VOSS.farming "NVi 9000" mains energiser – a powerhouse for the most difficult fencing situations

This very powerful mains energiser is ideal for long fences, extreme vegetation and defending against wild animals.

Why choose an electric fence energiser from VOSS.farming?

With over 35 years experience in the electric fence industry we know how important a reliable energiser is. That's why we sell high-quality VOSS.farming energisers which are made in Germany or EU. All VOSS.farming energisers come with a 3 year warranty. Finally, when you buy VOSS.farming, you buy professional electric fence equipment directly from the manufacturer. By cutting out the middle man we can offer you better quality at a lower price.

VOSS.farming "NVi 9000"

11,200 volts together with 11 joules make the "NVi 9000" especially suitable for long fences and heavy vegetation, because even in these situations you can rely on this energiser to keep your fence secure. The recommended fence length is 70 km without vegetation, but under optimum conditions it can also be used for very long fences, up to 230 km.

The energiser is equipped with 3 very bright LED lights that will show you fence state, grounding and consumption. It has an alarm function which immediately becomes audible if an animal or a person are in constant contact with a fence. This allows continuous monitoring of your electric fence and protects your animals. In case of a constant contact, the energiser will slow its pulse sequence, which will protect the animal from severe harm.

With VOSS.farming "NVi 9000" you can attach 2 separate fence systems to the energiser at the same time thanks to 2 fence outputs with different power levels. The "NVi 9000" has a high output energy, but still low energy consumption. The energiser is easy to operate and maintain. It is highly suitable for keeping horse, goats, sheep, pigs, cattle, highland cattle, deer, wolves, foxes and wild boars.
