Sungrow will lift list prices on solar inverters and energy storage products by between 5% and 15% from Sept. 20, blaming higher costs for raw materials and components, pv magazine reported. It is the second time the company has repriced its lineup this year.
The steepest increases hit medium-voltage grid-connected inverters, which go up 10% to 15%, while string, modular and matrix inverters move up in a 5% to 10% band, according to pv magazine.
A manager in Sungrow's storage business separately told Chinese media that copper and aluminum inputs were behind the decision, pv magazine reported. Figures from the China Nonferrous Metals Industry Association, cited by pv magazine, put the average domestic copper price 31.4% higher and aluminum 18.8% higher across the first half of 2026.
The cost pressure comes alongside a new tax line for battery makers. A 2% consumption tax on lithium-ion batteries took effect in China on Sept. 1, 2026, and is set to double to 4% on Sept. 1, 2027, pv magazine reported.
Other suppliers have taken the same route. The China Energy Storage Alliance counted more than 10 storage-related vendors that had lifted prices since July, with the increases spread across a 2% to 30% range, according to pv magazine.
