How many joules for an electric fence, by species and distance: 2-4 J for cattle, 1-3.5 J for horses, 0.5 J for dogs, 0.25-1 J for poultry netting and 4.8-8 J for deer. Includes stored-versus-delivered joule data, the 1 to 12 joule classes, AC/DC and solar sizing, and MOQ from one unit.

A 2026 buyer's guide to the best electric fence charger: four decisions that settle the specification, the stored-versus-delivered joule gap, power source comparison, published coverage data and the certification pack importers should request. Includes a use-case shortlist from 0.25 J to 8 J, MOQ from one unit, and CE, RoHS, TÜV and SGS documentation.

Four HPS FENCE testers compared for dealers: 0–13 kV digital fault finder, 0–10 kV digital, mini pocket tester and multi-light indicator. Covers what a tester can and cannot measure, indicative voltage readings along a 3 km fence, and the resale bundle that prevents charger returns. MOQ one unit.

A dealer's guide to the best electric fence charger for cattle: the 2,000 V and 2–4 J targets, four charger types, five farm-size bands, and the earth-rod rule that prevents most voltage complaints. Includes HPS FENCE models from 2 J to 8 J, MOQ from one unit, and CE, RoHS, TÜV and SGS documentation for import.

Seven HPS FENCE energizers ranked by farm size, species and power source: 0.25–1 J for poultry netting, 3.5–4.8 J for cattle and horses, 3.5 J solar for remote paddocks. Includes delivered-versus-stored joule data, government species minima and dealer stocking guidance, with MOQ from one unit and CE, RoHS, TÜV and SGS documentation.

Five tests every energizer should pass before shipment: measured joule output, 72-hour ageing, box drop, IPX6 water ingress and final electrical inspection — plus what to ask for in a test report.

Horses need 1,500 V and visible tape, cattle 2,000 V and joules over distance, wooled sheep 3,000 V because wool insulates. A three-tier stocking model for agricultural dealers.

Seven checks that separate a real energizer manufacturer from a trading company: factory ownership, measured joule output, DoC signatory, batch testing, MOQ, warranty execution and spare parts.

A German dealer's checklist: which EU directives apply, the 12 documents to request, GPSR responsible-person rules, MOQ and territory terms, and the solar models that fit the German market.

Government baselines put the minimum at 2,000 V for cattle, 3,000 V for wooled sheep and 1,500 V for horses. For wholesale buyers, the task is specifying an energizer that still reads above those figures at the far end.

Energizer and charger are the same device. The difference that costs money is stored versus output joules, and our own range shows a 40% gap between the two figures.

IEC 60335-2-76 caps fence pulses at 5 J, 10 ms and 1 Hz. We compare that with published physiological thresholds, cattle learning data and field studies on predation losses to show where the real risks sit.

An energizer turns stored energy into short high-voltage pulses. Understand stored versus output joules, the three power options and how to size the unit before you buy wire.

An electric fence stays open until an animal touches it. Follow the pulse from capacitor to ground rod, and learn why voltage alone will not stop livestock.
