Inverters Not Supported in the PV Plant
Inverters that are not supported do not implement the parameters via the Power Reducer Box.
The setpoint of the network operator can however be achieved. For this the status configuration of the
Power Reducer Box must be adjusted so that the output of the supported inverters is more strongly
controlled.
• If the network operator requires an active power limitation of 0%, the unsupported inverters must
be disconnected via a suitable switching unit.
• If in doubt, contact your network operator or the SMA Service Line before you commission the
Power Reducer Box.
No DCHP Mode in the Registered Sunny WebBoxes
In the event of changing IP addresses of the Sunny WebBoxes (e.g. in DHCP networks) the
Power Reducer Box does not function correctly. Reset all Sunny WebBoxes to be registered by the
Power Reducer Box to static IP addresses.
Data Traffic via the RPC Interface
Limitation commands from the Power Reducer Box are sent via the Sunny WebBox RPC interface.
Avoid additional data traffic via the Sunny WebBox RPC interface so as not to compromise the speed
of the limitation commands.
