Thunderbird B120 Solar Energiser Kit

The B120 solar energiser kit gives farmers a practical way to power livestock fencing where mains electricity is unavailable. Combining the Australian-made Thunderbird B120 energiser with a 10W solar panel, it helps you maintain dependable animal control in remote paddocks and small permanent fencing systems.

The B120 delivers 1.5 joules of stored energy and is promoted for fence systems up to 12km under suitable conditions. A correctly designed fence, effective earthing and regular vegetation control are essential for reliable performance.

Why Choose the B120 Solar Energiser Kit?

• Practical off-grid power for remote paddocks
• Australian-made Thunderbird energiser
• 1.5 joules of stored energy
• Supplied with a 10W solar panel
• Designed for small permanent electric-fence systems
• Suitable for livestock and general farm fencing

A Reliable Solution for Remote Paddocks

Running mains power to an isolated fence can be expensive or impractical. This kit allows the B120 to operate from an external 12V battery while the solar panel helps maintain the battery’s charge during normal operation.

The compact energiser can hang from a live fence wire or tape, or it can be secured to a suitable post. This makes installation straightforward while allowing the unit to be positioned close to the fence and earth system.

What Is Included?

• Thunderbird B120 electric fence energiser
• 10W solar panel
• 12V DC battery lead

Please note: A suitable external 12V battery is required and is not included.

Understanding the 12km Rating

The stated 12km distance is an ideal-condition rating rather than a guarantee that the energiser will effectively power every 12km fence. Actual performance depends on how much electrical load is placed on the system.

Vegetation touching the live wires, poor joins, damaged insulators, inadequate earthing, unsuitable conductors and multiple live wires can significantly reduce effective fence distance. A shorter, heavily loaded fence may require more power than a longer, clean single-wire fence.

Battery and Solar Performance

The B120 draws approximately 105mA during operation. Battery capacity, panel position, seasonal sunlight, vegetation load and fence condition will all affect how long the system can operate without additional charging.

Install the solar panel in a position that receives strong, uninterrupted sunlight throughout the day. Avoid shade from trees, buildings and machinery, particularly during winter.

Correct Earthing Is Essential

A reliable earth system allows the electrical pulse to travel through the animal and return to the energiser. Without effective earthing, even a correctly operating energiser may produce a weak shock at the fence.

Install suitable galvanised earth stakes in permanently moist ground and keep the earth system clear of building earths, underground services and other electrical systems. Dry, sandy or rocky soil may require additional earth stakes or an earth-return fence design.
