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: 1. Monitor temp in the cabinet 2. Monitor/alert on loss of AC line power through TP DIN 3. Monitor voltage of the batteries 4. Monitor voltage to the Netonix 5. Monitor Current to the Netonix 6. Monitor Current in/out of the batteries 7. Auto start the heater below 40 degrees 8. Auto start the fan above 80 degrees 9. Power cycle the netonix from the TP DIN 10. Power 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.

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.

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.
