Scheduled from 18th to 20th September at the India Expo Center, Greater Noida, the 12th edition of Renewable Energy India Expo (REI) is all set to come back in a magnificent way this year. As a global smart PV leader, Huawei has rich experience in such digital technologies as cloud computing, artificial intelligence (AI), Big Data, and IoT. In this exhibition, Huawei unveiled its latest smart PV solutions, and shared with global customers the successful experience and methods in new energy digitization.
Based on reports released by global consultancies IHS Markit, Huawei was ranked No. 1 globally in inverter shipments for three consecutive years, 2015 – 2017. According to the latest Utility Solar Map released by Bridge to India, an Indian authoritative consulting firm, the grid-connected capacity of Huawei utility-scale PV plants ranks No.1 from October 2017 to September 2018, and FusionSolar Smart PV Solution has been widely recognized by Indian customers.
Following the digitization trend, Huawei displayed the global leading smart PV series solutions under the theme “Roads to a Digital PV World”, including Utility Smart PV Solution, Commercial Smart PV Solution, Floating Smart PV Solution, and one-click O&M Smart I-V Curve Diagnosis, and FusionSolar Smart PV Management System.
In 2018, Huawei launched the optimal LCOE solution – Smart DC System, by drawing on the practical experience of more than 100MW PV plants around the world and the studies on the practice test data of empirical bases. The Smart DC System matches the mainstream star product SUN2000-95KTL string inverter. With an efficiency of up to 99%, the SUN2000-95KTL supports 66MPPT circuits/MW. Protected to IP65, it is not configured with fuses and other vulnerable parts. Additionally, the system integrates the bifacial module, smart solar tracker, and the smart PV inverter through the smart chip and AI algorithm. It enables customers to take the lead in the age of intelligence.
With a maximum input current of 25 A for each MPPT circuit, the SUN2000-95KTL fully meets the requirements of increasing the output current for bifacial modules. Multiple MPPT circuits minimize the mismatch loss caused by bifacial modules. The most efficient MPP intelligent tracking algorithm in the industry is adopted to improve the energy yield of bifacial modules. The tracker management system is integrated to intelligently adjust the operating status of solar trackers, and added with the intelligent adjustment mode of “strong wind, heavy snow, and heavy rain”.
Black Technology: Smart I-V Curve Diagnosis
The Smart I-V Curve Diagnosis introduced in this exhibition is developed through AI. With the help of the Smart PV Management System and the smart PV controller (inverter), you can enable the Smart I-V Curve Diagnosis function remotely by one click, and perform the full diagnosis of each PV string online rapidly.
The function enables the system to quickly identify and locate problems in the early stage of energy yield loss, and reminds users to replace the faulty parts in a timely manner, minimizing the energy yield loss and safeguarding investors’ revenues. No professional personnel or device is required. Based on the I-V curve, the system automatically analyzes the fault cause, identifies the faulty string, and automatically generates a diagnosis report. The system can also perform a full intelligent diagnosis online for multiple scenarios and PV modules. The actual project application has exceeded 3 GW.
In addition, the brand new Floating Smart PV Solution and Commercial Smart PV Solution perfectly match the Indian PV market scenarios and customer requirements, therefore attracting a large number of customers. India enjoys sufficient sunlight, and has a huge potential in the PV market. By the end of 2017, the total PV plant installation capacity in India had been estimated to be 20 GW. According to Huawei technical experts, Huawei PV inverters, with no vulnerable components such as fuses, are more reliable and have a fault rate of 1/10 of the industry level. The inverters perfectly meet the actual requirements of Indian PV plants, and have been applied in lot of harsh environments with high salinity and high humidity. Currently, the capacity of the inverters operating stably in such environments amounts to 75 GW.
