Thunderbird S35B Lithium Solar Fence Energiser

The Thunderbird S35B is a compact, self-contained solar electric fence energiser designed for portable livestock control and smaller permanent fencing systems. With 0.30 joules of stored energy, it can power up to 3.5km of clean fencing under ideal conditions.

An internal 3.2V lithium battery stores energy collected by the integrated solar panel. The S35B also includes automatic battery preservation, which reduces the pulse rate when the battery charge becomes low to help extend operating time.

Internal Lithium Battery

The S35B uses an internal 3.2V 6Ah lithium battery to store energy collected by its solar panel. Lithium battery technology provides a compact and lightweight power source suitable for portable electric fencing.

When the battery charge becomes low, the energiser automatically reduces its pulse rate to conserve remaining energy and help keep the fence operating for longer.

Full and Reduced Power Settings

The selectable power levels allow the energiser’s operation to be adjusted for different fence conditions. Full power can be used when stronger performance is required, while the reduced setting can help conserve battery energy on shorter, cleaner fences.

Fence voltage should be checked with a suitable electric fence tester after installation and whenever the power setting is changed.

Quick Portable Installation

The moulded enclosure is designed to slide directly over a standard steel star post. This allows the energiser to be installed quickly without constructing a separate mounting frame.

Its compact self-contained design makes the S35B suitable for strip grazing, temporary paddock divisions, small livestock areas and remote fence locations.

Positioning the Solar Panel

Install the energiser where the solar panel will receive direct sunlight throughout the day. In Australia, the panel should generally face north and remain free from shade caused by trees, buildings, fences or equipment.

Clean dust, dirt and bird droppings from the panel when required. Reduced sunlight or a dirty panel can limit battery charging and shorten operating time.

Understanding the Fence Distance Rating

The advertised 3.5km distance represents a clean fence operating under ideal conditions. Vegetation touching the live wires, poor connections, damaged insulators and inadequate earthing can substantially reduce its effective working distance.

Choose a larger solar energiser for long multiwire fences, electric netting, substantial vegetation or systems that may be expanded later.

Is the Thunderbird S35B Right for Your Fence?

The S35B is a practical choice for short, clean fences where mains electricity is unavailable. It is well suited to strip grazing, temporary paddock divisions and small permanent livestock fences requiring a portable self-contained solar unit.

For fences exposed to heavy vegetation, multiple live wires or future expansion, select a larger solar energiser with additional stored energy and battery capacity.

Correct earthing is essential. Contact Horsley Wholesale if you need help choosing a solar energiser, portable earth stake or temporary fencing equipment.
