Gigawatt-Scale Offshore Solar Farm Connects to the Grid, Powered byHuawei Inverters
A groundbreaking achievement in renewable energy: The world’s largest open-sea photovoltaic (PV) project, a 1-gigawatt (GW) facility in Shandong, China, has successfully connected to thenational grid, marking a significant leap forward in harnessing solar power from offshore environments. This milestone is further amplified by the project’s reliance on over3,000 Huawei SUN2000-300KTL inverters, showcasing the growing role of advanced technology in large-scale renewable energy deployments.
The HG14 project, operated by the National Energy GroupGuohua Investment Shandong Branch, achieved its initial grid connection on November 13th, 2024, as reported by IT Home and Huawei’s Smart PV official account. Spanning approximately 1,223 hectares of the East China Sea off the coast of Dongying City, the project received government approval in July 2024. The massive scale of the project is evident in its 157 individual generating units, each equipped with dozens of Huawei’s high-capacity inverters.
These SUN2000-300KTL inverters play a crucial role in converting the direct current (DC) electricity generated by the solar panels into alternating current (AC) electricity. The AC power is then stepped up to 66 kV before being fed into a nearby 220 kV photovoltaic substationon land, ensuring efficient and stable power transmission. Huawei highlights that its inverters offer a demonstrably higher energy conversion efficiency, exceeding comparable products by over 1%, resulting in increased power generation.
Beyond efficiency, the inverters incorporate innovative features designed to optimize performance and reduce maintenance. The L5-levelMBUS power line carrier communication functionality eliminates the need for extensive conventional communication cabling, significantly reducing both labor costs and material usage. Furthermore, the intelligent fan dust-removal system minimizes downtime by preventing blockages caused by debris like seabird feathers and dust, ensuring continuous operation throughout the inverter’s lifespan.
This projectrepresents a significant advancement in several key areas. Firstly, it showcases the viability of large-scale offshore solar power generation, addressing concerns about land scarcity and maximizing solar energy harvesting potential. Secondly, it underscores the increasing importance of advanced inverter technology in optimizing the performance and reliability of such projects. The Huawei inverters’efficiency gains and intelligent features contribute significantly to the overall economic viability and environmental impact of the HG14 project.
The successful grid connection of the HG14 project paves the way for future large-scale offshore solar farms, contributing substantially to China’s and the world’s renewable energy goals. Further researchand development in areas such as improved inverter technology, optimized array designs, and efficient grid integration strategies will be crucial for expanding the global capacity of offshore solar power.
