What Is A Solar Fence Charger And How Does It Work

To put it simply, a solar fence charger is one of the major elements needed to operate a solar-powered electric fence system. You will hear it being referred to as a solar fencer or solar energizer.

They are categorized according to their power output level. This charge is diffused through a sequence of electrical lines creating a grounded closed circuit.

In other words, the system is grounded and the wire and fencer loops to a full circuit so that touching the hot wire exposes someone to the maximum circuit voltage.

This set up allows current to flow along the un-insulated wires as long as the charger is operational. It is these live wires that electrify any person or animal that touches it.

The level of power running through the system dictates the amount of shock a person or animal receives, ranging from fatal electrocution to a small jolt.

In so doing, the fencer system acts as a restrictive barrier for people or animals who wish to cross the fence.

Factors to Consider When Choosing the Best Solar Fence Charger

Range Capacity 

One of the most important factors to consider when deciding on a solar electric fence charger is the range capacity, so that you can get one that matches the length of your fence. If you choose a charger that is lesser in range capacity than you need for your fence, then there will be performance problems as time goes by.

Every solar fence charger is engineered to charge fence lines to a predetermined length. The charger’s range capacity is based on the open-circuit current flowing through the device and the approximate electrical energy dips across the lines.

You need to check with the manufacturer so that you can find out the range capacity.

Type of Animal and Voltage

Another crucial thing you need to consider is the kind of animals that you want to secure or repel from your property. The power specifications vary based on the animal size you are looking at.

For example, larger animals like moose or cows may require approximately 4,000 volts minimum to produce a potent electrical jolt to make them stay within or away from the perimeter.

On the other hand, cattle and horses would need around 2,000 volts running through the fence line for an adequate jolt.


Electric fence chargers usually give information about the joules output. It’s a way to measure the energy level of the charge. A joule unit is commonly found by watts X seconds (W x S).

For fence energizers, a joule tells the potency of the electrical jolt that the person or animal in contact will have. When all is said and done, the shock potency and the resulting harm is based on the level of electricity deposited through the person or animal.

Because Watt = Current x Voltage, therefore the voltage determines the jolt they get, along with the current, and other factors. You would have probably guessed that the greater the joule output, the higher the electrical charge.

To protect or ward off bigger animals like predators, you will need a greater joule output so that it will generate a shock that will scare the animal away from the fence. Especially if the animal has a thick hide.

Fence Wire Use and Weed Conditions 

There are different current settings provided by the makers of solar fence chargers. One of them is an open circuit voltage, which is simply the amount of charge flowing through the fence when there is nothing touching it, including weed and grass or people and animals.

The solar fence charger you buy should be labelled with the level of shock, based on the animals you wish to contain or ward off. Even so, abundant weeds and bushes can reduce the power running through the poly tape, steel, poly wires, or rope fence line.

Because of this, you have to look for the charger voltage stipulated by the maker, under light, medium, or heavy weed environments. You must also consider the kind of wire that will be used for the fence and how this will affect the energy production. Steel tends to be the best conductor and always works best.

Different Types of Solar Fence Chargers 

Solar powered fence chargers can be categorized into three main categories.

· Firstly, we have the solid state fence charger that can distribute an average level amperage jolt in pulses/beats of standard intervals. Perfect if you want to contain animals with short hair and you have fewer problems with weeds and bushes.

· Secondly, there is the continuous output fence charger which offers continual voltage along the hot wires, which contrasts the pulse chargers. Obviously, this type would require more energy and pose a greater risk. Because of these factors they are for the most part scarce in the modern market.

· Lastly, we have the low impedance technology charger. This solar fence has a revolutionary type of engineering for impedance, which simply means that it is made to have effective resistance to opposing current in the charger. The result is that greater level of current can run through the wire lines. There for weeds and bushes have less effect on voltage levels.

Advantages of Using a Solar Fence Charger 

Solar powered fence chargers have many advantages including:

You can save money

If you live in remote locations where electrical power is not easily accessible, then you would need to cover the cost of a new electrical installation from the power company in your area. If you invest in solar technology, the power source would be the sun, saving you a lot of money that would be spent on wiring.


The cost of new installation and wiring work in not the only hurdle of living remotely. You also need to consider the terrain, and whether or not AC power cable would be able to safely get to your location in the first place.

The installation would need to be safe and approved to prevent fires and explosions and take into account all the wildlife or forest. But with solar energy, the power comes straight to your location, providing you with life altering amenities and technological luxuries.


It’s a great feeling when you don’t have to rely on the utility company to complete vital work or even save your life. Electric power companies frequently have power- outages, blackouts and even short-circuits, which can be a major inconvenience to you and your plans.

This would mean that the fence charger would have no electricity, and your animals could escape or pests and intruders could enter your premises. If you have solar powered electric fences, you will eliminate this hassle. Solar powered electric fence chargers have a less chance of damage caused by lightning strikes because most of them have built-in lightning diverters.


Solar powered ‘anything’ is known to be more environmentally friendly. This is probably why more and more people are going in this direction.

Disadvantages of Using a Solar Fence Charger 

Reliance on Sun

Because solar fence chargers depend entirely on the sun for power, you will have a problem on gloomy days and especially in the winter. It’s important to select solar fence chargers that can store the energy collected and maintain output for long periods.

Expensive Upfront Cost

The primary start-up cost of installing a solar fence charger is a bit steep for most. Of course this would eventually pay for itself because you will not be paying a monthly fee for the power grid energy to use your fence, but initially it may break the bank.

If you have electrical knowledge then this works out well for you because you can do the installation yourself, saving a lot of money.

Weather Dependent

For people who live in areas where there are low light and harsh weather conditions, solar power may be less beneficial to you. For some people, the use of an electric solar fencer would be out of the question during some seasons.

How to Install and Safely Operate a Solar Electric Fence Charger 

It’s important to understand that, electric fence chargers are engineered to produce voltage shocks or harm on contact. Hence, it’s very important to know how to carefully and effectively install and use an electric fencer through a series of steps.

Step 1 – This is very important! Ensure that the charger is turned off before you install it on a post. This is because the battery within the charger will most likely have some charge. If the charger is on when you connect it to the hot and ground terminals, you could suffer electric shock. If you are installing a powerful charger, this could be very dangerous.

Step 2 – When you have made sure to properly follow the package guidelines and installed the charger, you need to allow it to collect sunlight for a specified amount of time. The instructions on the package will direct you but it should be around 3-4 days of direct sunlight so the solar panels could recharge the battery.

Step 3 – You need to perform the necessary tests to make sure that powered electric fence charger is working, after you put it on. On most chargers there will be an indicator light so that you will know if the fencer is operational.

· The first test you should run is on the meter. You need to ensure that it is working.

· Secondly, test the batter to see the status of its charge, so you will get some idea of the stored power and maximum capacity.

· Lastly, test the voltage output of the fence in a usual setting. The meter shows the open-circuit value of the charged fence.

Pay special attention to the grounding system so that you fence will keep working.

Final Words

Undoubtedly, the best solar fence charger, is the Parmak DF-SP-LI Solar Pak. It’s low impedance which means that it has an effective resistance to alternating current and features a special built-in performance meter, so you can be updated on exactly how it’s doing.
