The S120 is the top model in Gallagher's S-series lithium solar energizer range. It uses adaptive energy control technology to automatically adjust output based on available sunlight and battery charge level, maximizing fence performance at all times without manual adjustment. The integrated lithium battery provides significantly better cold-weather performance and longer cycle life than lead-acid alternatives.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e1.2 joule adaptive stored energy\u003c\/strong\u003e – Industry-leading output for a solar energizer; powers long fence runs and handles heavy vegetation contact\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e35-mile (56 km) coverage\u003c\/strong\u003e – Suitable for large paddocks, remote boundaries, and multi-strand livestock fence systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdaptive energy control\u003c\/strong\u003e – Automatically adjusts output based on solar input and battery charge for optimized efficiency\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLithium battery technology\u003c\/strong\u003e – Superior cold-weather performance, longer cycle life, and lighter weight vs lead-acid solar energizers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in high-efficiency solar panel\u003c\/strong\u003e – Integrated panel continuously charges the lithium battery during daylight hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLightweight and portable\u003c\/strong\u003e – Designed for rotational grazing; easy to move between paddocks without tools\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUV-stabilized housing\u003c\/strong\u003e – Weather-resistant construction for year-round outdoor use in all climates\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat is the Gallagher S120 used for?\u003c\/h2\u003e\n\u003cp\u003eThe S120 is designed for off-grid electric fencing applications where mains power is unavailable or impractical.

It continuously monitors available solar input and battery charge level, then automatically adjusts the energizer's output pulse to match available power. In full sun with a charged battery, it delivers maximum output. During extended cloudy periods or low battery conditions, it reduces output to extend battery life and keep the fence operational rather than shutting down entirely. This eliminates the need for manual output adjustment and ensures the fence stays powered through variable weather conditions.\u003c\/p\u003e\n\n\u003ch2\u003eHow does the Gallagher S120 compare to other S-series models?\u003c\/h2\u003e\n\u003cp\u003eThe S120 is the highest-output model in Gallagher's lithium solar S-series range. Lower-output models such as the S10, S20, S40, and S100 cover shorter fence runs and suit smaller properties or fewer livestock. The S120's 1.2-joule output and 35-mile coverage make it the right choice for large farms, extensive boundary fencing, or operations with heavy vegetation on the fence line that requires higher voltage to maintain effective containment.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Gallagher S120 Lithium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e G352404\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStored energy:\u003c\/strong\u003e 1.2 joules (adaptive)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoverage:\u003c\/strong\u003e Up to 35 miles \/ 56 km\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower source:\u003c\/strong\u003e Built-in solar panel + lithium battery\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnergy management:\u003c\/strong\u003e Adaptive Energy Control (automatic)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery type:\u003c\/strong\u003e Lithium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCold-weather rated:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing:\u003c\/strong\u003e UV-stabilized, weather-resistant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Portable; post or fence-mountable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of origin:\u003c\/strong\u003e New Zealand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Gallagher\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e FENELEG352404\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat's Included\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGallagher S120 Lithium Solar Energizer unit with integrated solar panel\u003c\/li\u003e\n\u003cli\u003eLithium battery (built-in)\u003c\/li\u003e\n\u003cli\u003eFence and ground lead cables\u003c\/li\u003e\n\u003cli\u003eMounting hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e No mains power connection required.
