What is a Solar Fence Charger?

Also referred to as a solar fencer or energizer, a solar fence charger is a device that helps generate the electrical current that runs through the solar electric fence.

Solar fencers use energy from the sun to make the power that is used to deter encroaching animals or prevent livestock from going beyond a particular area.

A solar fence charger is rated based on the current it produces.

The current that is produced is then conducted through a sequence of uninsulated, electric wires that together form a closed circuit. The fence system must be grounded.

Why Buy a Solar Fence Charger?

Having an electric fence around your farm or property is a great way to protect yourself and animals.

Solar fence chargers are a great option since they will need exposure to sunlight to cater to the power needs of your electric fence. With these solar chargers, you incur a one-time cost of purchase, and then they serve you for a significantly long time.

Whether you want to protect your pasture against intruder animals, or your livestock from going beyond your farm, an electric fence comes in handy.

There are numerous types of solar fence chargers that you can pick from including both DC and AC models, as well as multiple battery-powered options.

Among all these options, the DC chargers are the easiest to implement as they can internally store their power.

On the other hand, an external power outlet connection is necessary for the AC chargers to operate.

How a Solar Fence Charger Works

A solar fence charger works in the same way as an electric fence energizer would. The charger makes electrical current to run through the uninsulated wires, which acts as barriers to both animals and humans. The flow in the cables will inflict a painful but short shock to humans or animals that come into contact with it.

In most cases, the shock is not lethal and won’t physically harm the animal but rather make it fear to go near the fence.

However, there some instances where high current chargers may be installed for greater security, especially on homes.

Important Solar Fencer Charger Considerations Before Buying

Just like in any other purchase, there are several things you out to consider before buying. For example, you need to know about the size of the fence, battery life, and size of the animals, among others. These things will help you identify which solar fence charger best suits your needs.

The solar charger that you choose should be able to meet the requirements of your farm efficiently.

These important factors include:

Battery Life

When it comes to battery life, the longer, the better. This is the measure of your battery’s performance, longevity, or the total run time when on a full charge. With an efficient battery with long battery life, you can relax knowing that you are sorted during the cold months when sunlight is limited, as well as during the nights.

Battery life can be measured in milliampere-hours or by the number of charge cycles before the battery cannot keep a charge anymore.

Joule Output

This is the amount of energy that you anticipate your solar fence charger to produce. The amount of power that you require will depend on the are that you want to protect, which will determine the size of the fence. The larger the area, the higher the power output you require.

You need an output that will be enough to keep the livestock inside and the intruding animals at bay. The higher the joule output of a battery, the better it depends on the farm size, and the bigger the shock.

Size of Animals

Also, the kind of animals you are targeting matters. Different size of animals will require a varying amount of charge to shock them. Larger animals will need a stronger shock than smaller animals.

For example, its harder to keep large animals like a horse in that it would be to smaller animals like sheep or raccoons.

Type of Fencing

In terms of fencing, this will depend on the material used. Some elements of fencing require more charge than others and thus determine the type of fence charger you need. For example, poly wire and tape rope require more power than the steel wire fence, which is less resistant to electricity.

Also, for materials like poly rope, they need low-impedance chargers while multi-strand fences need additional power as well as coverage capability.


Since the solar fence charger will be kept outdoors, you must consider its durability, as well as its resistance to various weather components. The charger should be able to survive different weather conditions, including rain, wind, intense sunlight, among others, without any problem.

Impedance Level

With impedance, you should find a solar charger with low-impendence. Impendence means the ability of vegetation around the fence to draw current from the system, thus disrupting the electrical current. With low-impedance charger, the shock inflicted by the fence should last for just .003 seconds to avoid losing much power one vegetation.

If you buy a high-impedance solar fence charger, you might be losing considerable energy when the fence comes into contact with things like weeds or large animals.

The low-impedance chargers are an ideal option as they can push more current through the wires, unlike the solid-state chargers.

Conclusion on Best Solar Fence Charger

Whether it’s a small garden or a vast pasture, protecting what is inside is paramount for the farmer. We have to protect the livestock from predators. Also, we need to protect plants from herbivorous animals which may spoil our harvest.

I believe that this best solar fence charge guide has everything you need to enable you to protect your farm, or contain your livestock, especially if you want to go off-grid.
