Quality and Warranty

During the production and assembly of the next3, each unit undergoes several checks and tests which strictly comply with established procedures and device safety requirements. The manufacturing, assembling, and testing of each next3 are entirely carried out in our factory in Sion (CH). The warranty for this equipment depends upon the strict application of the instructions in this manual.  

The next3 inverter has a ten (10) years warranty (starting from the date of purchase) against material and manufacturing defaults. The defective product will be either repaired or replaced at the discretion of Studer Innotec. A warranty extension up to 15 years is possible with the Studer Care program, giving also other advantages.  

Exclusion of warranty  

No warranty claims will be accepted for damages resulting from handling, use or treatment that are not explicitly mentioned in this manual. Damages arising from the following causes are excluded from the warranty: 

  • Voltage higher than 900V across PV terminals.  
  • Voltage higher than 70V across battery terminals.  
  • Accidental presence of liquids in the equipment or oxidation due to condensation.  
  • Damage resulting from falls or mechanical shocks.  
  • Modifications carried out without the explicit authorisation of Studer Innotec.  
  • Nuts or screws that have been too much or not enough tightened during the 
    installation or maintenance.  
  • Damage due to atmospheric surge voltage (lightning).  
  • Damage due to inappropriate transportation or packaging.  
  • Damages due to improper installation  
  • Disappearance of original identification marks. 

Never take off or damage the rating plate showing the serial number. It enables to check and follow-up the data specific to each equipment and is vital for any warranty claim.
