*Can only be used with: Starlink Flat High-Performance Kit with Wedge Mount


Summary

In this article you'll find instructions for how to convert your High Performance Starlink dish to run on DC power. Our high-performance POE injector enables you to convert your Starlink High Performance Dish to run on DC power only, eliminating the need for the Starlink Power Supply WITHOUT the need to cut your factory Starlink cable. However, you can elect to cut the cable to a custom length using the optional CAT-8 termination kit (available as an add-on option in the listing).  


Compatibility Disclaimer: This kit and these instructions only apply to the High Performance Starlink kit. Please reference the links at the bottom of this article for instructions on how to convert Starlink Standard Gen 3 and the Starlink Mini to DC. 



Before We Get Started, The Basics

What's Inside the Kit?

  • High Wattage POE Injector (accepts DC Input Voltage of 48-56v and outputs via POE at a max of 320W)
  • POE ethernet adapter (allows you to use the Starlink ethernet cable w/o cutting the cable)
  • Category 8 RJ45 Shielded 1FT Patch Cable
  • Wiring diagram

        Optional Accessories:

  • 12-36V DC to 48V DC Step Up Converter 
    • The POE injector only accepts DC input voltage of 48-56V, so this step-up converter will be required if your power source is below that range (this component will be required in most applications). 
  • Ethernet Cat 8 Termination Plug - Tool Free  
    • Add this if you want to shorten the length of your Starlink cable. Note: Doing this will require you to cut and re-terminate your Starlink cable, which will void the warranty on your cable. You'll find a diagram below with instructions on how to do this.
  • 6 Circuit DC Fuse Block
    • Can be used as a safety barrier (called a load center) to protect your electronics (and your RV). Properly fusing DC circuits protects your sensitive equipment from damage, avoids damage to wires and limits the risk of fire. All DC devices should be fused in accordance with manufacturer electrical power specifications. 


        Kit Requirements:


  • 48v-56v DC Power input. The unit will not function without either your own 48v DC power supply or the optional DC step up converter shown in the listing above. 
  • Input side of the Step-up up converter requires 30A (for Starlink HP only) fused Power Input at 12v or 15A (for Starlink HP only) fused Power Input at 24V. 
  • Requires properly sized gauge input/output wire which will vary based on voltage and distance, typically 8-10 gauge on 12-24v input with a fused home run from house battery is required (possibly larger wire for longer runs). *Consult an electrician for proper wiring sizing on DC power systems.



SAFETY TIP: As with all electrical installations, make sure to turn off all AC and DC power, properly wire and fuse your install & be safe!



Set up Instructions 


Option 1 (no cutting): 


  1. Connect a 48v-56v DC Power source to the power inputs on POE injector:
    • In most applications this will mean connecting it to our 12-36V DC to 48V DC Step Up Converter 
    • House battery ->Step up Converter->POE Injector
    • Recommended power cables: use fused 8–10 gauge marine grade duplex wire 
  2. Use the included 1ft RJ45 patch cable to connect the POE injector to the ethernet adapter. (Plug into the ports that say "POE" on the injector and "TO POE" on the adapter), like so:
  3. Next, connect the Starlink ethernet cable coming from your dish to the ethernet port on the ethernet adapter that says, "TO DISH." (above right)
  4. Finally, connect a standard Cat 5e (or higher) ethernet cable to the LAN port on the POE injector and to the WAN port on your Peplink router, and you're all set!




The High Performance Starlink kit comes stock standard with an 80 ft power cable. The diagram below will show you how to properly terminate the cable using our optional (tool free) Ethernet Cat 8 Termination Plug, so that you can shorten your cable. 


Note: Modifying your Starlink cable will void your warranty on the cable.



Now that you've modified your Starlink power cable you won't need the ethernet adapter that came with your kit. Plug the newly terminated cable into the port labeled "POE" on the POE injector. The rest of the configuration is the same as Option 1. 


DISCLAIMER: This product has been tested by MobileMustHave staff to be functional and reliable. If you elect to use the optional Starlink to ethernet kit you will have to modify your Starlink factory cable which will void the warranty of the cable and may void the warranty of your Starlink HP dish if installed improperly. The kit includes a termination end for tool-less termination however you still must carefully terminate the cable in the proper order for the disk to function. See wiring pinout diagram & instructional video located in photos of listing. We are not responsible for improper use or any damage as a result of using this product improperly. We cannot assist you if you cut your cable and your dish is nonfunctional as a result. We can ship you a replacement Starlink cable, if necessary, at a charge.
