Re: [WISPA] DC UPS (and Solar?) Setup.

[Chris Ruschmann]

also, size your battery strings to be the same or larger than your load in
volts. down covering voltage uses less energy than up converting. so you
will lose efficiencies if you go that route.

example. running a 12 v battery bank using a netonix DC switch which will
up convert to 48v for the switch, then down covert to 24v for most gear
will yield you anywhere between 70-90% efficiency. thus making your battery
load that much less useful. Running a 48v bank will yield you 99-100%
efficiency. which will make sizing calculations easier for your run times.

Re: [WISPA] DC UPS (and Solar?) Setup.

[Chris Ruschmann]

if your interested in understanding the technology, then this site has a
lot of information on solar and DC in general. check out the faq's they are
worth the read.
http://www.solar-electric.com/learning-center

Air fibers use a lot of power in DC land. The biggest thing is
understanding your load. Buy according to that. I spent about a year on a
test site tinkering before I built my first production site. I have never
had an outage. and I've gone 22 straight days with absolutely no sun on
only batteries and no gensets. I'm in Alaska.

use 24v solar panels if you have space. try and do as large of strings as
possible. 48, 72, 96 Volts. We use midnight solar classic charge
controllers. They are rock solid and work great.

We use only AGM sealed batteries. My personal favorites are Full River.

Fused netonix DC switches.

Re: [WISPA] DC UPS (and Solar?) Setup.

[Paul Hendry]

Nice. How customisable is the charge/discharge side of this unit? Would 
be interested to see if they can be used with LiFePO4 cells. Also, 
roughly how much are these units?


Many thanks,

Re: [WISPA] FM Radio interference

[Sean Heskett]

i prefer liquidtight because the metal shield is protected by an outside
coating.  this keeps it both water tight and prevents it from becoming a
giant conductor should it happen to touch a live wire somehow.

you can buy it at any local electrical supply shop

Re: [WISPA] FM Radio interference

[Nick Bright]

I knocked up a quick shopping list at Home Depot, even including all the 
fittings it's not bad. The OD on 3/4" Flex EMT is a little more than 1", 
so around $200 plus the cost of hangars for a full 300ft of tower height.

While not cheap, it's not an overly expensive solution either.

[WISPA] DC UPS (and Solar?) Setup.

[Duncan Scott]

Hi,

So historically we've been a mostly AC setup, but I'm trying to figure 
out a DC setup for some of our smaller sites, and hopefully a solar 
setup as well. I'm new to all of this though so I'm trying to see if 
anyone has any written guides or part lists. Basic goal is to power an 
airfiber or equivalent and A few Canopy or Ubnt APs.

Here's what I've been looking at so far:

48v DC power supply
Traco TSP-BCMU360
Packetflux Site monitor 2 base
Packetflux SiteMonitor 6 Channel Switch Closure Input
Neotonix DC switch

This seems to work okay, the TSP-BCMU360 charges and monitors the 
battery and the Packetflux Sitemonitor provides a network connection to 
monitor the status.

Issues so far:

I'm running the site monitor off the BCMU, but this means that it's 
input power is 48v, I want to monitor the voltage of the battery, but 
that's just 12v and I don't think I can have different voltages plugged 
into the two inputs to the site monitor. Another option would be to have 
the site monitor powered off the batteries directly, but that seems bad...

Is the packetflux stuff the best solution for this, or is there another 
web enabling option? Seem pretty good so far, but I'm not even sure what 
the other options are.

The other issue is I have no idea what I should be using for 
breaker/fuses for the equipment. A suggested list of DIN mountable stuff 
I should have would be super useful if someone has it on hand. Also who 
to order this stuff from.

The other thing I would like to try is some kind of solar setup. Again 
it need to be monitored remotely. Power draw would be as low as I could 
manage. This is Oregon, so not lots of snow, but there are a lot of 
cloudy days. Packetflux makes several items that integrate with Morning 
Star controllers. It that a good way to go? Something like a TS-MPPT-30?

Batteries are another thing. I'm also very curious if Lithium ion 
batteries are feasible yet. This would need a different charger but it 
would save a TON of space and maybe even be cost effective given the 
smaller enclosure size that would be possible.

Then there is the issue of what solar panels to buy.

If anyone has any thoughts, comments, links, documents, etc. I'd really 
appreciate it.

Thanks,
Duncan

For anybody wondering, it looks like this type of armoring without 
pre-installed copper wires is referred to as "Flexible EMT" not MC.

There are both Aluminum and Steel products available

http://www.homedepot.com/p/AFC-Cable-Systems-3-4-in-x-100-ft-Flexible-Aluminum-Conduit-5603-30-AFC/204847343

http://www.homedepot.com/p/AFC-Cable-Systems-1-2-in-x-100-ft-Flexible-Steel-Conduit-5502-30-AFC/204847339

http://www.homedepot.com/p/AFC-Cable-Systems-3-8-in-x-100-ft-Flexible-Steel-Conduit-5501-30-AFC/205070919

3/4" should fit 4 or maybe 5 shielded cat5e cables. It looks like, from 
the specs, a single shireen 5e shielded cable would fit with about .2" 
extra room in the 3/8" version.

Shaun, what are your thoughts of liquid tight vs standard? Which do you 
use? Does anybody see any issues with capacitance changes in the 
shielding when it's wet, if not using liquid tight?

Do you know of a source to get MC without the copper pre-installed? What 
do you find is a good size for one cable? Do you use standard electrical 
junctions to consolidate them into a larger MC for the vertical run?

e.g. use a large (perhaps solid) conduit to get to the top, then break 
out to MC for each individual unit?

I'm interested in trying this strategy to compare it to ferrite chokes, 
which I have had good success with - when installed properly - but it is 
not a perfect solution, as sometimes link rates will still drop to 
10Mbps. I have to keep a script running on my routers to bounce the port 
if it drops to 10Mbps, which isn't very often.

Re: [WISPA] FM Radio interference

[Jim Patient]

Find out the exact frequency of the FM transmitter.  Be sure none of your cable 
lengths are a multiple of the frequency and end up as an antenna.   They can 
also cross a harmonic and pick up noise as well.  The radio engineer for the FM 
site can tell you what lengths NOT to make your cables.  A 12” difference in a 
cable length could make a world of difference in noise.

Not sure if this is the issue but I have had this issue before where one of the 
cables was acting as an antenna.

I have an existing tower that has a FM transmitter on it.  I believe they are 
just under 10,000 Watts.
Since we have been one that tower, I could never link up Ethernet that runs up 
the tower to the equipment on the bottom at 100BT.  I've tried ferrite rings on 
both ends, all cables are shielded and grounded.  Always had to go to 10BT to 
get a link.
I moved our radios 35 feet away from the bottom their antennas and still cannot 
link at 100BT.
The new radios require 1000BT too use them to full advantage.  Ideas?
I'm considering conduit all the way up the tower.  I don't want to put switches 
at the top.

I’ve used ferrite beads designed for the FM frequency in use and placed them at 
1/4 wave intervals on the ethernet (shielded). We haven’t had a problem since, 
but the run is fairly short.

That's probably the best solution, over using ferrites.

There is also the option of CAT5e with corrugated copper shielding, but 
MC conduit would be cheaper.

Re: [WISPA] FM Radio interference

[Nick Bright]

I've had similar experiences at FM sites. The basic issue is that many 
FM transmitters have a spurious spike about 1MHz wide right around 
32MHz. Since 100Mbps and 1000Mbps ethernet use a base frequency of 
32.5MHz, this is what causes your issue. If this spurious emission from 
the transmitter has enough power, it will drop your links to 10Mbps.


>I moved our radios 35 feet away from the bottom their antennas and 
still cannot link at 100BT.

I always try to be 30+ft away, so that should be a reasonable distance.

> I've tried ferrite rings on both ends, all cables are shielded and 
grounded.


We also use fully shielded and grounded cables. By this I mean Shireen 
with RF armor ends, and McCowan surge suppressors at the top, grounded 
to the tower frame. We don't use any other special grounding mechanisms 
(such as grounding the CAT5 shield using an LMR200 grounding kit - which 
I've had suggested before, but never tried).


What we have found to be a successful tactic is using Ferrites - 
however, it can't be just any ferrite, and it has to be installed in a 
specific way.


We use a FAIR-RITE Type 44 snap-on (TYpe 43 or Type 44 are acceptable):
http://www.kregercomponents.com/fair-rite-products/0444164281

The solid equivalent is 2643540002 but you'll have to recrimp your 
cables to use them. It does have higher impedance than the snap-on 
units, though, so there is a slight benefit.


You must fully weatherproof these, or freeze/thaw will break them off in 
one or two winters!


Next, you need to use enough of them. You must form a continuous line of 
ferrites *for at least 12 inches*. One single ferrite _is not 
sufficient_. We use TEN units on each end of the cable.


Next, you need to put them in the right place: The continuous line of 
ferrites must start _no further than 10cm from the termination point_ of 
the cable.


We have had repeatable success with this method at several FM sites. 
It's not perfect, as sometimes a link will still kick down every now and 
then, but it makes the problem a lot more tolerable. I suspect that more 
chokes would reduce the frequency of "every now and then".

Re: [WISPA] FM Radio interference

[Sean Heskett]

we have had good luck with shielded cable inside liquidtight conduit, but
even then sometimes it doesn't work.

fiber is the only way to truly "fix" the problem.

also we could that grounding the cables only at the bottom helped (instead
of at the top and bottom).

not being monitored, what else is that unit good for?  There is no LVD, no
temperature compensation, no charge voltage regulation, and no real way to
monitor the DC power supply (Is it even on) built into the unit.   There are
more expensive units out there with much of this functionality.In our
case we run without the UPS and monitor the power separately.  Maybe I'm
missing something?

DR-xxx-24 is not just a charger, it is a full power supply.  We used them
with and without the DR-UPS40.

SD and RSD have smaller footprint.

In non-DIN there is the AD-155B and if you find the right clips you can
mount that to a DIN rail but its pretty large.
