BX600D has three ways to supply power：12 volts Battery/20w Solar panel/Adapter.Portable all-in-one unit arrives ready to power electric fence or netting.

electric fence chargers are able to reduce energy demand when the fence’s voltage is high–due to fewer weeds touching the fence.

This occurs in fall and winter for most fences and occurs all year for some horse, cattle and deer fences. As a result,battery is more likely to remain charged through the low sunlight days of autumn and winter.
