Solar Energisers
No power at the fence line? A solar energiser with a built-in battery runs off-grid all year round, which makes it the default choice for paddocks away from the house and blocks without mains power. Panel, battery and energiser come as one sealed unit: mount it facing north, connect the fence and earth, and it looks after itself.
Weighing it up? Read Solar or mains? for the trade-offs in plain English.
