EPEVER WiFi Transmission Terminal

1. Overview

The WiFi transmission terminal is specially designed for EPEVER solar controllers, inverters, or inverter/chargers. It automatically uploads data to a cloud server using wireless transmission technology after connecting to a local wireless network. This allows devices connected to the terminal to be remotely monitored through the cloud server or a mobile APP, making communication and data transmission easier and more convenient.

Features:

• Wireless monitoring of solar controllers, inverters, or inverter/chargers.
• Support for cloud server or APP communication.
• Convenient connection and operation.
• Adopts a high-performance M4 core CPU.
• Ultra-low power consumption and high-speed data processing capabilities.
• Directly powered by the communication port.
• Up to 50 meters communication distance.
• Supports both AP (Access Point) and STA (Station) working modes.
• One-key to restore factory settings.

3. Working Procedures

Step 1: Connect the WiFi transmission terminal to the controller, inverter, or inverter/charger through the RJ45 port or the DB9 connector.

Step 2: Users remotely monitor the controller, inverter, or inverter/charger through a PC, large screen, or mobile phone APP.

A diagram illustrates a solar power system. It shows a PV array connected via circuit breakers to a battery and a solar controller. The solar controller is connected to an inverter. Two EPEVER WiFi transmission terminals are depicted: one with an RJ45 connector connected to the controller/inverter, and another with a DB9 connector also connected to the controller/inverter. These WiFi terminals enable remote monitoring via a PC, large screen, or mobile phone APP, connecting through the internet or cloud.

STA Mode (Station Mode)

When there is a local network, the WiFi terminal uploads data to the cloud server automatically.

Operations:

1. Connect your phone to the local network.
2. Open the EPEVER Cloud APP and click the "EPEVER Cloud" icon to enter the login interface.
3. Click the "Wifi On Cloud" icon to enter the "Network Connection" interface.
4. Connect to the network by searching for available hotspots or scanning the QR code on the WiFi terminal. After a successful network connection, the WiFi terminal is added to the cloud server automatically.
5. Click the "Confirm" button to return to the initial login interface.
6. Input your username and password, then click the "Sign In" button to enter the cloud interface. All devices added to the cloud server can be monitored by the phone APP.

AP Mode (Access Point Mode - Default)

When there is no local network, the WiFi terminal cannot upload data to the cloud server. All operations (including real-time monitoring and parameter settings) are carried out directly between the mobile phone and the WiFi terminal.

Operations:

1. Turn on the WiFi switch on your phone and open the EPEVER cloud APP.
2. Click the "Local" icon to enter the "WiFi" tab.
3. Click the corresponding WiFi name to connect to the WiFi terminal. Users can obtain the name by checking the QR code on the WiFi terminal.
4. Enter the real monitoring interface after successfully connecting to the network (only downloaded product models can be monitored).

The phone APP supports both AP (default) and STA working modes. According to the login method and local network conditions, it automatically enters the corresponding working mode, eliminating the need to manually switch modes.
