Premier 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.
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.
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.)
Installation
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.
Battery unit:
- Attach wiring harness.
- Attach the bare wire with the red clip to the fence terminal. Attach the red clip to the fence.
- Attach the bare wire with the black clip to the ground terminal. Attach black clip to the ground rod(s).
- Connect energizer to the battery.
- Insert battery adapter. Attach red clip from the adapter to the red “+” terminal.
- Attach black clip from the adapter to the black “–” terminal.
Precautions
- Make sure the power is turned off before working on the fence or the energizer.
- 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.

this is a very powerful energizer, i do recommend getting a lot more than you think you need because this is one item that you can future proof. it is also a very compact size which worked for me as i made a custom portable charge box.

I’m using this with my poultry and goat net fence from Premier. It works great.

This charger was purchased to replace a 60+ year-old "Shock-Stock" fence controller. I've been using it for almost a month on 3/4 of a mile of single-strand fence holding four 500 lb. calves. So far, so good... It appears to really pack a punch and seems to works fine in rainy weather (even with a few weeds on it, here and there). I chose this model for the possibility of using a 12 volt deep-cycle battery with it when the power goes out, but I have not yet tested this functionality.

Product had defective power supply that was replaced by supplier but it took a while to get the replacement.

Great fencer. I used it in the garden for racoons and it did the job.
