Device function

It is possible to use and configure the Sunny Island X either as System Manager or as a subordinate inverter.

You carry out the device configuration via the commissioning wizards.

Inverter in Grid-Connected System as System Manager

If you configure the inverter as System Manager, the inverter as a superordinate device in conjunction with an energy meter takes over the control at the point of interconnection and can receive control signals. The inverter can control other subordinate devices, takes over the monitoring of the system and the communication to the Sunny Portal powered by ennexOS.

Subordinate Inverter in Grid-Connected System

If you configure the inverter as a subordinate device, it does not take over independent closed-loop control. The subordinate inverter receives specifications from the System Manager (e.g., an SMA Data Manager or SMA Hybrid Controller) and implements them. Before a subordinate device can be recorded in a System Manager, you must commission all subordinate devices.
