In September 2018, Sungrow Power Supply Co., Ltd. and Yuexin reached a cooperation to purchase a customized IPX56 water spray test device (including shower test device). Previously, Sungrow had found several companies and built its own waterproof laboratory, but the equipment was not very easy to use and prone to failure. After contacting Yuexin, Li Gong and his team of 4 people from the R&D Department came to Guangzhou to conduct an investigation visit to Yuexin.

Since Yuexin is a professional manufacturer of waterproof testing equipment, Li Gong has great confidence in both the production process and the use of exhibition hall equipment. A few days later, our engineers were also invited to give guidance on the renovation of their existing waterproof test room. At present, the IPX56 flushing test room has been put into use in the waterproof test room of Sungrow.
