Excellent technical support for continuous operation of your photovoltaics


At Fronius we are not only committed to providing first-class products, but also the highest level of customer service. Back in 2000, when photovoltaics was still in its infancy, Fronius developed a program that today is still the most innovative and successful in the marketplace, with the fastest response time. 

"The programme’s secret lies in the special service-friendly design of our devices, which enables every device to be repaired easily, efficiently and onsite, at its installation location. The entire device does not need to be replaced, only the affected components. We call this the Fronius PC board replacement process. Thanks to the intelligent mounting system of our Fronius inverters, replacing a device is quick and cost-effective.  FOr example for our SnapINverters the electrical connection area does not need to be removed; the device is simply swivelled out and a replacement device swivelled into position. This eliminates the need for cabling work, reducing the labour time and costs on the service. Our Fronius System Partners can repair the Fronius inverter onsite and therefore keep the downtime of the photovoltaic system to a minimum. This gives us an essential advantage over other manufacturers, for whom installers must often wait a long time for the required spare parts or the correct replacement device."



Strong brands stand out thanks to their excellent customer service. As a family-run business, customer satisfaction is close to our hearts.The Fronius Solar.web online platform and its integrated monitoring functions enable installers to keep a close eye on the PV system and take preventive action. This helps them to detect and rectify potential issues before they manifest as fully fledged malfunctions.

To ensure installers can always provide the best possible level of customer service, they receive extensive telephone support from qualified Fronius technicians. With the Fronius Solar Online Support (SOS) tool, your installer has all the key information about your Fronius product at their fingertips, accessible round the clock on their laptop, tablet or smartphone – even at the weekend. Thanks to the unique Fronius service plan, if a Fronius device needs to be repaired, one visit to the site by trained installers is all it takes to get the PV system back up and running again as quickly as possible.

Fronius System Partners are installation companies that receive comprehensive training from Fronius. They are qualified to integrate our products and solutions into the overall system landscape of your solar energy supply, install and commission them correctly, and provide proactive customer support.
