Zero Export Device and Energy Flow Relay, optimization of self-consumption of self generated energy
The successor model to our popular EFR4001IP: Relays for energy flow measurement type EFR4002IP monitor the current flow between public power grid and generating plant / consumer. Operation is made comfortably via integrated webserver or directly at the device. Measured values are displayed neatly arranged at device on monitor. When the own power plant generates more power than actually is consumed it often is more economical to consume the excess energy self. This is especially reasonable when the difference is high between the price you pay to the grid provider and the price the provider pays for fed in energy.
Many areas suitable for photovoltaics could not be used so far, since only a limited amount of power can be fed in at the grid connection point. In Germany new standards VDE-AR-N 4105:2018-11 allow exceeding this value by up to 66.6% or more installed capacity. The prerequisite for this is that the overbuilt power is consumed and not fed into the grid. In order to still ensure the stability of the system, this can be monitored with EFR4002IP. The same applies to zero export, when no energy at all may be fed into the grid. In this case, the device can be used as an energy flow direction sensor (EnFluRi). The EFR4002IP has been optimized for these functions.
Data exchange with PPC (Power Plant Controller) possible.
Features:
- Switching of up to 3 consumers: the largest consumer, ranked 1-2-3 or combination of 3 consumers (7 levels)
- Switch on and off points. At which energy flow consumers are switched on and off again
- Switch on and off delay of consumers, minimum on time.
- Control of heat pumps (SG-ready), battery chargers, inverters
- For the use of Rogowski coils, please have a look at our EFR4002IPR
