12 Joules of High-Performance Fence Power — Remote-Ready, Solar-Compatible, Built for Large Operations
When you're running serious acreage, you need an energizer that can handle the load — vegetation contact, long runs, multiple strands — without dropping voltage or requiring constant attention. The Speedrite 12000i delivers 12 joules of output energy using Cyclic Wave™ technology for a cleaner, more powerful pulse that maximizes energy delivery down the fence line. It runs on mains, 12V battery, or solar, and it's remote-ready so you can switch it on or off from anywhere along the fence without walking back to the energizer.
The backlit LCD display shows output voltage, battery voltage, and earth voltage at a glance. Earth monitoring alerts you to grounding problems before they become fence failures. Battery saver technology automatically adjusts output based on battery condition — extending runtime in solar and battery installations. Add the remote (sold separately, ST102) to take full control of your fence from the field.
Features
12 Joule Output with Cyclic Wave™ Technology
Cleaner, more powerful pulses maximize energy delivery down the fence — better livestock control even on loaded fence lines.
Remote Ready
Switch the energizer on or off from anywhere along the fence line using a Speedrite remote (ST102, sold separately). Manage repairs and maintenance without walking back to the unit.
Backlit LCD Display
Shows output voltage, battery voltage, and earth voltage — readable in low light conditions for early morning and evening checks.
Earth Monitoring
Monitors grounding system voltage and alerts you to earth problems before they compromise fence performance.
Battery Saver Technology
Microprocessor automatically adjusts output based on battery condition — extends runtime in solar and battery installations.
Day/Night Sensor
Automatically adjusts pulse speed based on time of day for smarter livestock control.
Mains, Battery & Solar Compatible
Run on 12V battery, 100–240V mains, or solar — place it where your fence needs it.
Low Interference
Cyclic Wave™ technology minimizes electromagnetic interference in line with international EMC standards.
Half Voltage Terminal
Limit energy output for use around buildings and sensitive areas.
