Dimensioning for optimal electric fence energiser

Hi everyone,

I was hoping to find someone with experience with electric fences and energisers here in the forum. You might be able to give me some advise.

I’m planning to fence an area of about 5 acres. The perimeter is about 600m (approx 1970 feet). Though I’m thinking about two live wires so 1200m total (3937 feet). For context the 5 acres are fenced but not with electric wires added to it yet.

I’d like to be able to tether internal fences to the perimeter. The future demand would be to energise 2 or 3 chicken electric nets (50m x 1.1m each or 167 feet x 42inch - a chicken net is longer in Australia than the longest ones in the USA I think, for some reason) and a small movable subdivision for a cow and calf (as couples of movable live wires) to be run in parcels.

As for my current situation, I have 1 chicken net plus a solar powered energiser in place (0.75 Joules capacity). The solar power energiser I have I don't think would cut for all of the future demand.

I need to buy another energiser soon anyway as I am going to add a second chicken net to our block. I was thinking to get a mains energiser now (we finally have mains power at the property) and get it with enough joules to cover the described demand in the future with ease.

Even though I am not going to install all of those elements above right now, getting the new mains energiser now makes more sense to me so I don't have to upgrade it again later.

Thank you for your help everyone.

I am going to suggest rather than planning to upgrade you plan on being able to break all of this into smaller circuits.  That way if one fencer goes down you still have something hot so not everything getting out at once.  Ideally a perimeter fence and inner fences so most stuff doesn't get out if a fencer goes down.  Low fences will be forever shorting out so they need to be separate from your main fence anyway.

Yes I need to think about that. Thank you for  the advice. 🙂

The perimeter wires were  going to be more elevated from the ground in my idea.
