How to Choose the Best Electric Fence Charger
Power Source
Electric fence chargers are powered either by electricity, battery power, or solar power.
– AC-Power
Fence chargers that are powered by an AC such as the Zareba Electric Fence Controller provide a constant source of power to your fence. All you have to do is plug the charger into a power source and you can relax knowing it is guarding your property 24/7.
– Battery-Power
For homesteaders who live in a remote location, an AC-powered charger may not be very convenient. If you cannot connect a charger to an AC mains outlet or you live off-the-grid, a battery-operated or a solar-powered charger is a smart solution for you.
Battery power is a safe and more affordable option as opposed to using electricity which can be expensive.
The only problem with a battery-powered fence charger is that the battery must always be charged up otherwise your fence will lose power quickly.
– Solar Power
Solar power is a cheap and clean source of energy and this type of charger produces good power for a fence around a smaller property. However, remember the solar panel has to be positioned where it can catch and store the sun’s rays.
Battery and solar-powered chargers may not provide the necessary electricity for a larger fenced property or deliver the extra zapping power that is required for large predators.
Joules
One of the most important factors to consider when buying an electric fence charger is its overall power which is measured in Joules.
– Smaller Properties
If you have a smaller property up to 40 acres or a 10-mile fence, and you raise chickens or care for baby goats, a charger with a low output of 0.1 or 0.10-joules will provide adequate power to deter small predators. This lower power output will also stop your animals from getting hurt from the electric shock.
– Larger Properties
If you own a large property with a 50 or 75-mile fence and you want to protect horses, cattle, and sheep from predators such as wild dogs, wolves, or bears, you will need an extra powerful 4.9 or 20-joule charger.
Although these extra-powerful chargers are very effective at deterring larger predators, they are not ideal for pet enclosures or chicken coops. A charger with a higher joule output can be dangerous for small animals. The electric current may not kill them but it can do substantial damage to their heart and nerves.
Fence Compatibility
The electric fence charger must meet the requirements of your electric fence.
Some chargers may be designed for a particular type of fence while other chargers can be used to power poly-wire, rope, or poly-tape fences. For example, if you have a galvanized chicken wire fence, you may have to use fiberglass ground rods as insulation against electric shocks.
Low Impedance Electric Fence Charger
There are a few factors that can cause a charger to lose power. Trees, shrubs, overgrown weeds, or wet vegetation can draw energy from the charger.
Depending on the charger’s overall design, a low-impedance charger will continue to deliver a powerful shock even if the fence has a lot of wet weeds or thick brush growing against it.
Color-coded Terminals and Handy Features
Color-coded controls, which include red and green dials or red and black dials, make it easier to set up and adjust your electric fence charger.
Some chargers have an LCD indicator light that pulses when the charger is working or even a bright LCD screen that displays the voltage such as the Parmak MARK8 Electric Fence Charger.
A battery indicator is another handy feature that lets you know when the battery is running out of juice.
