3. Setup and Installation

3.1 Physical Installation

Follow these steps to connect the Wi-Fi Plug Pro-03 to your solar inverter. The connection method depends on your specific Datalogger Model and inverter interface:

1. **Identify Interface**: Find the corresponding interface code on your inverter based on the Datalogger Model table below. This will determine the correct connection method.

   Datalogger Model	Interface Code	Connection Type
   Wi-Fi Plug Pro - 01/11	1	4-hole aviation plug (Method 1)
   Wi-Fi Plug Pro - 04	2	2-pin green interface to RS-485 (Method 2)
   Wi-Fi Plug Pro - 02/10/16	3	RJ-45 crystal head
   Wi-Fi Plug Pro - 07	4	Serial port
   Wi-Fi Plug Pro - 03/05/06/08/12/13/14/15	4	Serial port

2. **Connect the Module**: Based on the identified interface code:
   • **For Interface Code 1 (Method 1)**: Connect the 4PIN power cable of the Wi-Fi Plug Pro to the inverter. Align the 4-hole aviation plug with the inverter and plug it in. Tighten the nut to secure it.
   • **For Interface Code 2 (Method 2)**: Connect the 2 PIN green interface of the Wi-Fi Plug Pro to the RS-485 terminal of the inverter, then connect the 5PIN power cable of the Wi-Fi Plug Pro to the inverter.
   • **For Interface Code 3 (RJ-45)**: Align the RJ-45 crystal head of the Wi-Fi Plug Pro with the inverter's port and insert it tightly. Fasten the Wi-Fi Plug Pro to the inverter with the screw.
   • **For Interface Code 4 (Serial Port)**: Align the serial port of the Wi-Fi Plug Pro with the inverter's port and plug it in tightly. Fasten the Wi-Fi Plug Pro to the inverter with the screw.
3. **Confirm LED Status**: After completing the connection, confirm the status of the LED light. When 4 LED lights remain continuously on, it indicates the module is in normal working status.
