Thunderbird Solar Electric Fence Charging Kits can be attached to any Mains/Battery or 12V Battery Powered Electric Fence Energiser setup. By connecting these charging units to your 12 volt battery, you will keep the system topped up and your battery fresh and full of charge to keep your energiser operating around the clock.
If you are unsure which panel you require, a general starting rule of thumb is 10W worth of solar panel will work best for 10km or 1 Joule of energiser rating eg: A 20km or 2 joule energiser will use a 20watt solar panel. Battery size is generally double eg: A 30km or 3 joule energiser will use a 60Ah 12V battery.
Any 12V rechargable battery can be used
All Panels are 12 Volt and will charge any rechargeable 12v battery.
