An electric fence energizer converts mains or battery power into a high voltage pulse. The energizer releases this pulse on to an insulated fence line about once every second. … It is the shock which deters the animal from putting pressure on the fence line.
Do you need an energiser for an electric fence?
An electric fence can be either battery or mains powered, using an energiser unit which converts the power into high voltage pulses. … Good insulation of the line so the power does not leak to earth. An earth stake that takes the current back to the energiser.
What is an electric fence charger?
Fence chargers are the heart of the fence system, providing the source for the electric current that flows through fence wire. Fence chargers, also known as energizers or fencers, vary by amount of current they output and their power source.
What is an electric fence Joule?
Energizers are rated in joules, which is a unit of energy. Your energizer must put out enough energy to deliver the right voltage along the entire fence. … Those holes are comparable to weeds, tall grass, and branches touching your electric fence. They drain energy from the fence, reducing the voltage it delivers.How long does an electric fence energiser last?
An average sized 12v energiser (designed for a paddock or medium sized field) will run for approx 2 weeks on a 12v rechargeable battery before the battery needs to be taken in to be recharged.
What is the function of Energizer?
It’s a device that takes in electrical energy from an outside source (either a 110V outlet or a battery) and then pushes the energy out through the positive fence terminal in very brief, high-voltage, high-amperage pulses. The negative ground terminal absorbs any excess pulse energy back into the energizer.
How long will a 12v battery last on an electric fence?
We always recommend the use of leisure and deep cycle batteries with electric fencing as, unlike car batteries, they are designed to be repeatedly discharged and then re-charged. This battery should have a life of 200 cycles and can last up to 2-7 years if treated correctly.
How far can Energizer be from electric fence?
You will need a minimum of 3, 6-8 foot long, rods placed at least 2 meters away from the energizer and 3 meters a part from each other. The rods and clamps are connected back to the energizer using galvanized wire. Once the fence is installed you should check to see if the fence is properly grounded.Where does the Energizer go on an electric fence?
- BATTERY POWERED ENERGIZERS Battery energizers should be mounted on a post or stand which is not accessible to the animals. …
- SOLAR POWERED ENERGIZERS Solar powered energizers should be positioned near the center of the fence line, away from shadow or animal contact.
For hogs, a minimum of 10 joules will keep your hogs where they need to be. Before I did this, my fence chargers were purchased with the miles of fence in mind, have two chargers that state they are good for 50 miles.

How many joules should my electric fence be?
Typical recommendation is one joule per mile of fence. Keep in mind that bigger is better, until the point that induction occurs. Induction will power gates and neutral wire when voltage gets too high. Anything nearing 7,000 volts may cause induction.
Can you use a car battery for electric fence?
Simply, put, car batteries are not designed for electric fence usage. 12 volt deep cycle leisure batteries (originally designed for the caravan industry) are the battery of choice. They are designed to be outdoors, in all weathers. They can cope with the constant demands of an electric fence.
Are electric fences AC or DC?
A term used to describe electric fence controllers that pulse electricity at regular intervals through a fence, typically at one-second internals. An output capacitor is used to store direct current (DC) electricity between pulses through a fence. Alternating current (AC) can’t be stored using a capacitor.
What is the most powerful electric fence charger?
The M10000i packs 100 joules of stored energy and will outperform any other electric fence energizer on the market powering 125 miles / 3,000 acres of multi-wire fencing.
Do solar electric fences work at night?
The reliance of solar fence chargers on sunlight is a benefit as long as you have plenty of sunny weather. … Quite to the contrary, solar fence chargers have rechargeable batteries. They can maintain a current overnight or during overcast weather. But too many dreary days in a row can cause the battery to run down.
How do you charge an electric fence?
Insert the batteries or attach the charger to external batteries, depending on the model. Connect the grounding terminal of the charger to the grounding rods with a piece of electric fence wire. Connect the positive terminal of the charger to the electric fence with another piece of wire. Turn on the charger.
Can you use two fence chargers together?
Only one charger should be used on a single electric fence line. Using two chargers on the same line will damage both chargers, and pose a hazard to people and animals that come in contact with the fence.
Can you charge a battery from an electric fence?
Yes you can but this is not recommended as car batteries and leisure batteries are quite different. A car battery will give out a lot of power in the first few days but then lose power gradually over the subsequent weeks and the fence will be less effective until the battery is finally flat.
How many amps does an electric fence draw?
Electric fence energisers put out high voltage (around 8,000 volts), but very low amperage or current (around 120 milliamps). This is 120-thousands of an amp. It should not even kill a squirrel.
How do you connect an electric fence to a battery?
Place two 12-volt batteries, one in front of the other, in an enclosed area next to the electric fence controller. Turn the batteries so that the positive and negative terminals are on the same side and next to each other. For example, place both positive terminals on either the left or right.
How does a fence energizer work?
An electric fence energizer converts mains or battery power into a high voltage pulse. The energizer releases this pulse on to an insulated fence line about once every second. … It is the shock which deters the animal from putting pressure on the fence line.
How does a fence energiser work?
The energiser converts either mains or battery power to create a high voltage pulse. The pulse is very short and is then repeated about 1 every second. This pulse is commonly referred to as a shock and is felt by the animal as it touches the fence.
How many ground rods do you need for electric fence?
In fact, the majority of electrical fence systems will actually require at least three grounding rods. These rods should be about 10 feet apart and should be placed at the start of the fence. Grounding rods can actually interfere with phone service as well as electrical lines that may be located on the property.
What triggers electric fence?
How Electric Fencing Works. Electric fences are designed to create an electrical circuit when touched by a person. An energizer converts power into a brief high voltage pulse. One terminal of the power energizer releases an electrical pulse along a connected bare wire about once per second.
Do electric fences keep bears out?
A properly installed electric fence will prevent bears from accessing areas of your property and can be an effective long term solution to preventing bear problems. Electric fencing can be used in many situations to effectively deter bears and other wildlife from various attractants.
Can you use barbed wire for electric fence?
When converting a barbed wire fence to an electric fence, you’ll want to remove the existing wire. Understand that electrifying barbed wire is very dangerous – people and animals could get trapped on the fence and subjected to repeated shocks as they struggle to get free.
What size electric fence charger do I need for deer?
Generally speaking your fence will need to run at 5,000-6,000 volts for deer, which you can check using your volt meter. Best results will come from a volt meter made by the same manufacturer as the energizer.
Will an electric fence keep pigs in?
High tensile fence, woven wire, and hog wire can all be used for perimeter fencing of hogs. … Hogs can easily be trained to electric fence. A two strand electric fence is sufficient to keep hogs in a desired area. For sows and growing-finishing hogs, wires at 10 and 18 inches above the ground will work well.
How big should a pig pen be?
Inside a barn or shed, plan for at least 50 square feet per pig. Ideally, your pig pen would be twice as long as it is wide. An 8- by 16-foot pen would be enough so two feeder pigs could stretch their legs. Pigs kept indoors should be protected from drafts but must also have good ventilation.
How many joules does a cow fence need?
Gerrish recommends 1 joule of output per mile of fence, regardless of how many strands of wire. If there’s a total of six miles of fence, it requires a minimum of a 6-joule energizer.
