Shenzhen Kstar Science&Technology Co.,Ltd., the global leading smart inverter solution supplier for new energy, announced that the company’s central inverter (GSL2500C and GSL1250C,High efficiency up to 99% ) solutions have been operational stably and safely for more than three years at a 300 MW floating Solar Power Park in Zhejiang,China, which is the largest solar-water park in China. The big project again demonstrates the rapid growth of KSTAR in PV emerging market and it is a significant milestone that KSTAR contributed to in the world.

To save land resources and have less impact on the aquatic environment, the 300MW floating solar power plant has been installed and operated successfully in Zhejiang,China since Jan 2017, where the PV central inverters are all provided by KSTAR. The PV power plant on a body of water has a high power generation efficiency,and brings low operations and maintenance costs as well as a minimal impact on the maritime life.

Covering nearly 300 hectares, the 300MW solar power plant has been completely grid-connected since Jan 2017 with an expected annual generation of 220 million KWH. It is the largest floating water PV plant in China, which all the electricity is connected into the State Grid Corporation of China,greatly reducing the pressure of local power grid operation,making environment much greener by utilizing renewable energy.The power plant can save 70,000 tuns of coal annually, and reduces 189,200 tons of carbon dioxide and 14.32 million tons of sulfur dioxide.

The annual electricity revenue of the owner is about 35 million USD, and the annual fishery income can reach 2 million USD.

The floating power plant is located in the subtropical region with a monsoon climate.The annual average temperature is 16.0℃,and the highest of the average is 28.2 in July,℃, the lowest temperature is 3.8℃.There is sufficient rainfall, with an annual average rainfall of 1272.8mm. The peak month of precipitation is September, accounting for an average of 14% of the annual rainfall. The environment is a challenge for PV manufacturers, but for KSTAR, its flexible turnkey solutions provide higher yields, safety and reliability for the whole project.

KSTAR has provided many central inverters to the 300MW  water-based floating solar Power Plant,which are specifically customized for floating solar power plants and are able to work safely in wet and erosive environments.The turkey solution is high efficiency power generation, high reliability and greater adaptability.

KSTAR greatly shortens construction period and saves operation cost, but also has great advantages in post-operation and maintenance, anti-corrosion capacity, smart anti-PID solutions.There are four big advantages for KSTAR turnkey solution for central inverters:

1.Low cost in Investment and the system maintenance.

The solutions integrate high-efficiency booster transformer,medium-voltage distribution and monitoring system to save system cost.

Integral hoisting reduces the construction difficulty and shortens the construction period. The inverter and transformer is unified maintenance & construction,thus users are no worries.The transformer can be customized, flexible to cope with a variety of application scenarios.

2. Excellent natural cooling design

The heat-dissipating method  is forced air cooling.The duct is a vertical design. The power module employs the way of air extraction.

The  heat dissipation from the air duct of the inverter is designed to be isolated from the air duct of the magnetic unit (reactor).

The fan is intelligent control, which can only be started  when the temperature reaches the limit.

  • Strong corrosion resistance

IP54 meets the application conditions of the floating  power station on the water, and guarantee the protection against corrosion in high humidity and high salt fog environment.

  • Strong protection and maintenance capability

KSTAR’s inverters are featuring PID protection,which can effectively prevent PID attenuation of components and ensure the performance of components and power generation of the station.Customers are no need to worry that the components will be corrosion in wet and high temperature. KSTAR’s turnkey solutions with central inverters installed is flexible and strong adaptability, where the owners don’t need to change the layout of  industrial pools, drinking water reservoirs and small lakes. Moreover, the floating power plant does not affect the civil construction, but help the customer to reduce the investment cost, speed up the project’s completion, and ultimately achieve the maximum revenue for the owners.Besides,that greatly reduce water surface evaporation and save water resources,also creating a better hatching environment for fish and increase aquatic production.

“ It is a pleasure that we supply the intelligent turnkey solutions for the big project. We are encouraged by the fact that the products have received wide attention and recognition from our industry customers, colleagues, and media. More than three years fly, the floating PV power plant is operated successfully,and we do a great job for the customers. We will continue to work hard to meet growing demands of our old and new customers.,” said Gary Ye, the Vice-GM of Shenzhen Kstar Science&Technology Co.,Ltd.
