What type of fence energizers do you use for your pasture pig set up?

Fence energizers are expensive! We picked up one recently trying to avoid the solar cause they cost more and now we regret it as the pasture we are using has no easy way to plug it in. Im curious what others are using before I go back to the store and buy the 500$ solar one we were considering the first time!

How big of a paddock are you trying to use?  What kind of wire are you using?

I haven’t bought out even looked at energizers in years, but the last time I bought a good 12v energizer, a marine battery, and a small solar panel, plus a jogging stroller from goodwill. All that was still half the price of the equivalent solar charger.

So we solved the problem and didn't need to go solar. Yet. I think I'm going to try that set up you describe for when we end up needing one. We are using the parmak 5. It shoots about 6 joules for 50 miles. It is way over sized for the 100ft by 100ft paddocks we are currently doing but we wanted to make sure that if we end up expanding itl still work. I talked to a cattle farmer who deals with this stuff and he told us to just run a string of hot wire from the energizer out to where we need it. So I ran it the 1000 feet out to where we need it. I trenched a bit of it under ground for the trucks to still go over by attaching the hot wire to a insulated house wire left over from a remodel. Its only under the surface by like 4 inches but it should be alright. Right? And since we are renting the land I didnt want to try a gate and depend on strangers to close it for the power to make it out to the paddocks. I don't know if you've ever experienced having to herd 20 pigs back to where there supposed to be but it isn't fun. So far its working!
