Which Fence Charger Do I Need?
To understand what a fencer is, first you have to learn the basics… How does an electric fence work?
After that, you will see there’s a wide variety of Fence chargers from which you can pick, and within each of them, you still have multiple choice. This can make choosing the product for you quite frustrating. That’s why we are here to answer your questions. What makes each charger different? What type of size and power do I need for my charger? How can I decide which one is for me?
Don’t be overwhelmed! Here you can find the answers to these questions, summed up in just one guide. We will definitely educate you all about fence energizers.
- Low-impedance – A low impedance fence energizer means that it has less resistance, this leads to more power pushed through the wire. This type of electric chargers are better, they are part of the latest technology for land with weeds.
- Solid State – These chargers deliver a medium amperage of shock pulses at a medium period. They are great for controlling shorthaired livestock, small animals, and pets. They perform well with light weed existing conditions.
- Continuous Output – This term means there is an unbroken, stable charge on the hot wires as opposed to pulsing charges. These steady systems are recommended for dairy stalls and smaller paddocks.
Types of Fence Chargers
AC (Plugin) Powered
This type of charger are powered directly by a connection to the electrical grid you have. You can plug it in your barn wall or use an extension cable to an energizer housing closer to your fence.
However, the AC chargers need to be plugged into a wall at some point. This makes them easy to use, yet, this isn’t a good option if your fence is in a remote place, that just makes them impractical in this case. If you need sealing the paths around your house you might be interested in checking our article about the paver sealer reviews.
DC (Battery) Powered
If you have an off-grid farm you still have 2 options to choose from. One of them is the battery-run fence charger, which is perhaps even simpler than the AC charger. That’s because it draws its power from an internal or external (depending on the type) source, instead of being plugged into a wall.
This makes them easy to use in remote locations. You should also consider how you could clean the snow from your pasture during cold weather. If you want more information about that, you can check our piece about the top-rated ATV snow plow it can be especially helpful with secluded areas.
However, they need to be recharged from time to time, in order to keep the fence up and running. If you don’t want to leave your fence without protection, you can invest in a few DC batteries and swap them every time one of them needs to recharge.
Usually, batteries wouldn’t be included with the charger and some of them can be recharged, while others need to be replaced. People often ask: How frequently do they need to be charged? The answer: It depends on how many times the fence is grounded. What that means is, if the animals are touching the electric fence often or if there are weeds around, or their limbs touch both the fence and the ground, the battery of the unit will be drained faster than if the wire remains clear.
If your animals are trained to avoid the boundaries then you will have amazing results. However, if they are being trained it is more likely for them to touch it during the early part of their training to take into account that during this period the battery will drain faster. Either way, it is a good idea to keep in mind checking your battery from time to time to maintain a secure fence. You can test it by using a voltage meter.
You can already understand from their name how these fence chargers gain their power. This is the other type that you can use if you are looking for an electrical grid. The solar charger still draws its energy from a battery connected to it.
However, what separated it from the DC type is that it also has a solar panel. This panel can recharge the battery, which keeps it functioning non-stop. With this model, you don’t need multiple batteries, because you don’t need to swap them. This makes solar chargers great for temporary, rotational or strip grazing systems. This type of energizing is also lightweight, easy to transport. One downside, the device requires sunlight, otherwise, the battery won’t charge.
Acid batteries are really popular. They are used in solar fencers and typically last for around 3 years or approximately 1,000 days of charging. Some people do recommend having backup gel-cell solar batteries and trickle chargers to secure unbroken power for your fence. You can also take a look at some of the most powerful solar fence chargers, we’ve listed in our reviews.
What Size And Power Of Charger You’ll Need?
Note that the numbers given on each product are assumed in “perfect” conditions (set up precisely, with enough moisture in the ground, no weeds around the fence line, well insulated, etc.). However, keep in mind that no fence is ideal. It is really hard to install a fence perfectly. At the same time, the transfer of electricity from ground rods go through the ground is nowhere near perfect either.
- Joules is a unit of energy, which tells you the respective power of each energizer. The best way to use this number is to compare two products and decide, which one is more powerful. It isn’t likely for you to get a recommendation for a specific joule level. Keep in mind that Joules and Volts are two different things. For animal control, it’s not expected you to need more than 7,000 volts.
- Miles is a rating that helps you decide, which charger will work better for your length of the fence. You will need a bigger charger to maintain 7,000 volts through the entire length of your fence, the longer your fence line is.
- Acres is a unit which is suggested to not use when making your decision. This is because the distance of fencing around one acre can vary up to 60%, depending on how you set up the perimeter. Nevertheless, when you make quick estimates and comparing products, the approximate acreage can be helpful.
Choosing The Right Fence Charger
It is really important what type of fence charger you will buy because it is the soul of your fence system. Identifying the most suitable charger for this is equal to the succession of keeping your animals’ safe inside. To help with this decision you should consider the following things:
- Type of animal controlled. It is only natural if you have larger animals with thick hide, hair, hooves or foot pads, to require a stronger shock. Even more, if you have more aggressive animals such as bulls or stallions. If you manage to get an energizer chart where you can see the best electric fence charger for horses it will be of great help.
- The area to enclose. Give some thought of expanding your fence area in the near future, this will mean you will need a more powerful charger after some time. Usually, chargers will note their mileage rating, but acknowledge that this rating is for a single strand of steel wire with no weed around the fence.
- Powering your fence charger. The suggested type is usually AC-power. But as we’ve covered earlier, if you are in a remote location, you should take a look at DC or Solar-powered fence chargers. If you decide that the solar-type is the one for you, you will benefit of it charging its battery by the power of the sun.
- Type of net line. Polywire, rope or tape create more electrical resistance compared to steel wire. It is recommended to use a fence controller with less defiance if you have tape or poly rope. Also, note that the steel wire doesn’t have as much resistance as the aluminum one.
- The amount of fence wire strings. There’s a widespread principle when it comes to fences with numerous wires. You have to divide the fencer’s range rating by the total sum of string. After that select a charger with a mileage rating that meets those needs. Keep in mind to always increase power needs when adding more wires to your fence!
- The quantity of vines. We already suggested this, but the more shrubs that touch your net line, the further energy will be drawn from the fencer. In the case of light to heavy shrubs around your fence, it is recommended to have a net controller that has low opposition. They are able to maintain immerse electricity on the fence, despite some of it being drawn by plants.
So far the factors for finding the suitable fencer, we’ve highlighted have been things you can control. However, we have to note that there are also some environmental factors that aren’t up to our ability to change them. This may influence your decision, which charger you should buy:
- Poorly conductive soil. A poor conductor of electricity tends to be dry soil. It makes it harder for your charger to push energy through the ground to shock any animal that comes too close to the fence. To minimize this effect you can use a ground wire (usually there’s an extra center wire that runs along the fence but is instead connected to the ground terminal, not the positive one).
If you believe you may come across issues with grounding efficiency, you may want to take a look at a bit stronger energizer. This can help minimize any lost energy.
- Undergrowth and weeds around the fence. This is another really common problem in electric fencing. The undergrowth of weeds can develop into contact with the live wires at the base of your fence. Just like the first issue, this can also cause some drain in your charger. The effectiveness of your fence can reduce significantly over distance.
Of course to way to deal with this problem is to maintain a clean fence line, with no plants anywhere near it. However, this might not be the best way to spend your free time, so another way of helping with this problem would be buying a stronger charger.
- The amount of lines in your net. We already mentioned that some units come rated with a single or multiple wire distance rating. Naturally, when you add more wires you are extending the distance needed for the energy to be pushed along your fence line. If you keep an eye on the entire distance of border material you will power then you can calculate safely and fairly the distance rating you need (in this care single-wire). For instance, if you have a ½ mile of 8-wire fence, you would need energy for 4miles of fence material (8lines * ½ mile = 4 miles).
Installing Your Fence Charger
Usually, your fencer will come with a thorough set up handbook. Additionally, some of the individual components will have their own reference book to help you assemble it correctly. However, it’s good to know in advance what you will be getting yourself into. Here are the steps you have to follow.
When you install your energizer should be:
- Protected from the climate conditions (other than solar chargers). They can either be inside, preserved from any humidity or outside with an enclosure around it for protection. This is especially if the box of the charger isn’t waterproof.
- It should be near a source of 110-volt AC if this is the type you have. Otherwise, skip this step.
- You should close access to a ground rod system. This will be separate from a building or any grounding rods used by other systems or structures.
When you’ve finished with this, mount the energizer off the ground with a screw or a nail through the hanger hole in the charger’s case. Use an insulated ground wire to connect the ground wire to the ground terminal and ground rods. Thanks to a 20,000 volt (or higher) hook up wire, unify the fence terminal to the fence wire.
