1. How do Power Wizard fence energizers work?
Power Wizard Fence Energizers create a high voltage pulse of electrical energy on a fence line every 1 to 2 seconds. In ideal conditions, the fence energizer, hot wire and ground wire form an incomplete circuit. When an animal touches the hot wire (and ground return wire, if installed), it completes the circuit and receives a shock. The severity of this shock is determined by the capacity of the fence energizer and the condition of the fence line and ground system. This creates a psychological barrier that can be used to keep animals in or predators out.


2. What power sources do Power Wizard fence energizers use?
There are three types of Power Wizard Fence Energizers. AC-powered fence energizers simply plug into a standard 110V outlet. They are the most effective and practical type of fence energizer and are available in a wide selection of joule ratings. Solar-powered fence energizers are used in remote areas without access to AC power. An attached solar panel charges a battery which powers the fence energizer. These require 4 to 6 hours of sunlight per day. DC-powered fence energizers use D-cell batteries or 12V batteries and are designed for use in temporary applications.


3. Which fence energizer should you choose?
The fence energizer is the most important component of your electric fence system.  After you determine your power source, selection will depend upon a variety of factors, including overall fence length, acreage, terrain, ground condition and the animal being controlled.

  • Fence length/acreage – Because different animals require different fence configurations, it is typically easier to choose a fence energizer based on acreage instead of overall fence length.  For example, cattle may only require two rows of fence wire while deer may require five rows, increasing the length of fence wire needed.
  • Expansion – If you think your pasture, food plot or garden may expand in the future, you may want to consider a more powerful fence energizer.
  • Terrain – Weeds and vegetation affect the ability of a fence energizer to deliver an effective shock.  Low Impedance fence energizers are designed for use in average conditions with moderate weeds and vegetation.  Choose an Ultra Low Impedance fence energizer when the fence will be exposed to heavy weeds and vegetation.
  • Animals – Larger animals with tougher hides require a more powerful fence energizer to deliver an effective shock.

4. What are joules?
A joule is a basic measurement of energy which represents the amount of shocking power delivered to an animal. Joules, not volts, are considered to be the most accurate measurement of power in a fence energizer. This is because fence and ground conditions have an effect on voltage readings throughout the fence line.


5. What is the difference between Low Impedance and Ultra Low Impedance?
Low Impedance fence energizers are designed for average fence conditions, as shock power will decrease when the fence is exposed to heavy weeds and other vegetation. Ultra Low Impedance fence energizers will maintain shock power in these conditions.

6. Do you need to use ground rods?
The ground system is a crucial component of the electric fence system. It consists of at least three highly conductive rods driven into the soil and then connected to the ground terminal of the fence energizer. This collects the electrons needed from the soil to deliver an effective shock. This system should be installed in soil that is consistently moist because dry soils do not conduct electricity well. Ground rods should be made of galvanized steel and be at least ½" in diameter and 6'L. For sandy or dry soils, or where the ground is frozen or snow covered, a ground return wire may be required as well. In this case, the animal would need to contact the ground return wire and a hot wire to receive an effective shock, instead of contacting just a hot wire.


7. What is the difference between the ground wire and ground return wire?
The ground wire goes from the grounding rods to the ground terminal on the fence energizer. This wire should be 10 to 14-ga. insulated wire rated at 20,000 volts. A ground return wire is part of the fence line and is used in areas with poor grounding conditions such as dry, sandy or frozen soils. The animal must contact both a hot wire and the ground return wire to receive a shock.


8. Can a Power Wizard fence energizer be used on barbed wire?
No. This should never be done.


9. Can more than one fence energizer be used on a fence?
No. This will damage the fence energizers and void the warranty.

It is also dangerous because it will reduce the time off between pulses of energy on the fence.


10. What kind of battery should be used with a 12V fence energizer?
Use at least a 60 amp hour or greater deep cycle rechargeable battery.
