So you need to install electric fencing, but the choices are endless where do you start? Follow our step by step guide to choose and install the right fencing for you.
There are multiple products to choose from but making sure you choose the right one for you is essential.
Mains:
Perfect for where permanent electric fence is require, or when fencing large / multiple areas. They are always the preferred choice for any electric fence where a 230v supply is nearby as you don't have to change and charge batteries. The power can be taken from a mains energiser unit to the fence and the earth stake by insulated 'Lead Out Cable' which can be buried. This is usually a low cost insulated steel cable which has the ability to cope with high voltages and has minimal resistance. With a mains energiser, the running costs are very low with no maintenance required - you just switch them on and forget about them! A timer can be added to this set up to allow you control when they are on or off without having to go and manually press a switch. Being run on mains power alone can be risky if there is a power cut your fence will not be able to work until the mains power is back on. (Many of these units have the ability to be adapted for battery and or solar)
9v Battery Energiser
These energisers are powered by dry-cell 9v disposable batteries. They are very popular for strip grazing, small line fencing due to their mobility. The 9v batteries are usually non-rechargeable and you will need to check and then consider the cost of replacing the battery when it runs out.
12v Battery Energiser
This is perfect for semi-permanent electric fences or where mains power is not available. A rechargeable 12v battery (car/Leisure /battery) is used to power them. A good quality battery can generally power longer fences at a higher voltage than 9v energisers. A good quality car battery can be used, however a 'leisure' battery will proof better. Car batteries give out maximum power over a few days and then the power dwindles over the weeks, a leisure battery on the other hand is designed to give a steady output over the weeks and will then go from full strength to flat in a couple of days. This is known as 'deep discharging'. Please consider when buying a 12v leisure battery, the higher the Ah of the battery, the longer between recharges.
Compact solar energisers are energisers that have a 12v or 9v battery that is constantly charged by a solar panel. These energisers can come in a variety of shapes and sizes. They are available as one unit or they can come sealed in a lockable box with a solar panel on top and the battery and energiser separate inside the lock box. Solar is a benefit to open fields where there is a lot of natural sunlight and no mains power.
