AKO Sun Power S 250 – solar electric fence energiser for self-sufficient paddocks

The AKO Sun Power S 250 energiser keeps your paddock fenced without relying on a mains socket. This compact solar fence energiser is ideal for horse paddocks and smaller fencing systems without vegetation, and works universally with all standard fences for horses, cattle, dogs and cats.

An intelligent battery management system with deep discharge protection keeps the unit running reliably even through long spells of bad weather: once battery voltage drops below 11.2 volts, the battery protects itself automatically (shown by a red flashing light). This gives you up to two weeks of runtime without sun and a long battery lifespan – with maintenance-free operation right through the main grazing season.
