  1. SolaX Power Responsibility

Upon receipt of the required information listed in Section 3, and after attempts to correct the problem with the customer’s assistance, SolaX Power will assign a unique case number to the customer. This number shall be used in reference for all communications regarding the exchange. SolaX Power will dispatch a replacement inverter within 3 working days to the specified customer or installer location. Following the receipt of the replacement inverter, the customer must return the allegedly faulty Inverter in the same packaging material as the replacement inverter. SolaX Power will supply all labels, documentation and freight details for the return of the allegedly faulty inverter. All allegedly faulty inverters must be returned within 10 (ten) working days of the receipt of the replacement inverter.  A qualified installer must be available for the inverter exchange and re-commissioning. The replacement inverter will be covered by the original warranty terms of the faulty inverter for the remaining warranty period of the original (faulty) inverter.


  1. Distributor Responsibility 

In the event of an equipment failure or fault, it is the distributor’s responsibility to work directly with the SolaX Power UK Service Center in order to limit the return of non-faulty equipment. The SolaX Power UK Service Center will work with the distributor to rectify the fault or fault message through telephone support or with direct PC links. Note: In order to qualify for further compensation and a replacement unit, the distributor/installer must first contact the SolaX Power UK Service Center and fulfill the distributor/installer’s responsibilities under Section 3 of this document.


  1. Compensation for Distributors

If faulty equipment is exchanged by a distributor/installer within the warranty period, SolaX Power will make a onetime payment to the distributor of £65.00 as compensation (payable for each site). In the course of inspection by SolaX Power, if the allegedly faulty inverter is found by SolaX Power to be ineligible for exchange under this policy, the compensation payment will not be made and the distributor will be charged for the repair of the unit as noted in clause 7 below. In order to receive the compensation payment, the distributor must provide proof of a valid warranty for the inverter, a correctly issued and fully completed invoice (as provided by SolaX Power with the replacement inverter), and a valid case number for the inverter (as provided by the SolaX Power UK Service Center). The distributor must ensure the return of the suspect equipment prior to reimbursement from SolaX Power. In all instances, the installer or distributor must send these items to: SolaX Power UK Ltd., Unit 10 East Boro Fields, Hemdale Business Park, Nuneaton, CV11 6GL.


  1. Inspection Charge for Inverters Not Found Defective 

If an allegedly faulty Inverter is returned to SolaX Power pursuant to this Policy, and is found by SolaX Power to be free of defects that would qualify it for replacement under this policy, or due to limited liability as stated in clause 2, SolaX Power will charge a flat-rate inspection charge for each Inverter of £65.00, plus shipping and packaging costs.

  6. f. SolaX Power will facilitate Section 6 of this document and pay the rebate to the distributor. It is the distributor’s responsibility to pass this rebate on to the correct Installer. Installer details will be supplied by SolaX Power.


  1. Warranty Extension

The SolaX inverter range is eligible for a warranty extension of 120 months (taking the maximum warranty period to 20 years from the point of commissioning).  The warranty extension is available for purchase up to 36 months from the commissioning date of the inverter.


  1. Warranty Registration

It is a requirement that all inverters are registered in order that they qualify under the terms of the Exchange Program.  It is a requirement that all suppliers/installers provide the private end-user with a the relevant warranty registration certificate, and it is a requirement that the end-user (or the installer on behalf of their customer) register the warranty at the relevant address on the Solax website (as specified on the registration certificate), at which point a full warranty certificate is issued.  Warranties must be registered no more than six weeks following the date of commissioning.  The information required at the point of registration is as follows:


  1. Inverter model
  2. Inverter serial number
  • Installation date
  1. Customer name
  2. Installation post code
  3. Full installation address
  • Name of installation company


In the case of extended warranties, in addition to the information required above, it is also necessary to enter a unique identifier found on the extended warranty registration certificate.  Without this reference number it will only be possible to register the inverter for the standard 120 month warranty period.


Upon receipt of the registration request, SolaX will issue a full warranty certificate to the customer by email within seven working days.
