Overview
•
Integrated interface
•
Where to connect: Round pin plug on the outside of the inverter.
•
3-pin wiring
•
Communication address must be allocated.
•
Inverters must be grounded otherwise this could lead to problems with inverter detection.
•
Installation steps
•
Switch off the inverters and Solar-Log™
•
Connect inverters to the Solar-Log™
•
Connect the inverters to each other
•
Allocate communication address
Connect inverters to the Solar-Log™
•
ready-made data cable (optional extra; not supplied)
or
•
self-made, shielded 3 wire data cable and terminal block connector.
Procedure
1. If you are making the cable yourself, connect the wires as shown in the following diagram:
