Preserving the proven. Shaping the new.

Let us energise your ideas!

Energy suppliesrequire dependable quality, which can be counted on. This is particularly important in the storage of electricity, a key technology in modern and future power supply concepts. In the development and construction of electrical systems, we rely on close partnerships with our suppliers for many years.

Our series-produced components offer high reliability andare widely utilized in many electrical system operations worldwide.Through the diversified requirements of our customers emerge out-of-the-ordinary and special solutions suitable for a particular application.

Power Electronics

To ensure reliable tasks in the field of high-performance energy supply, modular components are employed with highest investment security. The Pfenning Electrical Equipment Co., Ltd. as a SIEMENS Solution Partner is hereby placing its emphasis on the flexible, numerouslyand globally approved SINAMICS converter series as a base. It incorporates specially amended and in-house adapted modifications.

High dynamics and ease of handling thus help many applications today and in the future to become an economic investment. This technology turns the E-SpeicherWerk power storage into a modular, expandable system. The growing variant diversity within its intended purpose can thus be covered at all times.

Battery Technology

Lithium-ion battery technology presents itself as a very suitable basis for the application of high-performing storage systems. In the exact selection of specified requirements were close partnerships with cell manufacturers established.

The knowledge has been considerably enlarged by deep insight and trust. Your individual needs can thus be evaluated through expert knowledge in-house, and one of the most important decisions to be made: Does cell technology fit your requirements.

The perfect blend

Decades of experience and know-how in electrical systems engineering and the area of direct and alternating currents serve as an excellent basis for making the right decisions. These findings are an important factor for the proper battery management system (BMS). Only through the professional approach of treating batteries and BMS as a unit is an intelligent system being formed at the highest level.

The own engineering of BMS permits a future-oriented realization of varying requirements. The E-SpeicherWerk power storage system open to solutions in different cell technologies. This in turn creates reliable, long-lasting and extensive battery storage systems for a variety of applications.

Control Technology

When referring to Bavarian professional quality in control technology from Amberg is SIEMENS´ SIMATIC globally present. Innovation and quality in the S7 controller are found in many thousands of machines. The in-house software engineering group of Pfenning Elektroanlagen GmbH in Ochsenfurt/ Germany has also designed its own firmware to meet the requirements of the E-SpeicherWerk power storage system.

There are many arguments such as modular expandable, vibration resistant, maintenance-free, scalable and long-term compatible - but one convinces: Experience since 1979 - SIMATIC.

We can meet different requirements in terms of interfaces and protocols for the perfect integration into your system.

It goes without saying that we will of course also map VDEW protocols and the established, international IEC 61850 standard for communication between other network subscribers in different power plants.
