FYI... Alvarion is shipping a DC power supply that supports all of the VL and 
BreezeNET B radios. The part number is 858554 and model number is the OPS-DC. 
It accepts 12-28VDC at 7A max and outputs 55VDC at 1A. It might help all of the 
brave souls that work off the grid.

Hi Mike. How are you?

Yes we do for VL, not BNETB. It is based on the BS-SH chassis. You would order 
a BS-PS-VL-48 and the appropriate chassis radios. I do not have a -48vdc 
stand-alone supply though. Just the one I mentioned earlier.

 We had a site that was on a 9500ft mountaintop that showed a 15mph 
 wind average (over the entire year). We put up two 400 watt turbines 
 and had 10 or 12 batteries (100ah). We only  had 5 radios total 
 (trango) and a small 5 port 12v switch. The site would stay up for 
 about 3-4 days before we had to go start the generator. I think our 
 total draw was under 80 watts for everything.

 You need to take a look at the Bergey wind turbines. They are 
 expensive, but they work really well. However, you can NOT mount them 
 on the top of a Rohn type tower... their mounting pipe has to be 
 exact, and if it's off by even 1/8, the whole thing will eventually 
 vibrate itself apart. Spend the extra $500 and buy their recommended 
 mounting tower system.

 We switched some hardware in the MikroTik routers mostly the newer low

 I wanted to get input from the WISPA list about a complete design for a
 off
 grid base station design base on a dual and quad radio system. We have
 been
 looking into this and have come up with a design using both wind and 
 solar
 power that will keep a unit up and running 24/7/365. The idea is to have 
 a
 complete package design so the base stations can be installed anywhere,
 but
 in order to keep the costs low it would be base on a max 48Watt design.

 Questions:
 1. Is this something WISP would want in the USA, and would find useful?
 2. Would you like this in a single package or parts (where a package 
 would
 have a 1 year warrantee and parts would not)
 3. What are you finding the power needs are at a typical WPOP?
 4. Other Comments?

 looking into this and have come up with a design using both wind and solar
 power that will keep a unit up and running 24/7/365. The idea is to have a
 complete package design so the base stations can be installed anywhere,
 but
 in order to keep the costs low it would be base on a max 48Watt design.

 Questions:
 1. Is this something WISP would want in the USA, and would find useful?
 2. Would you like this in a single package or parts (where a package would
 have a 1 year warrantee and parts would not)
 3. What are you finding the power needs are at a typical WPOP?

 We are installing a new tower very soon (in the next couple weeks) that
 will be run completely off Wind power with a 400-watt wind turbine. Of
 course we will have 6 105 amp hour batteries. Our draw at one of our
 popular sites is under 375 watts. This using a PC-Based MikroTik/ HP
 Procurve 2524, 6 Alvarion B NET Backhauls, 2 Alvarion VL-AU's, 1 Trango
 900 Sector.

 We switched some hardware in the MikroTik routers mostly the newer low
 powered AMD cpu's and that made a hugh difference and going from the HP
 procurve 2424m to a 2524 which cut the wattage from 90 watts to about 25
 watts. The Alvarion Units use about 200 watts total and the trango is like
 13 watts or so, (been a while since I checked them). The mikrotik router
 is uing 60-75 watts. All in all, not to shabby as far as power

Re: [WISPA] Off Grid System Design Comments.

2008-03-17 Thread Travis Johnson




I agree. Wind turbines really only produce about 50% of what they claim
(even at full wind speed). You will need 4 or 6 of that size wind
turbine to keep things running.

We had a site that was on a 9500ft mountaintop that showed a 15mph wind
average (over the entire year). We put up two 400 watt turbines and had
10 or 12 batteries (100ah). We only had 5 radios total (trango) and a
small 5 port 12v switch. The site would stay up for about 3-4 days
before we had to go start the generator. I think our total draw was
under 80 watts for everything.

You need to take a look at the Bergey wind turbines. They are
expensive, but they work really well. However, you can NOT mount them
on the top of a Rohn type tower... their mounting pipe has to be exact,
and if it's off by even 1/8", the whole thing will eventually vibrate
itself apart. Spend the extra $500 and buy their recommended mounting
tower system.

Re: [WISPA] Off Grid System Design Comments.

2008-03-17 Thread JohnnyO
If you're going to have 6 105AH batteries in parallell... you'll have 630AH 
available amps at 12V

If your wind generator is putting out it's maximum... Sounds like an Air 
X. You'll see a continous fluctuation from 225watts - 325watts maxium 
and it'll be all over the place ALL of the time.

Let's say your wind generator provides 300watts x 24 hours @ 12volts... 
You'll have from your wind generator ( 600AH) available for power.

Let's say your setup will use 350 watts x 24 hours @ 12 volts - Your 
equipment will need (700AH) in a 24 hour period.

This is only to say that everything is 100% efficient which never is, but 
you're automatically going to be short 100AH right off the bat... Not 
including days or hours your wind generator will be working at 20% capacity 
or it's internal safety shutting it down b/c of excessive winds.

You will need 1 wind generator... mounted about 20ft above the tree line 
 you will need to atleast triple your batteries and add either (1) more 
wind generator or (2) solar panels... My advice is to go with (2) solar 
panels and a very efficient charge controller.

Set it up for battery banks of 24 volts and power your equipment directly 
from the battery banks, don't use an inverter b/c you lose 15% right off the 
bat in the conversion.

Hope this helps.

Even at 100watts - you are seriously under-powered. Figure up how much power 
you need... and multiply that by a factor of 3.5 and you'll be safe and 
it'll be enjoyable to have a site off-grid.. Do it like you're planning 
and it's going to become a nitemare and the fuel you burn will have paid for 
the extra gear :)

Travis - the startup speed of these Air-X generators is around 10mph... that 
doesn't mean it starts generating power at 10mph - it just means it starts 
turning.

They did just release some consumer 1000watt wind generators that have a 
start-up speed around 7mph - they are much more efficient and their power curve 
is a LOT higher at lower RPMs.
