Solar-Log™ Pro380 CT (RS485 or S0) connection assignments
► As consumption or sub-consumer meter Access to the grid on converter K(P1) - outgoing line to
appliance on converter L(P2)
► As generator / meter for the entire plant Access to production on converter K(P1) - outgoing line to
the grid on converter L(P2)
Solar-Log™ Pro380 CT connection assignments (only RS485)
► As a consumption meter (bi-directional) Access to the grid on converter L(P2) - outgoing line to
house/plant on converter K(P1)
(installation position according to the arrow system)
------------------------------------------------------------------
(Starting with rmware version 3.4.2, the metering direc
-
tion (report) for consumption meters in bi-direction mode
can be set in the Solar-Log™.)
► As a battery meter (bi-directional) Access to production/grid on converter K(P1) - outgoing
line to the battery on converter L(P2)
Cable connection via RS485:
Solar-Log™ terminal strip connector Solar-Log 50 Solar-Log™ PRO380-CT (COM)
Terminal PIN
► 1 1 or 5 22 (A)
► 4 4 or 6 23 (B)
Note
If the meter is the last device on the bus, it has to be terminated at connection block 22 and 23 with a
resistor (120 ohm / 0.25W).
Note
The Solar-Log™ PRO380 CT cannot be connected to the inverters with a single bus.
For this reason, use one RS485 connection for the inverters and one RS485 connection for the So-
lar-Log™ PRO380 CT.
► A combination with a M&T sensor as well as with the Solar-Log™ PRO380 Mod and Solar-Log™
Pro1 Mod in the same bus is possible.
Possible meter operating modes for the Solar-Log™ PRO380 CT via RS485:
•
Battery meter (bi-directional)
•
Total plant meter
•
Sub-consumption meter
•
Consumption meter
•
Consumption meter (bi-directional)
