What You'll Learn
Use a voltmeter to test voltage
To test a solar electric fence using a voltmeter, follow these steps:
Firstly, ensure you have a voltmeter designed to test electric fences. Electric fence voltmeters are specifically designed to detect voltage in electric fences, making them the most reliable tool for the job. Most models include a handheld meter with a digital readout and a metal prong on top, with an attached metal probe at the end of a wire.
Next, identify the ground wire. Refer to the owner's manual or manufacturer guidelines to determine the correct voltage range for your fence. Depending on the type of animals the fence is meant to control, electric fence voltages typically range from 2,000 to 10,000 volts. If the fence has two or more wires, one of them is likely the ground wire. If there is no ground wire, or you are unsure which wire it is, skip this step and proceed to the next step.
Now, touch the meter's probe to the ground wire. Keep your hand on the plastic or rubber section of the probe, not the metal tip, to avoid any accidental shocks. If there is no ground wire, stick the metal end of the probe several inches or centimetres deep into the soil.
Finally, while the fence is energised (powered on), place the voltmeter probe directly on the hot fence wires. The voltmeter will display the voltage readings. Compare these readings to the expected voltage range for your fence. If the readings fall below or vary significantly from the expected range, it indicates a potential problem.
Repeat this process at multiple points along the fence, including corners, gates, and areas where you suspect voltage issues, to ensure comprehensive testing.

Check the power source
To check the power source of your solar electric fence, you should first refer to the owner's manual or signage on the charger to determine the correct voltage range for your fence. Electric fence voltages typically range from 2,000 to 10,000 volts, depending on the type of animals they are meant to control.
Next, you will need to check if the power source for your energizer is properly connected and functioning. If you are using a battery, make sure it is charged, and if you are using an electrical outlet, confirm that it is supplying power. Look for any loose or damaged wires, connectors, or corrosion. If using an electrical outlet, check if a GFI outlet needs to be reset, or if a fuse or breaker blew.
If you are unsure how to troubleshoot your electric fence or energizer, review any installation, use, and maintenance instructions from your fence and energizer manufacturer. Many manufacturers are also willing to help their customers troubleshoot issues.
Once you have checked the power source, you can move on to testing the electric fence itself. Use a dedicated electric fence voltmeter to detect voltage in your electric fence. Most models include a handheld meter with a digital readout and a metal prong on the top, and an attached metal probe at the end of a wire. Point the meter at the fence constantly or at intervals of around 50-100 feet (15-30 m). If you get varying results, follow up with an electric fence voltmeter to see if you get variable voltage readings along the fence. Compare these readings to determine if they are within the expected range.
If you are still having trouble detecting the issue, try disconnecting any additional fences connected to your main fence to help narrow down where the problem exists. Then, test the electric fence again.

Test the grounding system
Testing the grounding system of an electric fence is crucial for its proper functioning. Here is a detailed, step-by-step guide to testing the grounding system of a solar electric fence:
Firstly, identify the ground wire. Refer to the owner's manual or charger signage to determine the correct voltage range for your fence. If there is a ground wire, use the manual to identify it. If there isn't a ground wire, proceed to the next step.
Secondly, install an earth stake and a load tester. Install a 2-metre earth stake as close as possible to the end of the fence. If you have a multi-wire fence, one of the wires is likely the ground wire. Install a 500-ohm load tester between a hot wire and the ground wire. Choose a damp area for the ground rod, as dry conditions may affect the test's reliability.
Thirdly, measure the voltage. Using a voltmeter, measure the voltage between the hot wire and the ground wire across the load tester. Keep your hand on the plastic or rubber section of the probe, avoiding the metal tip. Then, measure the voltage between the hot wire and an independent ground rod, leaving the load tester in place.
Finally, analyse the results. If the second voltage reading exceeds the first by more than 1000 volts, inspect the ground return wire for loose connections. If the voltage readings are variable or consistently below the expected range, it indicates a potential problem. A well-functioning electric fence should typically deliver a minimum voltage of 4,000 to 5,000 volts, and it should never drop below 2,000 volts.
Remember to test your grounding system at least once a year, especially during dry periods, to ensure the grounding capacity is sufficient.

Test the entire length of the fence
Testing the entire length of the fence is important to ensure that your solar electric fence is functioning properly. Here's a detailed guide to help you through the process:
Firstly, it is recommended to use a dedicated electric fence voltmeter for accurate results. Electric fence voltmeters are specifically designed to detect voltage in electric fences, making them reliable tools for the job. Most models feature a handheld meter with a digital display and a metal probe, which you will use to test the fence.
Now, walk alongside the entire length of the fence, staying within a distance of 3 to 5 feet (0.91 to 1.52 meters) from it. Keep the voltmeter pointed at the fence constantly, or at intervals of around 50 to 100 feet (15 to 30 meters). This will help you identify any sections with inconsistent power.
If you find sections that appear to be powered inconsistently, use the electric fence voltmeter to take voltage readings. Compare these readings to the expected voltage range for your fence, which can be found in the owner's manual or signage on the charger. A well-functioning electric fence should typically deliver a minimum voltage of 4,000 to 5,000 volts, and it should never drop below 2,000 volts.
By testing the entire length of the fence and comparing voltage readings, you can identify any problem areas and address them accordingly. This proactive approach ensures that your solar electric fence is functioning optimally and effectively serves its purpose.

Check for common issues
Electric fences are an excellent tool to keep your livestock on pasture, but they can be frustrating when they're not working correctly. Here are some common issues to look out for when troubleshooting your solar electric fence:
- Loss of power: This could be due to a faulty power source, a blown fuse, a tripped breaker, or a faulty energizer. Check if the power source is properly connected and functioning. If using a battery, ensure it is charged. If using an electrical outlet, check if it is supplying power and reset any GFI outlets if needed.
- Ground faults: Poor grounding is one of the most common issues with electric fences. Ensure your system has at least three ground rods, with additional rods in certain soil conditions. The ground system should be at least 33 feet (10 meters) away from electric or telephone ground systems to avoid interference. Keep the soil around the ground system moist as it conducts electricity better than dry soil.
- Animal interference: Wildlife or even your own livestock can cause fencing issues. Regular maintenance, inspections, and prompt repairs will help maintain the reliability of the fence.
- Faults: Grass, weeds, or overhanging branches touching the electric fence can cause faults. Broken insulators can also allow the electric fence wire to touch the fence post. Use a fault finder or a digital voltmeter to locate faults in the fence.
- Insulator issues: Insulators may be broken, allowing the electric fence wire to touch the fence post.
- Hot wire connection: Vegetation or brush touching the hot wire can cause issues.
