6 Configuring the Module
6.1 Information on Module Configuration
Active power reduction to one of the 16 values set is realized within five seconds in the inverter.
Grid disconnection is possible within two seconds. In order to block an entry combination, the value
−1% must be set in the communication product (see table on page 21). This enables unassigned entry
combinations to be blocked.
If the grid operator does not permit the inverter to still feed in a low amount of active power when
limited to 0%, you must set the following parameter for grid disconnection. Setting this parameter
additionally opens the grid relays at a command of 0%. As a result, the inverter disconnects from the
utility grid and grid feed-in is no longer possible. Depending on the type of communication and the
communication product used, the parameter name may vary:
When the parameter is activated (Yes), the inverter disconnects from the utility grid when the signal
"0%" is issued. When the parameter is deactivated (No), the inverter continues to feed in with
minimum power when the signal "0%" is issued.
You can set the operating mode of the multifunction relay by means of a communication product
(for a detailed description of the operating parameters, see the Technical Description "Measured
Values and Parameters" at www.SMA-Solar.com).
6.2 Setting the Operating Mode Active Power Limitation or
Remote Shutdown
Depending on the ordered country option, the operating mode Active power limitation or Remote
shutdown is activated by default.
Procedure:
• If you wish to use the operating mode Active power limitation, select the parameter
Operating mode of Power Control Module/PCM-OpMode and set it to the value Active
power limitation/ModWMax.
• If you wish to use the operating mode Remote shutdown, select the parameter Operating
mode of Power Control Module/PCM-OpMode and set it to the value Remote
shutdown/ModRemOff.
