Monitoring Cloud is an application that can communicate with the inverter via WiFi/LAN/4G. It can realize alarm query, parameter
configuration, daily maintenance and other functions. This is a convenient maintenance platform.
Plug Dongle into “USB” port at the bottom of the inverter. After the DC side or AC side is powered on, the APP and inverter can be connected.
Please refer to the corresponding manual for details.

ØWiFi connection
ØLAN connection
WiFi dongle connects to a local network within 50 m of the installation to enable access to the Monitoring Cloud platform.
If WiFi isn’t suitable, the LAN dongle enables users to connect to the network via an ethernet cable. Ethernet allows for a much more stable
connection with less interference.
ØBasic setting and advanced setting
Ø4G connection
4G dongle allows you to use a 4G connection to monitor your system without the option of connecting to a local network. (This product is not
available in the UK)
