Enjoy convenient and reliable livestock control with the Thunderbird S-50B 5km Solar Electric Fence Energiser, a feature-packed unit available at The Grit. This model is designed for ultimate portability and ease of use, featuring a sturdy carry handle and the ability to slide directly onto a standard steel star post for instant mounting. It effectively harnesses solar energy to power up to five kilometres of fence line, with a built-in rechargeable battery ensuring consistent operation after dark or during cloudy weather. A new digital display provides clear, at-a-glance information, while a clever magnetic switch eliminates holes in the casing for superior weather protection. The tough, O-ring sealed enclosure and non-corrosive solar panel mounting ensure durability in harsh Australian conditions. For added versatility, it includes a mains AC charger with a weatherproof port cover and offers both high and low power settings to help conserve battery life when needed. This energiser is the perfect set-and-forget solution for modern, flexible farm management.
