What Is A Solar Fence Charger And Who This Is For


Fence charger provides the electric current that flows through and runs down the fence wire. Also called as fencers or energizers, they are mainly used to keep wild animals from entering your property.

Solar fence chargers work very much like the normal electric ones. However, they give you the advantage of going solar. With this, you will be afforded the protection and the other benefits of the fence charger despite black outs and power failures.

A solar fence charger gives you a cost-efficient and economical way of protecting your property. The electric current gives quite a shock when touched. As such, you can effectively keep animals from going and from going out.

Because of this, they are quite popular among the farming community. With this, they can control their livestock as well as protect them from wild animals like wolves, foxes and wild dogs.

Moreover, they are also popular among homeowners who seek to improve and enhance their home’s security. Some models even offer extra safety and security features.

Since they are solar, solar fence chargers are also quite useful especially if you live quite far from the electrical grid. With this, you would not have to spend much installing new lines and wires.

How Does It Work

Solar fence chargers are beneficial for those who would like to enhance the security in their home or those who live near forests. It is also useful for those who own and raise different livestock.

This is because the fence charger gives an electrical pulse when touched. A0s such, when an animal or person touches it, they can feel a short burst of pain. However, this shock does not cause any physical damages.

Overtime, the solar fence charger acts a strong and effective psychological barrier. Remembering the pain, intruders or animals will avoid coming into contact with the fence to avoid the shock.

The solar fence charger has 5 main components.

The first component is the solar panel that is responsible for the collection and the conversion of solar power into electricity.

The second part is the regulator. This is connected after the solar panel and is likewise important since it regulates the amount of electricity flowing into your battery. With this, you can prevent the battery from over- and undercharging.

Next is the battery and it is responsible for storing the energy converted. How long the solar fence charger will last depends on the battery’s charge.

The fourth part is the energizer. This takes power from the battery and distributes it to the whole fence. The size of this depends on the area you want to fence.

Last is the grounding. For a solar fence charger to work properly, it must be stable and grounded properly. Moreover, this is also done for the user’s safety.

What Are The Different Types Of Solar Fence Chargers


A solar fence charger is quite useful especially if you have livestock and for those who want to enhance their home’s security and safety.

This is because the solar fence charger generates a shock that can be used to keep animals in, as in livestock or used to keep people or wild animals out.

There are three main types of solar fence chargers in the market.

The first type is the continuous output fence charger, such as a solar fence charger for horses. As in its name, this type provides a steady and continuous charge on the wires.

This is different from the electrical pulses given by the other solar fence charger types. In other words, the wires are constantly charged all the time.

Because of this, they are not quite safe to use, especially if you have children or pets. The charge may cause quite some damages. Aside from that, they also consume a lot more power compared to the other two types.

The continuous output fence charger is typically recommended for smaller areas or dairy stalls. However, these types of fence chargers are quite rare these days.

The second type is the solid-state fence charger that is what most people recommended for livestock protection.

This is because this type only delivers a medium voltage, so it is not quite as damaging like the first type. They also only deliver such shocks in medium durations. As such, it would not eat and consume as much power.

Because of the low shocking power, the solid-state fence charger is best for taming and keeping in smaller animals and those with very little fur.

The solid-state fence charger is also recommended to use if you have steel or aluminum enclosure. With this, the charge is more effective.

However, weeds can impair and affect the performance of these chargers. Thus, you need to ensure that the area is clear of weeds and other vegetation.

The third type is the low impedance technology charger that is one of the newer models. Low impedance chargers basically solve the dilemma of solid-state fence chargers.

Here, there is lower resistance in the charger that results into more power flowing through the fence. As such, it delivers shocks of higher voltages.

They are best used for bigger livestock such as cattle and horses. You can also use them for furry animals.

Low impedance chargers also boast the latest technology. Normally, weeds and vegetation affect the performance of most solar fence chargers. In the worst-case scenario, weeds will ground the fence and cause a power shortage.

However, lower impedance chargers can still provide power despite the number of weeds blocking their way because they can generate more power. As such, they provide a solution for lands heavy with weeds as well as for longer fences.

Advantages And Disadvantages Of Using A Solar Fence Charger

Knowing the advantages and disadvantages of a product is essential for a buyer as it helps him/her make the final choice. With this, the buyer can determine if the product can suit and satisfy most of their needs.

Moreover, solar fence chargers also give you the freedom of going off the grid. Since you do not need to rely on electricity, you would not have to worry about using the device for long periods of time.


Solar fence chargers offer a convenient way of protecting and shepherding your livestock. Due to the electrical pulses, generated, wild animals like wolves, foxes and wild dogs will be discouraged from getting in your livestock.

On the other hand, your livestock will also be barred from going out as they please.

Security Measures

Solar fence chargers like a solar electric fence charger for cattle can also be used to ward off intruders and other unwanted guests into your house. Once they touch the fence, the solar fence charger will transmit an electrical pulse that will certainly shock and discourage intruders from entering your property ever again.

Great for big and remote properties

Solar fence chargers are beneficial for those who have big properties and for those who live in remote areas.

Big properties can benefit since these devices offer an efficient but cheap way to secure your home and/or protect your livestock from intruders.

People who live in remote areas will also appreciate the solar fence charger since these areas have limited access to electricity. As such, in times of power failures, the solar fence chargers will still work.

Moreover, they also eliminate the hassle of installing additional power lines or wires just so you can connect the fence charger to the grid.


Reliant on the sun

Solar fence chargers rely heavily on the sun’s energy. As such, it may not perform as well or as long in cloudy days, or during winter season.

How We Picked And Tested


Solar fence chargers offer an efficient but cheap way to keep wild animals and intruders alike at bay. Since they run on solar power, they are also helpful to the environment.

Aside from those mentioned, solar fence chargers offer numerous other advantages. In fact, they have become quite popular among homeowners, farm owners or those who own and raise livestock. In short, they are a great investment.

However, there are currently a lot of types and models available in the market. This makes purchasing one a bit difficult.

Of course, the perfect solar fence charger depends on how well the model can satisfy your needs.

But to get you started, here are a few essential factors to help you make the right choice.

Range Capacity

Solar fence chargers are effective since they provide some sort of an electric barrier around your property or enclosure. As such, purchasing one with an incorrect range capacity will result into the underperformance of the product.

This factor is dependent on the length of your fence and the number of wires it has. So, before you buy one, check how long your fence is and how many wires it has.

Voltage Requirements

Aside from the range, one important feature of the solar fence charger is the voltage.

Solar fence chargers are effective since they transmit powerful but safe electrical pulses on unwanted animals or intruders. These pulses depend on the product’s voltage. Voltage depends on the type of animal you want to keep out.

Big animals such as deer, goats, and predators need about 4,000 to 5,000 volts, depending on the fence type and design.

For bulls or bison, the product should produce about 3,000 to 4,000 volts.

If you have medium-sized animals like cows, horses and pigs, a solar fence charger generating 2,000 to 3,000 volts is the most suitable.

Nuisance or pests such as rabbits, wolves, foxes and wild dogs, a 1,000 to 2,000 voltage are enough.

On the other hand, if you only have pets or poultry, then a voltage of 500 to 1,000 volts is more than enough.

Type of Solar Fence Charger

Of course, you also need to take note of the different type of solar fence chargers available in the market. Currently, there are three, namely the continuous output fence charger, the solid-state fence charger and the low impedance solar charger.

Different types offer and cater to different needs. for example, continuous output fence chargers are great for small spaces or for dairy stalls.

The second type is great for taming small to medium animals with little to no fur. The third type is top-tier for areas with dense and heavy vegetation and weeds.

However, it is recommended that you get the third type. it is not only because it offers the latest technology, but it is also the most efficient out of the three.

While it is best to keep your fence clear from weeds and other plants, the low impedance model will still work even in times you don’t.


Look for models with U/L or CSA listing. This ensures that the product has been thoroughly tested by the appropriate authorities and is completely safe to use.

Aside from that, make sure that the product is made out of high-quality materials and is built to withstand harsh weathers. The housing on your charger should be made out of steel and protected against corrosion and other elements.

Extra Features

Some solar fence chargers come with extra features such as performance meters and the like. These features are discretionary and depend really on your personal preference.


A good solar fence charger is also one with a good warranty. Find a product that offers 1 to 3 years warranty and one that covers repairs and replacements.

Frequently Asked Questions


How many Joules should a fence charger have?

The University of Missouri Forage Research Center recommends distributing one Joule every 0.5 to 6 miles. The exact figure will vary based on factors such as perimeter material and whether it’s a single or multiple strands. The more strands the fence has, the higher the Joules/mile rating should be.

Most people use the highest Joule solar fence charger they could buy to deter their livestock from going outside the perimeter and prevent wild animals from encroaching the property. That said, one Joule per mile is usually more than enough.

Many chargers have a Joule rating between 0.10 and 1.0. For example, the Patriot fence charger PE2 only has 0.10 Joules, while the Patriot PE10 has 0.30 Joules. Note that these products connect to a 110-volt circuit, not a 12 volt battery. In contrast, the Gallagher S12 has 0.12 Joules but can cover 4 miles of fence using sunlight to power it.

Can you power other solar devices using your solar fence charger?

No, you cannot do so. A solar energizer for electric fence has electrical output parameters that might be incompatible with other solar-powered appliances, such as lights and heaters. The unit delivers a high-voltage current to damage to shock the target animals, which might not be suitable for powering other electrical devices.

Another reason a solar fence charger is incompatible with other solar devices is its modest amperage rating. For instance, a 7,000-volt solar fence charger might only deliver 150 milliamps. Other solar devices might need more amps.

It is always sound advice to use a charger designed specifically for your solar device to avoid potential problems.

How long does it take to charge a solar fence charger?

A solar fence charger’s charging time depends on the brand, photovoltaic cell technology, and environmental conditions. For example, the Zareba 10 Mile Solar Low Impedance Fence Charger requires 48 hours to charge fully. Other brands might require three to four days to charge.

Even the most powerful and strongest electric fence charger would require intense direct sunlight for extended hours to collect as many photons as possible to convert into DC electricity. Shading, overcast skies, and shorter daytimes can reduce light exposure, decreasing electricity production and extending the charging time.

The solar fence charger’s photovoltaic cell technology can also affect a device’s charging time. Monocrystalline panels can convert 15-20% of sunlight to DC energy. Newer monocrystalline technology can even reach up to 22.8% solar efficiency. Meanwhile, polycrystalline PV cells only max at 16%.

The higher the solar panel’s efficiency rating, the faster the charging time, given optimal environmental conditions.

How long do solar fence chargers last?

A solar fence charger’s longevity depends on the brand. For example, Zareba’s solar fence energizers for garden and property perimeters can last two weeks when fully charged and without sunlight. With systems like the Zareba’s, there’s no need to worry about power interruptions, overcast skies, and stormy weather.

As for the chargers’ longevity, it’ll be wise to read the product’s technical specifications. You might want to check the accompanying warranty to know the device’s operating lifespan. Although relative, product warranties provide a rough estimate of how long the solar fence charger will last with normal use.

In general, you can expect these devices to last 3-4 years. If they fail, you might want to change the batteries first to see if they can still power up. Only get a new one if your old charger fails to work even with the batteries replaced.

What are the most trusted solar fence charger brands?        

While you can find many brands on the market when finding fence chargers, you might not be able to get a top quality one without considering a reliable brand.

Some of the most popular in the category include the Zareba, Parmak, Fi-Shock, Gallagher and Silver Streak, to name some. Check them out when choosing a fence energizer.
