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.
