Features to look for in an electric fence charger for cattle

Having knowledge of the types of fence chargers will help you narrow the options. So, let’s see what are the essentials to have a good electric fence energizer.

Charger Terminology

  • Low-impedance

Low-impedance is the key factor affecting your choice. Low impedance means the flow of current through the wire brings less resistance. As a result, the power which flows through the wire will be more while the heat formation will be less.

The low-impedance fence energizer is suitable for large-scale fences, which need to provide large electrical intensity to maintain.

  • Solid State

Solid-state fence chargers deliver moderate current. The time required to maintain the current is not too long. This charger is suitable for short-haired animals or small pets.

  • Continuous Output

A constant output charger has a stable charger. This means that electricity will be supplied continuously and uninterrupted during the operation of the fence. This is an ideal option for dairy stalls and smaller paddocks.

Types of Fence charger

  • Plug-in (AC) Powered

Plug-in chargers are directly powered chargers. You must connect the charger to the power supply or grid that you are using to power it.

With this type of charger, you can plug it into several walls or use an extension cable.

For the electric fence energizer in a remote place and away from the power source, you should seal the path to ensure the safety of everyone around.

  • DC (battery) Powered

The DC charger is powered by batteries. This will make it easier for you to operate your fence in any place without problems. Besides, it helps you to avoid many troubles such as finding cables or sealing cable paths.

There is one thing to keep in mind when using this type of charger. The charger’s power source is the battery, and it needs to be charged on a timely basis. You should buy a few batteries to change them when others need charging.

Usually, the battery does not come with an electric barrier charger. Some batteries are rechargeable, some need replacement.

  • Solar Powered

Solar-powered electric fence chargers are almost the same as DC chargers. The difference is that you do not need to replace the batteries because the charger is connected to solar panels. When the sun is present, the battery absorbs it, turns it into an electric current, and transmits it to the charger.

You also do not need to worry when there is no sun because the solar charger can operate for 2 weeks without sunlight.

Solar chargers are usually easy to use, light, durable, and easy to move. In addition, the acid batteries of these chargers have a long lifespan, for nearly 1000 charging days.

Size and Power of charger

Many people when deciding to buy an electric fence charger are based on the numbers that the manufacturer has available. However, these are figures under ideal conditions, when the electric fence is not affected by external factors. In fact, it is never like that. Therefore, the solution is that you can use certain parameters and numbers to get an efficient charger.

  • Volt

Volt is an SI unit of electromotive force. It can be defined as the potential difference that will carry 1 ampere of current against one-ohm resistance.

Volts can help you figure out the benchmark on which your cattle could be endangered. For any kind of cattle fencing, the maximum amount of volt allowed is 7,000.

  • Jun

Jun is an energy unit in the SI system. It can be defined as the work performed by a newton when the applied point moves 1 meter in the direction of the force. Jun can help you compare with an electric energizer, so it can tell you which options are strongest.

  • Miles

Miles is a parameter that talks about the ability to charge an electric fence to successfully handle a fence of a certain length. The flow of current will be maintained for a certain length of the fence. When the fence length exceeds the permissible standard, the efficiency of the current will be significantly reduced.


A good and efficient charger not only helps keep cattle inside the fence but also protects them from predators. This depends on the electric fence charger used and the power required to shock which is also called joule.

Each animal will have a different degree of shock, so be careful to adjust the power output to best suit your herd. You can refer to the following parameters for Voltage minimum requirements:

  • Cattle and horses: 3-5 joules
  • Deer and pests: medium power
  • Predators: 3-8 joules
  • Boar: a large shock of power
  • Bear: high power


Most fence chargers have a manual to guide their users. You just need to follow the steps as instructed, you can basically install an electric fence charger for cattle. You just need to note the following points:

– If you choose the AC charger, you must connect it to a power of 110 volts.

– Pay attention to protect the charger from weather influences. If the charger box is not waterproof, put a cover around it to protect it from wet conditions.

– Always use an insulated ground wire for safety.

– There should be a separate ground rod system for the fence charger. This will ensure it is kept separate from the ground rods that your home is currently using.

– Fix the charger cover with screws or nails to limit the outside impact.

Other things to be noticed when choosing the right fence charger

Number of fence wire strands

For multi-wire fences, you can use the following rule to choose the most suitable charger. Divide your charger distance rating by the number of wire strands, and then choose a charger with a mileage rating that meets most of your needs.

Note that when adding additional wires, you should increase your electricity demand.

Amount of weeds

The weeds touch the fence, it will draw electricity and make the fence more energy-consuming. This is the reason why you should regularly treat the weeds near your fence.

If your fence has a lot of weeds growing around, you should choose a low impedance charger. This ensures that the electrical energy of the fence is always maintained at a high and stable level.

Area to enclose

When your fence is expanded, the charger for it also needs to be more powerful to provide enough electrical capacity.

The electric fence energizer will list a mileage rating, but note that this number is in the case without the influence of weeds.

Type of animal controlled

Large animals, with hooves or thick pads, require a greater shock than small animals. Similarly, large and ferocious animals like bulls or horses also need a stronger fence charger.

FAQs about Electric Fence Charger for Cattle

1. What size fence charger do I need for cattle?

Different chargers may claim to have competitive numbers on joules they can power. However, how strong your charger should depends greatly on how long the wires are.

To determine a suitable size for your fence charger, you need to measure how many miles of fence lines you have. Remember to count all the strands of wire that go around the fence. For example, 5 strands of wire across 5 miles of the fence are 25 miles in length, requiring a stronger charger.

Generally, 8-20 miles/joule is what you will find in most chargers available nowadays. But this number is not practical for normal conditions. If your fence has grass, tree branches surrounding or under rain & snowfall,  you might only get 3-6 miles/joule.

Many chargers also include their electric power by the number of acres, but don’t be confused by this. The length of fence lines will vary greatly on the different perimeters of your setting.

2. How many Volts is an electric fence for cattle?

The suitable voltage range for cattle is 2,000 to 4,000. Gentle and quiet cattle like dairy cows can be kept with lower voltage, whereas more aggressive one like bulls would require a more powerful charger.

3. What fencing is best for cattle?

High tensile wire fencing is the most expensive, but you get what you pay for. This type of fence can bear over 1,000 pounds of pressure, without losing its shape. It also requires less repair among all fences.

Hinged joint fencing can be the best to consider as they are the most cost-saving. They can also be used for horses and goats because these animals won’t get stuck in between the fence. However, a hinged joint fence won’t be as stable as other fences. So you may need frequent checks up and maintenance.

Barbed wire fencing may sound like an old-fashioned idea, but they are effective in their way. They are still added at the top of the hinged joint and high tensile fencing to keep the predators out.

4. Will a cattle electric fence hurt a dog?

Electric power of 2,000-4,000 volts running through the fence will surely hurt a dog. Your dog may feel slight pain after touching the fence. If this continues to happen more than one or two times, he may not want to go out in the yard anymore.

Our top pick
