Ziehl EFR4001IP Generator/grid monitoring relay No. of relay outputs: 3

Energy flux relay EFR4001IP

EFR4001IP power flow relays monitor the flow of current between the consumer and the public grid (at the mains connection point). The operation is done comfortably with the integrated web server via the IP interface or via LCD clear text display directly at the device. Measured values are clearly displayed on the display or on the screen. Many areas suitable for photovoltaic systems could not be used up to now, as only a limited power can be supplied at the network connection point.With the certification by VDE-AR-N 4105:2018-11, two thirds or more additional generation power can now be installed when monitored by the EFR4001IP than the mains connection permits.
