This guide covers the listed TL-G3, TLM and TLX families. Connector layouts and communication options can differ between model revisions, so verify the exact model label before wiring.
Device Type 1100-3300TL-G3 3000-7500TLM 10000-40000TL 5000-80000TLX-G3 100000-125000TLX-G4 7000-10500TLM-G3
Warning Warning
Most of the devices can communicate using modbus TCP. This is not valid for the series "SOFAR 1...40KTL"
Some inverters require specific firmware that is limited to certain distributors. Consult your distributor in case of doubt.
Connect the inverter to your internet network using the "SOFAR SOLAR ETHERNET STICK LSE3".
For correct ethernet wiring: Follow the the guidelines for ethernet wiring .
Info RS485 Wiring For correct RS485 wiring: follow the RS485 wiring guidelines . If the wiring shown in the table below is incorrect, please let us know. There is no general industry consensus on the use of A and B for RS485 polarity, so the naming may be counterintuitive for some devices.

Warning NOTE: RS485 Device Addresses You MUST give each device a unique address on the RS485 bus. Check the device manual for instructions. Use lower addresses first (1, 2, ...) because the Sofar EMS will find them faster! For each device, it is generally recommended to keep the factory-default baud rate, parity, and stop bits. The Sofar EMS will scan those first. External inverter control must be activated in the configuration menu of the inverter via the LCD screen.
