Note:ย Deep cycle type batteries are recommended. Solar panel sizes may vary due to geographical locations. Larger panels may be required in some areas.

*Energiser distances are a guide only. Factors such as proximity of live wire(s) to earth or to other parts of a fence, distance of live wire run underground, thickness of wire and earth condition will affect the effective distance. Thunderbird recommend a minimum distance of 200mm between the live wire(s) and any other conductor, otherwise effective energiser distance is reduced.
