Reference project

Bosselbacher yard

The horse and inn in the Eifel region stands for a vacation close to nature. The operator wants to make himself independent of electricity uncertainties and therefore relies on his own PV system and battery storage, which gives him 100% self-sufficiency in the best of times.

Profile
Bosselbacher yard

  • Location: Hürtgenwald, North Rhine-Westphalia
  • Agricultural business with horse farm and inn
  • Family business run by the Kaulen siblings

“What I like best about my Voltfang is that I know my electricity price for the next 10 years in advance.” – Swen Kaulen, operator

Advantages for the Bosselbacher yard

Independence thanks to 100% self-sufficiency
Access to self-generated energy around the clock on summer days
Reduction of operating costs
Thanks to reduction in grid consumption
Own consumption increased by 21%
Business benefits from PV-generated electricity thanks to battery storage
150t of CO2 saved over 20 years
The use of second-life batteries conserves resources.

Implemented use cases

Bosselbacher Hof is an outstanding example of how businesses can become independent thanks to a battery storage system and PV system. Self-consumption optimization ensures extremely efficient use of photovoltaic energy, allowing the company to use a considerable proportion of the electricity it generates itself. On sunny summer days in particular, it achieves at least 75% and often even 100% self-sufficiency thanks to the Voltfang PV system and battery storage system. This reduces the amount of electricity drawn from the grid to a minimum and the farm operators enjoy peace of mind thanks to a predictable electricity price and a reliable power supply for years to come.

Self-consumption optimization
Independent and sustainable

Aim of the project

The aim was to efficiently utilize the self-generated electricity. On sunny summer days, the Voltfang battery storage system enables the horse farm to be completely self-sufficient in its electricity supply. The battery discharges in the evening and at night and is automatically recharged in the morning using PV energy. The farm’s guests enjoy a green and unrestricted stay.

Our customized solution

The commercial storage system for the Bosselbacher Hof was designed with a usable capacity of 66 kWh and an output of 50 kW. The system is installed indoors in a fire protection room and is equipped with suitable inverters to ensure efficient power conversion.
