Several energy supply companies offer the owners of PV systems the possibility of regulating their system with variable active power control and thus increasing the feed-in into the public grid to up to 100%.

INFO

Info

In some applications, the digital may be regarded as a cost-effective alternative to the ripple control receiver. Here the feed-in may well be limited by the energy supply company, but the inverter controls the flow of energy (self-consumption in house grid and feed-in to the public grid) in such a way that the self-produced energy is not lost or loss is kept to an absolute minimum.

Ask your energy supply company or installer what application rule applies to you or whether there is an alternative (e.g. smart meter) better suited to you.

If a ripple control receiver is already connected to another KOSTAL inverter in your home network, you can use the control signals of this ripple control receiver.

DANGER

danger

Risk of death due to electrical shock and discharge!

De-energise all devices and secure them against being switched on again.

INFO

Info

Requirements of communication cable:

  • Wire cross-section from 0.34 to 1.5 mm² (rigid) or 0.34 to 1.0 mm² (flexible)
  • Length max. 30
  • Length of stripped insulation approx. 5 mm
  1. De-energise the mains cable.
  2. Fit ripple control receiver in control cabinet or power distributor.
  3. Correctly route the communication cable from the inverter to the control cabinet and connect following wiring diagram provided by manufacturer.
  4. Pass the communication cable through the cover for the COM2 connection panel. Seal connection with sealing ring and union nut.
  5. Connect the communication cable to the plug connector for the communication interface. Please note the pin assignment.
    Tightening torque: 0.2 Nm.
  6. Connect plug connector on inverter to communication interface in COM2 connection panel.
  1. The ripple control receiver is connected.

After commissioning

  1. Open the KOSTAL PIKO CI Conf App and connect to the inverter to which the ripple control receiver is connected.
  2. Activate the ripple control receiver in the KOSTAL PIKO CI Conf App by going to Settings > Inverter settings > Power adaptation/control > Ripple control receiver (RCR) > Activate ripple control receiver > ON.
  3. Configure the connection type between master and slave inverter (LAN or RS485) on the master inverter by going to Settings > Inverter settings > Power adaptation/control > Ripple control receiver (RCR) > Connection between master inverter and slave > LAN or RS485
  4. Set switching values for the ripple control receiver by going to Settings > Inverter settings > Power adaptation/control > Ripple control receiver (RCR) > RCR active power / RCR reactive power / RCR power factor.
  1. The ripple control receiver has been configured.
