3. System connection
Step1: Connect the WiFi transmission terminal to the controller, inverter, or
inverter/charger through the RJ45 port or the DB9 connector. Take the connection
diagram of the inverter/charger as an example as follows:
Note: EPEVER WiFi 2.4G RJ45 A is suitable for the controller, inverter, or
inverter/charger designed with an RJ45 port. EPEVER WiFi 2.4G DB9 B is ideal for
the device designed with a DB9 interface. For detailed connection cables, refer to
the connected device’s accessories list.
4. Operations
After successfully connecting the WiFi terminal to the controller, inverter, or

inverter/charger, the users remotely monitor the field devices through the PC, large
screen, or mobile phone.
Take the APP as an example to introduce remote monitoring through the mobile
phone.
Operation Steps:
Step1: Turn on the WiFi switch on the mobile phone, and connect to the local WiFi
network (2.4G WiFi network is a must).
Step8: On the APP home page, click the “EPEVER Cloud” icon to jump to the login
page. Input the user name and password, click the “Sign In” to enter the main
page. Users remotely monitor the field devices by a mobile phone. Note: Users
can also operate the remote monitoring by the cloud platform
(https://iot.epsolarpv.com/).
