Iot Communication via 4G instead of wifi?

I recently got solar panels, the solar inverters are from SAJ, which are in the integration tab. To configure the solar inverters I need an ip-address, but the company who did the installation used eSolar 4g modules to show the electricity production in the eSAJ Home app. But for HA I need an ip-address and can’t find it for an 4g module.

Is there a way I can integrate information and sensors when they communicate via 4G instead of wifi?
