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

Use an Ethernet cable of category 7 (Cat 7, FTP) with a maximum length of 100 m as a network cable (Ethernet 10BaseT, 10/100 MBit/s).

  1. De-energise the mains cable.
  2. Install the as shown in the illustrations at the grid connection point in the house grid.
  3. Guide the Ethernet cable through the LAN cover provided.
  4. Connect Ethernet cable to one of the LAN sockets.
    The second LAN socket is used to continue the network connection to further inverters.
  6. Tighten LAN cover to the specified tightening torque.
    Tightening torque: 3 Nm.
  7. Connect the other end of the Ethernet cable to the router.
  8. Establish a LAN connection from the to the router.
  1. Inverter connected to KSEM.

After commissioning

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

INFO

Info

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

Configuring settings using the KOSTAL Smart Energy Meter user interface

  1. In the , set Modbus settings > Modbus TCP > Slave (Enable TCP Slave) to ON.
  2. To make the home consumption visible in the , in the set Inverter > Solar portal > Activate solar portal to ON.

In this variant, the works as a slave and sends data to the inverter.

 

Configuring settings using the KOSTAL PIKO CI App

  1. Use of the (KSEM) must be configured in the KOSTAL PIKO CI Conf App on the master inverter.
    For this purpose, go to Settings > Inverter settings > Power adaptation/control > KSEM management > Activate/deactivate KSEM > Activate.
  2. The connection between KSEM and inverter is set by going to Settings > Inverter settings > Power adaptation/control > KSEM management > Connection between KSEM and master inverter > LAN.
  3. The installation position is set by going to Settings > Inverter settings > Power adaptation/control > KSEM management > Sensor position > Grid connection point.
  4. The KSEM modbus address is set by going to Settings > Inverter settings > Power adaptation/control > KSEM management > Energy meter modbus address > 1 (standard value in KSEM).
  5. A power limitation of the grid feed-in (e.g. to 70%) must be entered in watts on the Master inverter.
    The active power limitation is entered by going to Settings > Inverter settings > Power adaptation/control > KSEM management > Limitation of the active power to (W).
  6. The KSEM IP address is entered at Settings > Inverter settings > Power adaptation/control > KSEM management > Energy meter IP address > KSEM IP address.
  7. All other inverters connected to the master inverter are configured as slaves. Do not configure any further settings in slave inverters.
  1. Inverters configured.
