Light Weight Wind Turbine Project - as I build it.

[sean_ork]

using bulbs in any dump load system is a very very bad idea - bulbs have a finite life

better to use a properly rated and proven dump using resistance wire etc ......

[sean_ork]

also, that charge controller is aimed at PV - PV controllers tends to simply disconnect the supply when float voltage is reached

a proper wind mill charge controller should divert the mill output to a dump when float voltage is reached

I have a number of these very fine controllers here for the smaller mills

The dump load controller is connected to the batteries only, it is not in the circuit from the turbine to the batteries at all, if you want a good cheap controller look up the Gurd controller here or on the another power site.
Coleman air also makes some very reliable charge controllers I used the kit for a long time, it's around 60 bucks all you have to do is mount it in a box and hook it up, it's adjustable for dump range and has three LEDs for battery state of charge and whether it's dumping and stuff. http://www.colemanair.us/vp_asp/scripts/shopdisplayproducts.asp?id=1&cat=Controllers%2FRegulators.
If that thing makes 13 volts at 80 rpms you can slap me in the ass and call me Sally.

Hmmmm,
£52 is equivalent to 81.1 United States dollars...
and postage to NC. USA is how much?

and the competition is OOOON!
GOD...I just LOVE Free Market Capitalism!

This one is also Looking GOOD! and it is only $60...
what is that button on it for?

I'm sure you could find that out all by yourself, took me 5 seconds

[fabricator]

What one are you talking about?

[Steadfast]

What one are you talking about?

Your Coleman air suggestion...

where can I find a DC light bulb?

[fabricator]

The red button is to manually dump or test the set point you have it at, all mobile equipment has DC light bulbs but you DO NOT WANT TO USE A LIGHT BULB AS A DUMP LOAD!!!!!
Go over to lowes and buy a cheap electric heater of some kind.

Steadfast;
Send GHURD a PM , he's one here as a GM too, BUT even better his dump load controller IS known WORLD wide and works!!
This can be verified by several people, he can also supply the resistors (if he has any left), I'm thinking can be done far less than some would charge in postage.
BTW: I have no less than 3 online at any one time.
you can look at his website by clicking on www.GHURD.info too :_)
He works nights so it may be a day or two before he responds, BUT I'll stand by his product!!

I must say you chaps have the patience of saints

[Steadfast]

I was thinking about buying Fabricator's "coleman air controller" and 2 or 3 of these.

2 OHM 100 WATT POWER RESISTOR DIVERSION DUMMY LOAD 12V
$10 each...

I was thinking I could rig up 2-3 of these rods in series and add a 100watt DC light into the series as well. that way I still get my grovey out door light...


BTW what tempiture will one of these 100 watt thingys get up too?
I dont want to burn down my shed...  How hot is 100watts?

We like helping people who are willing to learn and put up with being run through the wringer a time or two. AND in Steadfasts case 4 or 5 times.
Had he not shown the wherewithal we would've not gone this far a long time ago.

Thanks Bruce! 

Hey, this is not about only me...
This is about the other poor slobs, like me, who want to build a Turbine...

Here's the thing.
The dump controller MUST be able to handle (dump) as much of the output the windturbine is going to be able to output (Meaning PEAK output).
Thus it needs to be sized this way.
So let's say ChrisO's runs and is able to say output 13.5Vdc at 300watts max. You'll need to then build the dump load to handle the max amount without burning up or going open ans that would of course cause an unloaded turbine which is worse IMO than boiling a battery or two.

" The patience of saints" ROTFLMAO! Not as a general rule.

No worries.
PS> I sent Ghurd an email asking him to pop in here and do the numbers and let you know about HIM sizing one correctly. He normally does then numbers faster in his head while driving to work!!
WE know its more than just about you, we also know its more than just picking on the RED Alternator :_), there are some who are hoping he comes through and it works.
WE hate seeing US based companies go belly up unless they aren't willing to go the extra mile to get things understood.

Think toaster hot when in full dump mode!!

Did I mention you talk like David Niven? (Watched the "Guns of Navarone" last night)

[Mary B]

Light bulb is a bad idea. If it burns out your system could become unloaded.  You need around .4 ohm of load at 350 watts. 5 in parallel will get you to .4 ohms so that may be what you want but I don't know the exact specs of the wind turbine so it may be to small.

That you gotta give the guy, since this thread started two or three other newbies have stomped off in a huff, and I believe one was banned. LMAO.

[fabricator]

If you want an outdoor light, plug it into the inverter like everything else.

[sean_ork]

I find it very frustrating reading questions, such as DC light bulbs and bulbs for dump load - I do wonder if Steadfast ever reads anything other than the content of this thread - we call it spoon feeding here

no offence intended Steadfast, just an observation from someone with a little less patience 

[Steadfast]

I am looking at buying these:
Q-JD10140S Plusrite 3451 - 100 Watt - T4 - DC Bayonet Base - Halogen - Clear - 2,000 Life Hours - 1,200 Lumens - 120 Volt   $1.53 each X10

  SATCO-901560 DC Bayonet Socket with Mounting Bracket - 500 Watt - 125 Volt - 9 in. Leads - Satco 90-1560 $3.42 each - Just one

and combining it with 3 (or 5)of these:

wired in series and all mounted somehow on a concrete brick plate on the outside of my shed...

If I rig up 5 of these their tempiture will be spread out, right???
EI: hotter with only 3, cooler for 5???

[sean_ork]

having a bulb across a dump is a good way of knowing at a glance when the battery if full - having a bulb in series is a very bad idea

[Steadfast]

having a bulb across a dump is a good way of knowing at a glance when the battery if full

Yes, that is why I want to do it...
I can always wire the light in a seperate parrellel...  right?

do you know the difference between parallel and series wired ? - your previous post about putting a 100w DC light into the series is rather open to misinterpretation

you might also wish to confirm which mill you are proposing these parts are for

the toy one or the adults one - both will require a different setup

[Bruce S]

FAB;
ME TOO!!! First time I've ever been accused of being a SAINT!!

[Bruce S]

the toy one or the adults one - both will require a different setup

NOT really, if the one is setup for ChrisO's unit , then from my calcs, it'll certainly handle the RED Delco.
The other one I would not call a toy. A toy one would be one you would buy from Edmond Scientific to teach kiddes and isn't much more than something that would sit on a table.
Even if it doesn't work as planned, it's still not something I would consider a toy.
JMO.

If I rig up the dump for the Big one, it will be redundant over kill for the smaller one...
