Hi all,

I am about to wire up my new Morningstar TS60 to my 2 heavy duty 12 Volt tractor batteries that's two in series to give 24Volts . I need to set it for Diversion Charge Control.

Now these DIP switches are confusing.

Dip switch 1 ON to get the unit working.

Dip switch 2 ON to set for 24 Volt systems.

Dip switch 3 OFF that's for 48 Volt systems.

Dip switch 4?

Dip switch 5?

Dip switch 6?

Dip switch 7 ON for Diversion Control,

Dipswitch 8 OFF (I can use the pushbutton) it depends on settings for 4, 5, 6

So if anyone can advise or help with 4, 5, 6 it would be a great help indeed.

Paddy.

Hi Paddy tractor batteries or not suitable they are just not designed for re systems,they just won't last.

The controller dumps power from the battery at a voltage set by you useing dip switches4, 5, and 6,

A suitable set point would be 4 on 5 off 6 off for a 24v system this = 28.8

yes this is the system I emailed you about

I cant see how there could be a problem related to drinking water

I will post a picture if anyone is interested

Hi Michael,

Just got in ... Thanks for that I'm learning, I'll be back to you for more.

What type batteries should I go for?

Hope you stay in touch.

Could someone post a link to show the best type batteries for small wind turbines?

Hi Michael.

Looking forward to your pictures of your resistor dump. We just erected the tower today with the turbine atop. Have the Ts60 controller, 3000w inverter is on order. I see tractor batteries are not the best so I'm looking out for what's best., I have nine 24v 100w bulbs Got them handy! To put in parallel for the dump load for now until I can build an apparatus like yours.

Paddy.

Thanks.

That's a good link with plenty of information about batteries, I bookmarked it. But it doesn't actually say which type is best for wind turbines .

hi paddy,

rolls batteries are definatly the best. but they are also the most expensive. a lot depends on how you intent to use the system. if it is going to be your only supply for a number of years go for the rolls batteries. 6 of the s460 6 volt ones will give you 800 amp hours at 24 volts and will cost you around 2 grand,but given they will last 10 years or longer that works out at around 4 pounds a week. if you have a grid supply and just want to supplement it you could try something cheaper. i managed on 6 110 amp hour 12 volt leisure batteries for 5 years before they died. worked out around 650 uk pounds for 5 years, but i only draw a small amount around 200 watts per day fed by a 8 foot wind turbine. i am near the coast so get lots of wind. if you are planning to use all of that 3 kw inverter on just wind you will be getting though the cycles pretty fast. a lot depends on how you intend to keep the batteries charged. look at the surrette web site for lots of info on there batteries. a cheaper alternative is fork lift truck batteries if you can, A find them,and B have some way of moving them. i rejected this option because although i could get them loaded onto my van i had no way of getting them off again bar hiring a local farmer to do it for me. need i say this stuff is complicated! good luck.

Bob your a star .

It is great to get a reply like that, fantastic help. My supplier here in Ireland can order them in for me including VAT they come to 1142 Euros. It's a bit steep but then if I had bought the wrong ones and subsequently found them not to be suitable it would be worse.

Thanks Bob for that.

Hi Tom.

I can't actually find the button link on this site for the Google connection I have to keep coming back to where you say click "here" . Anyway tiz a good post.

Paddy.

bob golding · « **Reply #48 on:** September 08, 2009, 05:27:16 AM »

hi paddy, just noticed i said 6 batteries. it should have said 8 of course. is that price for 4 of them? if it is for 8 it is very good. over here they are around 250 uk pounds for one. you will need 4 of them or 8 of them. funny i read though my post looking for typos before i posted it. still missed it.

bob

wellusee · « **Reply #49 on:** September 08, 2009, 06:39:20 AM »

Thats right Bob 4 @ 1142 Euro in all.

This is the dumpload I have been using looks rough but seems to work quite well

photo isn't great

It consists of 1" copper tube onto which I soldered a a nut and drilled through to accept the thread of the diesel heater plug the plugs are 24 volt and wired in paralell the tube body is the negative, I used 4 plugs (some spares in the photo, wasn't sure if they would last)

The plumbing side is simply a radiator on end with the tube connected top and bottom as the cold water heats it rises causing circulation in the radiator.

When it dumps over 500 watts it boils the water in the copper tube.

there is also an expansion plastic bottle allowing air and steam to exit and replacing any water that leaves the system

Wow!

Doesn't it frighten you just a little bit to be making steam inside of a system like that? I'd be scared to death the thing would blow up and kill me.

I'd be interested to see how you rigged up that plastic bottle to let the steam out and make up the missing water, maybe the thing is safer than I first imagined.

windspeed · « **Reply #52 on:** September 09, 2009, 07:56:06 AM »

the plastic expansion bottle is open at the top so pressure can't build

Does it get to the point of boiling violently?

Seems like a few bubbles would move water around at a pretty good speed, reducing the violence of the boiling.

Hi, Paddy hope yon see this on time,here is a link. Its the same resistor I used, its good for 1000w on a 24v system.http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=150370437285&ssPageName=STRK:MEWAX:IT

If the shipping cost was resonable it could be a good buy.

Check out my photos under newbies.

windspeed · « **Reply #55 on:** September 09, 2009, 03:49:41 PM »

No not violently

sounds a bit like a kettle boiling .. max watts is 750-800 from my 10 ft seems to be able to handle this no problem

wellusee · « **Reply #56 on:** September 12, 2009, 01:32:26 PM »

Hi galeforce.

Thanks for that. I'll go for it.

wellusee · « **Reply #57 on:** September 15, 2009, 01:08:32 PM »

Hi windspeed.

Thanks for the picture it looks simple enough. So you think 4 plugs will burn up to 35Amps at 1000Watts max. What's your charge control unit? I have the Morningstarr Ts60. I'd just like to be careful and get the balance right. This is the last bit of the puzzle.

If it comes to it I can build your apparatus so all is not lost .

Paddy.

windspeed · « **Reply #58 on:** September 17, 2009, 02:45:02 PM »

Hi paddy

I used 4 x 24 volt heater plugs their resistance may vary (manufacturer) so aim for .6 ohm in paralell you should be ok

your water circuit should be open vented,I use a plastic bottle inverted with a pipe connected to where the cap would be feeding into the system and a hole drilled in the base,allowing for topping up and pressure relief, keep some water in this expansion tank always

My controller is a TS 60 also so far it has been very good
