By integrating the PV system into the new charging infrastructure, the company can save costs and energy while protecting batteries and the environment.

SCS Scheiffele-Schmiederer (SCS for short) was founded in 1841 as a timber mill in Dillingen and has since developed into a timber wholesaler with production facilities and six branches in Bavaria and Baden-Württemberg. From here, the family business supplies its customers in southern Germany. According to the company, it attaches particular importance to sustainable and resource-conserving management: Among other things, sustainable building materials were used in the construction of the new company headquarters in Gundremmingen. SCS uses collected rainwater as process water, relies on efficient logistics processes and supplies its electric vehicles and forklifts with solar energy from its own roof.

Charging technology on the test bench

SCS recently took a closer look at the charging technology of its industrial trucks. At its site in Gundremmingen, SCS operates a fleet of eleven electric industrial trucks, which are used to transport wooden beams, boards and profiles in the warehouse and for shipping on the company's own trucks. The logistics managers were looking for efficient charging technology that could safely and sustainably charge the variety of batteries used with and without electrolyte circulation. "The FFZs are essential for smooth operations and must be highly available. We were dissatisfied with the availability of the FFZ and the batteries, and considered whether such a high charging current was really necessary," explains Karl Schmiederer, Managing Partner at SCS. As a result, Fronius was contacted as a technology partner.

The experts from Fronius carried out a comprehensive analysis on site and developed a solution together with the customer. "Thanks to funding support from the Federal Office of Economics and Export Control, we were able to standardize the charging infrastructure and ensure that it complies with the latest standards and is operated economically," adds Matthias Leibold, Technical Manager at Fronius Perfect Charging.

Charging electric forklifts: Converting the technology

The Selectiva 4.0 chargers offer intelligent functions and a gentle, energy-efficient charging process for lead-acid batteries. They are versatile and can charge different types of batteries, which simplifies charging processes and saves costs. "Specifically tailored to SCS's application situation, this meant that 16 Selectiva 4.0 16 kW chargers supply the FFZ with energy generated by the PV system with the 16 Tauro Eco 100 3 D and two Tauro 50 3 D inverters on the hall roof," explains Matthias Leibold.

One of the advantages of Fronius charging technology is the ability to network the chargers with the Charge & Connect software. Thanks to intelligent networking, the chargers can be easily connected to the customer's own inverters. This allows the customer to transparently monitor the kWh consumed per charging station and the kWh generated by the PV system. The installation of 16 Tauro-Eco-100-3-D and 2 Tauro-50-3-D inverters sets new standards in sustainable energy generation at the Gundremmingen site. Together with the more than 5,000 solar modules installed, the Fronius inverters make a major contribution to the energy self-sufficiency of the entire group of companies, which operates a total of two PV systems with a total capacity of 4 MWp. "This installation is a symbol of our commitment to a sustainable future and our efforts to make a real difference through innovation and quality," Karl Schmiederer sums up.
