Patriot P20 Energizer
Use this 2 joule low-impedance charger for medium-length temporary and semi-permanent fences for livestock and wildlife. Also for medium-length permanent fences for cattle and horses.
Can be powered by either a 110v plug-in or 12v battery (sold separately under accessories 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.
Energizer Kits: Patriot P20 Plug-in Kit and Patriot P20 Battery Kit are available to help simplify your purchasing decision.

- 2.5 miles of 3 strand cattle fence
- 1 mile of a 5-7 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.
Can be used as a solar energizer
- See options under accessories tab above.
Benefits
Installation
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, or use the negative part of the Wiring Harness.
- Secure to ground rod(s) with a clamp.
- Plug into outlet and test fence.
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.
- Connect the energizer to the battery.
- Insert battery adapter into the Patriot unit. 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 should be serviced.
Troubleshooting
- Test the energizer first
- Turn off energizer.
- Disconnect ground wire and the fence wire.
- Turn energizer back on.
- With fence tester, put the ground probe (or clamp) to the ground terminal on the energizer and the metal loop (or positive clamp) at the top of the tester to the fence/positive terminal. The reading you get tells you how well the energizer is working without any other variables. If there is a very low voltage (under 4000v) or no voltage, then the energizer may have a problem. If the voltage is high (greater than 4000v) then the trouble lies with your fence. 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.
Precautions
- 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.
Warranty
It covers 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 after we have been able to examine the failed unit to determine the cause(s).

I will only purchase Patriot fence chargers. This is my fourth one (multiple fences in different areas) and they are a great value for the money. HIGHLY recommend.

The P20 is an economical and long lasting energizer. I accidentally left one out this past winter (in Wisconsin) and it is working just fine this spring. I have 6 of them now and use them on the sheep's electronet fences and the cattle's 3 wire fences.
