Growatt LAN Interface Shine LAN‑X NV820320 Ethernet connectivity module for inverter communication

Growatt LAN Interface Shine LAN‑X (NV820320) is an Ethernet connectivity module that provides wired communication between compatible Growatt X‑series on‑grid inverters and the Growatt cloud server. The device uses a USB Type‑A dongle connected to the inverter and an RJ45 network cable to the router to establish automatic data transfer. Built‑in memory stores inverter data for approximately 30–40 days if the internet connection is interrupted. The module supports monitoring of inverter operation and energy output and can help detect or troubleshoot PV system failures remotely.

Advantages

The LAN interface delivers a stable wired connection for reliable data transmission and remote monitoring. It features low power consumption (max. 3 W), IP65 protection for outdoor installation, and compact dimensions (152 × 47 × 28 mm). Built‑in memory preserves historical data for up to 30–40 days during network outages, and the unit is certified to CE and RoHS standards.

Suitable for

• Growatt X‑series on‑grid inverters with external power supply
• Residential and small commercial PV systems requiring stable wired monitoring
• Installations where LAN cabling is preferred over wireless communication

Key specifications

• Network: LAN (Ethernet)
• Data rate: 10 Mbps
• Voltage: 5 V
• Max. power consumption: 3 W
• Interface: USB Type‑A (to inverter)
• Supported server: ShineServer (server-cn.growatt.com)
• Data transmission interval: 5 min
• Operating temperature: -30 °C to +60 °C
• Protection class: IP65
• Dimensions: 152 × 47 × 28 mm
• Weight: 84 g
• Certifications: CE, RoHS

How to use

Connect the USB Type‑A dongle to the Growatt inverter and run an Ethernet cable from the module to the local router. Once powered and networked, the interface will automatically establish a connection with the ShineServer (server‑cn.growatt.com) and begin transmitting data at five‑minute intervals. If internet access is interrupted, the module will continue to log inverter data locally for about 30–40 days and upload it when the connection is restored.

Usage recommendations

Install the LAN cable in a dry, protected routing path and ensure the module is mounted where the IP65 rating prevents direct water ingress. Use a stable local network and verify router settings or firewall rules allow outbound connections to server‑cn.growatt.com for uninterrupted monitoring.
