Dual-Power Energizers: Switch Easily Between Battery and Mains

Dual-Power Energizers: One Unit for Two Power Sources

A dual-power energizer can run either on 230 volts from a socket or on a 12V rechargeable battery. That is handy when your animals move between fields near the yard and more distant grazing over the course of the year. You simply take the unit with you and connect it to whichever power source is available on site. Some models can also be supplied by solar power or a battery pack.

Typical Uses

In spring the energizer often stands at the stable and supplies the paddock, while in summer it moves out to the summer grazing and runs on a battery there. If the mains supply fails, you just connect the battery and the fence stays live. For livery yards and farms with several fields, a dual-power unit saves buying a second energizer. Some models also offer an LTE or app connection that lets you check the fence remotely.

Choosing the Battery and Accessories

For battery operation you need a suitable 12V battery, ideally a leak-proof AGM battery with enough capacity. A solar panel lets you recharge it out in the field. For mains operation, a mains adapter is included or available depending on the model. In both cases the same applies: without good earthing and clean connections, even the most powerful energizer loses effectiveness.

Frequently asked questions

What is the difference between a dual-power and a 12V energizer?
A pure 12V unit only runs on a battery. A dual-power energizer can also be connected to 230 volts, which makes it more versatile. If you never move your grazing, a unit with a single power source is often enough.

Does a dual-power energizer switch to battery automatically in a power cut?
That depends on the model. With many units you change the power source yourself by connecting the battery. If you keep a charged battery in reserve, the fence is live again in no time.

Do I need different earthing on mains than on battery?
No, earthing is equally important in both cases. Drive several earth stakes into moist soil at each location. When you change fields, take the earthing with you or set up a new one on site.
