Starlink Prewire Solutions for RV, Marine & Fleet
Starlink Solutions for RV, Marine & Fleet
Purpose-built DC-DC converters and Power over Ethernet systems that eliminate inverters, simplify factory wiring, and deliver reliable Starlink connectivity from the production line forward.
Why Standard Starlink Installs Fail in Production
Running Starlink off an AC inverter creates cost, complexity, and failure points that don't belong in a factory environment.
Voltage Drop & Resets
AC inverters introduce voltage instability, causing Starlink units to cycle, drop connections, and deliver unreliable service to end users.
Messy Dual Cable Runs
Separate power and data cables mean more labor, more routing, more failure points, and a higher error rate on the production line.
Exposed Exterior Wiring
DC wiring running outside creates safety risks, cosmetic issues, and warranty concerns that reflect poorly on the OEM brand.
A Complete Prewire in Two Components
The DC-DC converter and POE injector work together to create a clean, single-cable Starlink installation that's repeatable at production scale.
DC-DC step-up converter (left) feeds the POE injector (right). Single Cat6 cable carries power + data to dish.
12V Battery Connects to DC-DC Converter
The vehicle's 12V DC system feeds the step-up converter, which outputs regulated 48V (Mini) or 57V (Standard). No AC inverter — pure DC efficiency.
Converter Powers the POE Injector
The DC-DC output feeds the POE injector, which combines stepped-up power with the data signal onto a single Cat6 Ethernet cable.
Single Cat6 Cable to Starlink Dish
One Cat6 cable carries both power and data to the roof-mounted Starlink Mini. One sealed roof penetration instead of two.
Data Returns for Internal Distribution
The POE injector splits the return data signal, allowing OEMs to hardwire directly into the RV's internal network or Wi-Fi router.
Stop Bolting Your Internet to the Roof
Roof-mounted Starlink means you're stuck with whatever obstructions are overhead — trees, awnings, other rigs. A POE outlet on the exterior of your vehicle changes everything.
The Old Way: Fixed Roof Mount
- ✗Dish is stuck on the roof — blocked by trees, awnings, and neighboring rigs
- ✗Need to run an AC extension cord or inverter to power the dish outside
- ✗Can't move the dish to find a clear view of the sky
- ✗Wi-Fi only — no hardwired connection inside the vehicle
The CT Way: Exterior POE Port
- ✓Plug a single Cat6 cable into the exterior POE port — it carries power AND data
- ✓Walk the Starlink Mini to an open field for an unobstructed 360° sky view
- ✓No AC power needed outside — no extension cords, no inverter, no generator
- ✓Hardwired Gigabit Ethernet inside + Wi-Fi distribution from your own router
Grab & Go Portable
Drop the Starlink Mini into a Conversions Tech protective case. Walk it to the clearest spot at camp. Plug in one Cat6 cable. Done — internet in 60 seconds, no tools, no setup.
One Cable Does It All
The Cat6 cable from the POE port carries 48V power to the dish AND returns Gigabit data to your vehicle. No separate power cable. No AC. No mess. Just one weatherproof connection.
Unobstructed Signal
Trees, awnings, neighboring rigs — none of it matters when you can place the dish in an open clearing. Get the full 360° sky view that Starlink was designed for, every single time.
Why this crushes Winegard's approach:
Winegard locks you into a permanent roof mount — fixed position, fixed obstructions, fixed limitations. Conversions Tech gives you both options: a clean permanent install for travel, AND a portable setup you can deploy anywhere in under a minute. Winegard can't do that.
Engineered for Production-Line Integration
Two components, one system. Combine the DC-DC converter with POE for a complete factory-ready Starlink prewire.
DC 12V to 48V Step-Up Converter
EP-SK0113
Converts standard 12V battery power into regulated 48V DC for Starlink Mini (or 57V for Standard), eliminating the AC inverter entirely. IP68-sealed for permanent installation in harsh environments.
- Regulated output eliminates voltage drop, resets, and instability
- IP68-rated — sealed against vibration, moisture, and dust
- 144W continuous with OCP/OVP/OTP/SCP protections
- 96% conversion efficiency — runs cool, extends battery life
5-in-1 GigE POE Injector + Splitter
EP-SK0091
All-in-one step-up converter, POE injector, and splitter in a single sealed enclosure. Accepts 12V DC, boosts to 48V, and injects power onto a Gigabit Ethernet line. One cable carries everything.
- Single Cat6 carries power to Starlink and data back
- Eliminates exposed DC wiring on the vehicle exterior
- 150W output with full 10/100/1000 Mbps Gigabit passthrough
- Integrated splitter at dish end — zero extra adapters
What This Saves on the Production Line
Every unit that rolls off your line with a proper DC prewire saves money, reduces callbacks, and increases the perceived value of the build.
Battery Savings Per Unit
Running Starlink through an AC inverter wastes 120–480Wh per day as heat. DC-to-DC conversion eliminates the inverter entirely — that's the equivalent of a full solar panel's daily output recovered.
Fewer Cable Penetrations
POE means one sealed hole through the roof instead of two. Less sealant, less labor, less chance of leaks. On a 1,000-unit production run, that's 1,000 fewer potential warranty claims from water intrusion.
Saved Per Install
A single Cat6 run replaces separate power + data cables. Fewer steps, fewer connectors, fewer opportunities for error on the line. More repeatable = lower training cost for new techs.
