I've never actually set up a 12V site because there always seemed to end
up being other practical concerns, but I was always tempted by the idea
that if the power was out for a long time I could drive up and connect
jumper cables from my car and use the car as a standby generator. A car
can idle for a couple of days on a full tank of gas.

And unless you have 12 volt only loads, the cost is about the same for
a 24 volt site.

Our site was a backhaul, an rb750, and an Omni. We had tons of issues
with it until we upgraded to 24volt. Under load it would draw more
amperage and things would suffer. Had another similar site and it’s
issues went away after an upgrade to 24 volt.

Justin,
Our planned load for this site is only 70 watts for two backhauls, an
omni, and netonix. This should be well within range of the 155 watt
power supply, no? Our ethernet runs are also only 30 feet or less.
I also don't see that the voltage is adjustable on the AD-155 though?
Spec sheet doesn't mention it or have a picture of that.

Don’t skimp by going with the lower voltage. You will run into an
amperage issues pretty quickly. Seen a 12-13 volt site with 1
backhaul and an omni run into amperage issues within a week. Voltage
is fine, just way too much amperage. It’s not worth the headache.

Hello all,
We're looking to build our first DC power site for small MicroPops
and I see two options after reviewing the WISPA archives.
The first option would be the the SDR-240-24 and DR-UPS40 with Two
12v batteries powering a Netonix DC switch.
The second option we were looking at is just doing the AD-155A with
one 12v battery but I see the charging current is only 0.5 amps and
voltage is only 13.3V which is not an optimal float voltage.
My question is, to keep cost down, would we be OK going the AD-155A
route with the slightly lower float voltage with a 35ah battery?
We're ok with the battery taking longer to charge but I'm just most
worried if the 13.3V will wreck the battery or not.
Thanks all
