Smart solar technology from the solar power experts

5/2/2024 / Sinsheim, Germany
When the Rappoldt family from southern Germany decided to install their own PV system, they chose installation firm Febesol, an experienced Fronius System Partner (FSP). Febesol installed the 20 kWp system, the heart of which is the two Fronius GEN24 Plus 10.0 hybrid inverters, thereby fulfilling the Rappoldt family's dream of self-sufficient energy production. The FSP combined the PV system with a BYD Battery-Box Premium HVS 10.2 and the Fronius Wattpilot Home 11 kW charging solution.
As a reliable partner, Fronius offers all components from a single source, enabling installers to make 24 hours of sun a reality for their customers. What does 24 hours of sun mean? It’s a world in which electricity, heating, cooling, and mobility are all powered by renewable energy alone. “Fronius is a leading expert in solar technology. The devices are sustainable because they are manufactured in Europe to the highest quality standards,” explains Daniel Fellhauer from Fronius System Partner Febesol, citing “Made in Europe” as one of Fronius' many strengths. Approximately 3.4 million Fronius inverters are currently in operation. This equates to roughly 33 Danube hydroelectric power plants, so we're talking a lot of power here.

A strong Partnership

The advantages of working with Fronius for partners and customers are evident: The former benefit from our first-class know-how and 30 years of experience in the solar market, from premium service and support plus smart technology from a single source. As a reliable partner, Fronius guarantees that the individual products work flawlessly together. This means that the versatile Fronius GEN24 Plus, the BYD batteries and the Fronius Wattpilot are fully compatible with the PV system. Due to this compatibility, PV systems such as the one owned by the Rappoldt family in Sinsheim, Germany, achieve maximum efficiency. End customers could not be more happy as the system allows them to get the most out of their own solar power.


» „Probably the most important reason for us was that all components in the Fronius system work perfectly together. This provides us with a high energy yield and ensures that we can use all the solar power for ourselves.” «

Daniel Rappoldt, system owner

100% energy self-sufficiency

For the Rappoldt family, this means around 21,500 kWh of solar power annually from their own PV system. By combining hybrid inverters and battery storage, the Rappoldts use their self-generated green electricity day and night and achieve close to 100% energy self-sufficiency during the summer months. Their electric car is flexibly charged with solar power from their own roof or alternatively with mains power, which is charged with variable electricity tariffs at the cheapest times. All thanks to our Fronius Wattpilot charging solution.


“A great feeling to be more independent”

Father-of-two Daniel Rappoldt and his wife expect to cut their energy bill by 1,000 euros a year. “It's just a great feeling to be more independent, to have clean energy and to do something for our children's future. And, as a Swabian, of course, I'm particularly pleased to be saving so much money,” announces proud PV system owner Daniel Rappoldt, summing up his purchase decision and experience with Fronius. He also praises the Fronius System Partnership: “In the end, what won me over was the interaction between the Fronius System Partner and the products, as everything from the organization right through to the installation was straightforward and happened without any hold-ups. We felt in good hands with Daniel and his team and we couldn't be more happy.”


Top quality – and not just the product

Fronius Solar.web is the digital solution from Fronius that allows system owners to keep an eye on all data from the PV system, its current and past electricity production, consumption and battery level at any time and from anywhere. Daniel Fellhauer of Febesol is impressed by the digital solution: “This Fronius tool makes it super easy to check the efficiency of the system. The Solar.web app means Mr. Rappoldt always has visibility into the energy generation levels of his PV system and can use excess energy where and when it is needed.” The digital tool is not just available to end customers, it also facilitates the work of Fronius System Partners such as Febesol along with many other digital applications, at no extra cost whatsoever. Installers can use detailed performance and consumption data to help them optimize their customers' PV systems and so build customer loyalty. In addition to Fronius Solar.web, Fronius System Partners also have access to all the other digital tools from Fronius.
