When it is not possible to monitor the inverter via the Internet, for example, you can apply this Growatt Shine GPRS-X. This is because it can communicate via the 2G network using a SIM card. You can buy your own (prepaid) SIM card from network providers such as KPN, T-mobile and Vodafone. Data consumption is estimated at 10MB per inverter per month.
The update interval is 5 minutes and Growatt offers a 1-year manufacturer’s warranty on the Growatt Shine GPRS-X module.
Especially for Growatt’s X series inverters, with a USB port.
