One of the problems with electric fencing is that it is often far from mains power. A typical electric fence battery weighs 20-25kg and will last 2-6 weeks, depending on its capacity and the type energiser being used. When the battery needs to be recharged, the fence is not electrified. To stop this, many people are now switching to solar, by connecting a solar panel to the battery, or buying a dedicated solar energiser, such as the P80S or P500S. Read our solar help section.
Using a solar panel to 'trickle charge' the electric fence battery, so that it never (or rarely) needs to be charged using a mains charger. In addition to a range of solar panels that can be retro-fitted to any 12V electric fence system, the Hotline Falcon P500S and Helios P80S have been specifically designed as a self-contained solar electric fence energiser.
Essentially, solar panels can be used to power any size of fence energiser, including mains operated ones (in conjunction with a 240V inverter). The only difference is that you need to use larger panels. Also, many professional energisers, such as the Hotline Phoenix range, have a 12V battery backup option and can, in fact be used exclusively at 12V, making them ideal for solar power.
