There's a lot to like about that setup. The DR-UPS can do 40amp on 24v,
so your upper limit is almost 1kW. Just drive it with a bigger 24v
supply as needed.
What has held me back from that in the past is the DR-UPS is not
available in 48v, and the biggest power consumers I have are 48V. I
went to Traco to stay 48V. OTOH your rig is so much cheaper than Traco
that adding an RSD-300B-48 for another $100 is not a bad deal.

Here is what we are doing, I think this is close to what Steve is
asking for:
Meanwell SDR-240-24 AC to DC power source: $84
Meanwell DR-UPS40 Battery Float/UPS: $37
Tycon TPDIN MonitorWeb2: $131
24 V of battery backup $70-120 depending on the runtime looking for
Netonix 150 W or 250 DC switch: $250-350 (This is really the only
expensive component)
Heater: $65
Fan: $14
With this, we can run 5-8 hours on very small batteries, we figure we
have several hours to get a generator to the site if power isn’t coming
back. We run all POE from the Netonix, it works really well. Here
are the other things we can do with the box:
Monitor temp in the cabinetMonitor/alert on loss of AC line power
through TP DINMonitor voltage of the batteriesMonitor voltage to the
NetonixMonitor Current to the NetonixMonitor Current in/out of the
batteriesAuto start the heater below 40 degreesAuto start the fan above
80 degreesPower cycle the netonix from the TP DINPower cycle any AP,
Router, Backhaul from the Netonix
We also put a Mikrotik router in this cabinet. Usually a Hex POE (for
small sites) or a 3011 for larger sites.
We have 13 in the field set up like this and are going 15 more right
now. While it might be a little more than what you were thinking, it
gives us a ton of control for pretty minimal investment per site.
Best part is, no coding necessary. Doing all this with the Monitor
Web2 settings and/or SNMP. Let me know if you are interested in
pictures. For this second batch we have started using Terminal blocks
to clean up the wiring, the cabinets look a little better, but we went
to a smaller poly cabinet that makes things a little tight.

You can still do DC-DC off it and then hook up netonix. If I had to do
it now I'd go with the IDC switch. When we did our design, the idc
didn't exist so we just went down to 24V off of our A and B sides and
run a redundant powered 24V bus which all the netonix switches run on.
I better buy up another batch of Elteks before all y'all buy them all
up. These are mostly decommissioned Sprint/Clearwire btw.

Which Netonix are you running at - 48V? Or are you using an isolated
DC/DC converter in between the -48V rectifier and Netonix?

Any of you folks who know both dc plant and even more know small
wisp budget interested in looking at our gear and power setup and
giving realistic advice that doesnt have a 10 different 500 dollar
components combined with a full time linux guy and a full time
coder?
Id love you to do it out of the kindness of your heart, but i do
have some advisory busget.
Im just tired of the apc ups waste and super ghetto runtimes on
batteries coupled with having to accept we are destroying runtimes
by letting the apcs die..... please, somebody, please. Otherwise i
have to go to the facebook groups, and thats like going to a
mikrotik or ubnt forum.
