Growatt will implement a price increase of 5% to 10% on string inverters and energy storage systems effective October 8, 2026. This adjustment follows a period of rising raw material costs and tightening supply for core components.
Why it matters
Operators in the energy storage sector face margin compression as manufacturers pass on increased costs for raw materials and components. This move reflects a broader trend of price volatility that has seen over ten major enterprises adjust their pricing since July 2026.
Growatt is raising prices by 5% to 10% for inverters and storage systems, joining at least ten other energy storage firms that have revised pricing since July 2026. While other industry players have implemented hikes ranging from 2% to 30%, the specific long-term market impact remains unclear.
The players
Growatt
A global manufacturer and distributor of string inverters and energy storage systems for residential and commercial applications.
The details
Growatt informed dealer partners of the upcoming price shift via a formal notice issued September 21, 2026. The company intends to mitigate the immediate impact on existing projects by honoring original pricing for orders where contracts and payments are finalized before the October 8 implementation date. This mechanism forces operators to reconcile current project backlogs against the deadline to lock in legacy costs.
Timeline
July 2026: More than ten energy storage enterprises began releasing price revision notices.
September 21, 2026: Growatt issued its formal price adjustment notice to dealers.
October 8, 2026: The 5% to 10% price increases become effective for affected systems.
Market Landscape
Growatt's move follows a documented trend of price revisions across at least ten energy storage enterprises since July 2026. This industry-wide shift mirrors broader volatility in the raw material and component markets that has characterized the sector throughout the year.
Owners and managers should verify whether their current procurement contracts qualify for the October 8 price grace period. Review project margins immediately to determine if the 5% to 10% cost increase requires adjustments to client bids or supplier selection.
The takeaway
Rising raw material costs are forcing manufacturers to adjust price lists, shifting the burden of supply chain inflation onto installers and dealers. Operators should prioritize audit-ready records of all payment dates to capitalize on legacy pricing before upcoming adjustment deadlines.
What happens next
Operators should ensure all contracts and payments for planned inverter and storage system orders are fully executed and cleared before the October 8, 2026, deadline to avoid the announced 5% to 10% price increase.
