It is possible to extend the inverter’s five-year warranty by a further 5, 10 or 15 years within the first two years of purchase.
Our services covered by the warranty include a rapid exchange service to ensure that your PV system is quickly back in operation. We will organize the collection of your defective device and we will also cover the freight costs incurred for this.
Furthermore, we will also reimburse an exchange fixed sum to specialist companies (you will find the current fee in the download area at Service)

Please note:
Please specify the serial number of your inverter. This will be checked for plausibility. Should your inverter have been replaced at any time, the warranty completion date will be transferred to the serial number of the replacement.
The warranty begins on the day that the end customer purchased the inverter. Please confirm the date of purchase when purchasing a warranty extension in this web shop.
The sales receipt must be presented to KOSTAL as proof of purchase upon request. Should this not be available to you in the event of a claim, or if the date of purchase specified by you is incorrect, we will have to reject the warranty extension retrospectively.
