The Power Behind Your Fence
Electric fencing is only as effective as the energizer powering it. Whether you’re protecting a small garden or a full game reserve, electric fencing energizers are the heartbeat of any secure system.
Choosing the wrong energizer can lead to system failures, poor containment, or unnecessary energy costs. At Advanced Electric, we supply a wide range of energizers—from compact units for backyard setups to heavy-duty models suitable for long-range fencing. While we don’t install systems, our goal is to equip you with the right tools for your needs.
This guide will help you understand the most important factors in selecting electric fencing energizers and highlight our most popular models, so you can shop smart and secure.
I. What Is an electric fencing energizers ?
An electric fencing energizers (also called a fence charger) converts power—either from mains electricity, battery, or solar—into high-voltage pulses that travel through the fence wire.
The energizer’s job is to:
- Deliver short, sharp electric pulses
- Maintain a consistent charge across the entire fence
- Deter animals or intruders without causing harm
There are two main types:
- Mains-powered energizers
- Battery or solar-powered energizers (ideal for remote areas)
II. Key Factors to Consider When Choosing an electric fencing energizers
1. Fence Length & Wire Configuration
- Total wire length = number of strands × total fence perimeter
- Larger fences require energizers with greater joule ratings
2. Animal Type
| Animal | Recommended Output |
|---|---|
| Chickens | Low power (0.5–1 J) |
| Goats & Sheep | Medium power (2–5 J) |
| Cattle & Horses | Medium to high power (4–8 J) |
| Game (e.g. buffalo, kudu) | High power (8–15 J) |
3. Vegetation Load
- Heavy vegetation along the fence line drains voltage
- Choose a more powerful energizer to compensate
4. Power Source Availability
- Is there reliable mains access?
- If not, opt for battery or solar-compatible energizers
5. Security Goals
- For intruder deterrence, higher-voltage energizers are better
- Monitorable energizers with alarm integration offer added protection

IV. Common Energizer Misconceptions
Myth: A stronger energizer will shock more effectively, no matter the setup.
Fact: Joules must match the fence’s needs—too much power can cause shorts or safety risks.
Myth: Any energizer works for all animals.
Fact: Energizer power must align with animal type, temperament, and behavior.
Myth: Solar energizers are weaker.
Fact: Modern solar energizers can match or exceed battery-powered models—if sized correctly.
V. Installation & Maintenance Tips (For DIYers and Contractors)
Advanced Electric does not install fencing systems, but we support your project with the best components.
Setup Reminders:
- Grounding is crucial—use at least 3 galvanized earth rods, spaced 1.5–2 m apart.
- Place energizer in a dry, protected location.
- Use insulated cable for connections between energizer, fence, and ground rods.
Ongoing Maintenance:
- Test voltage weekly using a fence tester.
- Keep vegetation trimmed to prevent grounding shorts.
- Replace batteries (if used) every 1–2 years.
VI. How to Calculate the Right Energizer Size
- Measure your total fence length.
- Multiply by the number of wire strands.
- Account for vegetation load (low, medium, or heavy).
- Choose an energizer with:
- Stored energy (joules) that matches or exceeds your load
- Enough voltage (ideally 7,000–10,000 volts at output)
Example:
- Property: 500m perimeter × 5 wires = 2,500m of fencing
- Medium vegetation load
- Ideal Energizer: 4–8 joules output (e.g., Rhino Energizer)
