Complete Electric Fence System Buying Guide
Everything you need to confidently choose, install, and maintain an electric fence system — from electric netting to energizers.
What Is an Electric Fence System?
An electric fence system is a psychological and physical barrier that uses low-impedance electrical pulses to deter animals from breaching a boundary. Unlike traditional barbed wire or wooden fencing, electric systems are lightweight, fast to install, and highly adaptable — making them the preferred choice for modern livestock farmers, homesteaders, and pasture managers worldwide.
A complete electric fence system consists of three core components:
Energizer (Charger)
The brain of the system — converts mains, battery, or solar power into safe, high-voltage pulses every second.
Conductive Fencing
Electric netting or wire/tape that carries the pulse around the perimeter of your paddock or pasture.
Earth Grounding
Grounding stakes that complete the circuit when an animal touches the fence — critical for the system to work.
Types of Electric Fencing
Choosing the right type of electric fencing starts with understanding what's available. Each type is designed for different terrain, animal species, and management styles.
Electric Netting (Poly Net)
Electric netting is a prefabricated mesh that integrates conductive strands into vertical and horizontal lines. It's the fastest portable fencing solution available. A 164-foot (50m) roll can be set up in under 20 minutes by a single person. Popular for poultry, sheep, goats, and even predator exclusion around vegetable gardens.
Electric Wire & Tape
Traditional electric wire (poly wire, poly tape, or high-tensile wire) is strung between posts at defined heights. It's more economical for large perimeters, permanent installations, and cattle or horse fencing where tall, spaced strands are more appropriate than a solid mesh.
Electric Rope & Braid
Thicker and more visible than wire, rope and braid are ideal for horse paddocks, temporary rotational setups, and any situation where high visibility reduces animal stress and jumping incidents.
| Type | Best For | Portability | Cost per Metre | Visibility |
|---|---|---|---|---|
| Electric Netting | Poultry, sheep, goats, rabbits | ⭐⭐⭐⭐⭐ | $$ | High |
| Poly Tape (20–40mm) | Horses, temporary paddocks | ⭐⭐⭐⭐ | $ | Very High |
| Poly Wire | Cattle, rotational grazing | ⭐⭐⭐⭐ | $ | Medium |
| High-Tensile Wire | Large-scale permanent perimeters | ⭐ | $$ | Low |
| Rope / Braid | Horses, hobby farms | ⭐⭐⭐ | $$$ | Very High |
Electric Netting vs. Electric Fencing: Which Do You Need?
This is the most common question new buyers ask. The answer comes down to your primary livestock and how you manage your land.
| Feature | Electric Netting | Electric Fencing (Wire/Tape) |
|---|---|---|
| Setup time | ✔ Very fast (15–25 min) | Moderate (30–60 min) |
| Predator control | ✔ Excellent | ✘ Minimal |
| Small animal containment | ✔ Yes (chickens, rabbits) | ✘ No |
| Large animal containment | Good | ✔ Excellent |
| Rotational grazing | ✔ Ideal | ✔ Ideal |
| Long-run cost | Moderate | ✔ Lower per metre |
| Terrain adaptability | ✔ Very flexible | Moderate |
| Visibility for animals | ✔ High | Low–Medium |
How to Choose the Right Electric Fence Energizer
Your energizer — also called a fence charger or controller — is the most critical purchase in your electric fence system. Getting it wrong is the number-one reason fences fail to work.
Power Source: Mains, Battery, or Solar?
Mains-Powered
Most powerful and consistent. Best for permanent installations within reach of an AC outlet. Never runs out of charge.
Battery-Powered
Flexible for remote paddocks. Typically runs on 6V or 12V batteries. Requires regular monitoring and recharging.
Solar-Powered
The ideal off-grid solution. Low maintenance once installed. Works well in regions with adequate sunlight year-round.
Joule Output: Don't Undersize
Energizers are rated by their stored joules (energy capacity) and output joules (what actually reaches the fence line). Output joules are the number that matters. A common rule of thumb:
| Output Joules | Recommended Use Case | Max Fence Length |
|---|---|---|
| 0.1 – 0.5 J | Small pets, garden protection | Up to 1.5 km |
| 0.5 – 1.5 J | Sheep, goats, small paddocks | Up to 5 km |
| 1.5 – 3 J | Cattle, horses, medium farms | Up to 15 km |
| 3 – 6 J | Large cattle operations, deer | Up to 40 km |
| 6 J+ | Commercial, large perimeters | 80 km+ |
Always oversize slightly. Vegetation contact, moisture, and long fence runs all reduce effective voltage. An undersized energizer is the most common reason farmers find livestock have escaped.

Which Electric Fence System Works Best by Animal Type?
| Animal | Recommended System | Min. Fence Height | Min. Output Joules | Notes |
|---|---|---|---|---|
| 🐔 Poultry | Electric Netting | 91 cm (36") | 0.25 J | Critical for predator exclusion |
| 🐑 Sheep | Netting or 3–4 wire | 90 cm | 0.5 J | Wool reduces conductivity — higher voltage needed |
| 🐐 Goats | Netting preferred | 100 cm | 1 J | Goats test fences relentlessly |
| 🐄 Cattle | Wire or tape, 2–3 strands | 100–120 cm | 1.5–3 J | Thick hides require strong pulse |
| 🐎 Horses | Wide tape or rope | 120–150 cm | 1 J | Visibility is critical — avoid wire |
| 🦌 Deer | High-tensile 7–8 wire | 150–180 cm | 3–5 J | High-jump animals require tall fences |
| 🐷 Pigs | 2 strands low wire | 30–50 cm | 0.5 J | Pigs respond quickly — 2 strands usually sufficient |
Real-World Case Studies
Hearing how other farmers have tackled fencing challenges is one of the best ways to learn what works. Here are three real-world experiences from VetraPulse customers.
We switched from traditional woven wire to electric netting for our 200-hen flock after losing several birds to foxes. Setting up a 100m perimeter took two of us about 40 minutes. In six months, we haven't lost a single bird. The portable nature means we can move the flock to fresh pasture every two weeks — our soil health has improved noticeably as a bonus.
I manage a 300-acre rotational grazing operation for beef cattle. We run a 3-joule mains energizer on our permanent perimeter, and use solar-powered portable energizers when we subdivide paddocks for rotation. The flexibility is everything. Our grass recovery time has gone from 90 days down to 60 since we tightened up our grazing blocks.
My hobby farm has a mix of goats and ducks. I tried cheap hardware store tape once — voltage dropped to almost nothing after 50 metres. After upgrading to a properly rated 1.5-joule solar energizer and quality netting, the difference was immediate. The goats tested the fence twice in the first week and haven't touched it since.
Electric Fence Installation Tips
Even the best equipment underperforms with a poor installation. Follow these fundamentals to get full performance from day one.
Invest in Grounding
Use at least 3 ground rods, each 1.8m long, spaced 3m apart. Poor earthing accounts for 80% of fence failures.
Manage Vegetation
Grass contact drains voltage. Use a fence line herbicide strip or mow regularly beneath the fence line.
Use Quality Connections
Corroded or poor connections bleed voltage. Use proper terminal clamps and insulated connectors throughout.
Set Correct Heights
For maximum deterrence, place the lowest strand at nose height for your target animal — not at chest or knee height.
Tension Posts Correctly
Corner and end posts bear the most load. Brace them properly with deadman anchors or bracing systems to prevent lean.
Test Regularly
Use a digital fence tester monthly. A healthy fence reads 3,000V–7,000V on the line. Below 2,000V? Investigate immediately.
Maintenance, Safety & Seasonal Care
Routine Maintenance Schedule
| Task | Frequency | What to Look For |
|---|---|---|
| Voltage test along fence line | Monthly | Min. 3,000V on the line |
| Visual inspection for shorts | Weekly | Vegetation contact, broken strands |
| Check ground rods for corrosion | Quarterly | Clean connections, firm stakes |
| Battery check (battery units) | Monthly | Charge level, terminal corrosion |
| Solar panel cleaning | Monthly | Dust, bird droppings, shading |
| Energizer housing inspection | Bi-annually | Moisture ingress, rodent damage |
Safety Considerations
Electric fences are designed to be safe for both animals and humans — the pulse is extremely brief (< 0.001 seconds) and high voltage but low energy. However, always observe these precautions:
Frequently Asked Questions
The questions below cover the most common electric fence concerns we hear from farmers, homesteaders, and first-time buyers.
-
As a general guide: 0.5–1 joule for small animals (poultry, sheep, goats) in small paddocks; 1.5–3 joules for cattle and horses on medium-sized farms; 3 joules or more for large perimeters or thick-skinned animals like bison. Always choose the next size up — vegetation contact and long wire runs reduce effective voltage significantly.
-
Yes — electric netting is widely considered the gold standard for portable poultry protection. A properly energized 90–105 cm net will deter foxes, raccoons, and most dogs. Ensure your energizer maintains at least 3,000V on the fence line and that the bottom strand makes firm contact with the ground to prevent predators from burrowing underneath.
-
Stored joules is the total energy capacity of the energizer's capacitor. Output joules is what's actually delivered to the fence line after internal losses. Output joules is the number that matters for practical performance — it's usually 50–70% of the stored joule rating. Always compare energizers on output joules, not stored joules.
-
Quality solar energizers include an internal battery to bridge low-sunlight periods. Most units can operate for 2–3 weeks without direct sunlight if the battery was fully charged beforehand. For regions with extended overcast seasons, consider a larger solar panel, a supplemental battery pack, or a mains-powered unit instead.
-
Vegetation contact is the leading cause of low fence voltage. The most effective approach is a 30 cm herbicide strip directly under the fence line, applied 2–3 times per growing season. Alternatively, graze the area below the fence short before setting up. In permanent installations, a plastic weed mat under the fence line offers a long-term solution.
-
A properly installed electric fence is not dangerous to healthy adults or children — the pulse is painful but momentary (less than 1/1000th of a second). However, it is unsafe for people with heart conditions or pacemakers, who should avoid contact entirely. Always post warning signs and educate children on the fence. Never connect directly to household mains without an approved energizer in-line.
-
For electric netting, posts are integrated every 3 metres as part of the net structure. For wire or tape fencing: 5–8 metres between line posts on flat ground; 3–4 metres on hilly or uneven terrain; corner and end posts require proper bracing regardless of distance. Closer spacing on curves and corners prevents the wire from pulling out of alignment.
-
No — you should never connect two energizers to the same fence line simultaneously. Their pulses will interfere with each other and can damage both units. If you need to power a very long fence, use a single high-power energizer, or divide the fence into separate, electrically independent sections, each powered by its own energizer.
-
Training is easier than most farmers expect. Place animals in a confined paddock with the electrified fence for 2–3 days. Curious animals will investigate and receive a brief shock — after 1–3 contacts, most animals learn permanent respect. Avoid introducing hungry animals or putting fresh feed near the fence during training. For notoriously stubborn animals like goats, ensure voltage is at the high end of the recommended range.
-
Minimum effective voltage varies by animal: 2,000V for cattle; 3,000V for sheep and goats; 4,000V+ for horses and predator exclusion. As a general rule, keep your fence above 3,000V at the furthest point from the energizer. Below 2,000V, most animals will test and eventually breach the fence. Use a digital fence tester to measure — a clicker tester is not accurate enough for diagnosis.
-
Rotational grazing is one of the most powerful use cases for electric fencing. For cattle and sheep, portable poly wire or tape on step-in posts paired with a solar energizer is the fastest and most flexible system. For poultry in rotation, electric netting rolls are ideal — one person can move a full paddock in 20–30 minutes. Many farmers run a permanent perimeter of high-tensile wire and divide the interior with temporary poly tape sub-fences.
