What you need to consider

Mains Energizers are designed for permanent installations where reliable mains power is available. Battery Energizers are designed for portable, temporary fencing solutions. Solar Energizers are designed for reliable power, all year round where mains power is unavailable or unreliable. Or for flexibility you can choose a Multi Powered Energizer which has all three power options.
Electric fencing systems tend to grow, so Gallagher recommends always purchasing an Energizer with more power than you require. More power also provides more confidence that the fence will perform despite unexpected shorts, like those created by vegetation growth.
