5. Select the parameter Grid Monitoring > Grid monitoring > Country standard > Country standard set and
set it to the value DE VDE-AR-N4105-MC.
6. To adjust the parameters for grid monitoring on the SunnyIsland, carry out the following steps:
• Enter the SMAGridGuardCode (see installation manual of the SunnyIsland).
• Adjust the parameters for grid monitoring as agreed with the grid operator (see user manual of the
SunnyIsland). As a result, the parameter value is changed from Grid Monitoring > Grid monitoring >
Country standard > Country standard set to SMA Adjusted-MC.
5.4.2 Adjusting the Configuration of the PV Inverters
In systems with increased self-consumption and battery-backup function, the active power of the PV inverters should be
controlled frequency-dependent. The manner of the frequency-dependent active power limitation complies with the
locally applicable standards and directives.
Requirements:
☐ The firmware version of the PV inverters must support the frequency-dependent control of active power (for “PV
inverters,” see the planning guidelines “"SMAFlexibleStorageSystem with Battery Backup Function" at
www.SMA-Solar.com).
Procedure:
1. For the planned installation site, check which country data set of the PV inverter corresponds to the grid operator's
requirements and supports frequency-dependent regulation of the active power.
2. Ensure that the country data set has been configured correctly at the PV inverter.
5.4.3 Commissioning the System with Increased Self-Consumption and Battery-
Backup Function
The intermediate storage of PV energy is activated automatically.
Regarding the system with increased self-consumption and battery-backup function, the parameter Functions for
grid/offgrid operation must be set to Functions for grid operation during basic configuration (see
Section5.1.2, page28). The intermediate storage of PV energy is thereby activated automatically.
Deactivation of the intermediate storage of PV energy during certain charging procedures
When using lead-acid batteries, the SunnyIsland carries out full and equalization charges on a regular basis (see
technical information "Battery Management" at www.SMA-Solar.com). As a result, the service life of the battery is
increased. During full and equalization charges, the intermediate storage of PV energy is deactivated and
electricity may have to be purchased to perform the full and equalization charges.
Requirements:
☐ The preparations for the commissioning at the Multicluster-Box must be completed.
☐ The preparations for commissioning at the Grid-ConnectBox must be completed (see the operating manual for the
Multicluster-Box and operating manual for the Grid-Connect-Box).
☐ The function of the residual-current devices and the tie switches must be checked (see the operating manual for the
Multicluster-Box and operating manual for the Grid-Connect-Box).
☐ The basic configuration of the SunnyIsland must be implemented for Island mode.
Procedure:
1. Attach a clearly visible information about the installed battery-backup system to the AC main distribution board.
2. Commission the PV system.
3. To deactivate the intermediate storage of PV energy, select in the display group on the master of the main cluster
Device > device > Self-consumption the parameter Rise in self-consumption switched on and set to No.
