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 recharging capability during winter use in Northern locations, the 120X arrives with a 20 watt solar panel.
Note: Kit includes a Digital Tester (for testing fence voltage and 12V battery voltage.)
Solar powered energizers are a popular choice when 110V power is not easily accessible. Attached solar panel will recharge the batteries on sunny days.
- 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 pre-drilled 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.
- 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.
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
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.

Hasn’t worked correctly since we got it. This is our 3rd solar charger in the last 10 years, the others worked fine. We had to purchase this larger one as we’ve added additional netting, but this is our first of this brand. Several phone calls to customer service, purchased a multi-meter for testing, and it all “tests fine”. Holds a charge for an average of 4-5 days before we have to bring it inside for 72 hours to charge. Customer service said that a charged battery alone should work for 4-5 days and recommended that we purchase an additional battery. So what’s the point of the solar panel if I’m not getting any additional days even in sunny weather in the summer?

Excellent portable fence charger. Set it up 1st day and nothing but clouds and rain for 3 days. It was putting out 7.7K volts 1st day, 3rd day with no sun still at 4.4K. It’s a good feeling to not depend on the grid to keep our animals safe. Will do well on our homestead.

Just ok—I really miss the suitcase style energizers. These are not great and disappointing if you’re familiar with the old metal encased energizers. They will power a fence, but are not particularly durable. The handle is unusuable once the solar panel is attached, the panel adjuster knobs are flimsy and the on/off button is in the wrong spot. These are fine if you don’t need to move them much, but if you’re looking for a durable energizer for an intensive grazing operation I would look for an alternative.

Very easy to set up and easier to use. I really appreciate just having to push one button and not having to disconnect anything. High quality and powerful. The coyotes are in for a big shock after they got used to pushing down the fence when it had a cheaper, less powerful charger on it

Worst assembly instructions ever. The solar panel is very fragile. As I tried to figure out how to attach panel legs ended up scratching panel on floor. Need to assemble on a soft surface like a carpet.
