It is possible to extend the inverter’s existing warranty by 5 years within the first two years after purchase. The prices given below always relate to the lowest power class of the inverter. The individual price is updated within the selected product as soon as all mandatory fields have been completed.
* 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.
