Special functions

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.
