Sungrow has developed various communication solutions for different scenarios. The
4G communication module (EyeM4A dongle) can be used when there is no WiFi
available or to bypass the firewall settings. This document is intended to provide users
with detailed information on the 4G communication module.
1. Basic Information of the SIM Card
The 4G communication module comes with a prepaid SIM card. The basic information
of the SIM card is shown in the table.
SIM card type
Network provider
4G data plan
Duration
Start date
Due to the limited data plan, it is recommended to install no more than three (3)
inverters for normal monitoring and firmware update purpose. If there are more than
three (3) inverters installed, the customer might need a new SIM card with bigger data
plan (at least 10MB per inverter per month) or purchase a 4G modem.
If the site is out of the coverage of Vodafone/Optus network, the 4G
communication module cannot be connected to iSolarCloud Server. The
customer might need a SIM card from different telecom operator (e.g. Telstra) which
covers the area.
For any instance that the SIM card provided with the 4G communication module cannot
be used, and customer needs to change to a different SIM card, please contact
Sungrow for support.
