Covers manufacturing defects and faults not attributable to installation, with authorized SolaX technical support. Ideal for C&I systems that require long-term protection on a 120 kW investment.
The SolaX X3-FTH-120K-10years warranty extension allows you to extend the coverage of your 120 kW three-phase string inverter up to a total of 10 years, protecting your investment in commercial and industrial (C&I) photovoltaic systems. The X3-FTH-120K inverter (X3 FORTH series) is designed for large-scale applications with maximum efficiency up to 99%, 12 MPPT, IP66 protection, and optional AFCI.
Why choose the warranty extension for the X3-FTH-120K inverter?
A 120 kW inverter is the heart of a photovoltaic system of over 150 kWp. A failure outside of warranty can result in high repair 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 failures not attributable to external causes. Damage from weather events such as lightning or grid overvoltage is excluded and must be covered by a specific All Risk insurance policy for photovoltaic systems.
Can I purchase the warranty extension after the X3-FTH-120K inverter has already been installed?
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 a defective component?
Yes. In the event of a warranty-covered failure, SolaX will repair or replace the inverter or 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-120K warranty extension compatible with GSE incentives or Conto Energia?
Yes. The warranty extension is a commercial service that does not interfere with GSE incentive procedures. For systems accessing incentive schemes, having a ten-year warranty on the main inverter helps meet the operational continuity requirements required by the responsible parties.
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 supplied 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 technical intervention documentation.
