Waterproofing Laboratory

Sungrow Power Supply -IP Waterproofing Laboratory

In September 2018, Sungrow Power Supply Co., Ltd. partnered with Yuexin to purchase a custom‑made IPX56 water‑spray test rig, including a shower‑head testing unit. Prior to this, Sungrow had approached several companies and even established its own waterproof‑testing laboratory; however, the equipment proved unreliable and prone to malfunctions. Following contact with Yuexin, Li, a member of the R&D team, along with three colleagues, traveled to Guangzhou to conduct an on‑site inspection and visit.

As Yuexin is a specialized manufacturer of waterproof testing equipment, both its production processes and the operation of its showroom‑equipped systems have instilled Engineer Li with great confidence. A few days later, our engineers were also invited to visit and provide guidance on upgrading their existing waterproof testing laboratory. At present, The IPX56 water‑jet test chamber has already been put into operation at Sungrow’s waterproof testing laboratory.
