Recently, the Saudi energy navigation company ACWA Power completed the Oman IBRI two phase 500MW photovoltaic project financing, and once again launched a deep cooperation with the sun power, strong joint assistance to build the largest photovoltaic power station of Oman.
ACWA power pays special attention to the application of the latest technology route in this project, which requires the maximum reduction of lcoe; at the same time, it also puts forward high standard requirements for the reliability of equipment, so as to cope with the problems of Oman tropical desert climate, such as windy sand, strong wind erosion and large temperature difference. After comprehensive consideration, all customers finally choose the world's largest power 1500V series inverter SG250HX.
The world's largest single unit power + high capacity ratio, with the best system cost
SG250HX sets up the benchmark of the world's largest single unit power string inverter. With the same power station capacity, the number of inverters, low-voltage switchgear, cables and other equipment can be reduced. It is estimated that the initial investment cost of 100MW power station can be reduced zero point zero two Yuan / W or more. In addition, with the industry's higher volume ratio, support 6.75MW Large sub array design, PLC communication, integrated PID protection and repair functions and other advantages further reduce lcoe.
Intelligent air cooling + the highest level of protection, reliable operation in high temperature and strong sand environment

High temperature and strong wind sand are the strong enemies of reliable operation of the inverter. SG250HX adopts IP66 protection and C5 level anti-corrosion of the whole machine, with high sealing performance, no invasion of wind sand and water vapor, and adaptive strong corrosion environment. By adopting the industry-leading intelligent air cooling and heat dissipation technology, it can realize 50 ℃ full load without derating, reliable operation for more than 25 years, and reduce the risk of future use. Especially suitable for high temperature, strong wind and sand, strong corrosion and other extremely harsh environment.
Patent IV scanning makes operation and maintenance more efficient and labor-saving
The extreme environment also increases the difficulty of operation and maintenance of large-scale power stations, while the traditional inspection is time-consuming and inefficient, often suffering from "misdiagnosis" and "missed diagnosis", which is difficult to meet the requirements. As early as 2013, sungrow power took the lead in obtaining patent IV scanning technology. Through the verification of T 220V real station, one key start the whole station detection, online intelligent identification of 17 kinds of faults, and 15 minutes to obtain the health diagnosis report of 200mwp components, active operation and maintenance, simple and efficient, effectively solve the "misdiagnosis" and "missed diagnosis" problems of large-scale power station operation and maintenance, and win the best opportunity for fault handling.
"We are glad to cooperate with SUNGROW again. By providing the world's leading 1500V series inverter scheme and all-round localized services, we have solved many project problems for us and brought higher investment yield to our investors. We look forward to more cooperation in the future. " ACWA power Mr. rajit said in an interview.
As the world's most financing value inverter brand, solar power not only has its own brand in the field of clean power conversion technology, but also leads the world in the field of energy storage integration technology, continues to promote the "photovoltaic + energy storage" and economic development, and works together to solve the problem of photovoltaic grid friendliness and consumption.
By the end of 2019, sungrow power has accumulated over 100gw installed inverter equipment in the world, participated in over 900 major energy storage projects in the world, and all projects have stable operation with zero safety accidents.
