Sungrow, has announced that China ’s largest PV & energy storage microgrid power plant,with 13 MW of PV inverters, 7 MW of energy storage inverters, and 23.5 MWh of Lithium Ion batteries was successfully connected to the grid in Shuanghu, China, one of the highest regions (over 5000m altitude) in the world located in China’s Tibet province.
The 20 MW microgrid power plant aims to provide electricity to over 14,000 people living in the vicinity, with average elevations reaching heights of over 5000 meters. With the lowest temperatures recorded at -40⁰C and severe winds plaguing the region for over half the year,Shuanghu County’s extreme climate—which many say is like a winter lasting 10 months—has frequently posed challenges to inverters and other solar components operating in the region’s frigid conditions.
Sungrow’s solar and energy storage inverters, together with the company’s storage system solutions, are employed in this project. Sungrow’s inverters are designed with standardized container specifications, drastically shortening the time required for installation and commissioning which in turn reduces overall installed costs. In Shuanghu’s harsh conditions, inverters and energy storage components are designed to ensure stable operation and longevity with appropriate insulation and temperature control settings. Sungrow-Samsung’s battery containers are insulated to protect internal devices even in subzero temperatures; inverters and their components are engineered with cold start capability even at 40 degrees below zero.In difficult geographic locations where installation and service-related costs are proportionately higher, these types of design features are essential.
Backed by class-leading solar inverter hardware, Sungrow’s massive microgrid power plant is also designed for remote monitoring and makes unattended operation a reality. Designed to be easily integrated with local grid, the Shuanghu project will provide over 6.6 million kWh per year to an area where frequent power shortages forced residents to rely on shared, time-of-use regulated grid powered by diesel fuel generators. The unreliability of that grid resulted in many residents relying on traditional Tibetan butter lamps to light their homes. Sungrow’s efforts in bringing clean, renewable electricity to Shuanghu is part of the company’s longstanding efforts to improving the environment, and solving energy shortage crises worldwide.
“We are always dedicated to bringing green and effective energy to markets in need all around the world, especially for those who reside in areas withlimited access to electricity.”said Professor Renxian Cao, President of Sungrow.
