If you own a ranch or have animals that need to be contained, an electric fence can provide an effective solution. It serves as a physical barrier that discourages livestock from wandering away while keeping potential predators at bay. To ensure the effectiveness and safety of your electric fence, there are crucial considerations to keep in mind: the fence charger and lightning protection. In this blog post, we will explore these considerations in more detail.

The Importance of a Fence Charger

The fence charger, also known as an energizer, is the heart of any electric fence. It is responsible for delivering the necessary electrical current to keep the fence active and effective. When choosing a fence charger, several factors should be taken into account:

Power Source

Fence chargers can be powered by either AC (alternating current) or DC (direct current). AC chargers are typically used when there is access to a continuous power supply, while DC chargers are more suitable for remote areas or locations without a reliable power source.

Voltage Output

The voltage output of a charger determines the strength of the shock that the animal receives when it comes into contact with the fence. The appropriate voltage should be selected based on the type and size of livestock being contained. It is essential to balance animal safety with an effective deterrent.

Battery Backup

In areas prone to power outages or remote locations, a charger with a battery backup is crucial. This ensures the fence remains active even when the primary power source is unavailable.

Lightning Protection for Electric Fences

Lightning strikes pose a significant threat to electric fences, as the surge of electricity can damage the charger and potentially harm livestock. Implementing proper lightning protection measures is crucial to safeguarding your fence and animals:

Lightning Arrestor

Installing a lightning arrestor in close proximity to the fence charger can help divert the lightning strike away from the charger. This device provides a path of least resistance for the electrical surge, preventing it from damaging the charger or other components.


Proper grounding is essential for effective lightning protection. Ensure that your fence system is adequately grounded, following manufacturer guidelines. Good grounding minimizes the risk of damage from lightning strikes and helps maintain a consistent electrical charge across the fence.

When installing an electric fence, selecting the right fence charger and implementing lightning protection measures are crucial for the overall effectiveness and safety of the system. Be sure to consider factors such as power source, voltage output, and battery backup when choosing a fence charger. Additionally, invest in lightning protection measures like lightning arrestors and proper grounding to ensure your electric fence remains operational and secure, providing the necessary containment for your livestock.

Remember, it's always recommended to consult with a professional fence contractor to ensure your electric fence meets local regulations and is installed correctly. By taking these considerations into account, you can have peace of mind knowing that your electric fence will be a reliable and safe solution for containing your animals.
