An acre is about 209 ft by 209 feet.
How well do your horses respect electric fencing? When we go camping, we can just use one wire for our horses. If you aren't sure if they won't test the fence or won't go under the one wire, use at least 2 strands.
So for each strand going around, you'll need about 840 ft. The maximum spacing of the posts should be 8 ft. To fence in an acre, you would need at least 105 posts.
Since that seems a lot of wire and posts to bring along, why not set up a smaller pen and just move it around every so often? That's what we do. When they've mowed down what's in the pen, move it over. You can leave one side up and set up the other 3.
