We have MT and Ubnt equipment of all shapes and sizes running at 27.6V. The only problems we've had are a handful of freak RB411s that won't power on with >27V. Most of the older ones wouldn't kick into overvoltage protection until >28V, but we've come across a few odd balls.

Charger isn't going to spit out 24v for batteries that need charged, it's usually 27v.

I was under the impression they would simply lock up and you could reboot, or maybe I'm just thinking of MT.

    Aha, thanks
    That explains why I have a dead NSM5 on my desk
    I guess the charge controller is not very good at giving out 24v
    regulated power

        Yes you will.  The batteries will probably be around 27v which
        Ubnt won't like.  You'll need to clean the ~18-27v from the
        batteries to 24v.

            Need help,
            I'm looking to deploy a UBNT NSM5 powered by a 24v solar
            supply.
            Does anyone have experience with this? The data sheet
            shows that it requires a 24v supply however the POE
            injector supplied is 15v, do I need a DC to DC converter?

            Best regards,
