Electrical power-generating facilities
In order to get the most out of photovoltaic systems and to make clever use of the self-generated energy, we have developed special measuring and monitoring devices.
Devices type UFR are used for grid- and plant protection at the connection between the in-house generation system and the public network. They monitor voltage, frequency and other parameters.
Devices type EFR used as zero-export devices switch off within <400 ms at inadmissible feed-in. Another application is the optimization of self-consumption. If there is a high level of self-generation, consumers are switched on, i.e. the energy is consumed when it is cheaply available.
