Use of the Inverter’s Digital Inputs Together with a Sunny Home Manager

When an inverter is used in a system together with a Sunny Home Manager, the inverter must be set up as a subordinate device. However, any inverter with a ripple control receiver or remote terminal unit connected via the digital inputs must be configured as a System Manager.

In this configuration, an external active power setpoint can still be implemented by using an I/O module (e.g., MOXA ioLogik E 1214). In this case, the ripple control receiver is connected to the I/O module. The I/O module transmits the setpoints to the Sunny Home Manager via Modbus.
