Introducing Thunderbird’s new range of solar energisers for electric fences, the S30B is an easy-to-install and use product for every farmer. It has a case that quickly slides over the topmost portion of the star post. Mounting can be completed in just a few steps.

Additionally, the product already comes with earth leads and fence. It also comes with handy pulse/operation lights, along with low battery warning. You can use these signals to know the status of the system.

Thunderbird designed the S30B to be fully portable and has its own rechargeable battery. It also has a carry handle for easy use and moving from one site to another when required. The solar electric fence energiser has a mains AC charger as well, which allows it to function even when exposed to poor weather conditions for an extended period.

S30B offers a choice between low and high power levels. When using low power, it helps conserve the system’s battery.

This electric fence energiser uses solar energy to power the whole system. It has encapsulated electronics to ensure the interiors are well-protected from moisture and damage caused by insects. The product is covered by a two-year warranty.

Taking convenience to a whole new level with the S-30B from Thunderbird.
