The SolaX X3-FTH-125K-10year warranty extension allows you to extend the coverage of your 125 kW three-phase string inverter up to a total of 10 years, protecting your investment in commercial and industrial (C&I) photovoltaic systems.

Why choose the warranty extension for the X3-FTH-125K inverter?
A 125 kW inverter is the heart of a photovoltaic system of over 180 kWp. A failure outside of warranty can result in high replacement costs and production downtime, directly impacting the economic return of the system. With the 10-year extended warranty, both the installer and the end customer are assured of complete coverage for the entire typical payback period of C&I systems, guaranteed by the authorized SolaX service network.

Frequently Asked Questions
Does the warranty extension also cover lightning or overvoltage damage?
The SolaX extended warranty covers manufacturing defects and internal inverter faults not attributable to external causes. Damage from atmospheric events such as lightning or grid overvoltages is excluded and must be covered by a specific All Risk insurance policy for photovoltaic systems.
Can I purchase the warranty extension after I have already installed the X3-FTH-125K inverter?
Yes, the warranty extension can also be purchased after the inverter has been bought, within the terms set by SolaX (generally within 36 months from commissioning). It is important to keep the original purchase documentation and the inverter serial number to register on the SolaX portal.
Is the extended warranty valid in case of replacement of the defective component?
Yes. In the event of a warranty-covered fault, SolaX will repair or replace the inverter or the defective component through its authorized service network. Labor and spare parts costs are included in the coverage according to the terms of the SolaX warranty sheet.
Is the X3-FTH-125K warranty extension compatible with GSE incentives or PNRR tenders?
Yes. The warranty extension is a commercial service that does not interfere with GSE incentive procedures. For public tenders or PNRR projects, having a ten-year warranty on the main inverter often meets the requirements for operational continuity and technical reliability specified in the tenders.
What happens if the inverter is replaced during the extended warranty period?
If the inverter is fully replaced under warranty, the remaining coverage is transferred to the replacement unit provided by SolaX for the remaining duration of the original contract. It is essential to register the new serial number on the SolaX portal and keep all documentation of the technical intervention.
