@JaredBusch with a power conditioner?

I assume that @gjacobse is handling any DC conditioning needed.
I was wrong that it was 12vdc input though.
Here is mine at home.
@gjacobse you may want to looks for a 24v passive PoE injector with a DC input. The UBNT ones are all AC.
-
But wouldn't injectors require a ton of plugs to be laid out?

How so?
-
@MattSpeller Because each POE injector requires an outlet to power it and push the power inline to the cable.

That injector is 48VDC input. So, assuming he has 48VDC out of his solar array, he can simply make a standard center positive connector out of the solar array to the injector.

If you run solely on battery - you should not need a conditioner.
Thanks for the update on the TPLink.
Part of the 'ISSUE' is simple voltage.. The included adapter with the EnGenius is 12v. But the PoE injector is 48v. The UBNT uses 24v.
And while they are just multiples at less than 2AMPs,.. it's that differences and the cabling that makes it a pain.
The EnGenius has a coax power jack, the UBNT does not.

hanks for the update on the TP
I guess if you just need one phone its not a big deal I thought he was trying to lay out more though because he was discussing poe from a switch..

He is doing a point to point wireless bridge to a local access point for wifi if I understand the project correctly.

The 'Other' issue is that when I lay things out and check with a DVM, the UBNT supply is flat 24v, but when I put the Engenius PoE on,.. the voltage bounces... so it's one of those - triple check and use extreme caution and then check again..
This is the PoE 802.3af standard

al access point
Oh I was thinking the Engenius was the phone side of the house

No phone will be used. just a portable point to point network

The basic UBNT AP devices use the 24VDC passive PoE standard.
The Engenius probably uses 802.3af which is variable. -
Not finished yet. Need an enclosure for the AP, the cable and final assembly.
