Patriot P30 Energizer
Use this 3 joule energizer for long temporary and semi-permanent sheep, goat, poultry and wildlife-deterrent fences, long permanent cattle fences and medium-length permanent sheep and goat fences.
Plug unit into a 110V wall outlet, or connect to an external 12V battery. (Connectors included for both. See Specifications below.)
Don't forget to order a Wiring Harness! This energizer does not include a Wiring Harness (sold below), which connects leads and clips to attach to the fence and ground rod.
- 3 miles of 3 strand cattle fence
- 1-1/2 miles of a 5-7 strand sheep fence
- 18 of the 164' sheep/goat nets
- 9 of the 164' poultry nets
- Requires a grounding system. Inadequate grounding is the most common failure in an electric fence system. We recommend 3 ft. of grounding for this energizer.
- 12V DC draw: 210 mA/hr. With this energizer a 12V 100 ampere hour, deep cycle battery will last approximately 12 days* on a clean or a weedy fence. *Assumes being drawn down to 40% between recharges.
- To operate as a solar energizer, run the unit as a battery unit (DC) and attach a solar panel to charge the battery. (20-60 watt panel recommended.)
- 3 released joules
- 2.74 joules in moist soils
- 0.45 joules in dry soils
- Pulses per minute: 40
- 12V DC draw: 210 mA/hr
- Impedance type: low
- Input: AC/DC
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 MaxiShock 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.
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
- Make sure the power is turned off before working on the fence or the energizer.
- Make sure the fence line is clear of grass and debris that may lower the fence’s voltage.
- Ensure the solar panel is facing due south and avoid placing the unit where it may be covered by shadows from trees, bushes or tall grass.
- Regularly remove all debris from the solar panel.
- Batteries that are less than 40% charged may become damaged. Batteries MUST remain fully charged in freezing conditions.
- When using a 12V deep cycle battery, there is no case to protect the battery, so the battery will be exposed to the elements and risk of theft.
- This unit is not modular, therefore it is not repairable.
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.

Installed this fencer for new lambs to protect against wild dogs here in Puerto Rico. The fence is small, only 1300 feet long, but the weed pressure is great because everything grows so fast here. The old fencer was a half joule and keeping sheep and Great Pyrenees in but it only tickled you if you touched it and if my other dogs were quick they could get thru the fence without a shock because the spark wouldn’t jump the fur gap.
Wow, that is no longer a problem! This sucker will throw a spark a good 2 inches and speaking from experience, it is something you will not soon forget. My yard dogs no longer even want to go down the lane toward the fence as it zapped them hard the first time they got close.
Also purchased the digital voltmeter and it is awesome. No more guess work in bright sunshine about what the reading is and the ability to test the fence and the battery with one unit is wonderful.
I can’t imagine why you would need an energizer with more joules than this as it left me numb in the arm and chest as well as knocking me breathless after jumping a good six feet from the fence!

It’s working so far…

I have 7,000 feet of electric wire along a river. By fall the fence is covered with grass and willows. My old one joule charger was not strong enough. This patriot 3 joule charger delivers 4–6 thousand jolts through the vegetation.

Powerful energizer. Swapped out the intel. 2000 that was not keeping the pigs in for this and it did the trick. Hanging options could be better (as pointed out in other reviews). And no On/Off switch means it must be unplugged or unclipped from the battery to turn it off.

We started switching our old fencers to Patriot P30 Energizers as the old ones would fail about 5 years ago. We are now using the P30 on 100% of our fences "sheep ElectroNet " which range from 2 rolls of net to 20 rolls of net and the P30 Energizers have held up great with no problems at all they are very reasonably priced and trouble free! Thank you Premier Sheep for offering another great product that people can afford!
