Installation steps
• Switch off the inverters and Solar-Log™
• Connect inverters to the Solar-Log™
• Connect the inverters to each other
• Allocate communication address
Note:
The inverter's communication connection is then changed to the from the round socket to
RJ45. Currently, the SG1,5KTL is still supplied with round sockets.
Connect inverters to the Solar-Log™
The wiring is done using a
•
self-made, shielded 2 wire data cable with round plug and terminal block connector.
