Why do I need inverter warranty extension?

  • Experience shows that inverters have to be repaired or replaced at least once in a 20-year lifetime of a PV system
  • Factory warranty usually covers only the first 5 years after commissioning
  • Financing through reserves is expensive and rarely covers the settlement in the event of damage or loss
  • Guaranteed delivery of the same or an adequate replacement device – also for the models no longer available on the market

Decision-making criteria for choosing a suitable warranty extension

  • Duration and terms of notice of your own wish
  • Optional all-inclusive on-site service or remuneration for using your own service technician
  • Minimal losses and waiting periods
  • One-off payment or annual payments
