Starlink Gen 3 – 12V Direct Integration

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.

Components Used

XLTTYWL V3 POE Injector

• Input: 9–36V DC

• Output: 57V / 3A (Power over Ethernet for Dishy)

• USB-C and USB-A ports for auxiliary devices

• ESD and surge protection built-in

🛑 STOP The USB-A port on the XLTTYWL V3 POE Injector outputs 12V, not the standard 5V found on regular USB ports.

GL.iNet GL-MT3000 (Beryl AX) Wi-Fi 6 Router

• Powered via USB (5V)

• Supports VPN (OpenVPN, WireGuard)

• Compact and lightweight – perfect for mobile setups

Connection Overview

Power Input:

• Connect 12V DC to the injector’s screw terminals

• Observe correct polarity

Data & Network:

• Plug Starlink Gen 3 Dishy into the injector’s 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

Why This Setup Matters

• 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

Tips for Installation

• 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

🛑 STOP – Critical Safety Warning

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 — this may cause permanent damage.

Only connect equipment explicitly rated for 12V input to this port.
