Extension of warranty PLENTICORE BI

Have you already activated the "KOSTAL Smart Warranty"? Before purchasing a warranty extension, registration is mandatory to obtain the full warranty of your inverter. More information here.

Within the first two years of purchase, you can extend the warranty on your inverter by a further 5, 10 or 15 years.

The statutory warranty is not affected by this warranty service.

Furthermore, we will also reimburse an exchange fixed sum to specialist companies (you will find the current fee in the download area at Service https://www.kostal-solar-electric.com/en-gb/Download).

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. If the plausibility check is unsuccessful, you have the option of applying for a warranty extension in a separate form.
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.
