What Should You Look For in Solar Fence Chargers?

Just as with any important purchase, it is essential to do your research and consider which brand of product has exactly the qualities that will fit your needs. Before purchasing a solar fence charger, it is important to take a step back and evaluate your current property and solar fencing needs.

Here we have developed a list of five important criteria that every person should consider before purchasing a solar fence charger. Finding a fence charger that fits your property and animals’ specific needs will allow you to get the very best out of your purchase.


Before shopping for a solar electric fence charger, it is imperative to carefully measure the extent of your property. This will allow you to determine the correct range capacity for the solar-powered electric fence charger you choose.

Once you have measured the extent of your property, you can insert your measurements into a simple equation that will determine the exact range rating you should look for in your new fence charger. Simply multiply the total length of your fence by the number of wires found in your electric fence. Then multiply this by two to get your recommended range rating.


The voltage of a solar-powered fence charger refers to the strength of the shock that is given upon contact. Purchasing a fence charger with a voltage that is too low for the size of animals that are on your property could result in danger for your animals through escape or the presence of predators.

Type of Animals Involved

Next, consider the size and type of animals that you keep on your land as well as the type of animals you want to keep off of your property.

To keep your animals and property safe, you need to purchase an electric fence system that will give off a large enough shock to properly frighten the animal without harming it.

For most cattle and horses, a voltage of about 2,000 to 3,000 will be successful in protecting without inflicting harm.

However, to protect your livestock from outside threats such as bears or cougars a much more significant shock is required, ranging anywhere from 4,000-5,000 volts.


The best solar electric fence charger will come equipped with a battery that will automatically turn on when not enough sunlight has been given to produce a full charge.

As a farmer or rancher, you never want to have to worry about the failure of your electric fence or have the stress of constantly monitoring weather conditions. The presence of a battery will give you the peace of mind you need that your fence will perform well even on cloudy or overcast days.


The number of joules that your solar fence charger holds will determine the length of shock that is given upon contact. The higher number of joules that a fence charger possesses will result in a longer and stronger shock.

Again, consider the type of animals you are protecting when you determine joule number and shock strength. For smaller animals such as goats or sheep, your fences’ joule number should be relatively small whereas, for larger animals such as horses or cattle, your joule number should be higher.

Safety should always be your priority, so make sure that you are buying a solar electric fence charger with a joule number that is appropriate for your animals.

Here’s How We’ve Determined the Best Solar Fence Chargers

To determine the best solar fence chargers, we measured the specs of the top products on the market against our listed criteria to see how they held up and if they’re worth buying. We then checked reviews from verified customers to gain feedback on the dependability and overall quality of each product.

And without further ado, here is our list – tailored to your specific needs – of the best solar fence chargers. 

#1: Parmak Magnum Solar Pak (Best Value – All-Purpose)

Replace Image below with Amazon SiteStripe Image

The Parmak Magnum Solar Pak is our choice for the best all-purpose solar-powered electric fence charger, and selling as an excellent value, it is a great choice for any buyer looking to protect a significantly large piece of land.

The Parmak Magnum covers up to 30 miles and includes a 12-volt battery to ensure maximum shock power all through the night and even on cloudy days, making it a great choice for buyers with limited seasonal light availability. It can also keep a single charge for up to two weeks.

This solar fence charger also includes low impedance technology which means that it can provide an ample amount of shock even in the presence of foreign objects such as vegetation or round wood posts. The Parmak Magnum Solar Pak can deliver shock through any of these foreign objects.

This Solar Pak also contains up to 3.1 joules of shock power which means it is ideal for large animals such as horses or cattle.

The manufacturer proves the overall quality of their solar fence charger by offering customers a 3-year warranty as well as a 2-year warranty for lightning. So, you can be fully assured of the quality of this product.

The only downside to this unit is that several customers left negative reviews about this solar fence charger’s ability to withstand extreme cold weather conditions. So this charger may not be the best choice for those who are exposed to extreme cold or winter conditions.

#2: Gallagher S200 (Best Overall Solar Fence Charger)

The Gallagher solar fence charger is truly the best of the best when it comes to reliability and longevity. This particular brand is known for complete excellence in all of its products and is thoroughly trusted by farmers and ranchers alike.

The Gallagher S200 covered up to a 45 miles land radius making it an excellent choice for large spaces. This Gallagher solar fence charger also comes in an S400 model which will cover up to 60 miles of acreage.

If you have a higher budget and want to invest in an electric fence energizer that will meet all of your land maintenance and protection needs, the Gallagher is the way to go and our top two reasons below will explain why.

Battery Life

The battery life of the S200 is exceptional. This solar fence charger comes equipped with two, 12-volt batteries that have the capacity to provide up to 1 week of full power without sunlight.

The battery system also includes an LED indicator light to indicate battery life and whether a charge will be required soon.

Panel Design

The solar panel of the Gallagher S200 is uniquely designed to truly harness the full impact of the sun. This solar electric fence charger features a split solar panel design to promote maximum sunlight exposure from all different angles. This split design also ensures that the sun’s energy will be captured fully, even in the presence of unforeseen circumstances such as excessive dirt buildup or foliage.

The solar panel itself is also fully adjustable, making it a very portable fence charger. This is great for landowners that deal with moving sunlight as the solar panel features a 360-degree mount to promote optimal sunlight exposure.

The Gallagher S200 also comes with a free lightning diverter which will keep your fence charger protected during even the harshest of weather conditions. This unit has been tested and approved to withstand varying degrees of extreme weather from extreme cold to extreme heat.

Overall, the Gallagher S200 (or any in this particular series) would be a great fit for landowners looking to provide optimal protection to their land and livestock. It is important to note, however, that this series in particular is significantly more expensive than our other choices.

While there are several less expensive options, these other choices may not hold the same degree of reliability and longevity as the Gallagher does.

#3: Parmak DF-SP-LI Solar (Best for Small Parcels of Land)

Replace Image below with Amazon SiteStripe Image

The Parmak DF-SP-LI Solar Panel Fence Charger is our top choice for use on small farms and with small animals.

This Parmak can cover up to a 25-mile range and features a 3-year warranty. Parmak stands behind their products in every situation, and they are always ready and able to assist their customers.

The DF-SP-LI solar fence charger comes equipped with an easy-to-use, built-in performance meter and monitoring system that measures the extent of your solar battery charge performs a comprehensive meter test, as well as a voltage output test. All of these features help to ensure that your fence energizer is working at optimal performance.

This low impedance technology charger also delivers a strong and steady shock through all types of materials including wet foliage. It gives up to 9000 volts of adjustable shocking power.

This unit is highly recommended by farmers and landowners around the world. It is also very reasonably priced. The only downside to this particular unit is that, even though it is ideal for a small piece of land, it will not be able to accommodate any land expansion, which means you will be fairly limited in the range capacity it can offer.

#4: Zareba ESP10M-Z (Best Low Cost)

When comes to the cost of solar electric fence chargers, the price is most often determined by the amount of land that the solar charger can accommodate.

For instance, a solar fence charger that can charge fencing for up to 60 miles will be significantly more expensive than one that can charge a fence for up to 25 miles. This means that there is really not a definitively “low cost” option. It all really just depends on what your specific needs are.

Here we are looking closely at a unit that is designed for relatively small farms. This unit covers fencing for land up to 10 miles.

The Zareba works compatibility with both steel wire and poly wire fencing, however, it is important to note that, when used with poly wire fencing, the range capacity drops down to a 5-mile radius.

To obtain the complete range capacity of this unit, the land it is covering must also be virtually weedless. Even though this solar power fence charger does feature low impedance technology, it does not compare to the quality that our other low impedance chargers held.

With direct sunlight exposure, the Zareba fence charger can capture a full battery charge in just three days, and it has the ability to keep its charge for up to two weeks. Shocking at up to 0.15 joules, it is a unit that can be used on larger animals as well.

This unit also comes equipped with a simple indicator light that shows whether your fence is charged or not. This is the extent of its maintenance information, however, which differs greatly from the high-quality monitoring systems of some of our other choices, such as the Parmak.

Customers praised the Zareba for its ease in installation as well as its 1-year warranty. Overall, while this unit has some great qualities that would work well for a small piece of land, the lower price does mean that it lacks some of the more impressive amenities that our more expensive options have.

This all just comes down to your preferences and needs. If you are looking for a less expensive solar fence charger that will get the job done without having all of the fancy operating systems and technology, the Zareba may be just the right choice for you.

#5: Fi-Shock ESP2M-FS (Best Protection for Pets)

Replace Image below with Amazon SiteStripe Image

If you own pets, most likely one of your greatest fears is losing your beloved pet by having them escape your yard and run away. Having a fence protects your pets from outside dangers such as roads, cars, and animal predators.

While having a wooden fence is a great option, there are many pets such as larger dogs and cats that can easily climb, jump over, or dig under fences which leads to escape.

A solar electric fence charger made specifically for the protection of small domestic animals like your pets can give you the peace of mind you need in knowing that your fur baby will be safe from danger and harm. These also hold the bonus of keeping pest creatures such as rabbits, opossums, or raccoons out of your yard and away from your pets and your gardens.

The Fi-Shock, portable solar fence charger is made specifically for the protection of animals such as dogs, cats, rabbits, poultry, and other small domestic animals. Providing up to 0.04 joules of shock power, this solar fence charger is made to be perfectly safe for small animals.

Much like the way an electric dog fence and collar system works, the Fi-Shock delivers a very small shock to your animals warning them to stay away from the fence line.

The Fi-Shock is a very versatile solar fence energizer, meaning that it is compatible with a variety of different fence wires including, poly rope, poly tape, poly wire, steel fence, and aluminum fence.

This solar fence charger covers up to a 2-mile radius and includes low impedance technology which allows it to deliver shock through various types of weeds and vegetation. This unit also comes with a 1-year lightning guarantee.

This unit will not contain the same power or shock capacity as our other units mentioned above, but that is because it is made for small domestic animals only, so keep this in mind when you are purchasing. This solar fence charger will not be able to protect larger animals such as horses and cattle.

What about the Cheapies? Our Best Budget Products

 There are several affordable solar fence charger options on the market today. While these options will not come with as much of the high-end technology that our other options do, they will certainly get the job done.

Here we have included three budget-friendly, solar charger options for you to review, one for each range capacities varying from small to medium to large.

#1 Budget: Patriot PS5 – 2-Mile Range

Replace Image below with Amazon SiteStripe Image

The Patriot PS5 is an excellent electric fence charger that can protect up to 2 miles of land. With low impedance technology, you will be assured that this unit will provide a consistent level of shock across several commonly-found barriers such as foliage.

The PS5 features a 4-volt battery and a 2-watt solar panel that is suitable for all-year use in various levels of weather conditions from cold to warm climates. It also comes with a 1-year manufacturer warranty.

This solar fence charger provides a shock of up to 0.05 joules which is important to consider when looking to purchase this product. While it has been proven to protect larger animals such as horses and cattle, it is not strong enough to keep your most strong and independent animal safe. Larger animals may not be as affected by this shock as some of our other stronger units.

#2 Budget: Zareba EDC15M-Z – 15-Mile Radius

Replace Image below with Amazon SiteStripe Image

The Zareba EDC15M is a great, low-cost solar fencing option that is ideal for large pieces of land ranging up to 15 miles. This solar fence charger is compatible with all types of fencing and can easily shock through heavy weed and foliage presence due to its excellent low impedance technology system.

Its 12-volt battery features a 25% longer battery life than that of several other brands, and the entire unit has been proven to be completely weather resistant.

An indicator light clearly shows whether the unit is charged or not, and the manufacturer backs their product with a 1-year lightning warranty.

This solar fence charger is a great choice for farm owners that have a large range of land and a variety of different animals to protect including horses, cows, pigs, and even pets. It is a very versatile unit.

Frequently Asked Questions

Do solar fence chargers work?

The answer is yes! Because solar technology is still a relatively new discovery, some people remain leery of its credibility. However, when it comes to solar fence chargers, the top manufacturers and brands have provided proven results and great success for a variety of different customers.

Solar fence chargers harness the power and energy of sunlight to provide power to an electric fence. Unlike basic electricity, sunlight is always present in one way or another. Solar fence chargers are designed to capture power from the sun on clear days and store that power so that electric fences can be charged throughout the nighttime hours and on overcast days.
With a solar electric fence charger, you will also never have to stress about power outages due to storms or heavy winds. Your solar fence charger will continue working perfectly through a power outage, and your land and animals will be kept protected.

All solar fence chargers also come equipped with a backup battery which means if your unit is completely drained of solar power, your battery will kick in to provide power.

Solar fence chargers are also extremely cost-effective. By using the power of the sun, which is completely free, you are reducing your purchased energy usage and cost and thus saving money in the long run.

How long do solar fence chargers last?

Solar fence chargers are made to be extremely durable, and they have extreme longevity. Because these units are mounted outdoors, they are made to be completely weatherproof and most can withstand harsh conditions such as extreme cold and heat.

Because of how well solar fence chargers are constructed, many of them can last a very significant amount of time. Without extreme damage, such as having the panel break off, these units can last quite a long time.

It is important to maintain your charger’s battery by replacing it about every 3-4 years. However, beyond that, there is not much maintenance that is required for a solar fence charger.

Overall, these chargers are an excellent and very cost-effective option for landowners wanting to save time and money in the long term. While solar fence chargers will cost more up front than a standard electric charger, in the long-term they will be well worth the higher price tag in energy cost savings.

What is the best fencing material to use with a solar fence charger?

Solar electric fence chargers are compatible with a variety of different fencing materials including standard fence wire, single wire fence, steel wire, aluminum wire, poly wire, rope, or tape.

While all of these options will work and get your electric fence charged, certain materials are better at transferring energy thus helping you get the very most out of your charger, making it the perfect solar fence charger for your property.

It is generally agreed that steel or aluminum wire is the most conducive type of wiring for solar charging unit success. This is because these materials will create less energy resistance than other materials such a poly wire. This will, in turn, allow for an easy transfer of power and energy which protects against premature battery drain.

Why does the best solar fence charger have a UL list rating?

Almost every electrical product on the market today is made following several safety guidelines to prevent shock and other hazardous conditions. However, because electric fences are designed to deliver a shock, they require their own set of safety standards and ratings for the United States and Canada.

In the United States, the Underwriter’s Laboratory (UL) is responsible for ensuring the safe and effective practice of electric fences and their chargers, whether they be electric or solar.

Before a solar fence charger is placed on the market, it should be thoroughly tested and completely approved by UL to ensure the safest performance and effectiveness of the product.

Because of the hazards associated with electric fences and the fact that shocking will be required to protect the health and well-being of your animals and property, it is imperative that you purchase an electric fence charger that has been UL tested and approved. This will give you the peace of mind you deserve in knowing that you, your livestock, and your property will be protected safely and dependably.

Even though most solar fence chargers on the market today have been UL tested and approved, several solar fence chargers have not received the UL stamp of approval. These typically come from smaller manufacturers that develop a more affordable solar fence energizer. Several may have had independent testing performed or manufacturer testing. While this does not necessarily mean that the product is unsafe, it is very important to thoroughly research the safety of your product before purchasing.

Overall, while it is a personal decision to be made by the buyer, as a general rule of thumb, it is recommended to find a solar fence charger that has been UL tested and approved. These options will likely be more expensive. However, your safety and the safety of your animals and property are well worth the extra expense.
