Sungrow signs 900 MW agreement 

Global inverter supplier for renewables Sungrow has announced that its 10-year-old inverters have passed the latest stringent testing requirements of stable operation under the weak grid condition, making it the first and only company that meets this rigorous evaluation in China solely by upgrading software, without replacing with new inverters.

Stringent regulations have been newly formulated by China’s Power Dispatch Control Centre in Qinghai Province and the China Electric Power Research Institute, in order to ensure reliable power operation and transmission through a ±800 kV UHVDC line from Qinghai to Henan. This power line is the world’s first ultra-high-voltage power transmission channel for clean energy.

Under these regulations, all PV plants in Qinghai are required to perform stably even when short circuit ratio falls to 1.5.  Inverters must have the ability of high voltage, low voltage and continuous voltage riding through under AC or DC fault of the grid.

Sungrow inverters, which have been stably running for over 10 years, have successfully passed all the tests and can meet the latest grid connect standards thanks to upgraded software, demonstrating the company’s advanced technology. Other brand inverters may need to be replaced entirely, in circumstances where the company might have withdrawn from the inverter sector or the inverters can’t be upgraded because of technical issues. Upgraded software is a more efficient approach to the technical transformation of old PV plants to save cost and improve power generation, as opposed to replacing components or entire inverters.

With increasing amounts of new energy generation all over the world, Sungrow has for many years been a pioneer within the industry with regard to switching PV plants from adapting to power grids to supporting them. The company currently employs the industry’s largest R&D team and has a proven 23-year track record, enabling the company to continue providing high-quality and cutting-edge products to customers and devoting all its operations to the provision of more stable, cost-saving clean power.

In other news, Sungrow has also announced its partnership with Shanghai Electric to supply its latest 1500V 6.25 MW turnkey solution to the 900 MW fifth phase of the Mohammed bin Rashid Al Maktoum Solar Park in Dubai. The agreement further highlights Sungrow’s support for the Dubai Clean Energy Strategy 2050 and its efforts in helping to lower the MENA region’s carbon footprint.

The 900 MW fifth phase of the park is expected to be online in Q2 2021 and will power 270,000 homes, offsetting 1.18 million tons of carbon emissions annually. Based on the Independent Power Producer (IPP) model, ACWA Power in partnership with Gulf Investment Corporation (GIC) won the bid with a tariff of USD 1.6953 cents/kWh, establishing a new global benchmark for solar energy.

The low off-taking price requires a minimised LCOE, which poses tremendous challenges to inverter solutions. Sungrow’s upgraded 1500V turnkey solution to be installed is an ideal match for this landmark project.

The project is a vital part of the strategic agreement forged recently between Shanghai Electric and Sungrow.

“The solution offered by Sungrow fits our demand very well” said Mr Cao Min, President of Shanghai Electric. “The high-efficiency and cost-saving solution, proven delivery capability and prompt service have made them a preferred partner for our growing list of assets. ACWA Power, as the lead developer of the project, has utilised Sungrow inverters in its recent projects including a 500 MW Ibri II project in Oman.

James Wu, Vice President of Sungrow, added that the project will pave the way for more opportunities and facilitate the local decarbonisation at large.

With its local branch established in Dubai, Sungrow is continuing to make big moves with inverters installed in landmark plants. The latest 1H financial report shows a 55.57 percent year-on-year growth in revenue while the cumulative installations reaching 120 GW as of June 2020, indicating the Company’s robust momentum.

Sungrow is the world's most bankable inverter brand with over 120 GW installed worldwide as of June 2020. Founded in 1997 by University Professor Cao Renxian, the company is a leader in the research and development of solar inverters, with the largest dedicated R&D team in the industry and a broad product portfolio offering PV inverter solutions and energy storage systems for utility-scale, commercial, and residential applications, as well as internationally recognised floating PV plant solutions.
