@JSchnee21 My conclusion after a bunch or research and experimentation is that there is no "perfect" way to install an EAP225 Outdoor with solar power only.
I have one installed powered by my "main" solar system, where I also have my cellular modem, (for backhaul) and one end of the aftermentioned CPE-210 link. At that end, I have 400 watts of solar panels, a 40 amp MPPT charge controller, and 270 amp hours of 12 volt LiFePO4 battery. I use all of that to power a small inverter, which in turn powers an 8 port PoE switch, which in turn powers all of the other devices (the CPE-210 through an active to passive PoE converter).
At the remote site where the other CPE-210 is, I have 100 watts of solar panels, a 10 amp MPPT charge controller, 24 amp hours of LiFePO4 battery (I am currently using 2 Talentcell AF120A1's), and I use a direct 12 volt to 24 volt passive PoE injector to power the CPE-210 (Tycon Power Systems TPDCDC-1224, available on Amazon) and a small inverter to power the factory injector for the EAP-225 (right now. I know that is inefficient, and I may change to another Tycon). All of the electronics and batteries are mounted in a BUD steel NEMA box.
But now that I have all of that working, thanks to you guys, I need to deploy another 5-6 EAP-225's. And I want the cleanest possible installation for each. I am using a nifty little 30 amp solar panel with built in MPPT charge controller to trickle charge batteries for other applications (like the pump on my diesel tank, and a gate opener), and I would love to use the same one for these AP installations. Coupled with the little 12 AH 12 volt LiFePO4 batteries that I am using elsewhere, and that same Tycon injector, I think I will be set. But if the thing really draws 10.5 amps continuous, then that little panel won't be enough to keep the batteries charged during a storm in the winter. Thus my question. I think they really draw more like 300 or 400 mA at 12 volts at least most of the time...
