VOSS.farming "KAPPA 7 SOLAR", powerful energiser complete with 12 W solar panel + 12 Ah lead-acid rechargeable battery

The lead-acid battery powers the energiser via environmentally friendly solar energy.

Why choose an electric fence energiser from VOSS.farming?

We have 35 years' experience in the electric fence business and know how important it is to use a reliable energiser. That's why we sell exclusively high-quality branded devices made in Germany – by VOSS.farming. Naturally all our energisers fulfil the stringent European safety standard EN60335. Because we're convinced of the quality, reliability and safety or our devices, we're happy to offer you a 3-year warranty on all our energisers. And if you should still have any problems or questions, our professional workshop and our advice team will be happy to help you.

The VOSS.farming "KAPPA 7 SOLAR" 9 V electric fence solar kit is so interesting.

This practical and sophisticated solar kit has a high shock strength of 10.500 volts and a shock power of 0.48 joules. The energiser is equipped with monitor SMDs for checking the energiser, the battery and the fence. This means you are always well informed about the status of the fence and the battery. The energiser has a high output voltage and a high discharge energy. It is suitable for medium-length fences with little vegetation. You can use it to keep various types of animals, such as chickens, pigs, cattle, ponies and horses. The lead-acid battery is located in the energiser housing and is connected to the solar unit and the energiser. The energiser is suitable for mobile use and ideal for field work. The package also includes various connection cables and a grounding post.

So that the solar unit functions reliably without maintenance, we use a larger lead-acid battery than most of our competitors. The 12 Ah lead-acid battery is a brand-name product – an AGM rechargeable battery – and has been specially optimised for this purpose. On the top side of the lead-acid battery there is a charge controller, this prevents the battery from overloading.

The energy for the lead-acid battery is delivered by the 12-watt solar panel. This is delivered with sturdy brackets and connection cables. All the necessary screws are included for assembly of the unit. The solar panel cable connects directly to the charge controller. It is child's play to attach it with a screwdriver.

With this kit, you can operate the battery-powered energiser without maintenance during the entire summer season. For winter grazing, we recommend charging the battery at regular intervals. There is no need to buy any batteries. This electric fence solar unit will pay itself off after only a short time.


Although you do not need to buy and dispose of batteries, you would still require to recharge the battery time to time when there is not sufficient sun. For this purpose we have a special mains charger avaialble in our shop (Art: 44232.UK), which is specifically designed for batteries with low capacity.

Facts about the AGM rechargeable battery:

AGM stands for Absorbent Glass Mat, which means the same as lead-acid. A fibreglass mat is soaked with sulphuric acid. Unlike conventional electric fence batteries, the AGM battery has no liquid that could leak out. The AGM battery's passive discharge is low due to its comparatively low interior resistance. Even if you don't use it for a longer period of time, you will still have sufficient capacity to keep your animals. This is especially significant if you don't need the energiser during the winter, because it can be used again immediately in the spring. An AGM battery is less sensitive to deep discharge. It also provides a good capacity in cold temperatures, which is not always the case with normal lead-acid batteries. The lifespan of an AGM battery is also longer.

IMPORTANT: this energiser is not sutiable for use with electric fence nettings.

Please note:

9 V batteries are NOT rechargeable. Their life can be prolonged when using a solar system, however once depleted they should be replaced with new ones. Please dispose of your old batteries responsibly by disposing of them for FREE at your local Recycle centre, thanks to our participation in the Distributor Take Back Scheme.
