Which is the best Solar fence charger for you?

There are many great products listed above that protect your animals and land from small to large area coverage. 

They all may seem similar but they differ due to some factors such as:

Different Voltage and Animal types

The Most important Factor that must be considered when buying a solar fence charger is what type of animals you want to be sheltered inside an area.

Voltage requirements are varied across different animals according to their size.

Big animals such as deer, moose, or even predators need to be kept in 4000 to 5000 volts of electric shock.

However Cattle and horses etc can be kept within a 2000 to 3000 voltage fence wire

Power Output

Power produced by the solar fence chargers is measured in joules which is a unit of energy and represented in watts.

In electric fence chargers, Joules indicate the strength of the electric shock that animals will feel once they get in contact with the fence.

The intensity of shock and damage depends on the amount of power dissipation capability of each animal.

The shock received will depend on the voltage, current, time of electric pulse and electrical resistance of the animal’s body.

All the fence chargers follow a UL-69 or IEC 60335-2-76 standard that established that electrical pulse emitted by the charger should not occur less than one time per second.

The higher the joule output, stronger the electrical shock will be produced and the bigger the animal, more joules will be needed to create an electrical shock powerful enough to scare off animals but not harm them.

That is why it’s important to select Power output of a fence charger based on the animals you ll be keeping inside it and animals that are kept inside should recognize the fence as a barrier.


A customer trusts a product even more if it’s backed up by a hefty warranty.

If a manufacturer knows its product inside out and even after years of purchase still back their product up, it’s always a good sign.

Typical range of warranties in this list range from 1 to 3 years with different coverage options (Full to limited).

It’s always best to first select the product that fulfills your needs and if it has a good warranty included, it’s a huge bonus.

Variations in chargers

Manufacturers offer three types of solar fence chargers.

The first one is called a solid state charger that delivers a medium ampere shock in medium duration.

This is good for controlling livestock and cattle with less fur or hair as well as to be used in low weed conditions.

The second one is called a continuous output fence charger that provides a constant charge on the fence’s unlock pulses that other chargers provide.

This is a more power heavy option and also not as safe as other options.

The third option is the chargers that support low impedance charging that has a lower electrical resistance making more power flow through wire.

It’s best in any type of weed conditions and also optimizes the battery for longer use.


This is a crucial factor that must be checked before purchasing a solar fence charger.

Every Solar powered fence energizer has a limit to how much length of the fence it can power.

Range capacity of the charger is dependent on the circuit voltage of the device and estimated voltage drops that suffer throughout the length of the wire.

Another thing to consider while checking range is the material of the wire on the fence so it’s always best to check the material and its conduction properties before selecting a product with specific range.

Lastly each device has its own range and devices with lower ranges result in lower performance over large areas of fences.


Selecting a solar powered fence charger among all the choices is a difficult task and overwhelming at times.

But if you properly study your requirements and then check the available products in the market, you’ll have a much better time selecting a product that fits your needs.

Keeping both pros and cons of every product in mind, only then you will be able to compare and study your options well.

Reviews on the website are also vital in your decision making process

Lastly this is a matter of the security of your animals and going for cheap choices just to save a few dollars is not an advisable action.
