Thunderbird 3.5km Solar Energiser with Lithium Battery | S-35B

Setting up a reliable electric fence doesn't have to be complicated, and with the Thunderbird S-35B Solar Energiser from The Grit, you can get power exactly where you need it. This compact unit is designed for portability and ease of use, making it perfect for strip grazing or smaller permanent setups. It packs enough punch to power up to 3.5km of fence wire, delivering a solid 9,100 volts with 0.30 Joules of stored energy. What makes this model stand out is the internal 3.2v lithium battery, which charges off the sun and features an automatic preservation mode that drops the pulse rate to keep running longer when the charge gets low. It is built tough for Australian conditions, featuring a fully O-ring sealed case to keep the weather out. They have even used magnetic switches to avoid drilling holes in the casing, ensuring moisture cannot get in to damage the electronics. With options for full or reduced power settings, it is a versatile, set-and-forget solution for keeping your livestock secure.
