Installation
“Channel and level setup” section
This matrix is used to define the various relay outputs of the ripple-control re-
ceiver. K1-K4 represent the various outputs which are connected to the Solar-
Log™ interface (D_IN_1 to D_IN_4) in the corresponding order.
3 Select Step 1 to 4 to enable feed-in management
4 Close relay at Step 4: Option to send messages by relay output if the sys-
tem is set to 0 per cent.
5 Max. power change: The power can be reduced in steps. This prevents
large power fluctuations.
“Network link” section
In large systems with more than one Solar-Log™, these can be networked to-
gether in order to manage the larger number of inverters.
6 Another Solar-Log™ is added by entering the IP address.
“Reactive power control” section
In Solar-Log
1000
PM+, three different shift factors can be set for reactive power
control:
– Fixed shift factor cos φ (Phi)
– Variable cos φ based on the current feed-in power value (P/Pn characteristic)
– cos φ controlled through a ripple-control receiver
Here, up to 4 potential-free contacts are available for signalling.
The 5th contact for the cos φ = 1 signal does not need special wiring, and is
therefore automatically available.
