Choosing the Right Electric Fence Charger: Understanding Joules and Their Importance

An electric fence charger is the heart of your electric fence system, providing the power needed to deter animals and protect your property. One of the most important factors in choosing the right fence charger is determining how many joules it needs to have to be effective.

To understand the role of joules in an electric fence, it's helpful to think of joules as the unit of energy that is delivered to the fence with each pulse. The more joules a fence charger delivers, the stronger the shock it provides to any animal that touches the fence.

So, how many joules does an electric fence charger need to be effective? This will depend on a number of factors, including the size of your property, the type of animals you're trying to deter, and the type of fence you have.

For small properties with light fencing and small animals, a charger with 1-2 joules of output may be sufficient. For larger properties with heavy-duty fencing and larger animals, you may need a charger with 3-5 joules of output or more.

It's also important to consider the type of fence you have. High-tensile, polywire, and polytape fences require less joules than traditional steel-wire fences because they are lighter and have less resistance.

When choosing a fence charger, be sure to read the manufacturer's specifications carefully. Some chargers are designed for specific types of fences, so be sure to choose a charger that is compatible with your fence.

In conclusion, the number of joules a fence charger needs to effectively power an electric fence will depend on several factors, including the size of your property, the type of animals you're trying to deter, and the type of fence you have. Be sure to choose a charger with enough joules to meet your needs and read the manufacturer's specifications carefully to ensure compatibility with your fence.

I have a small vegetable garden (about 400 square feet). Animals such as squirelles and rabbits destroy my raised bedes each year, eat the vegies, dig the soil and expose the rootes of my plants which die later. I put animal repellent granuals once a week in the last 4 years around the raised beds; unfortunately it did not help. I put a 4 feet high chicken mesh wire fence around my vegie beds this year, they also did not help. Some body told me that I should put a 1/2 inch mesh, 4 feet tall, 19 or 20 gauge galvanized steel wire around the raised beds and connect this wire fence to a solar powered electric generator. So, I am going to try it next year. I am a retired old man and gardening is the only hobby that I have. I would appreciate if you could help me with myanimal problems and guide me as how to proceed. I have the following questions:
- What kind of a solar charger do I need for to cover a 400 square feet?
- What should be the appropriate joule output of the charger?
- Does a solar energizer work with a galvanized chicken wire fence? I read that the chicken wire fence can conduct the electricity generated by the a solar charger – Is it true.
To make it short, please let me know if the solar charger and chicken wire fence would be an effective way to get rid of the squirells and rabbits. If yes, what Solar Charger within a price range of 150-250 dollars would you recommend? I have already found the galvanized wire fence. Thank you for your response in advance.
Sincerely yours

Hello, do you have a plugin fence charger that will work on 220VAC power? The charger will be used on a Eurosizer hot-walker to electrify six panels so a total of about 36 feet of fence.
