Solar IntelliShock® 120 Energizer & Kit
High-output solar powered 1.2 joule energizer. Portable all-in-one unit arrives ready to power electric fence or netting.
IntelliShock® electric fence chargers are able to reduce energy demand when the fence’s voltage is high–due to fewer weeds touching the fence. This occurs in fall and winter for most fences and occurs all year for some horse, cattle and deer fences. As a result, an IntelliShock unit’s battery is more likely to remain charged through the low sunlight days of autumn and winter.
New! For added charging capability during winter use in Northern locations, the 120X arrives with a 20 watt solar panel.
Note: Kit includes a 5-Light Wireless Fence Tester.
Solar powered energizers are a popular choice when 110V power is not easily accessible. Attached solar panel will recharge the batteries on sunny days.
- New for 2020! External 110V adapter port for faster plug-in connections for recharging.
- Solar panel is easy to adjust for seasonal light availability.
- Easily accessible fence and ground terminals. Fence and ground wiring harness included.
- External 110V port allows the energizer to be operated without a battery and plugged into a 110V power source.
- Large capacity batteries for increased life during long periods with low sunlight.
- Features a 20 watt solar panel for optimal performance in Northern locations.
- Highly visible on/off light with low battery indicator.
- Won’t rust. Made from durable UV-treated polycarbonate.

How to Use
Using 10mm wrench, remove the bolts holding the solar panel in place and replace with the supplied knobs (shipped inside the unit).
Use the wiring harness to connect the energizer to the ground rod and fence.
- Unscrew the red terminal knob.
- Secure the bare end of the wire with the orange clip into the hole behind the red terminal knob.
- Replace the red terminal knob and tighten.
- Repeat steps #1-3 for the black ground terminal.
- Connect the black clip to the ground rod.
- Connect the orange clip to the fence.
- Turn energizer on. (When switching on, make sure the power button is pressed all the way in.)
- Check the voltage to ensure the fence is properly electrified before introducing animals.
Optimal Solar Orientation and Placement
Correct placement of the energizer and solar panel is critical to the best operation of the unit.
1. Position the energizer so that the solar panel faces due south. This will allow the panel to receive the maximum amount of sunlight possible even during the low-light days of winter. Consider the sun’s movement throughout the day and avoid placing the unit where it may be covered by shadows from trees, bushes or tall grass.
2. Determine the correct tilt angle for the solar panel. The sun’s position above the horizon will change from season to season. As a general recommendation, an angle of 50° is optimal for the longest use in most areas of the continental USA. However, the ability of the solar panel to recharge the battery can be maximized by making angle adjustments each season as shown in the illustrations below.
In the far northern USA from November until February, there may not be enough hours of sunlight to fully recharge the battery. Charge the battery externally when the battery indicator light flashes green/red or red.
3. Regularly remove all debris from the solar panel. This includes grass clippings, dust (especially on gravel roads), leaves and snow as this will reduce the solar panel’s ability to recharge the battery.
How-to Use a Wireless Fence TesterFor Fence:
- Touch the top of the tester to the electrified fence you wish to test.
- Push the button.
- The tester will light up according to the voltage at that location on the fence.
- Turn off energizer.
- Disconnect ground wire and fence wire from energizer.
- Turn on energizer.
- Touch the top of the tester onto the top of the fence terminal on the energizer.
- Push the button.
- The tester should light up to 6000 volts or more.
- 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.
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.
To determine if the fault is with the fence or the energizer…
- Turn off energizer.
- Disconnect ground wire and the fence wire.
- Turn energizer back on.
- Using a fence tester, determine the output voltage of the energizer. If the voltage is below 4000V, then the energizer may have a problem. If the voltage is above 4000V, then the trouble lies with your fence or ground system.
If the energizer is faulty…
- Test each battery with a Digital Battery Meter or other multi-meter.
- If the meter reading is greater than 12.5 volts, then check the terminal connections to ensure they are clean from corrosion and fastened tightly.
- If the meter reading is less than 12.5 volts, then use the included 110V power supply to recharge each battery separately. See instruction manual for details.
- Ensure the ground system (rods/stakes) is installed and connected correctly according to the instructions for this unit.
- If you continue to experience problems, please call us at 800-282-6631.
If the fence is at fault…
- Walk or drive along the fence looking for any point in which the energized wires touch the soil, a steel post, a steel wire or anything conductive.
- Look for damaged insulators.
- With electric netting, the problem can often be traced to excessive weed load. Starting at the fence charger, measure the voltage as you walk along the fence. If you find a gradual decline in voltage, then you may need to clean away the grass or other debris from the lower strands. If the voltage drop is more rapid, then look for a hot wire touching the metal stake at the bottom of the plastic posts.
- 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 turning off or disconnecting sections of fence. When the voltage on the remaining fence rises sharply, you've located the section(s) causing the problem.
- The alternative is to begin at the energizer 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.
- If you continue to experience problems, please call us at 800-282-6631.
Tips to preserve battery life:
- Turn off the unit. Disconnecting the unit from the fence is not sufficient, the unit will still pulse unless it is turned off.
- Clean off the solar panel. Dust and debris may have accumulated during use and as a result prevents the panel from maximum electrical production.
- When the energizer is not being used, store the unit indoors at room temperature and out of the sun. Do not let the energizer sit in the sun for an extended period when it is turned OFF as this could damage the battery.
- When not in use, ensure the battery stays above 40% charged. Lead acid batteries don’t work well when they’re left discharged, or at a low charge, for long periods of time. Periodically recharge the battery in the sun or with the included 110V charging unit. Stop charging when the battery indicator light flashes GREEN. Do not overcharge the battery.
30-day warranty for all batteries.

Although the IntelliShock is a good product, I can only give the 120 model 4 stars, as the 10W solar panel is undersized for continuous use of the 1.2 Joule energizer. My recommendation is to either get the IntelliShock 60 (I also have this one and gave it 5 stars, as it has worked flawlessly) or the IntelliShock 120X which doubles the solar recharge rate with a 20W panel.
Initially my 120 seemed fine, but now in November in southern MD it is flashing green/red indicating low state of charge. This is despite relatively ordinary use. We are using anywhere from 1-4 sections of net fencing, on moist ground, with very little losses to weeds/grass touching. Meanwhile, my 60 is working fine on the same applications and has always flashed green, indicating normal state of charge. Also, the difference between the 0.6J shock and the 1.2J shock on the animals, including goats and pigs (and curious dogs) is indiscernible. Not to say the difference isn't real, but the extra juice isn't needed for our setup. If we ever run super-long fences we will appreciate the 1.2J shock, I suppose.
I ordered a 20W solar panel to upgrade my 120 essentially to a 120X. You have to call for that, the panel alone isn't listed online. The tech rep indicated the issue is not unusual for the 120. I suppose there are some folks far south who will have success with the 120, but most should use the 60 or the 120X instead. There is no substitute for doubling the recharge rate relative to the energy discharged in the continuous pulsing.
Great company, excellent products and support overall, but I think you will see the 120 phased out in favor of the 120X eventually. Note the 180 model (1.8J) uses a 30W panel. They've obviously figured out the right ratio.

Good little charger. I am running 4 rolls of 164' 35" sheep net and this thing keeps it hot even with a heavy grass load. Very portable, easy to set up, and I didn't have to bring it in at all during October to recharge, even running it 24 hours a day. Should easily stay hot through the summer months.
One thing I did notice is that the AC adapter port does not seem to be well protected from weather and the lid has a tenancy to trap precipitation. So far no issues with this but time will tell.

The 120X is so far doing great. I can only assume it will be as good as the IntelliShock 60. Which I’ve been using 12 hrs a day for 3 years. Holds a charge great. Customer service is excellent.
