The energiser is the heart of the electric fencing system and the best electric fence energisers for horses depend on your available power supply, the output required and the length of your fence. If you’ve got permanent electric fencing for horses and mains power nearby, a mains-powered energiser is the best option. A cable takes the power from the energiser to the fence – all you need to do is plug it in and switch it on. If your field is more remote and you don’t have access to mains, then a battery or solar energiser is your best option.
When selecting the best electric fence energisers for horses to meet your needs, it’s best to choose the most powerful energiser (highest Joules) you can afford for consistent power. And it’s best to err on the side of buying a more powerful unit than you initially think you need, keeping in mind that advertised power distances are based on ideal conditions and don’t account for vegetation reducing output. Calculate total fence length by multiplying the number of tape lines by the fence length (for example, a 1km fence with four tape lines is 4km of fencing).

Battery vs solar energisers
If you don’t have access to mains power, you’ll be choosing between a battery or solar-powered electric fence energisers for horses. Solar-powered energisers do have a battery, but this is charged by the sun rather than requiring you to replace the batteries.
Battery-powered electric fence energisers are a popular choice for strip grazing and temporary fencing as they are very portable. Some are powered by dry-cell 9V disposable batteries, so you will need to consider the cost of replacing them as they run out. Others are powered by rechargeable 12V batteries, which can power longer fences at a higher voltage. You could use a car battery, but a purpose-designed leisure battery is designed to give a steady output over time, while a car battery will dwindle quite quickly. The higher the Ah of the battery, the longer you can leave it between recharges.
Solar-powered energisers use energy from the sun to power your fencing setup. They tend to have a higher initial cost but are cheaper in the long run and assuming they’re in a good position to receive enough light, you don’t have to worry about making sure they’re charged.
How many Joules should an electric fence have for horses?
Electric fence energisers for horses work by delivering an electric shock to any horse that touches the fence the energiser is attached to. Joules represent the energy output of the energiser and put simply the higher the joules the stronger the shock will be.
It’s essential to strike a balance between effectiveness and safety, ensuring that the fence provides enough deterrent for the horses without causing harm.
The ideal number of Joules for an electric fence for horses can also vary depending on factors such as the size of the pasture, the behaviour of the horses, and the level or type of vegetation growth in the paddock.
However, generally, electric fences for horses typically have an output of around 0.5–1.5 Joules.
How many Volts should a horse fence be?
Voltage is a measure of the electric potential energy per unit charge between two points in an electric circuit. A higher voltage will provide a stronger shock, but it also relates to the distance over which the electric shock can effectively deter horses. Higher voltage levels typically allow the pulse energy to travel greater distances along the fence line.
The voltage of electric fencing used for horses should typically be between 2,000–10,000 volts to effectively deter horses.
The exact voltage required can vary based on factors such as the length of the fence, the type of insulators and conductors used, and the energy output of the electric fence energiser.
It’s also important that regular maintenance and testing of the fence system are carried out to ensure consistent voltage levels and proper functionality.
