The Solar Powered 8km Electric Fence Energiser is designed to electrically charge your fence with a 7.5V DC charge producing a high voltage 8.0kV pulse that reduces to 1.2kV upon contact. This output is harmless to animals but an extremely effective deterrent. It's energy efficient as it uses solar power, thus driving down your farm's operational expenses. The energiser will work up to 3 days straight through consistent cloudy and rainy weather. A back-up charger can also be used to charge the unit for continuous operation. Moreover, the unit features an automatic shut-off and activation function to maximise battery life, whereby temporary deactivation of the battery occurs if its capacity falls below 20%, and automatically reactivates once capacity reaches 50%. This innovative feature allows for more efficient battery re-charging.
