IntelliShock 20 Energizer

★ ★ ★ ★ ★ (13) Read reviews »

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.

Plug unit into a 110V wall outlet, or connect to an external 12V battery. (Connectors included for both. See Specifications below.)

Instructions/Diagrams:

Common Uses
A 110V AC or 12V DC electric fence energizer used mostly to keep out deer, raccoons and rabbits from garden/orchard areas. It is also used to keep in poultry, cattle, sheep, goats, horses, and guard dogs. Effective at protecting against coyotes, stray dogs, bear and fox.

*Kits include all the parts and pieces that folks new to electric fence normally need to make the fence operational.

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
  • Up to 8 of the 164' poultry nets
**All distances are dependent on amount of grass/weed load on the fence. Low-impedance circuitry produces a short, very strong electrical pulse designed to cope with moderate weed load.

Miscellaneous

  • Requires a grounding system. Inadequate grounding is the most common failure in an electric fence system. We recommend 6 ft. of grounding for this energizer.
  • 12V battery draw is 32-196 milliampere (mA) per hour. With this energizer a 12V, 100 ampere hour deep-cycle battery will last approximately 13 (on a weedy fence) and 78 (on a clean fence) days. (Assumes 40% drawn down between charges.)
  • To operate as a solar energizer, run the unit as a battery unit (DC) and attach a solar panel to charge the battery. (10-40 watt panel recommended.)

Energizer Specifications

  • 2.00 released joules
    • 2.00 joules in moist soils
    • 0.45 joules in dry soils
  • Pulses per minute: 38
  • 12V DC draw: 32-196 mA/hr
  • 110V draw is 3.3 watt per hour
  • Impedance type: low – pulse type
  • Load sensing/variable draw: yes
  • Input: AC/DC
  • A wiring harness is included to connect energizer to fence and energizer to ground rod.

Benefits
Versatile. Can be used as a plug-in energizer or as a battery energizer. Adapts from one style to the other in a few seconds. Can be moved around easily. Low cost.

Installation

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.
  1. 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.
  2. 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.
  3. Secure to ground rod(s) with a clamp.
  4. 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:

  1. Attach wiring harness to energizer.
  2. 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.
  3. 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).
  4. Connect the energizer to the battery.
  5. Insert battery adapter into the energizer. Attach red alligator clip from the adapter to the red “+” terminal of the battery.
  6. 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.

Precautions
Make sure the power is turned off before working on the fence or the energizer.

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.

Troubleshooting
You’ll need an electric fence tester (included with kit) to measure voltage.

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.

  1. Turn off the energizer.
  2. Disconnect the wires going to the fence and ground stake/rod.
  3. Turn the energizer back on.
  4. 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.
  5. 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.
Determine if the battery or the energizer is the problem.
  • Test the battery with a low-voltage tester; recharge if lower than 12.2 volts
  • Check the grounding system
LEARN MORE
Re-attach the fence and ground wires to the energizer and turn it on. Then, walk or drive along the fence looking for situations that are reducing the voltage:
  • Conductors touching another wire, steel post or the soil
  • Broken or damaged insulators

Warranty
3-year warranty for energizers and solar panels cover lightning damage and defective parts or workmanship. Should an energizer fail, we will replace the unit, bill you for the cost to do so, then reimburse you for warranted expenses after we have examined the failed unit. Misuse and flood damage are not covered.

IntelliShock 20 Energizer
★ ★ ★ ★ ★

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.
