Once a predator tests the hot wires, it won't be back or will steer clear of the hot wires. A DC battery charger would work better in my opinion than a solar fence charger. I have several game cameras up on my property. I'm sure this coyote is teaching her young to steer clear of the coops and hot wires. They know the chickens are there. I don't shut the pop doors but nothing has gotten past the wires.
Understood, but, I can't run hot wire around my house...well, I guess I could. We prefer to not invite bears, at all, up the cliff, so remove the food at night.
