Why Should I Buy Solar Electric Fence Charger?

Solar electric fence chargers are ideal for remote pastures where you don’t have access to AC wiring. They are efficient and save you money over time thanks to their ability to provide power from the sun, which you don’t have to pay for.

They are able to protect anywhere from less than one to 100 acres of land, depending on the size of your pasture and the type of charger. The different sizes factor into how much length and the size of the animal they will work on.

A low-powered fence charge is generally only effective on small animals, so a high-powered model is typically needed for horses and livestock.

Another advantage of solar chargers is that they will still work during power outages. The power from the charger that is stored gets transferred to the connected fences. They come with a distance range and output, so it is important you find a model that works with your fence length.

How Do Solar Electric Fence Chargers Work?

Solar chargers work by electrifying the fence and recharging the electric fence battery from sunlight during the daytime. They are generally easy to install and typically won’t run out of energy. You don’t have to worry about installing AC wires across pastures to hook them up.

If you’ve ever accidentally touched an electric fence, you know that it does not feel good.
Solar electric fence chargers, just like regular electric fence energizers, work by inflicting a short yet painful shock.

Though the shock may be uncomfortable, it is safe and won’t cause physical damage to animals or people. Solar electric fence chargers work by collecting energy from the sun and turning it into an electric current that will cause a shock if touched.

How To Use a Solar Charger

Solar fence chargers are ideal for isolated areas in order to keep animals in or out of an area. They can range anywhere in size from keeping a rabbit out of a garden or keeping livestock in a large pasture.

Installing a solar electric fence charger is relatively easy, but it is important that you know what you are doing. You must properly set it up in order for the electric fence to be effective.

Charge the Battery

Before installing it into a pasture, you want to allow the battery to fully charge. Allow it to receive three to four days of sunlight in order to recharge. This will allow for optimal battery life.

Mount to a Fence

Once the battery is charged, it is time to mount it to the fence. Most solar chargers are designed with built in mounting brackets for easy installation. You want to make sure that it is mounted off the ground and in an area where it will receive plenty of sunlight.

Connect the Fence to the Charger

Once it is securely mounted, connect the ground wire to the ground terminal hook of the charger. After that, connect the wire to a ground rod system by using ground rod clips and insulated cords.

The fence wire then needs to be connected to the fence terminal in order for the charger to pass the current.

Turn on the Charger

After everything has been hooked up, it is time to turn it on. Most units will have a light to display if it is working. You can use a voltage checker on different parts of the fence to make sure it is successfully running.

Clean the Solar Panel

In order to keep the unit running properly, you have to regularly clean the solar panel. Make sure to clean off any debris that may get on the panel and trim any weeds that are interfering with its ability to get sunlight.


What Voltage For Electric Fences is Recommended for Horses?

For horses, the recommended voltage is 2,000-3,000 volts in order to be effective.

What Are Joules?

Joules are a unit of energy that represents watts x seconds. A fence charger needs to have adequate joules in order to push the voltage down the fence line and through a load.

Can an Electric Fence Kill You?

An electric fence can not kill you, be debilitating or burn you if you touch it, but it can hurt for up to 10 minutes. Electric fences have low current and pulsates, which can not kill you or cause permanent damage.

How Many Ground Rounds Do I Need For an Electric Fence?

The general rule to follow is that you should install a minimum of three feet of ground round for every joule.

What Happens if You Don’t Ground an Electric Fence?

If your electric fence is not properly grounded, this can cause the shock to not be powerful or even felt at all. Be sure to follow the instructions of your charger to make sure it is correctly installed.
