Why Would a Fence Need a Solar Charger?

When we’re talking about a solar fence charger, we mean a type of battery that’s used to power electric fences. They are also known as a deep cycle battery, which is a battery that can be discharged to a lower voltage than the charge voltage. 

When an electric fence is triggered it sends out a high voltage pulse that will shock any animal that touches or passes through it. The high voltage pulse is powered by the solar charger battery. The solar charger battery can be used for very long periods before it needs to be replaced.

Do Solar Fence Chargers Wear Out Easily?

Do Solar Fence Chargers Wear Out Easily? No they do not. They are extremely rugged and durable. Most solar fence chargers last for a minimum 3-5 years while some can go for a decade or more. 

It is all based on the capacity of the battery and the constant weather conditions where the charger is mounted. 

How Many Joules Does a Solar Fence Charger Need To Push Out?

How many joules should a fence charger have? Your charger is going to have to be able to push out enough joules to provide voltage to your fencing. A charger should have as a minimum 1 joule per mile of fencing. This is enough to ensure the minimum current is pushed all the way down the fence. Of course, a higher amount is fine, within reason of not causing a potential fire hazard. 

Installation Ideas To Keep the Solar Fence Charger From Being Damaged

Before you purchase your solar charger, you need to make sure your installation location is the best choice. 

There are different types of locations for the solar charger:

  • Being for the most part weatherproof, solar chargers can easily be mounted to a fence posting or just about anywhere they have plenty of light
  • Make sure the charger is placed up high enough so that your livestock cannot make a meal out of it. This also prevents collisions.
  • Placing the solar charger as close to the center of the fencing will also prevent a power strain from the charger if there’s a power drop. 

Conclusion

You should now have a much better idea about solar fence chargers and what type you need for where you live. We hope you enjoyed our review article about the best solar fence chargers. 

Our top pick is going to be the Parmak Magnum Solar-Pak 12. It has the power, ruggedness and range to handle nearly anything most people are looking for in a solar fence charger.
