ANDMON MINI160 Solar Electric Fence Charger — 0.16J, 2‑mile range, weatherproof with sealed battery

The ANDMON MINI160 is a compact, weatherproof solar electric fence charger that delivers a 0.16 joule stored pulse (0.11 J output) to protect up to two miles of fencing for livestock with day/night energy-saving modes.

Designed for small to medium pastures, the MINI160 combines a solar panel, sealed 12V/4.5AH battery and dual DC/solar power options into a single, easy-to-mount unit. Its low-impedance circuit maintains pulse effectiveness across multiple wire strands and variable fence conditions, while the built-in NIGHT mode reduces pulse frequency after dark to conserve energy. The unit is intended for outdoor use, tolerates rough weather, and fits on common post types including Y, T and wooden posts.

How much fence can the MINI160 realistically power?

The MINI160 is rated to energize up to two miles of fence, though actual coverage depends on wire type, number of strands and fence grounding. Heavier, multi-strand fences or poor grounding reduce range; simple single-wire setups will achieve maximum distance.

• Stored energy: 0.16 joule; usable output: 0.11 joule.
• Typical capacity: up to 2 miles on light, well-grounded single-wire fences.
• Range decreases with more strands, high-resistance wire, or weak ground systems.

What are the power and battery features I should know about?

The charger runs from its built-in solar panel charging a sealed 12V/4.5AH lead-acid battery, and it accepts an external DC charger when needed. If regularly charged by sunlight, the unit can operate for long stretches; when sunshine is limited the battery backup will keep the fence live for days.

• Sealed 12V/4.5AH battery included (battery shipped disconnected for safety).
• Operates up to about 28 days without sunshine under light load conditions.
• Accepts an optional DC charger for non-sunny installations or faster recharge.

How does NIGHT mode and pulse timing improve performance?

NIGHT mode reduces pulse frequency after dark to save energy and extend battery life, while keeping animals aware of the fence. The charger shifts between a daytime pulse schedule and a slower nighttime interval automatically.

• Daytime pulse interval: approximately every 1.5 seconds.
• Nighttime pulse interval: approximately every 2.9 seconds.
• Lower pulse rate at night reduces battery drain without removing deterrent effect.

What should I know about installation and durability?

Installation is straightforward: mount the unit to a Y/T or wooden post, connect the output and earth leads, then attach the internal battery leads (red to positive, black to negative). The housing is built to tolerate outdoor conditions and typical farm use, but following the connection instructions is critical for safe operation.

• Mounting compatible with Y, T and wooden posts for versatile placement.
• Internal battery shipped disconnected — open cover and connect red to +, black to - before use.
• Low-impedance design helps maintain pulse strength under load and in damp conditions.

Who this is for: The ANDMON MINI160 is aimed at farmers, hobby homesteaders and landowners who need a portable, low-maintenance electric fence energizer for pigs, sheep, goats, horses and cattle in remote or off-grid areas. It fits smaller pastures and rotational paddocks where a compact solar-powered unit with battery backup and simple mounting is preferred over larger mains-powered chargers.
