Which Is the Correct Energiser for Me?

Choosing the right electric fence energiser is key to building an effective and reliable system. With several types available—including battery, mains, and solar options—it’s important to understand the differences so you can select the right one for your needs and environment.

12V Battery Energisers

Battery-powered energisers are ideal for locations without access to mains electricity. They are portable and well-suited to temporary or movable fencing setups such as strip grazing or seasonal rotation.

• High Power: A good choice for shorter fences or well-trained animals. These units use less energy, helping batteries last longer between charges.
• Extra-High Power: Better for longer runs of fencing or for animals that are more persistent. These models deliver stronger pulses and handle vegetation contact more effectively.

Battery energisers typically require regular recharging. In some cases, they can be paired with solar panels to extend operating time.

Mains-Powered Energisers

If your site has easy access to mains electricity, a mains-powered energiser is often the best long-term solution. They provide a consistent output and are virtually maintenance-free once installed.

• High Power: Suitable for small enclosures or where the fencing is primarily a psychological barrier.
• Extra-High Power: Ideal for large or complex fence systems, especially those with multiple lines or areas of high weed growth.

Mains units are generally the most reliable and require the least day-to-day attention, making them a strong choice for permanent installations.

Solar Energisers

Solar-powered energisers combine a small built-in battery with a solar panel to recharge during the day. They are a convenient and eco-friendly option, though they are typically less powerful than battery or mains models.

• Medium Power: Best suited to short fences or low-pressure situations, such as deterring small animals or enclosing very calm livestock.

Solar energisers are quick to set up and easy to relocate, but their performance can be affected by limited sunlight, especially during winter or in shaded areas.

What to Consider When Choosing

• Fence Length: Longer fences require more power to maintain effective voltage along the entire length.
• Type of Animal: Larger or more stubborn animals need a more powerful deterrent.
• Access to Power: Use mains power if available. If not, consider battery or solar depending on how remote or mobile your setup is.
• Vegetation Contact: Fences with regular contact from grass or weeds require stronger energisers to overcome energy loss to the ground.
• Portability: If your fence needs to move often, battery or solar options are better suited.

Each energiser type has its place, and the best choice depends on your setup. If you're still unsure, pop us an email and we'll point you in the right direction.
