Best Solar Fence Charger – A Buyer’s Guide

What is a solar fence charger?

A solar fence charger is the key component in a solar-powered electric fence system.

It is also called a solar energizer or solar fencer, and it belongs to one of the three main categories of fence chargers.

Solar fence chargers are rated based on their level of current output. This current is transmitted through a series of electric wires that form a grounded closed circuit.

This means that the fence system is grounded and its wire and fencer form a complete circuit.

This ensures that there is current always flowing through the uninsulated wires as long as the fencer is working, and these live wires can give an electric shock to any animal, person, or bird that comes in contact with it.

The amount of current flowing through the fencer system determines the degree of charge given. This can range from simple non-lethal shock to (potentially) fatal electrocution.

This way, the electric fence serves as a deterrent or barriers against encroachment by animals or people into a fenced-off area.

The different types of fence charger

Fence chargers are purposely built to generate electric current that flows through fence wires. There are different types, models, and brands of fence chargers, but they can be categorized into 3 the following categories based on their power source:

AC powered fencers 110-volts or 220-volts of AC power, and they can power 200 miles of electric fence wire; and this makes it suitable for permanent fence systems.

However, some farms are located in areas where linking up to the grid is difficult. In other words installing an AC-powered fence system isn’t practical.

Even so, such off-grid farms have 2 options to choose from; DC-powered fencers or solar-powered fencers. A DC-powered fencer system is a standard DC battery as both the power source as well as a store of electric energy.

This means that the battery needs to be recharged first before being used to power an electric fence.

Likewise, the duration that the battery can power the fence is determined by the total length of electric fence wire, with a longer wire length indicating a shorter battery life.

Still, the efficiency of a DC-powered fencer system can be greatly improved by connecting it to a solar charger which ensures that the battery is charged during the day when there is sunlight while the solar energy directly powers the electric fence.

During the night, the energy stored in the battery is used to power the electric fence. This type of fencer is called a solar-powered fencer system.

Features of the solar powered fence charger

Generally, solar-powered fencer systems are designed to be lightweight and portable, and hence can be moved around strip-grazing or rotational grazing systems.

Two critical components of these systems are the solar panels and the rechargeable batteries.

Usually, these batteries are lead-acid batteries whose average lifetime is 3 years, and they can store enough electric power, depending on their ampere-hour ratings, to power electric fence systems for 8 hours or more before requiring recharging.

Still, it is advisable for one to have gel-cell solar batteries as backups.

Power & Range

The efficacy of a solar-powered fencer system is determined by four main factors; overall fence length, number of electric wires in the fence, type of animal contained, and the impedance level.

A long fence that has multiple electric wires requires one to install a heavy-duty solar fencer as compared to a short fence with a few electric wires.

Also, large animals require lots of currents to be flowing through the wires as the lush hair and thick hides of such animals protect them from electrocution by low currents.

Impedance

The impedance of the solar fence charger is also important as it determines how much current flows through the wires, with low-impedance systems allowing more current to flow through the fence as compared to high-impedance systems.

This is important because overgrown weeds that touch the lowest electric wire in the fence literally serve as grounding mechanism for the fence, which effectively reduces the amount of current flowing down the fence lines.

For this reason, a low-impedance charger can generate enough current to power the entire electric fence despite the bottom-lying electric wires losing their power due to grounding via vegetations that are in direct contact with these wires.

Still, the solar fence charger needs to be grounded properly using ground rods for it to function well as grounding completes the circuit.


Best Solar Fence Chargers – The Reviews

Solar fence chargers can be rated according to their energy output, quality, impedance level, design quality, cost-performance ratio, and fence length that it can effectively power.

Using this rating criteria, 5 of the best solar fence chargers have been selected for review. Let’s take a look.

1. TOP PICK: Parmak Deluxe Field Solar-Pak 6 Fence Charger

Our top pick product is this low-impedance, battery-operated solar-powered fence charger from Parmak.

It features solid state circuitry and comes with a powerful solar panel as well as a built-in analog performance meter that allows one to monitor the state of fence electrification.

It is powered by a 6-volt battery that comes along with this product. This fence charger can generate up-to 1.6 joules of power; and a fence voltage of 9000 volts in an open circuit fence design or about 2650 volts in a closed-circuit open fence design whose electric wires have a combined resistance value of 500 ohms.

The DF-SP-LI Solar-Pak 6 is a compactly-designed, lightweight, and portable fence charger. It is 15 inches long and 9 inches thick, while its height is 18 inches.

This model is laser-trimmed and its weatherproof casing makes it suitable for outdoor installation.

Its large gray-colored casing features an attached red-colored cover whose bottom-side has two ports for power output and an on-off switch on its front side.

The solar panel is attached on top of the gray-colored casing, and the weatherproof design of the panel allows it to endure environmental insults as well as extremes of weather.

This model weighs about 17.2 pounds, which makes it quite portable, and the user can install it on any pole in the fence system.

This model is designed to capture solar energy and transduce (or convert) it efficiently into electric power that is then transmitted through the electric wires of the fence.

This energy-design model allows this solar fencer charger to exploit free and renewable solar energy to maximize the shock that flows the wires.

The solar panel of the DF-SP-LI Solar-Pak 6 features a state-of-the-art design that gives it an exceptional battery charging power, estimated to be 142 percent of the battery capacity of the 6-volt battery.

This battery is a heavy-duty, long-lasting store of electrical energy that can power the fence for 21-days if there is no sunlight.

Furthermore, the powerful solar panel can charge the battery during a cloudy day as the solar cells in the panel are quite sensitive and can convert even weak ultra-violet rays into electric power.

This model can generate large currents and voltages, and this attests to power and ingenuity of the design of its internal circuitry which allows low power input to generate a greatly amplified power output.

This is due to its solid-state circuitry whose design is laser-trimmed for precision.

This circuitry generates pulses of medium amperage shocks for a medium-time duration; and this makes it suitable for controlling short-haired livestock and pets, especially in areas where the vegetation cover is light.

Another important aspect of this circuitry is its impedance which is quite low, hence allowing this charger to effectively power a fence system whose electric wires are in contact with vegetation.

For convenience purposes, the inbuilt analog performance monitor allows the user to check on the status of electrification of the fence.

The Deluxe Field Solar-Pak 6 is built to power a 25-mile long electric fence. The 25-mile length is the total length of an electric wire that can be powered effectively by this charger.

This means that if the fence is made up of four electric wires enclosing the pasture, then the total length of all the four wires combined should not exceed 25 miles.

Therefore, people who have multiple-wire fences need to add up the total length of all the wires of the fence so as to know if this charger is suitable for them.

Regardless, the 25-mile length limit makes this charger suitable for powering a fence system that encloses a small or medium-size pasture.

Its power output also makes it suitable for powering a fence designed to keep out farm animals including cattle, dogs, pigs, and horses.

Even so, the material of the fence wires is important as they determine the overall electrical resistance of the fence.

Normally, steel wires are recommended because they have a low electrical resistance as compared to polywires, tape and ropes.

However, aluminum has a lower electrical resistance as compared to steel but an aluminum fence is quite expensive.

Regardless, the 25-mile rating for this solar energizer is based on performance achieved on fences with steel wires.

This model with a 24 months warranty that is guaranteed by Parker McCrory Manufacturing.

A unique aspect of this warranty is that it covers lightening-caused damages. The 6-volt battery that comes with this Solar-Pak 6 model is guaranteed by a 12-month warranty.
