FarmNix Solar Electric Fence Charger — 20 Mile 2J, Adjustable 6–12KV, 18Ah Battery

FarmNix 20 Miles 2J Solar Powered Electric Fence charger delivers adjustable 6KV–12KV output with up to 2.0 joules and a 20-mile effective range for reliable perimeter control.

This solar fence energizer combines a 6W panel with a built-in 18Ah lithium battery to keep fences powered day and night with minimal maintenance. Cold- and heat-tolerant and rated IP55 for outdoor use, it supports multiple voltage settings so you can match pulse strength to the animals or wildlife you need to deter. The unit is compact, quick to install and includes essential accessories to get your fence running fast.

How do I choose the right output setting for my livestock or predator deterrence?

Select the output voltage based on the size and toughness of the animals you’re controlling: lower settings for small livestock, higher settings for larger or persistent predators. Start at a conservative setting and increase only as needed while following local safety guidelines. The 1-second pulse interval provides consistent, repeatable deterrence without continuous current flow.

• 6KV–8KV: suited to small animals like sheep, goats and garden pests
• 10KV: for cattle, horses and medium livestock
• 12KV: for larger predators and tougher intruder challenges
• Energy options 0.3–2.0J let you balance impact and battery life

What installation steps are required and how long does setup take?

Installation is designed to be straightforward: mount the main unit in a sheltered spot (a protective box is recommended), attach the 6W solar panel, connect the grounding rods and live wire using the rotatable terminal screws. Typical setup takes just a few minutes for someone comfortable with basic fence hardware.

• Mount main unit and solar panel where sun exposure is good
• Connect grounding rods and live fence wire with supplied screws
• Charge 12 hours before first use until green power indicator lights
• Package includes adapter, input/output cable, screws and warning sign

How does the system perform in bad weather and during low sunlight?

The FarmNix charger is rated IP55 and operates between -20 °C and +60 °C, making it resilient to rain, snow and heat. The 18Ah lithium battery stores energy from the 6W solar panel to maintain 24-hour operation through variable light conditions. For longevity, storing the main unit in an additional protective box reduces exposure to direct elements.

• IP55 waterproof rating for outdoor durability
• Built-in 18Ah battery offers uninterrupted night operation
• Works in wide temperature range: -20 °C to +60 °C
• Recommended protective box extends device lifespan

What safety and maintenance tips should I follow?

Always follow the warm reminders: charge the device until the power LED turns green before first use, and ensure voltage remains above 3.2V. If external force or disassembly triggers the protection mode, a full charge usually restores normal operation. Regular visual checks and keeping the solar panel clean will maximize performance.

• Charge 12 hours before first activation; indicator must be green
• Do not operate below 3.2V—recharge to reactivate protection mode
• Keep solar panel clear of debris and mount main unit in sheltered spot
• Inspect terminal connections and warning sign placement periodically

Who is this for: Farmers, ranchers, gardeners and landowners who need a low-maintenance, solar-powered fence energizer with adjustable strength for a variety of animals and wildlife. It’s suited to properties requiring up to 20 miles of effective coverage and users who want a weather-tolerant, battery-backed system that’s quick to install and easy to adjust.
