Solar Electric Fence Energiser

[stablegirl]

We have a 60 acre lump of ground split into paddocks with electric fence, which comprises of 2 strands of high tensile plain steel wire, there is a total of 3km of fences about 6 km of wire, in about 7 different fences.

In previous years these have all been run by seperate battery powered fence units but the cost of batteries over a season adds up.

If i connected all these fences by digging undeer the gates and linking them with insulated wire would i be able to run them with a single solar powered fencer such as this...........http://www.rappa.co.uk/products/240...co.uk/products/240-s500-solar-fence-energiser

Cheers

You could run that lot off one fencer, but i’d Be wanting something a lot more powerful than a 0.5J tiddler.

Could you connect them up anyway, then just run them off a decent fencer, battery or solar? A solar panel will help out a more powerful fencer, but you’d need a huge (& expensive) panel to remove the need for recharging batteries at all.

Two summers ago I installed a 50w solar panel and charge controller (off of ebay, quite cheap) together with a new 110ah leisure battery onto our energisers. The first winter the batteries needed charging twice, this winter they have not needed charging once (you must get the panels at the correct angle and pointing in the correct direction with nothing to shade them). This is with a 2.0 and a 3.2J enegiser. This is with the energisers set to low speed. If you want high speed you'd want a 70-100w panel due to the short sunlight hours in the winter.

The cost for the two panels, batteries, mounting hardware and electrical bits to connect it all up was under £500 (I think just over £200 per enegiser) and a mornings work to install. Since tweaking the position of the panels this has proved to be a maintenance free solution. Just some food for thought.

I'd estimate that you will need 3 of those 0.5 Joule fencers to run your fences. I use solar for my fences but its a much larger panel than the ones the fencer manufacturers supply built into the unit charging a leisure battery.

When you are running leads under gateways to make the circuit, use a proper wire for the job with a big cross-section of wire and thick insulation, not a bit of weedy mains wire, or you will lose power at every gate. Good idea to prevent future damage is to bury it in a steel pipe, or at least run it through blue plastic water pipe while you are at it.

I have learned this after running miles of single strand for paddocks when we were milking!

I should have added i only want to run it through the summer.

This one is quite a bit bigger?

Looks very expensive for what it is, I bought a 10W unregulated solar panel off ebay for about £30 to run a 2J fencer. With larger panels you need a regulated one as they can overcook batteries, if the fencer gets turned off on a summer's day. . We use double insulated lead out cable and run this through blue pipe under gateways etc.

Does any vegetation grow and touch the wires? Brambles, nettles etc will soon cause trouble without a big unit to burn them off.

Have a loook at voss energisers. You get a lot more bang for your buck.

So if i was to go down the separate solar panel and energiser route what energiser would you use?

I was thinking of making a frame to keep it off the ground anyway.

Just testing out this set up with A 300W panel and a voltage regulator

If good well insulated fence line around 2 joules output power be plenty I'd say.
What battery powered units do you already have?

Also done pretty much the same .. a 50w panel and decent battery will run a 2j unit all summer on low speed just fine- no vegetation or shorts without any charging and at least 3x the recharge period of a battery alone in the winter. I've got 3 panels mounted on old road works sign frames - perfect angle but need tethering else they blow over. Just connect it to battery with croc clips.

For the op's game plan he'd want at least a 3j unit, 100+w panel & charge controller facing the right way and not too much vegetarion. The link he posted might just keep a horse tape live on a good day. They're incredibly expensive for the pee all power they produce.

Cheers so it's joules I'm after!

Is it stored j or output j I'm looking for?

This one too big? https://www.electric-fence.co.uk/voss-farming-sirus-8-12v-mains-energiser.html

 

[Bury the Trash]

Output.
And look at the volts its capable of when theres resistance ie what you get in real life when sending the power down the wire losing a bit as you go because of the

Longer fence or smaller wire etc and constriction that causes taking power away from the shock the animal gets as the ohms In crease
In those figures they list 500ohms..... see how the volts figure is down..?

no its not too big. should be ok ir ...nice little unit?
and you could go bigger than that if you want./can afford. but it will take more battery power the bigger you go.....drain yer battery quicker....


but its only cattle ?

look at their claimed km 's figures under heavy vegetation.... as a worse case scenario situation......

Pikeys love solar panels and batteries !!!!
