How to Install and Activate the GO Cellular Kit (US version) – Tigo Help Center

The GO Cellular Kit adapter allows the Tigo EI Inverters to connect to cellular networks. The kit includes a 5-year prepaid plan.

The Tigo EI System's communication priority is always WiFi, but if that is unavailable, the system will automatically switch to cellular.
