The inverter sends the PV system's yield data and event messages to the KOSTAL Solar Portal via the Internet. The information is stored in the KOSTAL Solar Portal. You can view and call up this inform- ation via the Internet.
For proper operation in a larger solar system, the normal measures of regular system monit- oring are fully sufficient. In particular, tracking the energy obtained via data loggers, the KOSTAL Solar Portal or en- ergy meters will quickly indicate irregularities. Events during operation are also logged.
KOSTAL PIKO CI app. Procedure Use a smartphone or tablet with the KOSTAL PIKO CI app installed. Proceed as follows: Enable the Bluetooth function on your tablet or smartphone. Launch the app.
Operational statuses and error causes are reported as a combination of LED display and event code. The event code is shown in the KOSTAL PIKO CI app or in the KOSTAL Solar Portal. Determine the type of event using the table below ( Event messages, Page 121).
