What People Say About Fenecon

"We have now had the fenecon Home 10 system in operation for 6 months. Commissioning with my solar technician went smoothly. The technology works reliably without any faults, the visualisation is very good and easy to use. I had a query once, which was answered immediately. We are very satisfied!"

Jürgen Menzel

"Mega good technology in the photovoltaic products (storage and inverters). I am delighted with the support. I have already made 2 enquiries and have always been answered within a few hours by technically qualified staff. High praise!"

Marc Armand

"The energy storage system has been in service since 2014. Current versions save much more space. Nevertheless, we still believe we made the right decision back then. Building owners also have storage systems from Fenecon-BYD and are satisfied. That's what counts :-)"

    Hartmut Mihm

    "One of the best storage systems on the market. Super software and great service. I've been working in the PV industry since 2017 and have seen a lot and decided in favour of Fenecon at home."

      Most Common Questions

      A battery energy storage system is worthwhile for any PV system operator whose system is at least large enough to generate the annual amount of energy consumed in the house. A battery energy storage system enables significantly higher self-consumption of self-generated electricity and, if correctly dimensioned, self-sufficiency or self-sufficiency of 50 to 80 %. Consuming a large proportion of the self-generated electricity from your own roof makes investing in a battery energy storage system profitable.
