Speedrite 18000i Energizer
Large (18 joule) low-impedance unit for extra long fences with heavy grass contact. Includes earth monitoring system to measure ground system voltage.
Plug unit into a 110V wall outlet, or connect to an external 12V battery. (Connectors included for both. See Specifications below.)
- Peak output: 18.00 joules
- Pulses per minute: 25/40
- 12V DC draw: 1400 mA
- 110V draw is 19 watts per hour
- Impedance type: Low
- Input: AC/DC
- Low Energy Terminal. Limits energy to below 1.5 J for use around buildings and houses.
- Remote capable (remote sold separately #133510). Using a Speedrite fence remote (with remote capable Speedrite energizers enables you to switch the energizer on or off from anywhere along the fence line. This makes it easy to manage repairs and maintenance.
- LCD voltage display. Displays output voltage, battery voltage and earth voltage. LCD is backlit for viewing in poor light conditions.
- Indicator lights (voltage and battery). Easy to read light bar display provides an instant measure of the Unigizer output voltage and battery condition for quick fence diagnostics. The LED display shows red when heavily loaded.
- Battery saver. Microprocessor technology automatically adjusts the output energy depending on the battery condition. This feature extends battery life and is particularly efficient when used in solar installations.
- Day/Night sensor. Automatically adjusts pulse speed to contain or exclude animals based on day or night conditions.
- Large terminals. Mounted on the front of the energizer casing for convenience, these large terminals are easily adjusted and accept up to two fence wires. The slotted terminals make inserting wires and getting a good connection easy.
- Earth monitoring. Indicates earth system problems by monitoring the level of voltage around the earth system.
- Versatile mounting options. Can be mounted on a wall, post or fence wire. Choose indoor or outdoor installation, depending on your fence location and power supply.
- Versatile power options. Can be used in mains, battery or solar power applications, providing convenient, versatile livestock control.
- Adjustable output power and pulse speeds.
To use the energizer as a plug-in unit:The energizer can be mounted either inside or outside of a building, but not where there is risk of fire. The energizer must be mounted vertically. Protect the energizer from direct rainfall.
- Connect an insulated cable (stripped back 1 - 2" on ends) to the fence terminal on energizer, run the cable to the fence line and connect, or use the positive part of the wiring harness.
- Then run a second length of cable from the ground terminal (with ends stripped again) on the energizer to the ground rod(s), or use the negative part of the wiring harness.
- Secure to ground rod(s) with a clamp.
- Plug the energizer directly into an outlet and test fence. Do not use an extension cord as it may cause a decrease in voltage and expose the unit to the elements.
To use the energizer as a battery unit:
- Attach wiring harness to energizer.
- Attach the bare end of the wire with the red clip to the fence terminal of the energizer. Attach the red alligator clip to the fence.
- Attach the bare end of the wire with the green clip to the ground terminal of the energizer. Attach green alligator clip to the ground rod(s).
- Connect the energizer to the battery.
- Insert battery adapter into the energizer. Attach red alligator clip from the adapter to the red “+” terminal of the battery.
- Attach black alligator clip from the adapter to the black “–” terminal of the battery.
Unit indicator light should flash and a tic-tac sound will be heard. If the indicator light doesn't flash, then the unit/battery should be checked.
Start by measuring the voltage at the end of the fence line. If the voltage is below 3000V, follow these steps to determine if the problem is with the fence, or the energizer.
Test the energizer first!
- Turn off the energizer.
- Disconnect the wires going to the fence and ground stake/rod.
- Turn the energizer back on.
- Measure the voltage on the energizer between the two terminals (positive and negative) with a digital voltmeter or other high-voltage tester. Touch one end to “-“ (earth terminal) and the other end to “+” (fence terminal). The reading tells you how well the energizer is working without any other variables.
- If the tester reads below 5000V, then the energizer (or possibly the battery) is the problem. If the voltage is above 5000V, then the trouble lies with your fence.
If the fence is at fault:
- Conductors touching another wire, steel post or the soil
- Broken or damaged insulators
To Reduce Risk & Liability
- Never place your head or upper spine near an electrified wire. Accidental head or neck contact can occur when pushing a voltage probe into the soil. Be careful when doing so to avoid head-to-wire contact!
- Never attempt to step over or climb through an energized fence of any kind.
- Never encourage anyone to touch an electric fence.

We have the Stafix version (X18i). Same unit I'm pretty sure. Good and powerful. It will burn through nets that are grounding out; the wire and plastic both melt. Look for sparks at night and rectify before it's too late. You can turn the power down if you don't need 9000 volts. The remote is very handy and works well. We like that the unit is 12v natively, you can run it off a deep cycle battery and trickle charge with solar to be offgrid. (also plugs in to 120v ac with a wall wart).
