SMA SUNNY ISLAND 6.0H - Setting the Parameters

5 Commissioning
SMA Solar Technology AG
System DescriptionSI44M-80H-13-MC-IA-en-1030
• Log in as Installer.
• Set the parameter Activation of communication test between the clusters to Off.
5.3 Commissioning an Off-Grid System
5.3.1 Commissioning the Multifunction Relays
In multicluster systems with MC-BOX-12.3-20, multifunction relays 1 and 2 in the master of the maincluster and
multifunction relay 2 in slave 1 of the maincluster are set permanently. Therefore, optional components and functions
can only be controlled via SunnyIsland inverters in the extensionclusters.
• Set the functions of the multifunction relays in the SunnyIsland inverters of the extensionclusters (see operating
manual of the SunnyIsland inverter).
5.3.2 Testing the Load Shedding
Requirements:
☐ The additional load-shedding contactor is connected to a multifunction relay in the master of the extensioncluster.
☐ The battery inverter must be in operation (for information on starting the operation see the operating manual of the
inverter).
Procedure:
1. Activate the user interface of the inverter (see the inverter operating manual).
2. Log in as Installer.
3. Select the parameter Device > Multifunction relay > Operating mode > Operating mode of multifunction
relay.
4. Note the parameter value of the load-shedding contactor.
5. Set the parameter of the load-shedding contactor to Off.
6. If the load-shedding contactor does not discard the loads, carry out the following steps:
• Check the configuration and eliminate the fault.
• Ensure that the multifunction relay is correctly wired.
7. Set the load-shedding contactor parameter to the setting that has been noted down.
5.4 Commissioning a System With Increased Self-Consumption and
Battery-Backup Function
5.4.1 Adjusting the Configuration of the SunnyIsland
If multicluster systems are used with the Grid-Connect-Box for increased self-consumption and as a battery-backup
system, the following must be taken into account: Multicluster systems with Grid-Connect-Box may not be connected to
utility grids that require compliance with the European gird connection conditions in accordance with Regulation (EU)
2016/631 establishing a network code (also known as RfG).
Procedure:
1. For the planned installation site, check whether parameters of the PV inverter for grid monitoring of the
SunnyIsland must be set and adjusted.
2. Check the settings with your grid operator.
3. Access the SunnyIsland user interface (see user manual of the SunnyIsland).
4. Log in as Installer.
