Device function of Sunny Boy Smart Energy

In systems with multiple inverters, you have the option of using and configuring the Sunny Boy Smart Energy either as a System Manager or as a subordinate inverter.

When using a Sunny Boy Smart Energy as a System Manager, you can integrate up to 5 additional devices (e.g. 3 Sunny Boy Smart Energy, 1 PV inverter and 1 energy meter) into one system. It is important to note that there may be a maximum of 3 batteries in the system.

Only 1 Sunny Boy Smart Energy can be used in systems with Sunny Home Manager. The Sunny Boy Smart Energy must be configured as subordinate inverter.

You can set the device function using the commissioning wizard.

Inverter as System Manager

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

Inverter as subordinate

If you configure the inverter as a subordinate device, there is no independent closed-loop control or open-loop control at the point of interconnection. The subordinate inverter receives specifications from a superordinate device (e.g. inverter as System Manager or Sunny Home Manager) and implements them. It should be noted that the Sunny Home Manager cannot be used for reactive power control of the subordinate inverters.
