Data logger Growatt Shine WiLAN-X2 by Growatt — WiFi connectivity for data logging

Growatt ShineWiLan-X2 is a data logger designed to connect Growatt inverters to the Growatt Cloud and enable remote monitoring and management of PV systems. The device supports Wi‑Fi, LAN and Bluetooth and transmits inverter data to the ShineServer (mqtt.growatt.com) so you can view real‑time and historical energy production, receive alerts and perform basic remote diagnostics via the ShinePhone app. It includes a USB Type‑A interface for communication with the inverter over Modbus RTU and built‑in memory that stores up to 30 days of data if the internet connection is interrupted.

Advantages

The Growatt ShineWiLan-X2 provides flexible connectivity: wireless Wi‑Fi with a USB stick (up to 50 m range), wired Ethernet (100 Mbps, up to 100 m over Cat5e) and Bluetooth (BLE) for local configuration and firmware updates. It offers continuous data transfer at five‑minute intervals, IP65 protection for outdoor installation, a wide operating temperature range (−30 °C to +65 °C) and low power consumption (2.5 W typical, 4 W max). The device supports standard wireless protocols (802.11 b/g/n) and is certified (CE, UKCA, SAA, RoHS).

Suitable for

• Residential solar PV systems
• Small commercial PV installations

How to use

Connect the ShineWiLan-X2 to the inverter via the USB Type‑A port and choose a network method: insert the supplied Wi‑Fi USB dongle to connect wirelessly (up to 50 m), or connect the device to a LAN cable for a wired link. Configure the device and perform firmware updates locally using Bluetooth and the ShinePhone app or set up remote access by linking the device to the ShineServer (mqtt.growatt.com). Once configured, the logger will upload data every five minutes and retain up to 30 days of records locally if the internet is lost.

Recommendations

For best reliability, use a wired LAN connection where possible and place the Wi‑Fi USB dongle within clear line of sight of the router to achieve the advertised range. Ensure the device is installed in a location protected from direct mechanical damage while still allowing ventilation, and follow local electrical installation regulations when connecting to the inverter.
