5.4 Information on Module Configuration
Active power reduction to one of the 16 values set is realised 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 16). This allows that unassigned
entry combinations can be blocked.
If the network operator does not allow that the inverter still feeds 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%. The inverter disconnects from the
electricity grid and grid feed-in is interrupted. 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 electricity 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.
