How many joules do I need to power a fence?
The standard suggestion is one joule for each mile of fencing. Bear in mind that the larger something is, the better it is, up until the point where induction takes place. When the voltage is sufficiently high, induction will power the gates and the neutral wire. How many joules do I need for a fence charger?
How much power does a fence charger use?
The average Zareba® fence charger consumes around 33 watts of power on a daily basis. The standard suggestion is one joule for each mile of fencing. Bear in mind that the larger something is, the better it is, up until the point where induction takes place. When the voltage is sufficiently high, induction will power the gates and the neutral wire.
What is a joule rating on a fence?
The Joule rating has become a standard in defining the power that can be transferred to a fence conductor from an electric fence charger or energizer, as they are sometimes called.
How many joules does it take to power a solar charger?
75 joules and usually less. Therefore, they are only designed to power a maximum of a few miles of wire. Generally, you will need about 10 watts of solar panel for each output joule of the energizer. Example: a 6 joule charger will need a minimum of a 60 watt solar panel. Click to see full answer.

How many acres is a Joule fence?
The Joule rating is best understood when combined with acres of fence. I.E. 1 Joule should be effective on 40 acres. However the user should understand that ground conditions, moisture, type of wire being charged and type of animals being contained are all factors that affect the success of an electric fence or whether the charger is strong enough ...
What is a joule in electrical?
The calculation of a Joule is a complicated electrical principle that defines the amount of electrical work being transferred (or work done).
What is a Joule rating?
The Joule rating has become a standard in defining the power that can be transferred to a fence conductor from an electric fence charger or energizer, as they are sometimes called.
Can you overcharge a fence?
There is one reality that can be relied on and that is; it is virtually impossible to overcharge a fence. So, for example, if you doubt that a 1 Joule charger will be strong enough spend a little more and buy a 2 Joule.
Can a high energy pulse cause electric shock?
The brief, high energy pulse cannot generate heat which is the damaging element of electric shock. Although the Joule Rating is the optimal measurement for today’s fence chargers it will be a difficult concept for many to understand as it requires an imagery that is created through experience.
What is an electric fence?
An electric fence circuit is between a battery and static electricity. It has higher voltage than the battery, yet usually less than static electricity. It has much higher energy potentials than static electricity yet less than that from a battery (which offers a constant flow, not in pulses).
How many volts is enough to kill an animal?
In fact, 600 volts may be enough (Remember, that animals have been killed by 220 volt circuits when touching alternating current, so, we know that 220 volts are enough to “open the door” to the passage of energy through flesh in optimum conditions.) At 5 p.m. the grass is dry, and so are the animals’ hooves and hair.
What is 88B energizer?
An 88B unit is an unusual energizer in terms of circuit design and function. Though only a 5.5 joule unit, even at low setting, the joules that it actually delivers to the point of animal contact greatly exceeds that of much larger units when the total fence circuit resistance is high.
How many volts is needed for sheep?
It has been stated that 3,000 volts is needed for sheep, 2,000 for cattle or variations on this theme. Such statements need to be read with much more understanding than is usually provided. The same sheep fence in my area in the early morning in June may read only 1,000 volts at 7 a.m. and 3,000 plus volts at 5 p.m. At both times, the fence is probably delivering effective energy and voltage to an animal.
How many volts is needed to open the door for energy to flow?
Thus the animals’ resistance to electrical flow has increased considerably, and more voltage is needed to open the door for energy to flow. Two thousand volts may indeed be needed to “open the door” for energy flow in this situation.
How long does a 100 amp battery last?
So, that 100 amp hours deep cycle battery should run the unit for 10 days ( 60,000 milli-amperes/6,000 milli-amperes per day).
Do energizers deliver higher energy levels?
Energizers also vary. Some deliver higher energy levels at lower voltages to an animal than other energizers. So the guidelines are just that – guidelines, but not scripture.
