Relays for energy flow 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.

 

Zero-Export-Device or limiter:

  • Switching off the power generation system or parts of it if the permissible feed-in power is exceeded with relay K3
  • Switching on consumers or reducing generators before it comes to that by means of regulating with an analogue output or switching loads with relays K1 and K2
  • Energy flow direction sensor (EnFluRi sensor) and feed-in limitation < 0.1s

Functions

  • 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

 

Suitable current transformers:

  • Current transormers scaleable up to 2.400 A, secondary 1 A or 5 A (for Pav,e min. class 1) for example ZIEHL Type AS or WS
  • Compact CTM7, 64/1 A, Kl. 1, 0,5 VA
