Extension of warranty PLENTICORE plus

Have you already activated the "KOSTAL Smart Warranty"? It is absolutely essential that you activate this before purchasing a warranty extension in order to obtain the full warranty for your inverter. More information here.

It is possible to extend the inverter’s existing warranty by 5 years within the first two years after purchase. If initial commissioning is carried out on or after 1. April 2022, the KOSTAL Smart Warranty plus applies to all inverters up to 20 kW, so it is not possible to purchase a chargeable 5-year warranty extension. 

The statutory warranty is not affected by this warranty service.

Our services offered under the warranty include a rapid exchange service to ensure that your PV system is back up and running in no time. We will organize the collection of your defective device and we will also cover the freight costs incurred for this. Furthermore, we reimburse an exchange fixed sum for specialist companies. You can find our service and warranty conditions, including the applicable exchange fixed sums, in the download area on our homepage.

Note:
Please state 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 inverter’s commissioning date. You confirm this commissioning date with us by activating the warranty (Smart Warranty) in this online shop. At the request of KOSTAL, the proof of purchase or the commissioning report must be submitted as evidence. Should this not be available to you in the event of a claim, or if the date of commissioning specified by you is incorrect, we will have to reject the warranty extension retrospectively.
