Procedure:
1. Switch to expert mode on the Sunny Remote Control (see the Sunny Island inverter operating manual).
2. If frequency-dependent control of active power feed-in is not permitted, set the parameter 232.41 P-WCtLHzMod
to Off.
3. If your grid operator specifies a maximum grid feed-in per line conductor, set the parameter
210.03 InvChrgCurMax to the value specified by the grid operator.
7.3.5 Adjusting the Configuration for Switzerland
The following limiting values must be adjusted in order to meet the requirements of the grid operators in Switzerland:
• Maximum power frequency
• The upper frequency difference for valid grid connection
• Minimum observation time for grid voltage and frequency before grid connection
If your grid operator specifies a maximum grid feed-in per line conductor, you must reduce the discharge/charging
current (default setting in the Sunny Island is 20.0 A).
Requirement:
☐ The extended configuration must be performed within the first ten operating hours of the Sunny Island inverter,
otherwise an SMA Grid Guard code is required in order to change grid-relevant parameters (application form for
the SMA Grid Guard code available at www.SMA-Solar.com).
☐ The country data set of the Sunny Island inverter must be set to VDE-AR-4105 (see Section 7.1 "Basic Configuration
of the Sunny Island Inverter", page 40).
Procedure:
1. Switch to expert mode on the Sunny Remote Control (see Sunny Island inverter operating manual).
2. Set the parameter 232.07 GdFrqMax to 50.2 Hz.
3. Set the parameter 232.15 GdFrqMaxDel to 0.05 Hz.
4. Set the parameter 232.08 GdVldTm to 30 s.
5. If your grid operator specifies a maximum grid feed-in per line conductor, set the parameter
210.03 InvChrgCurMax to the value specified by the grid operator.
7.4 Adjusting the Configuration of the PV Inverters
Countries in which the configuration should be adjusted
In battery backup systems, the active power of the PV inverters should be controllable depending on the frequency (see
Planning Guidelines "SMA Flexible Storage System with Battery Backup Function"). If your grid operator prohibits control
of active power feed-in in the case of overfrequency, you can also use the PV inverters without changing the configuration.
SMA Solar Technology AG recommends activating the frequency-dependent control of the PV inverters.
