We are doing this with our old CB3 and RB110 boards. I am actually
turning on the 2.4ghz AP mode, so that our techs can get online through
them without having to plug into the network. All of our APs are
switching to 10mhz channels and the laptops can't just hop on them anymore!

Tom, that $40 SBC should be a old CB3 from the junk pile. We now
call them "power pingers"

Its tough to find "Low cost" DC inverter equipment that supports
built-in IP.
Triplite makes an excellent line of Inverters, and they are
affordable. (come in 12v <mailto:1...@v>, 24V, and 48V), and can handle
high amerage charging and near unlimited load.
The problem is that these do NOT support IP type intelligence. There
is a physical port that can show some INverter detail, such as when
running on battery or not.
But this is a physical port that basically send voltage over one of
the pins to state the condition. It actually has a remote physical LED
block that can plug into that port.
IF someone took the time, they could make an adapter to connect that
port to a computers or SBC's serial or parallel port and write a small
program to read the pin voltage (on or off), and then use the SBC's
SNMP or something to enable the power state to be polled. ONe way to
get data on power outages is to plug a small $40 SBC bypassing the
Batteries directly to the AC, then if that device is no longer
pingable, you know no power is there.
Anyway, I use the Triplites now, but I as well, am looking for
something of similar spec quality that has IP built-in, to simplify
and improve remote monitoring.

With nearly all of our equipment being 24V DC, is anyone running
their sites off of batteries connected to an AC battery charger?
I'm envisioning something like a solar setup, but instead of using
solar panels to charge the batteries, you use an AC-powered
battery charger. This would eliminate the AC to DC to AC to DC
conversion that a typical UPS setup would introduce, making the
efficiency far better and the run-times far longer. I'm thinking
I would like to do this (I need to revamp our UPSes everywhere
anyway) but am not sure of what pieces and parts I need or if this
is a terrible idea that I should run away from.

I second this. We had been using Belkin consumer UPS' because of their
physical dimensions, but we've been changing them out for APC 750
and 1500s
with SNMP where ever we reasonably can. Get ours new through
Ingram Micro.
