ØLAN connection
SolaX Pocket WiFi Dongle connects to a local network within 50 m of the installation to enable access to the SolaX Cloud monitoring platform.
If WiFi isn’t suitable, the Pocket LAN 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
SolaX Pocket 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)
