With the growing focus on achieving the dual-carbon target, photovoltaic technology is rapidly expanding into diverse application scenarios. For over a decade, NEP has been at the forefront of the solar industry, offering cutting-edge technology, dependable quality, and highly efficient systems to deliver customized solutions to customers worldwide.
Among the many remarkable NEP projects, one stands out - a groundbreaking installation situated on a serene lake in Fukuoka, Japan. This visionary project boasts a remarkable installed capacity of 300KW, powered by an array of 1,200 BDM-300 micro-inverters. The BDM-300 is an ingenious AC Module with an ultra-thin design, boasting a mere 25mm thickness, making it the world's thinnest micro inverter.
Due to the particularity of the project site, floating supports are used and the components are installed on the supports. The BDM-300 micro inverter is mounted one-on-one with the components behind the backplane. 15-16 micro-inverters are connected in parallel to one road, a total of 76 channels, respectively, are connected to 6 distribution boards (bus boxes), and are connected to three phases in groups, 220V boost to 6600V, and finally connected to the grid.
The project stands as Japan's first water-based micro inverter installation and is the country's maiden high-voltage 6600V micro inverter project. Leveraging the micro inverter's inherent advantages of "efficiency, safety, and IP67 waterproofing," it offers unparalleled flexibility in installation. The micro-inverters continuously monitor the performance data of each component, providing unique advantages for streamlined plant maintenance.
This landmark project has garnered significant attention from the Japanese government, serving as a guiding reference for promoting photovoltaic power generation in water, mountain, and farmland regions across Japan. The grand ribbon-cutting ceremony and extensive media coverage have further highlighted the significance of this pioneering endeavor.
Microinverters demonstrate their unrivaled advantages in specialized environments such as water bodies, seas, mountains, and extreme temperature zones. With an IP67 waterproof rating and complete internal encapsulation, they effectively shield against salt spray and boast impressive temperature resistance (-40°C to 65°C). These exceptional features make micro-inverters a safe, efficient, and flexible component-level power electronic conversion solution, highly sought after for a diverse range of projects.
As photovoltaic technology continues to advance, NEP remains committed to innovation and elevating the global solar industry to new heights, empowering customers with cutting-edge solutions tailored to meet their unique energy needs.
