IntelliShock 20 Energizer
For medium-length temporary and semi-permanent fences for livestock and wildlife or medium-length permanent fences for cattle and horses use this 2 joule unit.
Can be powered by either a 110v plug-in or 12v battery (replacements sold separately under accessories below).
- Peak output: 2 joule
- Pulses per minute: 38
- 110 AC draw: 3.3 watt per hour
- 12v DC draw: 32-196 mA/hr. With this energizer a 12v 100 ampere hour, deep cycle battery will last approximately 13 days* on a weedy fence or 78 days* on a clean fence. *Assumes being drawn down to 40% between recharges.
- Includes: 12v battery leads, 110v adapter and wiring harness.
- Impedance type: low
- Should power 2.5 miles of 3 strand cattle fence, 1 mile of a 6 strand sheep fence, 16 of the 164' sheep/goat nets and 6-8 of the 164' poultry nets. All distances are dependent on amount of grass/weed load on the fence.
Miscellaneous—see under Accessories Tab above
- Requires 6' of ground rod in the ground (available under accessories tab above).
- Use a 20-40 watt solar panel.
- Can be used as a solar energizer.
- Batteries are sold separately.
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 black clip to the ground terminal of the energizer. Attach black 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.
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.
- To check—first turn off the energizer.
- Then disconnect the wires going to the fence and ground rod system.
- Turn the energizer back on.
- Then measure the voltage on the energizer between the 2 terminals (fence and earth) with a digital fence voltmeter or other fence testing device. Touch one end to “–” earth terminal and the other end to “+” fence terminal.
- If the tester reads under 4000v, the energizer (or possibly the battery if it’s a battery/solar energizer) is the problem.
- If the tester reads more than 4000 volts, the energizer is working properly and the fence is the problem.
Most energizers put out between 5000v and 8000v when there is no load (i.e. no fence hooked up).
- Check that the 110v outlet is "live" by using a plug-in drill or test light.
- If the test light works and the energizer does not, call Premier.
If the energizer is faulty and you are using it as a battery unit you need to learn if the battery or the energizer is the problem…
- If it's a 12 volt energizer carry the unit to a nearby vehicle and attach the input cords carefully to the vehicle's battery.
- If the energizer now works, then your fencer's battery needs to be recharged or replaced.
- If the energizer does not work, then you should call Premier re. repairs.
If the fence is at fault, then you must find the fault(s) and fix them. Here's how to start this process: If you have a Fault Finder you can simply touch the fence with the Fault Finder at various points along the electric fence(s). The Fault Finder will tell you at each point which direction to go in to locate the problem. Move in that direction testing as you go and you will arrive at the problem.
If you lack a Fault Finder…
- Walk or drive along the fence looking for any point in which the energized wires touch the soil, a steel post or a steel wire. On HT wire fences, check the wires at braces to see if they are touching a hot wire. On netting, look for a hot wire touching the metal stake at the bottom of the plastic posts. Also look for damaged insulators.
- If the fence can be separated into several parts (by switches or by disconnecting parts of it), you can locate the problem by beginning at the far end and then progressively turn off or disconnect the sections of fence. When the voltage on the remaining fence rises sharply, you've located the section(s) that's causing the problems.
- The alternative to (2.) is to begin at the fencer and progressively turn on sections of the fence. When the voltage suddenly drops you can assume that the problem is in the section most recently connected.

This energizer is built like a TANK. The energizer has been through the elements and keeps on ticking. This unit maintains a excellent voltage over small or large areas. We use ours to keep in sheep, chickens and cows (2500 ft) and is simply an excellent unit. Be sure to have at least 3-6' of ground rod, a longer ground rod 6-8' is better but 3-6' works great too. This is the only energizer I will buy going forward.

Very pleased! Bought this charger to replace my old 42B. Mounted the new charger to the old solar base unit with a 12v battery, and it works great. It fully lights up my 7000v line test meter. I have it attached to a single line 9 gauge aluminum wire, and it is keeping my cattle where they are supposed to be.

Fencer is fairly simple to hook up and works well. Although instructions were lacking in designating how far to place 2 ground rods apart. The insulated wire included for the ground wire and fencer connection is stranded and of poor quality. It can break fairly easily when trying to strip the insulation off and manipulate it. They should have used solid wire, as I bought at my local Theisens and was much more robust to work with. Also a longer length of insulated wire should have been included in the kit, as you use most of it for placing the ground rods the minimum 33 ft away from the building and don't have much left to hook up the fencer hot wire with.

Great product. It's my second one. Nothing wrong with the first one, after 2 years of use just needed to power a separate fence and this was the best that I have tried. It's small, simple and solidly built. A competitor uses one made in Australia that feels like a very cheap toy with flimsy controls. This one works and is cheaper too. You can't go wrong with this choice

Bought this to complement the IntelliShock 10 I already own. Was a direct replacement in all regards for me, just with 2x the joule rating. No complaints, the LEDs are not nearly as bright as the prior unit which for me is a bit discouraging, but not enough to negatively impact my rating.
