A clean, efficient setup using the XLTTYWL V3 POE injector and GL.iNet Beryl AX router, designed to reduce power consumption by bypassing the original Starlink router. This approach runs Starlink Gen 3 on native 12V DC, making it ideal for vans, RVs, and off-grid applications.
XLTTYWL V3 POE Injector
Input: 9โ36V DC
Output: 57V / 3A (Power over Ethernet for Dishy)
USB-C and USB-A ports for auxiliary devices
ESD and surge protection built-in
GL.iNet GL-MT3000 (Beryl AX) Wi-Fi 6 Router
Powered via USB (5V)
Supports VPN (OpenVPN, WireGuard)
Compact and lightweight โ perfect for mobile setups
Power Input:
Connect 12V DC to the injectorโs screw terminals
Observe correct polarity
Data & Network:
Plug Starlink Gen 3 Dishy into the injectorโs POE port
Connect the GL.iNet router to the LAN port
Power the router via the USB-C or USB-A 5V output on the injector
Dishy Configuration:
In the Starlink mobile app, enable Bypass Mode to disable the default Starlink router
Disable Snow Melt Mode (unless necessary in winter) to conserve energy
Eliminates the need for an AC inverter (less conversion loss)
Reduces idle power draw, especially overnight
Extends runtime on limited power sources (batteries, solar)
Custom router offers advanced control, VPN support, and better efficiency
Ensure proper airflow around the POE injector to avoid overheating
Use 8 AWG or thicker wire for 12V input to minimize voltage drop
Install the injector close to your DC distribution panel
If using solar, confirm capacity to support the ~30W draw of Starlink
The USB-A port on the XLTTYWL V3 POE Injector outputs 12V, not the standard 5V found on regular USB ports.
Do not use this port to charge phones, tablets, or other standard USB-powered devices โ this may cause permanent damage.
Only connect equipment explicitly rated for 12V input to this port.
