Solar chargers are actually much more expensive per output than a plug in. I currently use a lead wire perimeter, then attach the smart fence to the lead wire for power. In the past, I have used the "ranch king" , a solar powered charger, which they don't make anymore. I was not super powerful, but it did the job just fine. My ranch king lasted for 6-7 years until the battery quit charging. It still works on sunny days....just not at night or on cloudy days.<L>
The amount of juice you need depends on your total length needed at one time and the type of animal. A single strand of hot wire that just fences a single paddock at a time doesn't need as much juice as one that runs for miles and needs to fence multiple paddocks at the same time. Smaller animals take more juice because they aren't as conductive as larger animals.
When I called my local representative, I described what I was trying to do and she let me know exactly what specific chargers would work. Fortunately, the plug in one I bought on sale before I anything about chargers, will probably do the job.

We.ve had the best luck with Pel energizers, both battery and electric. I use a 12 volt marine battery for power, and the energizer stays in a fixed area. I run a wire for electrifying from the energizer. You have the best luck with a fixed energizer location with at least 2 ground rods. We use them for cow fence (one wire) in addition to electronet for sheep, and feathernet for poultry, and this is all at the same time.
Fifteen years ago our energizers were about $100, we use the heck out of them and they are still working great! The 12 volt batteries hold a charge for about 5 weeks, I have two and keep one charged in reserve in case of emergencies.
We've used Parmak Solar chargers and have had them for years, too. Once our critters find the hot wires, they usually don't try it again! ha! We don't have rotational, grazing though..we've just never had an issue with this brand. And we keep on e spare battery on hand and charged, just in case... ~Deb in GA
I use a Parmak battery powered fence charger. It works well and runs off a 12v car battery. So we have 2 batteries...one that is charged and one that the fencer is using. Plus, it wasn't a real expensive fence charger.
Thanks guy! SO glad I asked before I bought it! I thought it was the whole shebang, not just a battery. I went to my local feed store, told them what I was looking for and they recommended the Gallagher B10 which is a little tiny energizer that runs on D cell batteries. I only have two cows (well, 1 cow and 1 heifer calf) and they will just be in a 30'x30' paddock that gets moved every day; so small is good for me!

if your cows are not already trained to electric fence I would recommend putting a length up in the middle of their paddock or yard etc. They'll get curious and test it and as long as it is hot they will learn about electric fences before you need to count on the fence to keep them contained. If you are getting a battery powered charger, really stay on top of the batteries and the charge. It's not fun to have cows who dont respect the fence.
