The Solinteg default bus addresses are 247 for Modbus RTU and 255 for Modbus TCP. The Sofar EMS will scan for devices on all addresses from 1 to 255. Therefore, it can take a while to scan for devices.
TIP: If you know the bus address of your Solinteg inverter, you can set it in the Sofar EMS to speed up the scanning process. See the section "Speed up scan process (TCP/RTU)" below.
Modbus RTU (RS485)
Crimp an RJ45 plug on one end of an Ethernet cable according to the T568B wiring standard. Insert the crimped RJ45 plug into the Sofar EMS.
On the other end of the Ethernet cable, connect the blue/white wire to connector pin 13 and the solid blue wire to pin 14.
Finally, connect the USB end of the dongle to an available USB port on the Sofar EMS.
The default modbus bus address or RTU is 247.
Modbus TCP
Modbus TCP is by default enabled on the Solinteg inverters. No additional configuration is required. The default bus address for Modbus TCP is 255. Other common bus addresses for Modbus TCP are 1, 8, 247.
Speed up scan process (TCP/RTU)
If you know the bus address of your Solinteg inverter, you can set it in the Sofar EMS to speed up the scanning process. The example below is for a Solinteg connected using Modbus TCP with bus address 255. By changing the min. bus address to 254, we tell the Sofar EMS to only scan for devices on bus addresses 254 and 255 and to skip the other addresses.
