Safety Features in Solar Fencing Jhatka Machine
Solar fencing systems, commonly called solar jhatka machines or simply jhatka machines, are widely used by farmers in India to protect crops from wild animals and unauthorized intrusion.
But modern fencing energizers do more than just deliver electric pulses-they now include advanced safety features to safeguard farmers, livestock, and equipment.
Below is a detailed guide to the most important safety features to check before buying a solar fencing machine.
🔐 Why Safety Features Are Important in Solar Fencing Machines
Though solar electric fencing is designed to be non-lethal and low-current, the right safety mechanisms ensure:
- Protection of energizers and batteries during storms or short circuits
- Reduced battery drain for longer performance
- Instant alerts if fence lines are tampered or broken
- Higher system reliability and farm security
🛎️ Siren & Fence Fault Alarm
Advanced solar jhatka machines now include in-built sirens or alarms to alert users when:
- The fence wire is cut or tampered
- Fence voltage drops below safe limits
- Animal intrusion is detected
Examples: Crown Solar SF-series and Fieldmaster ISI-marked energizers include built-in fence alarms.
🔋 Low-Battery Cut-Off & Power Modes
To extend battery life and ensure reliable performance, modern controllers offer:
- LED or digital low-battery indicators
- Automatic cut-off or low-power mode when charge drops
- High/low power adjustment for wet vs dry soil conditions
Crown Solar and Galaxy energizers come with automatic low-battery cut-off and dual power modes.
⚡ Lightning Diverter & Over-Voltage Protection
One of the biggest threats to solar fencing is lightning. Quality systems are designed with:
- Built-in lightning diverters
- Surge protection compliant with IEC safety standards
Brands like Fieldmaster and Crown Solar list lightning protection in their technical specs.
🔄 Reverse Polarity Protection
Improper battery wiring is a common mistake during installation. Reverse polarity protection prevents damage by:
- Automatically cutting off if battery terminals are reversed
- Blocking reverse current flow
Standard in models from Galaxy, Keviya Solar, and Fieldmaster.
💡 LED Indicators & Real-Time Monitoring
Smart jhatka machines use LED panels or digital displays for:
- Fence voltage levels (multi-stage indicators)
- Battery charging & discharge status
- Fault alerts and auto-cut warnings
Crown Solar SF-series offers a 10-stage LED voltage display, while Fieldmaster energizers show battery, fence, and heat alerts.
🧱 ISI/BIS & IEC Safety Compliance
Before purchasing, always check for certified safety compliance:
- BIS 302-2-76 (ISI mark) for Indian standards
- IEC-60335-2-76 for international fencing safety
Crown Solar and Fieldmaster energizers carry ISI/BIS certifications.
🧰 Installation Safety Best Practices
To maximize safety and efficiency, follow these guidelines:
- Install controllers in shaded, elevated areas
- Disconnect fence lines during thunderstorms
- Use at least three grounding rods, kept separate from mains earth
- Regularly clear vegetation around fence wires

📍 Why These Features Are Crucial for Indian Farmers
India’s rural farming conditions demand durable and safe fencing systems. These features provide:
- Lightning protection for monsoon storms
- Battery safety to increase system lifespan
- Immediate local alerts with sirens
- Protection from wiring mistakes
📌 FAQs on Solar Fencing Safety Features
Do all solar jhatka machines come with alarms?
No, basic models may not. For built-in alarms, choose brands like Fieldmaster, Galaxy, Keviya, or Crown.
Should the fence be disconnected during lightning storms?
Yes. Even with lightning diverters, it is safer to isolate the fence during severe thunderstorms.
What if battery polarity is reversed during setup?
Without reverse polarity protection, the controller can be damaged. Always check wiring or buy models with built-in safeguards.
Is low-battery cut-off really necessary?
Yes. It prevents deep discharge, extends battery life, and ensures the energizer keeps working efficiently.
Which certification should farmers look for?
Always check for ISI/BIS certification and IEC-60335-2-76 compliance before buying.
