The Gemi electric fence - 100% Made in Italy - is used to ward off wild animals such as wild boars, deer, foxes, etc.
The purpose of electric fences is to protect the territory from unsightly invasions. It is also used to contain animals such as cows, sheep, pigs etc.
It has nothing to do with hunting. We have all the legal certificates available to produce and sell electric fences. This is the only legal solution for those who want to protect their plantations.

Electric fence energisers
The energiser transforms mains or battery power into the high-voltage, low-current pulse that makes an electric fence effective. Since 1983, Gemi Elettronica has engineered its own electric fence energisers entirely in Italy, covering every power source — 230V mains, 12V battery and solar panel — so farmers and landowners always find the right output for their situation. Gemi's pre-sale technical team advises on energiser selection based on your fence perimeter, soil conductivity, vegetation contact level and the species to be contained or excluded, ensuring you specify the correct joule rating the first time.
Choosing the right energiser output
Output is measured in joules stored and kilometres of fence covered. A small vegetable garden protecting against rabbits needs a compact low-joule unit; a multi-hectare farm containing cattle or deterring wild boar requires a high-joule mains energiser with enough stored energy to drive current through wet vegetation in contact with the wire. Gemi's range scales from entry-level to professional across all power sources.
Mains, battery and solar energisers
The 230V mains models are the most powerful option for permanent installations with a nearby socket — low running cost, zero battery maintenance, continuous 24/7 output. The 12V battery models suit remote paddocks and rotational grazing, running for weeks on a standard car battery or indefinitely when paired with a Gemi solar panel. Combined mains and battery units switch automatically between power sources.
CE certified and factory guaranteed
Every Gemi energiser carries CE certification and a minimum 3-year manufacturer's guarantee. Short-circuit protection, lightning surge arrestors and weatherproof housings are standard across the range, ensuring reliable performance through British winters without manual intervention.

Questions and Answers
The electric fence for animals is neither dangerous for people nor for animals. As with everything, even for electric fences there is a standard that establishes the values to be respected.
The fence energiser is a product that emits intermittent pulses with a low amperage.
To create an electric fence for animals you need: a Gemi energiser - 100% Made in Italy - for fences that carries the current to the fence, an electrified conductor wire for the fence and insulators for electrified fences screwed on the posts to hold the wire.
With the current model we supply: grounding cable and cable with tweezers to be connected to the fence. With the dual power model, we provide a 220V power supply, cables for connections to the car battery (positive and negative), a grounding cable and a cable with tweezers to be connected to the fence.
Grounding is a fundamental thing for the functionality of the electric fence for animals, so it is recommended to do it correctly. To have the total discharge of current by the energiser, it is necessary to make the grounding by inserting 3 galvanized poles of 1 meter in the ground.
They must be positioned 3 meters apart, 80 cm in the wet ground and 20 cm outside, and then connect them with the yellow cable.
Together with the electric fence, we supply only 1 meter of cable that must be connected to the first pole. It is recommended to do it where there is the presence of vegetation, therefore a moist soil. Arid soil is not conductive. According to the tests carried out, placing 3 poles in any type of terrain, there will be no problem with functionality.
If you put only one stake, the power of the current felt will be less than its range and the animals will be able to cross the fence.
For a B12 energiser it is sufficient to use a 12V 40Ah car battery. The autonomy, if there is no dispersion in the electric fence, is about 10/12 days. Otherwise it lasts less.
If the current is far from the electric fence, for your Gemi energiser - 100% Made in Italy -, we have the high-voltage crossing cable that can work on the surface or underground, without discharging.
With this cable it is possible to carry current on the fence, without any dispersion.
The cable for electric fences can also be used to join two fences, then connect one end to a first fence and the other end to a second fence, when there is little distance between one fence and another.
To check if there is current on the electric fence for animals, just bring the tip of a screwdriver with an insulated handle a few mm away from the fence wire.
The moment you hear a ticking, it means that there is current on the electric fence.
An energiser cannot be outdoors. It must be kept indoors to prevent it from being damaged by bad weather.
An energizer cannot be kept outdoors. It must be kept indoors to prevent damage from the weather. In order to discharge all its current, it must be earthed by inserting 3 galvanized 1 meter stakes into the ground. They must be placed 3 m apart, 80 cm in the ground (wet) and 20 cm outside, and then connected with the yellow-green cable.
The device has a red positive cable at its output which is connected to the fence and a yellow-green cable which is connected to the first ground stake.
Never connect two electrifiers to the same wire, as the two impulses may cancel each other out, causing problems. You can connect two electrifiers to the same fence, but keep them on two separate lines of wire.
