23�2�5 Remote controlled active power reduction with the calculation of self-
consumption (only Solar-Log™ PM+)
This function is an enhancement to the Remote controlled active power reduction function described in
the previous chapter. This function does not correspond to provisions of the German EEG laws and has to
be arranged with the grid operator before being used.
Note
The Solar-Log PM+ needs to be
linked to a consumption meter to implement this function. Please note the instructions in
chapter”12.5 External power meter”.
The configuration of this corresponds to that already described for the remote controlled active power
reduction.
The instruction for integrating the meters into the electric wiring of the house or building are found in the
appendix.
Note
Self-consumption is taken into account with a command (less than 100% and greater
than 0%). The inverter(s) supply a higher output than the command value by taking the
current consumption into account.
Self-consumption is not taken into account with the 0% command value. As a safeguard
here, the plant is always limited to 0%.
23�2�6 70% fixed reduction
By activating this menu item the inverter(s) are controlled to be fixed at 70% of the installed DC power.
Enter the
Maximum AC Power and Connected Generator Power as reference values in the Configura-
tion | Basic | Inverter
menu.
The maximum power output for the inverters can be calculated from the connected generator power value
that has been entered.
Procedure
•
Select 70% fixed reduction.
•
Select the interface of the inverter that is to be reduced.
•
SAVE settings.
Note
Changes to the Maximum AC Power of the inverter in Configuration | Basic | Inverter
menu are disabled.
