I came up with a solution for this problem for now.
I use West Mountain Radio Rigrunners (
http://www.powerwerx.com/west-mountain-radio/rigrunner-4005.html ) to
distribute my voltage and protect my devices on solar installs. Makes
for a nice clean, easy-to maintain and troubleshoot install.
Fine business using the diodes to drop the voltage. Many silicon
diodes will show a higher voltage drop as the current
increases. Depending on the circuit you were measuring, one with
higher current would show a larger drop.
That is an innovative use of diode voltage drop.

Be careful using those diodes at sites where you're colocated with a
high powered transmitter. The diodes can do some weird stuff
(rectification, mixing) and could become a hidden source of
interference/noise.

Following up on this topic, I've received a couple suggestions for
dealing with this on existing equipment.
From Mikrotik Support:
You should do the following,
cut positive wire from the battery and add diode like this
good idea, but not too power efficient.

A couple issues:
Wasted energy - these converters can go as low as 75% efficient One more
point of failure Often the converters have their own low voltage
disconnect - I went 24v to give myself more battery headroom and time if
we have problems

I hear your frustration but I would not be yelling at MT. If I bought a
regulated power supply that didn't deliver the set voltage I would be
all over that manufacturer. Your RouterBoard worked to specification
and the power supply didn't. Who is at fault?Really surprises me

I use some Cincon Part EC4BW12, dc-dc convertors for anywhere I need to
power the sub 28v devices. It will take 18-72 v in and output 12 v. I've
had to install a lot of these as most of our sites were 48 v. When we
started replacing 532's with the 400 series, we had to put one in for

Looks nice. How do you connect to that? The spec sheet isn't clear,
just says it has pins on it.

Soldering iron. We just split the cat-5 appropriately, solder the wire
on and wrap them up in electrical tape with a Cat-5 jack on one end and
an RJ 45 on the other. This way we can just plug-em-in inside the
enclosure when we get to the top of the tower.

At Digikey or Mouser you should be able to find something similar but
switching type that has a higher efficiency and current rating. I've
used some modules for other voltages and they work great.
