The Growatt ShineRFstick-X2 is the required communication dongle for establishing LoRa RF communication between a Growatt string inverter and a monitoring system like the ShineLink-X2 or GroHome Manager-X. This stick ensures a reliable, long-range wireless connection, which is essential for monitoring the inverter's performance.

The standard ShineLink-X2 monitoring package includes one ShineRFstick-X2, suitable for connecting a single inverter. To monitor additional inverters on the same ShineLink-X2 system, a separate ShineRFstick-X2 must be purchased for each extra inverter, up to a total maximum of 3 inverters.

By utilizing LoRa (Long Range) radio frequency, the ShineRFstick-X2 transmits all necessary data to the central monitoring device. This eliminates the need for a direct Wi-Fi or LAN cable connection at the inverter itself, simplifying installation and ensuring a stable connection even over greater distances.
