Re: [WISPA] Off Grid System Design Comments.
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.

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. Travis Microserv JohnnyO wrote: Cameron - unless you have CONSTANT wind, you are going to be seriously underpowered.

Re: [WISPA] Off Grid System Design Comments.
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. Travis Microserv JohnnyO wrote: Cameron - unless you have CONSTANT wind, you are going to be seriously underpowered.

Re: [WISPA] Off Grid System Design Comments.
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..

Re: [WISPA] Off Grid System Design Comments.
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. JohnnyO - Original Message - From: Travis Johnson To: WISPA General List Sent: Monday, March 17, 2008 8:21 PM Subject: Re: [WISPA] Off Grid System Design Comments. 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. Travis Microserv JohnnyO wrote: Cameron - unless you have CONSTANT wind, you are going to be seriously underpowered.

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.

All in all, not to shabby as far as power consumption. -Cameron 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.

Re: [WISPA] Off Grid System Design Comments.
This sounds like my first reaction when my boss told me we were going wind powerd (crazy). So, guessing from the orignal poster of the thread, many advise to go SOLAR!! Which I prefer anyhow. -Cameron 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.

Re: [WISPA] Off Grid System Design Comments.
Wind is a viable source of power Cam don't be swayed from your system deployment. Just deploy both at the same site and you'll get the best of both worlds.
