I could live with either AC or 48V, but 48V would be convenient.
I'm looking at the Ubiquiti EdgePoint EP-S16. It takes a 54V DC input,
has SFP+ uplink ports and twelve 802.3af/at ports. I don't actually
expect to use every port, but in theory you could load that up to over
300W, and if I make sure to size the UPS for the switch then it's more
idiot proof when people come along and add stuff.
Ubiquiti has a 54V UPS module now, and you can put in 2+0 150W power
supplies for 300W total, but it's an indoor case and operating temp only
down to 0c. By the time I put that in a heated outdoor box it doesn't
look too attractive anymore.
I'm very familiar with the Traco and similar products. It would just be
hard to beat $650 for a complete system using modular DIN components in
a box. There's also something to be said for the simplicity of one part
on the BOM.
Of course I could use the smaller EdgePoint, but then I don't have the
10Gig uplink.
I'm checking with Cyberpower on what happens in an overload
condition...maybe the guy who adds one AP too many will realize his
mistake very quickly.

You are looking at 48VDC output, or AC with a 48V battery string?
Note that unit seems to have around 700 watt hours of batteries, not
bad, but if you are running 300W or 600W of loads, it’s not going to
give you much runtime without adding more batteries.
We have a couple Alpha Micro350 systems at some small sites, which
looks physically similar, but that’s AC output. We only use them at
small sites because it’s not enough batteries for a large site.
Normally we would put a Traco TSP BCM48 and a TSP360-148 or TSP600-148
in the same enclosure with our other DIN rail equipment and maybe a
bunch of 100 Ah batteries in a separate battery box. Or maybe 4 x 22
Ah batteries in the same enclosure, if we don’t need a lot of runtime.

I tripped over this guy the other day. They're $650-700
retail and
frankly, that's really not a bad price for a one-and-done
48V outdoor
power system.

....but 150W is pretty small. I wish there was a 300W or
600W option.
Why does it seem like every product I want is a white
whale and that
every vendor has something that's like 90% of the way
there, but not
quite perfect?
