SOFARSOLAR Warranty Terms and Conditions


The standard warranty period for SOFARSOLAR inverters is 60 months (5 years) from the date of purchase. Our end customer needs to provide the valid purchasing invoice to verify the date of purchase.

If our end customer fails to provide the valid purchasing invoice, the standard warranty period for SOFARSOLAR inverters is 63 months (5.25 years) from the date of production (it’s on the SN) from Shenzhen SOFARSOLAR Co., Ltd.

Our end customer can also purchase an extension of this SOFARSOLAR standard warranty during 12 months from the date of manufacturing. Refer to the SOFARSOLAR price list for further information.


In the case of a faulty inverter during the agreed SOFARSOLAR warranty period, please report defective inverters with a brief error description to our service hotline for registering and send your warranty card to our service department by fax/email to process the warranty claim. You may also contact your dealer (SOFARSOLAR authorized dealer or distributor) or installer if your unit is defective or faulty.

To make a claim under the warranty periods of SOFARSOLAR, you need to provide us the following information and documentation of the faulty inverter:

  • Product Model (e.g. SOFAR 20000TL) and product serial number (e.g. SC1ES520E99001).

  • A copy of the valid purchasing invoice and warranty card of the inverter.

  • Error messages on the LCD screen (if available) and additional information about the fault/error.

  • Detailed information about the entire system (module, PV system diagram, etc.).

  • Documentation of previous claims/exchanges (if applicable).

If an inverter is faulty while it is under SOFARSOLAR warranty period, it will be:

  • Repaired by SOFARSOLAR

  • Repaired on-site

  • Exchanged with a refurbished inverter that includes all firmware updates

If the inverter needs to be exchanged, the remainder of the warranty period will be transferred to the replacement unit, i.e. the warranty period of the original device will continue. In this event, you will not receive a new warranty card, and this replacement will be registered by SOFARSOLAR. If the remaining warranty period is less than 6 months, you will automatically receive a 6-month warranty period for the replacement unit.

The warranty includes the cost of work and material necessary to regain faultless functioning inverters. All other costs, particularly transports, travel- and accommodation cost of SOFARSOLAR personnel as well as costs of your own staff are not included in the warranty. Furthermore, claims for compensation for direct or indirect damages arising from the defective inverter are not covered by the warranty.

Faulty inverters and components should be returned to SOFARSOLAR, they must be packed in their original or equivalent packaging for transportation.

SOFARSOLAR keeps the right to arrange the warranty service for end users and to use third parties for performing warranty services.

All warranty services are free of charge only if the action is agreed with SOFARSOLAR in advance.
