos of generation. We feel this advance will keep on happening in near future with solar inverter's, the overall goal is to minimize the downtime, take quick action in terms of O&M Activities, module cleaning, and also prediction of future fault that will help to operate the plant in more efficient manner.

Majorly we see advantage only with smart inverter as Inverter will able to show the very important information just in time whenever it needed or required, by that plant operator can take quick decision just in time to achieve overall goal of minimize down time and avoid loos of generation, which overall impact on revenue generations and also effect the ROI. Another advantage we see is that smart Inverter also safe to operate by a normal person,  there is no threat of human life,  easy to operate, and control, and also easy to carry out Inverter Maintenance, and in case of failure of inverter broken can be replaceable easily with less manpower.

Disadvantages we see is that inverter becoming super sensitive machine, at the same time level of advancement should need to use while commissioning the plant, the best installation practices need to follow, sometimes we see bad installation practise lead to Inverter malfunction as the solar inverter is too sensitive components which get trigger if see any changes in values, so. The important points is not just inverter to be smart also the EPC company, designer, installer also need to use right practice to make all together a better solar plant. As the plant need to function for next 20 to 25 years.
