To enable the inverters in the system to implement the grid management service setpoints of the
Cluster Controller, you will first need to set the corresponding parameters in the inverters.
Requirement:
☐ You must have received a personal SMA Grid Guard code (application form for the
SMA Grid Guard code available at www.SMA-Solar.com, for further information on the
SMA Grid Guard code, see Section 15.5, page 87).
Procedure:
1. Log in to the Cluster Controller as Installer.
2. Select the SMA Grid Guard symbol ( ) in the status bar.

Setting Explanation
cosPhi, specified by PV system
control The inverter only implements cos Phi setpoints.
Q specified by PV system control The inverter only implements Reactive power in %
setpoints.
