Best Solar Electric Fence Chargers

The technology behind a solar fencer is very simple. It comes with a solar panel and a battery pack. The solar panel is meant to power up the battery, which electrifies the fence when some animal comes across, pushing them away from crossing your fences.

In other words, the stored power gets transferred to the fence connected when there is an animal in contact with it. Each solar fencer comes with a specific distance range, output power, and other specs.

1. Do Solar Fence Energizers Work?

Harnessing solar energy for powering your fence is indeed a great idea. It makes use of otherwise wasted solar energy to electrify your fences in order to safeguard your land and farm from nuisance animals.

Of course, solar fencers work. If you are located in a place with good sunlight, solar fencers will work exactly like traditional fence energizers.

However, as per the power and capacity of the model you own, you can electrify the fence of your properties at no cost after installation.

2. How Long Do Solar Fencers Last?

It depends on the battery capacity and power of the model you have. On average, a solar fence charge can store enough power to run the energizer for up to two weeks with no sunlight.

However, if you have a larger battery pack or additional battery support, it can keep your fences electrified for longer, for sure. Anyway, it is an incredible idea to rely on solar fencers to keep your fences charged for staying away from wild animals.

3. Can Solar Fence Chargers Kill Animals?

No, they don’t. Like traditional fence chargers, solar fencers only deliver low currents, which can neither kill nor permanently hurt animals. However, you should keep children away from the fences electrified by any means.

4. What is the Best Solar Fence Charger? 

There are many brands that sell awesome solar-based fence chargers.

To name a few, Zareba, Parmak, Fi-Shock, and Gallagher are some of the leading brands. We have listed a number of the coolest solar electric fencers on our list. You can certainly find a matching model that meets your needs and budget from our compilation.

Why Solar Fence Chargers?

Solar fencers are great solutions to protect your remote fences from nuisance animals as well as to contain your livestock inside your farm or home premises.

Of course, you will find it hard to take grid connectivity to the distant boundaries of your properties to provide electric current to the fences. There you have the most reliable solar solutions. As you see, they simply let you make use of the electricity from the sunlight and convert it to fence strings.

Of course, the size of the fence energizer is key in selecting a unit for your property. On our list of solar fencers above, we have various models suitable to the properties of 3 miles to 30 miles. The size comes out to be a factor as it should provide enough current for both the length of the fence and the type of animal.

A low-powered fence charger can only control small animals on a small property. You must be looking for a high-powered variant to prevent larger animals from entering your garden or farm.

How Do Solar Fence Chargers Work?

Solar fence chargers work exactly like a normal electric fence energizer. Both leave a short and painful shock on an animal or a human that comes in contact with the fence.

The shock is indeed safe and won’t cause any physical damage to the animal. The normal fence energizers and the solar fencers vary in the fact that the latter receives the power for the shock from the sunlight. That is all. The rest is the same.

How to Use a Solar Fence Charger

How to Use Solar Fence Chargers?

As you know, solar fencers are ideal to secure isolated pastures and gardens from nuisance animals. In fact, there is a wide variety of solar fence chargers on the market depending on the size and the output.

You can find solar chargers small enough to keep a rabbit out of your garden and large enough to contain a bull and everything in between, for sure.

Of course, it is very easy to set up a solar energizer. You don’t need to be an expert technician to install it. In some simple steps below, we have a complete guide on what to do with a solar charger out of the box.

1. Unboxing and Initial Charging

Before installation, you need to boost its battery by recharging it from the sun. That is to ensure optimal battery life for the device. For that, you can place the device somewhere in a way the solar panel would face the sun throughout the day.

Wait for around three days to fully recharge the battery. Typically, a fully charged solar fence charger can operate the device for around two weeks without the sun.

2. Mount the Solar Fencer

The next step is to mount the energizer near your fence. Most solar fence energizers come up with built-in mounting brackets that support a variety of post types.

Make sure you find an ideal location to mount the charger off the ground. The location should have enough sunlight and ensure the solar panel on the device comes in the face of the sun.

3. Connect the Fence to the Energizer

Next, connect the ground wire to the ground terminal hook of the fence charger. Then, connect this wire to a ground rod system using insulated cords and ground rod clamps. After, you need to connect the fence wire to the fence terminal of the energizer to pass the current.

4. Turn on the Energizer

After you successfully make both connections, it is time to turn on the unit. Make sure the unit is working by checking the Fence OK light.

By the way, use a voltage tester to check whether your fence has got adequate voltage. Keep checking the voltage at multiple points of the fence and if you see the voltage everywhere, you have done the installation job successfully.

5. Clean the Solar Panel

Of course, you need to occasionally clean the solar panel to remove the build-up of any wastage. It is to make sure there is no debris on the panel to block its exposure to the sun.

Apart from cleaning, a solar energizer needs virtually no maintenance at all. You need to only clear the external factors like weed growth over the fence to avoid voltage loss.
