Use the guide that matches the data route available at the installation. A local or push connection and a manufacturer API have different credentials, network requirements, and update behaviour.
The installed datamanager and available interface determine whether the project uses a local, push or cloud connection.
Before commissioning, record the exact Fronius model and firmware, verify the connection method, and compare SmartgridX power and energy values with the inverter interface. Also check the time zone and continuity of historical data before enabling reports or alarms.
