The Stafix X18i Unigizer is a top‑tier electric fence energizer built for very large perimeters, suitable for expansive farms, game reserves, or high‑security fencing. It delivers about 18 joules of maximum output energy (24 J stored), enabling it to power up to ~180 km of multi‑wire fencing (≈ 270 acres / 110 hectares). It supports versatile power options — mains, battery, or solar — and includes smart features such as a backlit LCD display showing output voltage, earth condition, and battery status, LED indicators for voltage & battery load, a day/night sensor, remote control capability, large wire terminals, earth monitoring, and a low‑energy terminal for safer zones near buildings. It’s made for durability, strong pulses even under heavy load or challenging soil conditions, and for ease of maintenance over long fence lines.
