Sungrow, the global leading inverter solution supplier for renewables confirmed that the company supplied a 93 mega-watt, alternating current (MWac) project with its outdoor central inverter solutions. The project, lately put into commercial operation, is in Yeongam, South Jeolla province, South Korea. It is remarkable as one out of the only two solar projects of an estimated 100 MW capacity in the country, and landmark application as of the largest hybrid energy systems in the region.

Positioned in a 2.96 million square meters’ mountainous site in Daemyeong, Yeongam, about 340 kilometers (km) south of Seoul, the PV project is a part of the South Korean largest hybrid energy system integrating PV, wind and energy storage, presenting agility within a complex landform and high humidity environment.

The PV plant is anticipated to produce 120 Gigawatt-hours (GWh) of clean energy per year, enough to power 30,000 households and equivalent to eliminating carbon dioxide by 56,000 tonnes. Daemyung Energy, the project's developer, will sell renewable energy certificate (REC) to Korea South-East Power for solar power over 20 years, anticipated to raise about 30 billion Korean Won ($24.9 million) per year.

A wide portfolio of Sungrow outdoor central inverter solutions ranging from 1.25 MW to 3 MW was deployed on-site, offering an optimal performance given the advanced three-level topology technology. Equipped with multiple MPPTs, the solutions are ideal for mountainous installations. Armed with a high protection level of IP65 and a built-in PID recovery function, the solutions maintain unprecedented yields for the plant even in high humid conditions. With a smart control unit (SCU) and being compliant with the power plant controller DER-AVM, the solutions enable timely online analysis and troubleshooting.

"The successful intake of the landmark project has enabled Sungrow to accumulate valuable experience and laid a solid foundation in the field of solar energy in South Korea. The challenge posed by the pandemic outbreak won't stop Sungrow from providing the best effort at creating customer value and decarbonizing local economies," said Hoseob Kim, Country Manager of Sungrow South Korea.

Sungrow has over 1 GW of its inverter solutions deployed in South Korea as the leading solar player in both the utility-scale sector and distributed generation segment across the nation. The Company has established a comprehensive local team offering responsive sales, technical support, and after-sale service, ideally meeting local mounting demands - the South Korean MOTIE (Ministry of Trade, Industry, and Energy) updated that installations of renewable energy will be increased from 12.7 GW to 42.7 GW and will account for 20% of the total energy by 2030.
