Full shock strength even with heavy vegetation: AKO Duo Power Xi 8000 electric fence energiser

The AKO Duo Power Xi 8000 is an electric fence energiser for 230 V mains power and 12 V battery with 11,7 joules of stored energy. It safely contains sheep, bulls and horses and keeps wolves and wild boar away from your pasture. You can use it at the stable just as well as on far-off paddocks.

On mains the energiser runs without battery changes, on the pasture a 12 V battery powers it, with solar support if you wish. With the High/Low switch you choose between full and reduced power. The multi-colour LED bar display shows you the fence voltage from a distance, and a separate LED warns of a low battery. The deep discharge protection protects your 12 V battery.

Overview:

  • Safe for sheep, goats and cattle in winter coat: under load there are still 8.700 V on the fence, at least 4.000 V is recommended
  • Power reserve with grass and branches on the wire: 7,8 joules per pulse ensure a noticeable shock, even when vegetation lowers the voltage
  • Fence length up to 50 km without vegetation, up to 17 km with medium and up to 7 km with heavy vegetation
  • Cheap on mains: depending on level and fence load around 6 to 21 euros a year (at 35 cents per kWh)
  • Long run time on battery: a 100 Ah battery lasts around one week at full load, up to almost four weeks at low load
  • Good earthing with 3 earth rods of 2 m or 6 rods of 1 m in moist ground, at least 3 m apart and at least 10 m from buildings
  • Short electric pulses: unpleasant but harmless; with longer contact the energiser slows the pulse rate; put up a warning sign along public paths

Questions & answers:

Can I simply connect my car battery?
Better not permanently. A car battery is built for short, strong starting currents and copes poorly with deep discharging on an electric fence. Use a deep-cycle 12 V battery with around 100 Ah that you recharge regularly.

How many volts do I need on the fence against wolves?
At least 4.000 V should be present at every point of the fence, including the furthest point. Under load the Xi 8000 still delivers 8.700 V and so has plenty of reserve for long nets and polywire. Measure the voltage regularly with a fence tester, especially when grass grows back.

Why isn't one earth rod enough for this energiser?
The stronger the pulse, the more earthing the energiser needs, otherwise the energy fizzles out and the shock on the fence becomes weak. Drive 3 earth rods of 2 m deep into moist ground and connect them to each other. In dry or sandy ground, additional or longer rods help.

    AKO Galvanised Ground Rod 1 m, Special Earth Stake

    Galvanised ground rod 1 m – reliable earthing for your electric fence The AKO ground rod provides reliable earthing for your paddock or electric fence system. Made from hot-dip galvanised T-steel, it is exceptionally robust and weather-resistant, making it ideal for permanent outdoor use. Thanks to the M6 stainless steel screw, the earth connection cable can be fitted quickly and securely. Additional M8 and M12 drill holes allow the connection of earth cables with a wire terminal clamp, giving flexibility for different connection systems. It provides the foundation for reliable containment on horse, cattle, sheep and goat pastures. Overview: Reliable earthing for electric and paddock fences Hot-dip galvanised T-steel resists corrosion permanently M6 stainless steel screw for the earth connection cable Additional M8 and M12 drill holes for wire terminal clamp Suitable for horse, cattle, sheep and goat pastures Easy to drive into moist soil Technical Data: Length: 100 cm Width: 3 cm Height/profile: 2.5 cm Weight: approx. 1.4 kg Material: hot-dip galvanised T-steel Connection: M6 stainless steel screw, plus M8 and M12 drill hole Scope of Delivery: 1x galvanised ground rod, 1 m1x M6 stainless steel screw FAQ: How deep should I drive the ground rod?Drive it as deep as possible into moist soil, as this closes the electrical circuit most effectively. How many ground rods do I need?When using several rods, keep a distance of at least 3 metres between each one. Why should the ground rod be galvanised?Rust has an insulating effect and hinders the voltage return to the fence energiser – galvanised steel prevents this.
