Technical working mechanism and solar components
- Solar energizer unit: Converts 12V DC battery power into brief high-voltage pulses (typically 6,000 to 10,000 volts) lasting less than 1 millisecond.
- Pulse frequency: Emits one brief pulse every 1 to 1.2 seconds; animals feel a sharp shock and retreat immediately, associating the boundary with danger.
- Solar panel and battery: 20W to 40W solar panel paired with a 12V 14Ah to 28Ah deep-cycle battery ensuring uninterrupted nocturnal operation.
- Earthing system: Minimum 2 to 3 galvanized earth rods driven deeply into moist ground to complete the electrical circuit when an animal touches the wire.
Statutory legal compliance and non-lethal safety
Under Indian law and Bureau of Indian Standards (BIS / IEC 60335-2-76) guidelines, agricultural electric fences must strictly deliver pulsed, non-lethal shocks. Directly connecting boundary wires to domestic 230V AC mains or continuous lethal currents is a severe criminal offense punishable under the Indian Penal Code and Wildlife Protection Act.
Installation best practices and subsidies
Use high-tensile galvanized GI wire supported on insulated posts (corner porcelain insulators and plastic line insulators) to prevent grounding through vegetation. Clear weeds along the fence line regularly. Capital subsidies for solar fencing are provided under state wildlife crop protection and agriculture schemes.

Common questions
How does a solar zatka machine protect crops without harming animals?
It emits extremely short (microsecond) high-voltage, low-amperage pulses that deter animals through psychological shock without causing physical injury.
Is it legal to connect farm fences directly to 230V domestic electric lines?
No, connecting continuous 230V mains power to farm fences is strictly illegal and punishable as a criminal offense.
Why is proper earthing critical for an electric fence?
The electrical shock only completes its circuit when the animal touches the wire and the charge flows back through moist earth to the energizer's earthing rod.
