Procedure for commissioning as a subordinate device

This section describes the procedure of commissioning an inverter that is used in systems with or without System Manager. For commissioning, proceed as described in this section and perform the steps in the given order.

In systems with System Manager, only 1 device can be used as System Manager at a time. All other devices must be configured as a subordinate device and recorded in the System Manager.

If a Sunny Home Manager is available, all inverters must be configured as subordinate inverters ( > Procedure for commissioning in systems with Sunny Home Manager).

A country data set must be set for feed-in operation

To ensure the inverter starts feed-in operation during initial commissioning, a country data set must be set (e.g., via the product commissioning wizard in the SMA 360 app or on the user interface of the product, or via a System Manger).

If no country data set is set, then feed-in operation will be stopped. This state is signaled by the green and red LEDs flashing simultaneously.

The inverter will automatically start feed-in operation only after the inverter configuration is completed.

The country data set must be set correctly.

If you select a country data set which is not valid for your country and purpose, it can cause a disturbance in the PV system and lead to problems with the grid operator. When selecting the country data set, you must always observe the locally applicable standards and directives as well as the properties of the PV system (e.g. PV system size, grid-connection point).

  1. If you are not sure which standards and directives are valid for your country or purpose, contact the grid operator.

The grid type must be set correctly

If you select the wrong grid type, it can cause a disturbance in the PV system and lead to problems with the grid operator.

Procedure

See

Commission the inverter.

Commissioning the Inverter

Establish a connection to the user interface of the inverter. There are various connection options to choose from for this:

  • Direct connection via Wi-Fi

  • Connection via Wi-Fi in the local network

  • Connection via Ethernet in the local network

( > Direct connection via Wi-Fi)

( > Connection in the local network)

If required, change the network configuration on the welcome page. The automatic network configuration recommended by SMA Solar Technology AG via DHCP server is activated by default. Only change the network configurations if the default configuration is not suitable for your network.

Commissioning Assistant

Carry out the configuration using the Commissioning Assistant. Select Subordinate inverter in the device function.

Commissioning Assistant

Commissioning the inverter to be configured as a System Manager, performing the plant-wide configuration using the commissioning wizard. Register all devices in the system and carry out the system-wide configuration.
