EFR will be represented again at E-world in Essen this year, on a stand shared with Theben AG and Easymeter GmbH. The latest version of the Smart Grid Hub communication module will be on show, with integral Web-server, which makes energy consumption data available to PCs via an in-house network. EFR is also presenting products for control of regenerative units, based on the tried and trusted long-wave system, which offers nationwide, cost-effective and network-independent management of feed-in energy in accordance with the guidelines of the EEG (Renewable Energy Law).
