Connecting the KOSTAL Smart Energy Meter

  1. De-energise the mains cable.

  2. DANGER

    danger

    Risk of death due to electrical shock and discharge!

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

  3. Install the KOSTAL Smart Energy Meter as shown in the illustrations at the grid connection point in the house grid.
  4. Feed the Ethernet cable on the inverter through the COM2 cover and seal it with sealing ring and union nut. Tighten union nut to the prescribed torque.
    Torque: 8 Nm (M25).

  5. INFO

    Info

    LAN cable requirements:

    • CAT7
    • Max. 100 m
  7. Connect Ethernet cable to one of the LAN sockets in the COM2 connection panel. The second LAN socket is used to continue the network connection to further inverters.
  8. Mount COM2 cover cap.
    Torque: 1.5 Nm
  9. Connect the other end of the Ethernet cable to the router.
  10. Establish a LAN connection from the KOSTAL Smart Energy Meter to the router.
  11. In this variant, the KOSTAL Smart Energy Meter works as a slave and sends data to the inverter.
  12. In the KOSTAL Smart Energy Meter, set Modbus settings > Modbus TCP > Slave (Enable TCP Slave) to ON.
  13. To make the home consumption visible in the KOSTAL Solar Portal, in the KOSTAL Smart Energy Meter set Inverter > Solar portal > Activate solar portal to ON.

After commissioning, the following settings still have to be configured in the KOSTAL PIKO CI app.

  1. The use and installation position of the KOSTAL Smart Energy Meter (KSEM) must be set in the KOSTAL PIKO CI app on the Master inverter.
    This can be set under Settings > Inverter settings > Power adaptation/controls > Energy management > Power limitation function > KSEM and Settings > Inverter settings > Power adaptation/controls > Energy management > Sensor position > Grid connection point (default value).
  2. The IP address of the KOSTAL Smart Energy Meter can be set in the KOSTAL PIKO CI app under Settings > Power adaptation/controls > Energy management > IP address of energy meter.
  3. A power limitation of the grid feed-in (e.g. to 70%) must be entered in watts on the Master inverter.
    This can be set under Settings > Inverter settings > Power adaptation/controls > Energy management > Limitation of the active power to [W].

  4. INFO

    Info

    If power limitation is carried out in combination with the KOSTAL Smart Energy Meter, power limitation via a ripple control receiver (RCR) is not possible and must be deactivated.

  5. The KOSTAL Smart Energy Meter is connected to the Master inverter. If not already done, configure this inverter as a master LAN.
    This can be selected in the KOSTAL PIKO CI app under Settings > Communication settings > Master/Slave settings > Master LAN.
  6. All other inverters connected to the master inverter must be configured as Slave. The following default settings should be checked for all slave inverters:
    Master/slave settings: Slave
    Power limitation function: deactivated
    Sensor position: Grid connection point
    Activate ripple control receiver: OFF
