Parmak MAG12-SP combines solar charging with a long-range 12V battery system to power up to 30 miles of fence with a low-impedance design for efficient power transfer. It ships with a solar panel and a sealed 12V battery, ensuring continuous operation in sunny and cloudy conditions. The unit emphasizes high output consistency for remote locations and features strong impedance to minimize energy loss across long runs. Users should size grounds and posts appropriately to ensure reliable grounding and minimize stray currents.
Parmak MAG12-UO 12-Volt Magnum Low Impedance
Parmak MAG12-UO is a 12V, low-impedance charger designed for substantial ranges and robust fence performance. The unit targets up to 30 miles of fence with a compact form factor and a focus on dependable energy delivery. It is well-suited for larger properties or operations that rely on long, continuous fencing. When installing, ensure proper grounding and soil contact to maximize the energy transfer and reduce the risk of energy bottlenecks along the fence line.
Redants Electric Fence Charger 12V 12KV
Redants offers a compact 12V input with 12KV output and 2J stored energy, designed for wildlife control and livestock protection across 70 to 120 acres depending on terrain and weed conditions. The unit supports mains power, a 12V battery, or solar input for flexible deployment. It ships with warning signs and conductive wire, simplifying initial setup. For best results, follow the included mounting and grounding instructions to maintain a consistent fence pulse and avoid shorting or grounding issues.
Buying Guide: Key Purchase Considerations And Comparisons
When choosing a 12V electric fence energiser, consider the following factors to match your farm layout and security needs:
- Power output and energy storage: Higher joule ratings deliver stronger pulses, useful for long fences or areas with weeds. Low-impedance designs improve energy transfer along long runs.
- Range and coverage: Match the unit’s claimed range to your property size. Some models handle 10 miles, others reach 20–30 miles with long fences.
- Power options: AC mains, battery, and solar compatibility offer flexibility for remote or grid-free sites. A 2-in-1 or 3-in-1 design simplifies operation across locations.
- Grounding and soil conditions: Proper grounding increases system effectiveness. In dry soils or sandy soils, multiple grounding rods may be necessary.
- Ease of installation: Look for clear instructions, included ground hardware, and user-friendly indicators or LCD displays that simplify troubleshooting.
- Safety features: UL-certified adapters, pulse indicators, and door alarms or remote monitoring can enhance safety for operators and animals.
- Maintenance and durability: Weather resistance and robust housings help protect against outdoor conditions and livestock interaction.
- Accessories: Some kits include warning signs and wire, which can reduce initial setup costs and accelerate fence activation.
In practice, a 2-in-1 AC/DC option with solar compatibility is ideal for remote pastures and areas with limited electrical access. For larger properties or predator-prone regions, higher joule outputs and longer range models provide stronger deterrence. Ensure your chosen energiser matches the fence wire gauge, ground system, and post layout to maintain reliable performance across seasons.
