Hopewind’s 385K string inverter is recognized as the world’s most powerful string inverter after a throughout market research conducted by Solarbe Global, a well-known PV industry media.

The dominance of utility-scale PV in global PV installations is indisputable, as it emerges as a key catalyst in achieving the net-zero target by 2030. Projections by BNEF reveal a remarkable growth trajectory, with utility-scale PV installations poised to soar from 920 GW in 2023 to an astounding 2,707 GW by 2030. Concurrently, a silent revolution is unfolding in the utility-scale solar sector, with string inverters gradually supplanting central inverters. Research Nester's survey predicts that by 2036, string inverters will command a substantial 54% share of the global utility-scale inverter market. This shift is attributed to their compact size, reduced weight, on-site spare replacement capability, and minimized production losses in the event of inverter failure.

As global PV inverter manufacturers intensify their pursuit of higher power inverters, the competition has grown fierce. Hopewind’s groundbreaking achievement comes in the form of the 385K string inverter, ranked as the world's most powerful utility-scale string inverter by Solarbe Global. This prestigious accolade was awarded following a comprehensive survey that evaluated 13 branded utility-scale string inverters from leading manufacturers. Boasting maximum output power of 385kW, Hopewind’s 385K string inverter is purpose-built for large utility-scale and high-voltage industrial and commercial PV projects.

It showcases a host of exceptional features that outpace other branded inverters.

Higher power for higher system yields and lower LCOE  

Set with the highest output power in the industry, Hopewind’s 385K inverter has an impressive max efficiency rating of 99.01%. Characterizing 8*65A multiple MPPTs and the max MPPT input current of 65A, it is perfectly compatible with both 182mm and 210mm high power modules. By installing high power modules and higher power inverters, less PV modules and inverters will be needed in a big-scaled project, thus reducing the land use and ensuring lower LCOE and higher yields for end users.

On the other, the 385K inverter can still achieve full load output at up to 40 degrees without derating, ensuring higher yields for the plants located in high ambient temperatures, which is more commonly seen in utility-scale solar power plants.

I-V curve diagnosis for quick system fault locations

Finding faulty PV modules in a large ground-mounted solar plant can be very time-consuming and difficult without efficient tools. To address this issue, this inverter offers I-V curve diagnosis feature, which carry out online I-V curve analysis on entire strings with advanced diagnosis algorithm. The scanning would help to find out and identify the strings with low performance or faults, which would help to achieve proactive maintenance, higher O&M efficiency and lower operation cost.

Adapt to unstable power grid and harsh environments

Customers often express concerns about projects located in mountainous or remote areas with poor-quality power grids, where the power supply might be unstable and prone to fluctuations. Additionally, projects situated in harsh environments, such as hot, rainy, dusty, highly corrosive, and humid areas, present challenges to inverter durability. Addressing these concerns, Hopewind inverters outperform other brands with an impressive SCR value of 1.03, ensuring better adaptability to changes and instabilities in the power grid, even in mountainous and remote areas. It also supports grid-forming, allowing itself to autonomously establish and maintain voltage and frequency control, providing stable and reliable power supply.

The 385K inverter is specifically designed to thrive in challenging environments. It operates efficiently within a temperature range of -25°C to 60°C. Furthermore, the inverter boasts an IP66 protection rating, ensuring high dust-proof and water-proof performance. This quality is particularly beneficial for projects in dusty environments or areas with heavy rainfall and water bodies, effectively reducing the risk of short circuits and overheating damage. Additionally, its is also built with C5 anti-corrosion degree, making it highly secure for corrosive environments like seaside areas, islands, or locations near oil fields and chemical plants.
