## What is KOSTAL PIKO CI?

The KOSTAL PIKO CI app is used to commission the inverters of the PIKO CI series and to configure all necessary, system-specific functions. In addition, you have the option of viewing the current performance data of a connected device.

Please note: For configuration, the inverter must be supplied with voltage via the PV side. The DC must be switch on on this purpose!

Open the KOSTAL PIKO CI app and connect to the integrated WLAN of this inverter series. To establish the connection (including the default passwords), follow the instructions in the enclosed quick start guide or the instructions from our download area https://www.kostal-solar-electric.com/de-de/download/download .

You can then make all the necessary settings such as selecting the country policy, changing the network / RS485 / WLAN settings, Solar Portal connections, changing grid parameters, connecting ripple control receivers and parameterising the master / slave inverters.

To prevent unauthorized access to the device, it is recommended to change the default WLAN password of the inverter during commissioning.

You can also use the app to update to the latest firmware version.

### 4/5 — iPad Querformat

*2023-04-21, version 6.10.3*

Da ich die App auch auf dem iPad nutz wäre es ganz gut wenn die Oberfläche sich auch hochkant wie quer darstellen lassen würde. Ansonsten bin ich sehr zufrieden mit der Benutzeroberfläche.
