Speedrite 18000i Unigizer | 18 Joule Dual Power Fence Energizer | 120 Mile
The Speedrite 18000i Unigizer is a professional-grade electric fence energizer delivering 18 joules of output energy (24J stored) with coverage of up to 120 miles (1,300 acres). It operates on three power sources — 110V mains, 12V battery, or solar — making it one of the most versatile and powerful fence energizers available for large-scale livestock and farm operations.
What is the Speedrite 18000i Unigizer?
The Speedrite 18000i is a high-output, dual-powered electric fence energizer manufactured by Speedrite. The "Unigizer" designation means it operates on mains power, battery, or solar — all in a single unit. With 18 joules of output energy and Cyclic Wave™ smart energy management technology, it is designed for serious farmers managing large properties, extensive fence lines, or remote paddocks where reliable power is critical.
Key Features
- 18J output / 24J stored energy – Powers up to 120 miles of fence with strong, consistent voltage
- 3-in-1 power (Unigizer) – Runs on 110V mains, 12V battery, or solar; battery lead and mains adapter included
- Cyclic Wave™ Technology – Smart energy management with low-energy terminal and battery saver mode
- LCD voltage display – Real-time fence voltage readout with indicator lights and earth monitoring
- Remote control compatible – Optional remote control for convenient fence management from a distance
- Adjustable output – Variable output power and pulse speed settings for different fence conditions
- Large terminals – Secure, easy connections for mains, battery, and fence leads
- Versatile mounting – Multiple mounting options for shed, post, or portable use
What is the Speedrite 18000i used for?
The 18000i is built for large-scale electric fencing applications where high output and reliable power are essential. Common uses include:
- Large cattle and livestock operations – Maintains strong voltage across extensive multi-wire fence systems
- Remote paddocks – Battery or solar mode keeps fences powered without mains access
- Rotational grazing systems – Consistent power across multiple subdivided paddocks
- Predator control – High-output voltage deters wolves, coyotes, and bears on large properties
- Horse properties – Reliable energizer for sensitive animals requiring consistent fence performance
- Ranches and acreages – Covers up to 1,300 acres on a single unit
How does Cyclic Wave™ Technology work?
Cyclic Wave™ is Speedrite's proprietary smart energy management system. It monitors fence load conditions and automatically adjusts pulse energy to optimize battery life and fence performance. In low-load conditions, the energizer reduces output to conserve power. When fence load increases — such as when vegetation contacts the wire — it increases output to maintain effective voltage. This extends battery runtime significantly compared to fixed-output energizers.
What power sources does the Speedrite 18000i support?
The 18000i Unigizer supports three power sources in a single unit: 110V AC mains power, 12V DC battery (lead-acid or lithium), and solar panel input. Both a battery lead and mains power adapter are included in the box. This makes it suitable for both grid-connected farm buildings and off-grid remote locations.
