I have heard that, but I have 100's of 411s all powered with PacWireless
24V POE.
We have 40 or more RB433 and RB433AH all powered with 24. The key here
is, at towers we us adjustable power supplies and adjust it while watch
the RB's reported voltage. We never exceed 24.5 volts and all seems well.
We use MeanWell AD-155B supplies or MeanWell DR-24-120 with Meanwell
UPS-40. Not DC to AC conversion so the batteries will run the equipment
much longer than a normal UPS.

Careful on powering most Mikrotiks with 24 volt. We have found, and
verified with roc-noc and some others, that many of the MT boards will
get hot with 24 volts to the DC jack and lockup and other weirdness.

Subject: [WISPA] Power for tower sites
Currently we are having some horrible issues with power at our
tower sites. Our current configuration is that we have tripplite
smart 500VA rackmout UPS connected to deep cycle marine battery.
This seems to work OK for a month or so and then kills either the
battery or the UPS or both. We then notice that the equipment at
the tower will power off (battery shuts down for about 10 min) and
then powers back on. This happens almost daily and in some cases
multiple times in a day. I think it may have to do with the
output volts of the battery not being high enough for the UPS to
operate. We are desperately looking for other alternatives to
what we are doing to resolve this issue. Most equipment will
operate at 12/24 volt. 1x Mikrotik, 2x Trango AP, 2x Trango
Link45, 4x UBNT Rocket. Any suggestions are appreciated.
