Growatt has issued a notice that prices for its string inverters and energy storage systems will rise by 5% to 10% effective October 8, 2026. This adjustment follows a period of rising raw material costs and tightening supply for core components.
Why it matters
Households planning to invest in residential energy hardware will face higher upfront costs as manufacturers adjust to volatile supply chains. This shift reflects a broader industry trend where over ten enterprises have raised prices since July 2026 to offset production pressures.
Growatt is implementing a 5% to 10% price increase on inverters and storage systems starting October 8. This mirrors a wider market trend where competitors have reported price hikes ranging from 2% to 30% since July 2026.
The players
Growatt
A manufacturer of string inverters and energy storage systems that sells products to homeowners via dealer networks.
The details
The price increase propagates to the household level when dealers pass along the higher manufacturing costs for string inverters and storage units. Growatt stated that this policy is a response to rising costs for raw materials and constrained supply for essential components. Consumers with signed contracts and completed payments processed before October 8 will be protected from these new price levels.
Timeline
July 2026 marked the period when energy storage enterprises began releasing price revision notices.
Growatt issued its official price adjustment notice to dealers on September 21, 2026.
The new pricing structure becomes effective for all applicable products on October 8, 2026.
Money Landscape
This move marks a continuation of the industry-wide price adjustment trend that began among energy storage enterprises in July 2026. It reflects a shift in the supply chain for renewable hardware as manufacturers attempt to stabilize margins against rising raw material costs.
If you are in the market for a residential energy storage system, verify your contract status to ensure your purchase qualifies for pre-hike pricing. Households currently planning these installations should speak with a professional to understand how these price fluctuations affect their total project budget.
The takeaway
Rising raw material costs are increasingly being passed to the consumer in the energy storage market. Before finalizing any equipment purchases, review your signed contract dates to determine if you are eligible for legacy pricing ahead of the October 8 implementation.
What happens next
Consumers with pending installation projects should confirm with their contractors if their specific purchase orders will be finalized before the October 8, 2026, deadline.
