S1-W4G-ST data stick is a brand new one of a kind datalogger. This datalogger uses cellular technology to connect to Soliscloud. Not only does it have that, but you can also connect with WIFI. On top of that, the customer can use it as a WIFI stick during normal operations and when the WIFI goes down the datalogger will automatically switch to cellular. This will give you and your customers a seamless connection and a peace of mind. 
A data monitoring device that plugs externally into the bottom of the inverter. The logger relays information from the inverter to the Solis monitoring platform, SolisCloud. It can connect to a local router through Wi-Fi or to a 4G cellular network. If the Wi-Fi network goes down, the logger automatically switches to using the cellular network to limit the loss of data.
There are two versions of the logger, USB for S6 hybrid inverter models and 4-pin for all other Solis inverter models. 

NOTICE: This device is designed only for Solis brand inverters. It will not work with other brands or manufacturers.
