BENNING Elektrotechnik und Elektronik: One-Stop-Shop Experience for Safe Utilisation of Energy Resources

For almost a century, BENNING has been manufacturing and developing smart solutions for converting energy into multi-purpose, storable energy. It is focused on the true uninterruptible power supply (UPS) and energy storage markets, offering sustainable, safe, and efficient solutions to its customers worldwide. The company takes a unique industrial market approach by incorporating UPS into its islanding technology, a strategic move that ensures continuous power supply.

This innovative approach underpins the company’s commitment to providing uninterrupted, dependable operations, reinforcing its status as a leader in the energy conversion industry.

“We ensure that a consistent and stable power supply is maintained at the output regardless of fluctuations or disturbances in the input,” states Alexander Proemel, Industrial Product Manager at BENNING.

The firm provides its clients with an advanced, hot-swappable, modular and highly scalable storage system based on an AC UPS with real UPS functionality. BENNING’s real UPS is a double-conversion UPS architecture with a rectifier, a DC link, and an inverter. This system is notable for its ability to incorporate a bi-directional charger, which promotes dynamic energy management and allows for the execution of battery capacity tests. In addition, the battery port serves as a critical junction for the battery and the inverter, which is central to the system’s architecture.

BENNING’s innovative system efficiently generates and administers grids, making it particularly useful for applications like integrating islanding PV systems. The bi-directional charger also enables clients to redirect excess energy back to the grid, engaging in peak shaving and optimising energy consumption.

The firm’s intelligent solution is designed for highest system availability, thereby catering to industrial applications, regenerative produced power and microgrids. The system’s control strategy is instrumental in moderating the battery’s decay rate, extending its cycle life, and improving the energy storage system’s economic feasibility. This strategic approach significantly accelerates the investment’s break-even time. The system’s transformerless design ensures maximum efficiency, allowing the UPS to operate effectively with a 400-volt input grid without additional assistance.


BENNING’s solutions support a diverse array of battery technologies and are compatible with manufacturers, offering a versatile battery voltage window. This flexibility ensures broad compatibility with various energy storage solutions, allowing customers to tailor the system to their own needs. The firm also offers the option to incorporate redundant modules into its system to ensure uninterrupted operation even if a unit fails. The UPS is designed to enable decentralised deployment within the client’s infrastructure, with scalability options ranging from 20 kilowatts to several megawatts per unit, allowing for strategic placement across different processing plants and operational sites.

Further catering to its customers’ load management needs, the firm’s energy storage systems include a true UPS function and an onboard energy management system (EMS). This gives its clients integrated functionality and the option to integrate external EMS solutions from trusted partners for enhanced features like AI or cloud services. This approach optimises the overall cost of ownership while expediting the client’s revenue generation.

BENNING offers comprehensive, turnkey and containerised solutions that meet the data centres’ dynamic requirements, emphasise sustainability and optimises energy management across various applications. The firm supplies test and measurement equipment, DC-DC converters and OEM power supplies. The firm also extends battery backup and integrates the system with solar installations. This ensures prolonged load support, minimises battery reliance and capitalises on user-generated solar power, contributing to reduced carbon emissions without compromising efficiency.

The firm provides a full spectrum of services, including system installation, commissioning, on-site training and EMS setup. Each step is tailored to the client’s specific needs, starting from sizing the converter and batteries based on historical load profiles. Once the service is completed, BENNING maintains dedicated customer support, offering a direct hotline for immediate assistance.

Established as a “quality leader” since 1938, BENNING presents its customers with a comprehensive portfolio of storage solutions, delivering a holistic one-stop-shop experience. The company caters to multiple requirements, from basic load management to advanced islanding operations, aiming maximise efficiency, reduce costs and yield rapid investment returns for its clients.
