Thanks Greg,
I can see how putting load on just one part of the battery bank could cause
issues but this load is quite small compared to the total battery capacity.
I will be putting only 8w on two 150Ah 12v batteries (3600Wh total
capacity). It would take 400 hours to deplete the battery bank with this
load only, do you still think this will be a problem? If this will be a
problem I could have the load moved from one bank to the other at a
scheduled maintenance visit say twice a year. I really appreciate the
advice.

Where did you put that diode? I have done this and at the low power
that is needed they do not get noticeably warm at all.

I tried that method.  Diode got hotter than hell.  Burnt right through the
insulation I covered it with (and since it was bent the jacket came right
off).

Re: [WISPA] Another Ubiquity question

[Jeromie Reeves]

Why not run the NSM5 on 24v? Just add a diode or two to the + side,
the 1v drop on them will protect the NSM from
the charge voltage of the bank. $2 fix

Re: [WISPA] Another Ubiquity question

[Greg Ihnen]

I have a PS2 wired to the 12 starting battery of a generator which starts
and stops a few times a day with no issues. The PS2 doesn't even reset when
the gen starts and the battery pulls down to around 8~9 volts while the
starter is cranking. When the gen runs the batt voltage goes to ~14.6.

Re: [WISPA] Another Ubiquity question

[Greg Ihnen]

My two cents: If you discharge part of your battery bank unevenly (pull off
just half of your 24v bank to get 12v for some loads) you will have trouble
with part of the bank getting over charged and part of the bank not getting
charged enough. If you were charging the bank with an AC charger that
charges each battery individually according to it's needs that wouldn't be
a problem. But if you're charging the entire bank with a single device that
charges the entire string in series like a 24v solar charger that is not a
good way to go. You'd be better off with a 24v to 12v regulator.

 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?

Re: [WISPA] Another Ubiquity question

[Eric Roth]

I have done this at home with a Pico M2HP. My setup has two 60w 12v solar
panels connected to a charge controller with 2 12v 55AH AGM batteries in
parallel. The Pico is connected to the load output of the charge
controller with a DC input POE injector that I bought from Amazon for
about $10.

 

The setup works pretty good and I've had my first true test of the battery
bank this past month. Its rained here every day for the last three weeks.

~12v should be OK by specs, but I've never heard of anyone doing such a
"low" voltage to a Ubnt device.  Not sure if no ones tried it or it just
ended quickly in failure.

 

Just be aware that 24v and 12v batteries have a higher voltage for
charging.

I only have the one NSM5 to connect, I could hook this up to the parallel
segment of my battery bank and get only 12v while the rest of the
installation that's connected in series gets 24v. Do you think this will
work? Don't really have to worry about the NSM5 running down the battery
cause load is low and the cable run is under 10m so the voltage drop from
12v will be negligible

 

So this is how it would be:

24v solar panel connected to 24v charge controller with 4 x 12v batteries
connected in a 2x2 series/parallel array. cable connected to the parallel
segment of battery bank (theoretically giving 12v to the NSM5), rest of
the load connected to the charge controller at 24v

 

What do you think?

I've had installations like this. Its best to move the radio periodically if
