The best solar electric fence energisers, compared.
Top pick: Trsaow 1.2 J bullet Best value: Mekturm 0.2 J – About £105.99 is the lowest price in this set that still prints an output joule, 0.2 J. The sample is five reviews. Updated October 2026.
A solar electric fence energiser is an all-in-one pulse unit with a panel and a battery, for a fence that has no handy 230 V socket. The bullet says 1.2 J and does not say stored or output. Sheep in wool and long weedy lines sit outside this joule band. The [solar electric fence energiser buying guide](/hub/fencing-and-wire/solar-electric-fence-energiser/sub/solar-electric-fence-energiser-buying-guide) sets out joules, panel watts and what is actually in the box before you treat a kilometre title as the length through grass. A separate panel clipped to a 12 V leisure battery is a different product. A mains energiser is the usual choice when a socket is near the fence.

Question 1 of 2
What are you trying to hold?
Trsaow’s SUNDWL at about £109.99 prints 1.2 J and 12 kV in a bullet and does not say whether 1.2 J is stored energy or output. The title names a solar panel, and a spec line says 4 W, which is not clearly a panel rating. Across two amazon.co.uk reviews it sits at 5.0, and both are positive. One mentions a large panel in cloudy Scotland and no need to mains-charge. Neither review describes a fault. The included-components line says solar fence energizer, and an earth rod and a warning sign are not listed. The battery is stated as 6000 mAh, smaller than the 10400 mAh lines on several other units. Two reviews cannot carry a 10 km title.
Pros
Cons
Best for: You want the only listing in this set that prints a figure above 1 J, and you treat two reviews as a start rather than proof.
Less suitable: You need a labelled output joule, an earth rod in the box, or a sample larger than two.
Specifications
Common questions
Is 1.2 J stored energy or output energy?
The bullet says 1.2 J and 12 kV. The file does not also print a stored-energy figure, so you cannot treat 1.2 J as measured output from this comparison.
What is in the box besides the unit?
The included-components line says solar fence energizer. The title and a bullet also name an AC adapter. An earth rod and a warning sign are not listed.
How many UK reviews are there?
Two. Both are positive. One mentions a large panel in cloudy Scotland and no need to mains-charge. Neither review describes a fault.
Across 433 amazon.co.uk reviews, the My Animal Command MAC3ML sits at 4.4 and costs about £139.99. The listing states 0.25 J output and 0.55 J stored, a 6 W panel, a 12 V / 2 A UK plug, a 50 cm earth rod and a basic tester. Reviewers describe horses and a cob staying on the tape. One verified review says the sheep walked through the wire and that 0.25 J was not enough. The title length of 5 km is a clean-line claim, not a length through grass. Some buyers report months with no top-up, including in north-east Scotland, while others charge the unit as the days shorten. The notes for this listing also record failures around a year, followed by replacements. It is the only large UK sample in this set, and it is still a 0.25 J solar box.
Pros
Cons
Best for: You run horses or a cob on clean tape, with no socket at the paddock, and 0.25 J output is enough for that line.
Less suitable: Sheep in wool, a long weedy fence, or a line that UK sheep guides put nearer 3–5 J.
Specifications
Common questions
Does the box include a UK plug and an earth rod?
Yes. The listing includes a 12 V / 2 A UK plug wall adapter, a 50 cm earthing rod, and crocodile leads. A special-features line also names a basic kV tester.
What energy does the listing state?
0.25 joules output and 0.55 joules stored, with a pulse described as 9000–11000 V. The spec line says 10 kV. The title length is 5 km.
What do the UK reviews say about sheep?
One verified review says the sheep walked through the wire and that 0.25 J was not enough. Other reviews describe horses and a cob staying in. The star line is 4.4 from 433.
Mekturm’s J-SF001 lists 0.2 J and 8 kV at about £105.99, with a warning sign in the box and an IP55 claim. Panel watts are not stated, and the included list does not name an earth stake. Across five amazon.co.uk reviews it sits at 4.0. One report says a 16.2 hh horse stopped escaping. Another says the unit kept switching off and was returned after a month because the ponies got out. A bullet gives the size as 280 × 200 × 153.5 mm, while the dimensions line says 2.8 × 2 × 1.54 m, and the weight is 2 kg, so the metre line cannot be the housing. Five reviews cannot tell you whether the horse that stayed or the ponies that got out is the usual result. It is the lowest price in this set that still prints an output joule.
Pros
Cons
Best for: You want the lowest shelf price in this set that still prints an output joule, for a short horse line, and you will add an earth rod yourself.
Less suitable: You need a stated panel wattage, a UK earth rod in the box, or more than five reviews.
Specifications
Common questions
How big is the unit?
A bullet says 280 x 200 x 153.5 mm. The item-dimensions line says 2.8 x 2 x 1.54 m. Both are recorded. The weight line is 2 kg.
Does it include an earth rod?
The included-components line lists the unit, a power adapter, a warning sign, a cable connector, and a manual. An earth stake is not named. Mounting is described as a standard steel rod.
What do the five reviews say?
One report says a 16.2 hh horse stopped escaping. Another says the unit kept switching off and was returned after a month because the ponies got out. The star line is 4.0 from 5.
Trsaow’s SDWL2 at about £119.99 states 0.2 J and a 3 W panel, and the title also says 10 miles and 30 acres. Across three amazon.co.uk reviews it sits at 3.8. One says it kept the horses out. One verified review says it was not robust enough for equestrian fencing and that the battery held no charge from the mains, so the unit was abandoned. The included-components line says manual, while the title and the bullets also name the panel, a 10400 mAh battery and a charger. An earth rod is not listed, and voltage is not stated. At this price it costs more than the Mekturm unit that also prints 0.2 J, and more than the other Trsaow listing that prints 1.2 J. Three reviews leave both the horse that stayed and the dead battery on the table.
Pros
Cons
Best for: You already have an earth rod and you only want a 0.2 J solar box if the battery accepts a mains charge.
Less suitable: You want a UK plug named as such, a larger review sample, or a stated output above 0.2 J.
Specifications
Common questions
What does the included-components line list?
It says manual. The title and the bullets also name a 3 W panel, a 10400 mAh battery, and a charger. An earth rod is not listed.
What length does the title claim?
10 miles, and the title also says 30 acres. Output is stated as 0.2 J. Voltage is not stated. The mile claim is not a length through grass.
What do the three reviews say?
One says it kept the horses out. One verified review says it was not robust enough for equestrian fencing and that the battery held no charge from the mains, so the unit was abandoned. The star line is 3.8 from 3.
ATMOREA’s SG-TT-P18 is the lowest price in this set at about £51.36. The title says 8 kV, a 3 W panel and a 10000 mAh battery, and it claims 3 miles. Joules are not stated anywhere on the specification. The star line is 3.4 from 24, and every review block in the saved listing is labelled United States, so that text is not UK experience. A review mentions 0.2 J, which is not a specification line. The technical details say batteries included: No and batteries required: No, which conflicts with the title. An earth rod is not named. You cannot line its output up against the 0.25 J units, because the listing never prints joules.
Pros
Cons
Best for: You are pricing a small garden or poultry net and you will confirm the joules with the seller before you rely on the fence.
Less suitable: You need a printed output joule, a UK review, or a horse or sheep fence.
Specifications
Common questions
How many joules is it?
The listing does not state joules. It states 8 kV and a 3 mile length. A review mentions 0.2 J, which is not a specification line.
Is the battery included?
The title says a 10000 mAh lithium battery and a 3 W panel. The technical-details line says batteries included: No and batteries required: No. Those lines are not resolved.
Are the written reviews from the UK?
The star line on the amazon.co.uk file is 3.4 from 24. Every review block in the saved listing is labelled United States. There is no United Kingdom review block in that file.
The JKLESA unit at about £115.99 prints 0.25 J in the bullets and 0.2 J in the highlight, with a 6 W panel and a UK plug. Across 10 amazon.co.uk reviews it sits at 3.2. The bullets name an earth rod, and one of those reviews says no grounding pin was supplied. The same small sample includes a unit dead after six months, two that switched off while charged, and one return after an overnight charge showed no life. Other reviews describe a strong pulse on a horse fence. IP54 and IP55 are both printed, so the weather claim is not a single figure. Ten reviews are too few to treat the star line as a settled result, and the two joule figures mean you cannot quote one output.
Pros
Cons
Best for: You already accept a conflicting joule line and only want a horse unit if the earth pin is actually in the box.
Less suitable: You want one printed output figure, a confirmed earth rod, or a review sample larger than ten.
Specifications
Common questions
Is the output 0.25 J or 0.2 J?
The bullets say 0.25 joules. The item highlight says 0.2 J. Both figures are in the same amazon.co.uk file and are not averaged.
Is an earth rod included?
The bullets name an earthing rod and crocodile connectors. One of the ten UK reviews says no grounding pin was supplied.
What failed in the reviews?
Among ten reviews: a unit dead after six months, two units that switched off while charged, and one return after an overnight charge showed no life. Other reviews describe a strong pulse on a horse fence.
Six amazon.co.uk solar electric fence energiser listings were scored on the star line and the size of that sample, on whether the listing prints an output joule, a panel wattage, a UK plug and an earth rod, on faults named in the reviews, and on the shelf price in GBP against those printed figures. Weights are Amazon evidence 25, stated specification 30, review outcome 25 and value 20. Prices are the figures stored on 19 October 2026. This is not a laboratory test. None of the six listings prints BS EN IEC 60335-2-76.
Amazon evidence
25%Star rating on amazon.co.uk, then the size of the sample. A 4.4 from 433 is stronger evidence than a 5.0 from 2. Review text labelled United States does not count as a UK sample.
Stated specification
30%A labelled output joule, a panel wattage, a UK plug and an earth rod. Two joule figures, two IP ratings, a size in millimetres and in metres, or a battery line that contradicts the title, lose this block. An unlabelled 1.2 J does not outrank a listing that prints both output and stored energy.
Review outcome
25%A sheep walk-through, a unit dead within months, a switch-off, a missing earth pin, or a battery that would not take a mains charge are deductions. Two positive reviews with no fault stay positive, and they stay a sample of two.
Value
20%Shelf price in GBP against the figures the listing actually prints. The lowest price does not take this block while joules are missing. The lowest price among units that print an output joule takes best value. That is Mekturm at about £105.99. The thin sample stays in the score.
Choose the supply and the animal before the price. A solar all-in-one is for a fence with no handy 230 V socket. A mains unit is the usual choice when a socket is already there. A separate panel on a 12 V leisure battery is a different product. Then keep one output joule the listing actually labels, the panel watts, and whether a UK plug and an earth rod are in the box. Shelf prices below were stored on 19 October 2026.
A solar electric fence energiser is an all-in-one pulse unit: a panel, a battery and the pulse circuit in one housing. You use it where the fence has no handy 230 V socket. A separate panel clipped to a 12 V leisure battery is a different product. A mains energiser is the usual choice when a socket is near the fence. The six amazon.co.uk listings kept here, with prices stored on 19 October 2026, run from about £51.36 to about £139.99.
A title of 5 km, 10 km or 10 miles is not the length you will power through grass. Score the printed joules, the panel and the earth, not the distance in the title.
Stored energy is larger than output. My Animal Command prints 0.55 J stored and 0.25 J output. An unlabelled 1.2 J, or a review mention of 0.2 J, is not the same claim.
UK guidance used here says a panel covers three seasons and the dark months still need a charge. Some reviews report months without a top-up. That is not a rule for a UK winter.
The first figure to keep is output joules, not the distance in the title. Stored energy is the larger number when a listing prints both. My Animal Command is the only unit here that does: 0.25 J output and 0.55 J stored, at about £139.99. Mekturm and the Trsaow SDWL2 print 0.2 J. JKLESA prints 0.25 J in the bullets and 0.2 J in the highlight. The Trsaow SUNDWL bullet says 1.2 J and does not say stored or output. ATMOREA states 8 kV and a 3 mile claim and does not state joules.
Panel watts and a way to top up the battery are the winter question. This set prints 3 W on ATMOREA and on Trsaow SDWL2, and 6 W on My Animal Command and JKLESA. Mekturm does not state panel watts. A 4 W line on the other Trsaow unit is not clearly the panel. UK sellers say a panel covers three seasons and the dark months still need a charge. My Animal Command reviews split between months with no top-up, including north-east Scotland, and a charge as the days shorten. Then read the box.
Three typical situations, each with a recommendation from this comparison.
You run horses or a cob on clean tape, with no socket at the paddock, and 0.25 J output is enough for that line. The My Animal Command MAC3ML at about £139.99 prints 0.25 J output, 0.55 J stored, a 6 W panel, a UK plug and a 50 cm earth rod, at 4.4 from 433 reviews. One verified review says sheep walked through.
You want the lowest shelf price in this set that still prints an output joule, for a short horse line, and you will add an earth rod yourself. Mekturm J-SF001 is about £105.99, with 0.2 J and 8 kV printed, at 4.0 from 5 reviews. Panel watts and the plug type are not stated. One review describes a return after the ponies got out.
A garden or poultry net sits in the under-1 J band in the specialist starting points. ATMOREA is about £51.36, with 8 kV and a 3 W panel in the title, and joules are not stated. Confirm the joules with the seller before you rely on the fence. The written reviews in the file are labelled United States.
The top pick is the My Animal Command MAC3ML at about £139.99. It is the highest score because the UK sample, 4.4 from 433 reviews, and the labelled joules are both present: 0.25 J output and 0.55 J stored, with a 6 W panel, a UK plug and a 50 cm earth rod. It is still a 0.25 J unit, and one verified review says sheep walked through. The best value is the Mekturm J-SF001 at about £105.99, the lowest shelf price among units that print an output joule (0.2 J), from five reviews. ATMOREA at about £51.36 is cheaper and does not take that award, because the listing does not state joules.
Mekturm 0.2 J
About £105.99 is the lowest price in this set that still prints an output joule, 0.2 J. The sample is five reviews.
