Installation procedure

The following steps must be undertaken to connect several KOSTAL inverters:

IMPORTANT INFORMATION

notice

Installation may only be carried out by a trained and qualified electrician!

Observe the safety instructions in the operating manual for the inverter, battery and KOSTAL Smart Energy Meter.

Whenever work is carried out on the devices or on the supply lines, the power supply in the house, inverter and battery must be completely de-energised. Refer to the corresponding operating manuals of the relevant devices (inverter/battery/KOSTAL Smart Energy Meter).

  1. Install all KOSTAL inverters in the house grid (see installation overview).
  2. Install KOSTAL Smart Meter at the grid connection point (see installation overview).
  3. Connect all devices to the KOSTAL Smart Meter and the Internet via LAN.
  4. If a hybrid/battery inverter with connected battery is being used, also connect this to the KOSTAL Smart Energy Meter via the RS485 interface.
  5. If a PIKO MP plus is being used, also connect this to the KOSTAL Smart Energy Meter via the RS485 interface.
  6. Activate Modbus protocol in PIKO IQ, PLENTICORE plus and PLENTICORE BI.
  7. If a hybrid/battery inverter with connected battery is being used, enable storage of excess AC energy from local generation.
  8. Configure the settling time in the KOSTAL inverters for feed-in limitation/power limitation.
  9. Activate data transfer to the KOSTAL Solar Portal in all KOSTAL inverters and KOSTAL Smart Energy Meters.
  10. Set up all KOSTAL inverters in the KOSTAL Smart Energy Meter.
  11. Set feed-in limitation/power limitation for the grid connection point in the KOSTAL Smart Energy Meter.
  12. Activate the time server (automated time setting) in the KOSTAL Smart Energy Meter.
  13. Assign all KOSTAL inverters and the KOSTAL Smart Energy Meter to a PV system in the KOSTAL Solar Portal.
