Smart Energy Devices
The EFR device family for the smart grid
EFR offers smart metering and smart grid solutions for end-to-end measurement and grid management tasks and, in this context, offers a coordinated and thoroughly tested range of packages consisting of modern metering devices, smart meter gateways (BSI-CC-1000) and control boxes.
Meters meeting the requirements of the German market are developed and manufactured in EFR’s expertise network with locations in Munich, Wutha-Farnroda (Thuringia), Aachen and Berlin as well as high-performance production partners in the Asian economic area.
EFR’s meter business location in Wutha-Farnroda (Thuringia) plays a crucial role in this. Product management, development, quality assurance, production planning and control and logistics all take place at this location.
A second production facility is being set up in Thuringia to meet the needs of the successful rollout in the German market. Additional production batches, initially in small to medium volumes, will be produced at this location for specific customer requirements. This allows production capacity and lead times to be further optimized in cooperation with the existing production facility.
Electronic electricity meters
The SGM series gives you system-ready meters for measuring active power with residential and commercial customers.
All devices – SGM-C4 and SGM-C2 compact metering devices and the newer SGM-C6 and SGM-C8, SGM-SM eHZ meters or SGM-D4 FNN basic meters – fully meet the legal requirements of the Measuring Point Operation Act (MsbG) and the Bundesnetzagentur (BNetzA) and can be securely connected to an SMGW.
Accessories
EFR’s range of devices is complemented by numerous accessories to provide need-oriented, economically sound solutions. We offer you accessories that meet the requirements of applicable standards and the legal provisions of the MsbG and the Bundesnetzagentur with type test certificates.
Smart meter gateway
The Smart Meter Gateway (SMGW) is the communication hub of the intelligent metering system (iMSys). It bundles consumption and generation data, provides it securely and supports functions such as tariff calculation. As a modern, flexible component, the SMGW enables data exchange via various communication channels, such as Ethernet, cellular network or broadband powerline. Via the CLS interface, it can also send switching commands to control devices, for example for load management, heating control or regulating EEG feed-in.
Control box
Continuous advancements in distributed power generation and the growing popularity of electric vehicles create new applications for this family of devices, such as smart control of distributed storage components and controlled charging of electric vehicles according to dynamic grid status. For these grid-friendly tasks, such as imbalance detection or price-sensitive switching, the EFR GCU-S control box provides distributed intelligence in endpoint devices.
