The warranty extension can be completed by the end customer. To extend the warranty, it is necessary to have the invoice available and register on the company website: https://guarantee.solar-inverter.com. In case the end customer does not register, a standard warranty of 5 years is applicable.
Delta offers an extended warranty due to the high product quality and strengthens the confidence in SOLIVIA solar inverters. “A PV installation is a valuable investment, many feed-in tariffs are guaranteed for up to 20 years”, states Andreas Schmidt, Head of Marketing, “Our SOLIVIA solar inverters are functionally reliable and able to operate for more than 20 years”.
