Quick Guide

The EPEVER WiFi 2.4G RJ45 D adapter allows you to transmit operational data from EPEVER solar controllers, inverters, or inverter/chargers to the EPEVER cloud server or local mobile app. It supports a communication distance of up to 20 meters and is powered directly by the communication port.

Appearance and LED Indicators

The adapter features an RJ45 connector and an LED indicator to show the connection status:

Green flashing fast (1s on, 1s off): Powered on, no device connected to hotspot, network not configured.
Solid green: Connected to router (remote mode) or connected to APP (local mode).
Green flashing fast (100ms): Connected to device.
Green flashing slowly (1s on, 3s off): Connected to server (remote monitoring mode).

System Connection

Connect the WiFi adapter directly to the RJ45 communication port of your controller or inverter. If your device does not have an RJ45 port, a supporting communication cable or adapter is required. Warning: The working voltage is 4.5V–5.5V. Exceeding this range may damage the adapter.

App Operation

The adapter works exclusively with the Solar Guardian app. You can monitor devices and set parameters via the app or the PC platform (https://gl.mysolarguardian.com/).
