        Energy Storage on LV Grids

        Planning, Installation and Operation of Battery Storage Systems

        by Marc Fengel

        To ensure availability in future decentralized energy generation and consumption, electrical energy storage systems are inevitable. They store electrical energy of generation plants (e.g. the photovoltaic system) when sun is shining and make energy available again at any time. That means that energy is consumed where it is generated, reducing grid losses and creating self-sufficiency. However, this also increases the complexity of systems. Which makes it more difficult for planners, installers and operators to construct such systems safely and in accordance with the recognized rules of technology, to integrate them into existing systems and to operate them safely. This book deals with the various storage concepts, taking into account the currently valid installation regulations. It serves as a guide for planners, installers and operators on the complex topic of storage systems. The following topics are included: Terms and definitions Application of technical regulations VDE-AR-E 2510-2 Operating modes Protective measures in electrical plants with storage Erection of generating plants Requirements for grid connection Installation of storage tanks Testing of storage tanks

        Compliant Installation of Photovoltaics

        by Heinz-Dieter Fröse

        The number of installed photovoltaic systems is constantly increasing; the trend is clearly upward. However, inspectors of these systems repeatedly find a large number of defects that impair the systems' functionality. Consequences are considerable damage during natural events or through many years of operation. This book provides installers with comprehensive information on: Preparatory measures for the installation of a photovoltaic system, Selection of products, Installation regulations, Electrotechnical installation guidelines, Regular inspections, Work safety, Important aspects of practical implementation, Electrotechnical testing and documentation of photovoltaic systems, and Maintenance of photovoltaic systems. The updated 4th edition taks all current standards, regulations and guidelines into account.

        Energy Consulting for Buildings

        Basics, Systems, Usage

        by Martin Pfeiffer, Achim Bethe, Dirk Fanslau-Görlitz, Holger Janßen, Gerd Kaellander

        The regulations of the German Building Energy Act (GEG), which have been in force since 2021, and the energy situation, which became more stringent in 2022, make the topic of "energy consulting of buildings" a top priority for all those who are concerned with appropriate measures for new and existing buildings.This book serves as a decision-making aid for choosing the appropriate energy modernization and new construction measures for residential and non-residential buildings. In particular, it addresses the following topics: Building-related dimensions of sustainability, building life cycles Fundamentals of heat transfer as a central phenomenon of energy efficiency. Building energy planning with a focus on ultra-low energy buildings: legal requirements, energy technology, automation through digital regulation and control options, and quality management including testing and certification procedures Energy consulting for buildings according to VDI 3922 sheets 1 - 3 and concretely realizable measures for new and existing buildings Building energy management, especially in the context of the Continuous Improvement Process (CIP) as well as according to selected aspects of DIN EN ISO 50001

        KNX/EIB Engineering Tool Software

        Safe Installation and Changeover from ETS5 to ETS6

        by Michael Körmer, Willi Meyer

        Smart home solutions are in vogue, but require precise knowledge of the underlying hardware and software. Those who do not deal with ETS programming on a daily basis sometimes find it difficult. Instead of relying on memory and colleagues' knowledge for setup, this book helps as a step-by-step guide: the overall process of programming and commissioning KNX/EIB projects based on the current Engineering Tool Software (ETS) is covered. This enables you to follow all the necessary steps before, during and after processing with ETS5 and ETS6 "in one piece". The book takes into account the current state of the software based on ETS5 as well as ETS6. From the determination of requirements to the documentation, the necessary knowledge is conveyed. All actions with the discussed software tools are illustrated by screenshot, which ensures a good comprehensibility. For practical understanding, the complete project of a single-family house is also presented step-by-step and richly illustrated. This book will help you especially with the following questions: What are the basics of KNX hardware and software? What basic knowledge do I need specifically for ETS5 and ETS 6? What are the differences and similarities between the two KNX tools? How do I lead an extensive KNX project to success? (Practical example)

        Building Biology Measurement on EMF

        Basics of Field Theory, Practice of Field Measurement Techniques

        by Martin H. Virnich

        The teaching of well-founded, practice-oriented EM field measurement technology on a scientific basis is the central concern of Dr.-Ing. Martin H. Virnich's book. In an easily understandable form and without "higher" mathematics, the author clearly presents the fundamentals of field theory in a depth necessary for practice. Core topics of his book are the following aspects: Physics of EM fields, Measurement of vector fields, Alternating electric fields (low frequency and DC fields), Alternating magnetic fields (low frequency and DC fields), Electromagnetic waves (high frequency), "Dirty Power", as well as The alteration of the natural EMF spectrum and its consequences. New to this 2nd edition is a detailed section on 5G NR, which deals with the current mobile communications standard and its many manifestations. In doing so, it dispels a number of myths surrounding 5G.
