For remote pastures without power, the Parmak Solar-Pak 6 and Gallagher S40 are the best solar fence chargers. If you can plug in, the Patriot PE10 is ideal for poultry and small livestock, and the Zareba EAC50M-Z handles bigger animals and weedy fence lines.
An electric fence is only as good as its charger, also called an energizer. Too weak and animals learn to push through; too strong for a short poultry fence and you waste money and power.
We compared popular chargers on output in joules, rated fence length, power source, performance in weeds and which animals they suit, using maker specifications and long-term owner feedback.

The best electric fence chargers, reviewed
Best solar overall
Parmak Solar-Pak 6 (DF-SP-LI)
Best for: Cattle, horses and goats on pastures without power
Parmak’s Solar-Pak 6 is a long-standing favorite for remote paddocks. The built-in panel charges a 6-volt battery so the fence keeps working through the night and cloudy spells.
Mount it facing full sun and keep the panel clean. Like all solar chargers, it delivers the strongest shock when the battery is well charged.
What we like
- No mains power needed
- Proven, durable design
- Good range for small to medium farms
Keep in mind
- Needs direct sun for best output
- Battery eventually needs replacing
Best portable solar
Gallagher S40 Solar Energizer
Best for: Rotational grazing and temporary fences
The S40 is light and easy to move between paddocks, which makes it ideal for rotational grazing with polywire and step-in posts. A battery-saving mode helps it keep running during long stretches without sun.
It is not designed for very long permanent fences, but for portable setups it is hard to beat.
What we like
- Lightweight and portable
- Battery-saving mode for cloudy weather
- Simple, weather-resistant design
Keep in mind
- Lower output than mains chargers
- Not for heavy weed loads
Best for poultry
Patriot PE10
Best for: Chicken netting, small livestock and garden fences
For poultry netting around a coop or garden, you need a reliable pulse rather than raw power. The PE10 is a popular, affordable plug-in charger for exactly this job.
It also works well for keeping raccoons and foxes out of chicken runs when paired with poultry netting.
What we like
- Affordable and reliable
- Right output for poultry netting
- Easy setup
Keep in mind
- Not powerful enough for large livestock
- Needs an outdoor-rated power source
Best for large livestock
Zareba EAC50M-Z
Best for: Cattle, horses and predator control on long fence lines
Low-impedance chargers like this one keep a strong shock even when weeds touch the wire, which matters on long permanent fences around cattle or horses.
It is also a solid choice if you need to deter larger predators from a homestead.
What we like
- Strong low-impedance output
- Handles weedy fence lines
- Good for large animals
Keep in mind
- Overkill for a small poultry fence
- Requires mains power
How to choose an electric fence charger
1. Match the charger to your animals
Poultry, sheep and goats need a reliable shock on netting or many close strands. Cattle and horses need fewer strands but a strong, consistent pulse. Predator control usually needs higher output.
2. Look at joules, not just miles
Rated miles are measured in ideal conditions. Output in joules is a better guide to how well a charger copes with weeds, long fences and thick-coated animals. Many farmers suggest buying more power than the rated length suggests.
3. Solar or plug-in?
Plug-in chargers are cheaper to run and more powerful. Solar chargers are the only option far from power and are perfect for portable or rotational fences.
4. Never skip grounding
Most fence problems come from poor grounding, not a weak charger. Use the number of ground rods your charger maker recommends, spaced apart, in moist soil.
- Install recommended ground rods
- Keep weeds off the bottom wire
- Test the fence with a voltmeter weekly
- Use warning signs where people walk
NovaAgri tip: Buy a simple digital fence tester with your charger. It takes seconds to find a fault before animals do.
Frequently asked questions
How many joules do I need for an electric fence?
Small poultry and garden fences work well around 0.1 to 0.5 joules. Larger livestock fences and weedy lines generally need 1 joule or more. Check the charger maker’s guidance for your animals and fence length.
Are solar fence chargers any good?
Yes, especially for remote or portable fences. They need full sun and a healthy battery to give their best output.
Will an electric fence keep predators away from chickens?
Electric poultry netting with a suitable charger is one of the most effective ways to keep foxes, raccoons and dogs away from a flock.
Why is my electric fence not shocking?
The most common causes are poor grounding, weeds touching the wire, broken insulators or a flat battery on solar chargers.
Is an electric fence safe for animals and children?
Properly installed fences using approved chargers deliver short pulses designed to deter, not injure. Always follow the maker’s instructions and add warning signs.
Final verdict
Choose the Parmak Solar-Pak 6 or Gallagher S40 for off-grid pastures, the Patriot PE10 for poultry netting, and the Zareba EAC50M-Z for large livestock on long fence lines.
