A complete step-by-step checklist for farms, homes, and wildlife fences.
Pre-Installation Planning
- Walk the entire fence line and clear brush/obstacles
- Mark out corners, gates, and strainer points
- Measure total perimeter length
- Confirm fence purpose (security, livestock, wildlife, perimeter)
- Confirm power source (mains, battery, or solar)
- Select energizer based on fence length & type
- Ensure availability of posts, wires, insulators, and tools
Post Installation
- Install corner and strainer posts (deeply anchored)
- Install intermediate posts (spaced 8–12 metres)
- Use tarimbo to ensure straight, uniform holes
- Concrete corner posts where necessary
- Ensure post height matches fence plan
Insulators
- Install UV-treated insulators
- Use heavy-duty corner insulators
- Replace damaged or cracked insulators
Wire & Conductor Setup
- Run wires in correct order (bottom up)
- Maintain consistent spacing
- Use tensioners/ratchets to tighten wires
- Use underground cable where wires cross roads/gates
Earthing System
- Install minimum 3 earth rods (3m apart)
- Drive rods deep using tarimbo
- Use proper earth cable
- Test earth voltage (<300V on earth stake)
Energizer Setup
- Mount energizer indoors or in a weatherproof housing
- Connect to battery/mains/solar controller
- Add surge protection
- Label the energizer area
Final Testing
- Test fence voltage (6,000–12,000V ideal)
- Check every wire section for drops
- Test alarm and siren (for security fences)
- Inspect grounding effectiveness
2. ENERGIZER SELECTION CHART (KENYA)
Choose the right energizer based on fence length, purpose, and animal type.
By Fence Length
| Fence Length | Recommended Energizer | Brands in Kenya |
|---|---|---|
| 0–2 km | 1–3 Joules | Nemtek, JVA, Gallagher |
| 2–5 km | 3–6 Joules | Nemtek Merlin, Stafix M3/M6 |
| 5–15 km | 6–12 Joules | Stafix M12, Thunderbolt |
| 15–40 km | 12–25 Joules | Stafix 46000W, Gallagher M1800 |
| 40+ km | 30–50 Joules | Wildlife-grade units |
By Application
| Application | Recommended Joules |
|---|---|
| Home/Urban Security | 3–6 Joules |
| Livestock Fencing | 3–8 Joules |
| Game & Wildlife | 12–50 Joules |
| Industrial Security | 6–12 Joules |
By Animal Type
| Animal | Joule Rating |
|---|---|
| Cattle | 3–6 Joules |
| Goats/Sheep | 3–4 Joules |
| Hyaena/Leopard | 8–12 Joules |
| Elephants | 20–50 Joules |
3. SOLAR SIZING CALCULATOR (FOR ELECTRIC FENCES IN KENYA)
Use this to size solar systems for electric fence energizers.
Step 1: Identify Energizer Power Consumption
Typical energizer usage:
- Small energizer: 5–10W
- Medium energizer: 12–18W
- Large energizer: 20–40W
Step 2: Select Battery Size
Recommended Battery Capacity:
- Small fence: 100Ah (12V)
- Medium fence: 150Ah (12V)
- Large fence or wildlife fence: 200Ah (12V)
Battery type:
- GEL battery (best for deep-cycle)
- Lithium (high efficiency, long life)
Step 3: Solar Panel Size
Use this formula:
Solar Panel Size (Watts) = (Energizer Wattage × 5 Hours) × 2
Recommended sizes:
- Small system: 150–200W panel
- Medium system: 250W panel
- Large system: 300W–400W panel
Standard Kit for Kenya:
250W Panel + 100Ah/200Ah Battery + 30A Controller
Step 4: Charge Controller
Minimum:
- 30A PWM or MPPT
MPPT recommended for cloudy/forest regions (e.g., Kericho).
Step 5: Backup Runtime
Battery runtime (days) = Battery Ah ÷ (Load in Amps × 24)
Example:
200Ah battery with a 15W energizer → 7–10 days backup.
4. ELECTRIC FENCE MAINTENANCE LOG (MONTHLY/QUARTERLY)
