Solar Fence Charger

Best Solar Fence Chargers Reviews

Animal and livestock keepers need an electric fence to control their animals. Electric fences create a barrier by producing a low and quick shock to the animal when touched. With time animals learn it is a barrier and keeps them confined within the fenced area. Property protection is another reason for having an electric fence to keep wild animals away from your home or animals.

Solar-powered electric fence chargers release the burden and stress caused by unreliable electric fences when there is a power blackout. Other areas with no power connection can still keep their animals safe with the use of the solar-powered electric fence charger. It has no installation cost since all you need is sunlight to make it operational.

In this article, we will discuss the best solar-powered fence chargers. What to look for, when buying a solar fence charger and the benefits of using solar chargers.

    Benefits of Using Electric Fence Charger

    Keeps animals safe

    The solar energizer allows the animals to be contained within the fenced area. This reduces damage to the fence and animals getting lost. To keep the charger operational, ensure it gets enough sunlight throughout the seasons. Moreover, solar-powered electric fences are a safer substitute for electric barbed fences that can kill animals.

    Protects nature

    Solar-powered fences protect gardens, plants, and trees from damages caused by animals. It is also safe for the environment since the energy source is the sun. Solar power does not emit harmful emissions to the environment, making it a clean source of power.

    Remote use

    People in areas where there is no supply of main power can use solar-powered fence chargers. They do not need any connection to the national grid. All you need is the solar power charger and transport it to anyplace. The sun is its only source of power.

    Easily accessible

    The product is available in the market. Visit your local farm store or hardware and purchase one.  Its services too can be accessed at any point of the farm, this is because you can easily move it from one place to another. If you do rotational grazing, you can move it as you rotate the animals.

    Easy to install

    The installation method of a solar electric charger is simple. Some of the fence chargers come with manuals on how to install and operate. With modern models, you can mount it at any angle provided it get exposed to sunlight.

    Battery life

    The fact that the charger sources its energy from the sun, one may tend to think that during winter or cloudy days, the fence charger will not work. This is not true, solar-powered fence chargers have a rechargeable battery that stores power. During the night or dull days, it continues working. The solar-powered fence can work for two to three weeks without sunlight.

    Things to Consider Before Purchasing a Solar-powered Electric Fence Charger

    Type of animals and voltage

    The type of animals you want to contain will determine the voltage required in the fence. Big animals like predators, moose, and deer will need a higher power like 4000-5000 volts.

    That will produce enough electric shock to keep them away. On the other hand animals like horses and cattle would require about 2000-3000 volt.

    Joules, a unit used to show the strength of the electric shock the animal will receive. The intensity of the shock and the damage it causes depends on the energy output dissipated in the animal's body. Hence the shock intensity will be determined by the voltage, time of the electric pulse, current, and the electric resistance of the animal’s body.

    The UL-69 or IEC 60335-2-76 is the standardization of fence charge to ensure it does not cause damage to the animal, the recommended fence charger shock should not exceed 5 joules.

    Look for the best fence charger for your animals. Remember that the fence is a psychological barrier and not to harm.

    Fence wire and weed conditions

    The open-circuit voltage condition is the voltage available in the fence when no vegetation or animal is in contact with the fence. The voltage is however reduced due to the weed conditions and the type of wire or rope used.

    Hence, reducing the effectiveness of the power in the fence. As you look for a suitable solar fence charger, be aware of the fence voltage that the manufacturer indicates in heavy, medium, and light conditions. Also, be informed about the variation in voltage when you use different types of fence wire.

    Range capacity

    Each solar-powered electric fence charger is designed to support a certain fence length. The manufacture usually indicates the length powered by the charger on the device. As you go out shopping, ensure you know the length of your fence wire.

    This will enable you to avoid a lower range capacity that will underperform or a higher range capacity that will cause harm than protecting the animals. This expression is used to calculate range capacity.

    Range capacity=number of wires. Fence length. 2

    Battery life

    This is a vital feature in every solar-powered fence charger. The battery life will tell you how long the battery will continue working at night or on cloudy days when there is no sunlight. Look for a fence charger with long battery life.


    The solar charger is an outdoor device and needs to cope with the changing weather conditions. It has to be durable, water, and weatherproof to fully functional.


    Low impedance means that the shock produced will only last for o.oo3 seconds or less. This is an energy-conserving measure as no power is lost on vegetation which is an issue with the high-impedance model. With a low impedance fence, chargers receive no current disruption caused by vegetation.


    All man-made things are susceptible to damage. That is why you need to look for warranty time. Any damages that occur within that time, will be addressed for free. Choose the one with a long grace period.


    Electric fences are always used to ensure safety whether for property, gardens, or animals. The availability of solar-powered electric fence chargers has improved in ensuring the safety of your animals.

    In line with the world’s vision of turning into clean energy sources, the solar-powered fence charger serves the purpose. As discussed above there are different types of solar electric fence chargers meant for various animals and purposes.

    You can way your options and find the best charger that suits your needs. The above list gives the best solar electric chargers to keep your livestock safe.
