Yeah. Way fewer problems since I went to DC....I think it's about the
statistical probabilities of having one really nice power supply vs 10
cheap ones. 1/10th as many chances to fail.
It also takes up dramatically less space.
I have not seen that Alpha Cordex before, but it might be my new
favorite thing in the world.

Phoenix and Meanwell both make good AC to DC power supplies that have
battery managers available with low voltage disconnects. They also have
temp monitors to prevent over charging and dry contracts for alarm
states. You pick the battery size and the and size of the power supply
based on your load and how fast you want your batteries to recover.
Once we went to this setup or power problems practically disappeared.
Sure monitors tell you when per drops and if you know the battery size
you can calculate how long you have if Power drops before you have to
get a helmet or there if it doesn't come back.
Once we got all sites on this setup Mikrotik routers became out biggest
downtime issue. And they are decently reliable.

Give me a list of all the stuff you need to power, and I can tell you
how I'd do it... whether or not that's the best, or even a good way to
do it, is another matter. It is going to involve a pile of Packetflux
stuff though (of course most of that might already be there anyway...
)
That Alpha Cordex thing does look pretty nice, and would certainly
simplify things.

Any of you folks who know both dc plant and even more know small wisp

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.
