Gallagher S120Li Lithium Solar Electric Fence Energiser

The Gallagher S120Li is a compact, solar-powered electric fence energiser featuring a built-in lithium battery. It weighs less and is more compact than comparable models, yet remains capable of delivering up to 10 kV and 1.2 joules of output for multi-wire fences up to 12 km. Designed for reliability year-round, it uses a 12 W solar panel and intelligent energy management to charge quickly in daylight and sustain operation through periods of low light. The device includes a game mode for deterring wildlife and a rugged, maintenance-free build with a sealed housing, double-glazed solar panel, and built-in lightning protection. It is part of a lithium-based range and is backed by a seven-year warranty (including three years on the battery). The energiser is designed for easy transport, installation on posts or ground rods, and simple monitoring of fence voltage, with useful indicators to show voltage levels. This model aims to balance portability with performance across various livestock and wildlife management scenarios.

Usage

Mount the energiser using the included bracket on a post or earth stake, or use the stand that can be driven into the ground. Place the solar panel facing south-west and keep vegetation clear. Earth the unit with two 1-metre earth stakes. Use the red and green cables with crocodile clips to connect to the fence and earth stake. After purchase or storage, allow daylight charging for three days with the unit in the off position facing south. In long-term storage, keep the device in a dark, dry and ventilated place.

Follow installation guidelines: mount on a post or stand, place solar panel facing south-west, keep vegetation clear, and earth with two 1-metre stakes. Do not place the device on the ground and use the provided bracket or stand for mounting. Ensure daylight charging by exposing the unit to light during storage and after periods of low battery.
