Caution
Risk of damage to the unit!
The Solar-Log™ also has an RJ45 socket, which must never be connected to the RJ45 socket on the
inverter.
► Only connect inverters via the RS485/422 Solar-Log™ interface(s).
Procedure
1. If you are making the cable yourself, connect the wires as shown in the following diagram:
Solar-Log™ terminal strip connector RJ45 inverter
Terminal PIN
► 1 ► 7
► 4 ► 8
2. Insert the RJ45 plug into any RJ45 socket on the first inverter.
3. Insert the terminal block connector into the Solar-Log™ RS485 socket.
Connect the inverters to each other
•
Connect using the RS485 data cable with an RJ45 plug
•
Where to connect: RJ45 socket on the outside of the inverter
•
Where to connect HT series: RJ45 socket inside the inverter
Procedure
1. Insert the RJ45 plug into the free RJ45 socket on the first inverter.
2. Insert the other end of the wire into any RJ45 socket on inverter 2.
3. Connect the other inverters to each other in the same way.
Allocate communication address
•
Recommendation: Continuous numbering starting with 1.
•
Setting: Using the inverter operating display
•
Procedure: Start according to the inverter‘s instructions
Notice concerning the RS485 wiring of the SolarMax P series:
The P series from SolarMax does not support RS485 “Daisy Chain” connections. This means that multi-
ple inverters cannot be connected together on the same RS485 bus cable.
For this reason, a maximum of one inverter of the P series can be connected to the respective RS485
ports (A/B/C, max. 3) of a Solar-Log™.
► Alternatively to using the RS485 variation, you can connect multiple P series inverters to the So-
lar-Log™ by means the Ethernet connection to the LAN.
