Sungrow raises inverter, storage prices by up to 15%

Chinese inverter and energy storage supplier Sungrow has announced price increases of 5% to 15% across a range of solar and storage products. The move marks its second price adjustment this year.

The new prices will take effect on Sept. 20. Orders signed and formally placed before that date will remain subject to existing contract terms, while orders placed from Sept. 20 will follow the revised pricing structure.

Sungrow will raise prices for string, modular and matrix inverters by 5% to 10%, while prices for medium-voltage grid-connected inverters will increase by 10% to 15%.

Prices for energy storage power conversion systems (PCS) will rise by 5% to 10%, with integrated PCS units increasing by 10% to 15%. The company will also raise prices for its PT utility-scale storage systems and PS commercial and industrial storage systems by 5% to 10%.

Sungrow said in a customer notice that upstream material costs had risen more than expected, despite efforts to secure long-term supplies, optimize procurement and reduce internal expenses. A manager in the company’s energy storage business separately told Chinese media that higher copper and aluminum prices were the main drivers of the adjustment. The manager added that the increase was also intended to curb destructive low-price competition.

Cost pressures are evident across several key inputs. Data from the China Nonferrous Metals Industry Association (CNMIA) show that average domestic copper and aluminum prices rose by 31.4% and 18.8%, respectively, in the first half of 2026. Silver prices increased even more sharply, while power electronics suppliers have reported higher costs and tighter availability for components such as printed circuit boards, insulated-gate bipolar transistors and memory chips. Industry participants have partly attributed the shortages to rising demand from artificial intelligence data centers and other computing infrastructure.

Sungrow, Ginlong Technologies, Sineng and several other inverter manufacturers raised prices for storage products by about 6% to 10% in the first quarter.

Price increases have since spread across the storage supply chain. Sinexcel raised prices for products including storage microgrids and residential storage systems by 10% to 30% from July 21. Inovance increased prices for storage converters and integrated storage systems by 5% to 15% from Aug. 30.

The China Energy Storage Alliance said more than 10 storage-related suppliers had announced price increases since July, ranging from 2% to 30%.

Battery costs are also facing additional policy pressure. China introduced a 2% consumption tax on lithium-ion batteries on Sept. 1, 2026. The rate is scheduled to rise to 4% on Sept. 1, 2027.

The latest increases indicate that manufacturers are increasingly passing higher upstream costs on to inverter, PCS and storage-system customers after several years of intense price competition. However, announced list-price increases may not be fully reflected in transaction prices, particularly in large-scale tenders. Whether the increases persist will depend on raw material prices, component availability and competitive bidding conditions in the coming quarters.
