Starlink 12 volt POE, or not

[looknow12]

I am running a 12 volt Multiplus II 3000 for an RV and while the AC Load center is completely energized while boondocking. One thing I'm hoping to make more efficient is the Starlink Gen 2 I have running. Yaosheng makes a 48 volt POE Injector https://a.co/d/3PHH4iK and an adapter https://a.co/d/0ICizG9 that lets you bypass the modem and run everything off 48 volts. I also looked up a step up converter that get me from 12 volts to power the POE Injector. My question is will I save anything in efficiency? Or should I just let the Multiplus II invert. Currently my AC loads are 75 to 85 watts so any savings will be helpful as I'm only running 4 100ah BB batteries. Thank you

Did you ever get this up and running? I want to run dishy off a 48VDC bus bar (and have the power on/off controlled via a relay on my Cerbo GX). Just starting to research how to do this....

FYI I am doing this @AlaskanNoob. I'm using this POE injector: https://www.amazon.com/dp/B0CQC4321X. I have it hooked up directly to my 48V bus bar through a 4A DC breaker. My battery is set to absorb to 55.2V, which is below the POE maximum of 57V. It's been running for a couple weeks like this without any problems.

Appreciate it. I did the same using an Orion to make sure the power was set. It has been working great.

feeling brave ???? This guy shows how to ditch the 48v requirement altogether, it was a Ukranian starlink repair techie, who worked out that the 48v is only required due to cable length and bypassed the 48v requirement altogether ....

i like the mod, but not so sure about painting the board to protect it ......
