Procedure

The following steps must be taken to set up a multiple-inverter connection with KOSTAL inverters:

• Install all KOSTAL inverters in the house grid (see circuit diagram at the beginning)
• Install KOSTAL Smart Energy Meter at the grid connection point (see circuit diagram at the beginning)
• Connect all devices to the KOSTAL Smart Energy Meter and the Internet via LAN
• If a hybrid/battery inverter with connected battery is being used, also connect this to the KOSTAL Smart Energy Meter via the RS485 interface
• If a PIKO MP plus is being used (only for multiple-inverter connection without battery), also connect this to the KOSTAL Smart Energy Meter via the RS485 interface
• When using a hybrid/battery inverter with connected battery, enable storage of excess AC energy from local generation
• Activate Modbus protocol in PIKO IQ, PLENTICORE
• Configure the settling time in the KOSTAL inverters (see guide)
• Set up all KOSTAL inverters in the KOSTAL Smart Energy Meter
• Set power limitation/feed-in limitation for the grid connection point in the KOSTAL Smart Energy Meter
• Assign all KOSTAL inverters and the KOSTAL Smart Energy Meter to a PV system in the KOSTAL Solar Portal
