So my off grid place in WNC I'm designing a small system for getting internet to the house which currently barely has 1 bar of Verizon signal. 500ft from the house we have a hilltop that gets full signal LTE from Visible(Verizon). Using Visible's lower tier service I get 20-30Mbps download and 20Mbps upload speeds. My plan is to get a used Google Pixel (probably a 6) and USB tether it to a GL iNet Beryl AX (GL-MT3000) travel router. Then use a directional Wifi AP to jump the 500ft down to the house and pick it up and rebroadcast inside the house as well as provide some wired ethernet inside the house. Sounds complicated but I've worked in IT for 20yrs+ so it's my bread and butter
.
My final snag is battery/solar choice. I'm not using an inverter, I'm staying DC with some step down converters to power 2 USB ports (one for the router, one for the wireless charger for the Android phone). The Wifi AP is 24V POE with a small POE injector that comes with it. If I run 24V setup I can power that directly or if 12V I would just need to convert from 12V to 24V for that one device. The router uses <8Watts, Wifi AP at 24V/0.5A (12watts?) and then the cell phone probably another 15watts. Total power draw maybe 40watts... Would ideally like enough battery to power the setup for 48hrs due to the often cloudy periods we experience in the mountains at 3,500ft halfway up a 6,200ft. Nice sunny summer days will even have 5-6 10min rain showers frequently. Temps usually no higher than low to mid 80s in summer, most often high 70s, lows in the winter generally only a few days a winter are below zero.
I'm thinking AGM is probably going to be the route to go given the cold temps in the winter. It will be in a weather proof box, with the travel router, POE injector, and batteries with solar panels nearby. Has anyone else done something similar? Oversizing the solar will help recovery happen quicker in the periods of sun. I have seen some small solar panel kits with midnight solar charge controller that may work.
