The Thunderbird S50B Solar Fence Energiser is a portable, high-performance unit capable of powering fences up to 5km, making it perfect for small to medium-sized farms, cell grazing, or remote fencing setups.
Designed for convenience and durability, it features a large, easy-to-read LCD display and a fully weatherproof O-ring sealed case, with resin-sealed, coated electronics for long-lasting protection. The internal rechargeable battery ensures reliable operation even in low-sun conditions, while a magnetic switch eliminates holes in the case, improving waterproofing.
Installation is quick and simple: the unit slides directly over a steel star post, includes fence and earth leads with insulated grips, and comes with a strong moulded carry handle for easy portability. The S50B also provides low and high power settings to conserve battery life, and a low battery warning alerts you when it’s time to recharge. A mains battery charger is included for overnight charging during poor weather.
