10 Best Solar Electric Fences 2025 in the United States

The Gallagher S400 Solar Electric Fence Charger is designed for medium-sized pastures, providing 4.0 joules of power which is suitable for containing livestock over a considerable distance. It can power a single wire fence up to 60 miles or multi-wire fences up to 20 miles, covering approximately 120-280 acres of land. This makes it a robust choice for livestock and pet containment in areas with unreliable or no access to mains power, thanks to its built-in solar panel and 12V battery.

The charger is portable and easy to install with its 360-degree mounting capability, which is handy for rotational grazing and wildlife exclusion. It also features multiple power modes to adjust the pulse rate based on livestock activity, and the battery can maintain power for up to two weeks without sunlight, adding to its reliability. The weather-resistant case and built-in lightning protection enhance its durability, making it a tough unit for outdoor use.

At 32 pounds, it might be on the heavier side, making it less convenient to move frequently. Additionally, while it includes a three-year warranty, potential buyers should weigh its weight before deciding.

The Andmon MINI400 20 Miles Solar Electric Fence Charger is a solid choice for those needing to manage electric fencing over large areas. The charger offers a decent power output of 0.3 joules, which is suitable for containing most livestock across up to 20 miles of fencing. Its solar panel, rated at 18.5V/3W, efficiently charges the 12V/4.5AH sealed lead acid battery, ensuring up to 14 days of operation without sunlight. This makes it reliable even in less sunny conditions, which is a notable advantage for areas with variable weather.

The device also performs well under extreme temperatures ranging from -20 to 80°C, and its IPX4 waterproof ASA outer casing adds to its durability, making it resistant to adverse weather conditions. Installation is straightforward, thanks to its compact size and included battery. On the downside, the 0.3 joules output may not be sufficient for more aggressive animals or for deterring wildlife, requiring users to consider their specific needs. Additionally, while the device is built to last, continuous exposure to harsh weather could eventually impact its longevity.

The product comes with a one-year warranty, providing some peace of mind regarding its quality and durability. In summary, the Andmon MINI400 is a reliable and durable solar electric fence charger ideal for smaller farms and standard livestock, though it may fall short for more demanding fencing needs.

The Gallagher MBS2800i electric fence charger is designed for large pastures and extensive fencing needs, capable of powering up to 250 miles of clean wire fence or 50 miles of multi-wire fencing. It delivers a strong power output of 28 joules, sufficient to maintain effective electric pulses over long distances and through fence faults, adapting its voltage to keep the fence energized even in challenging conditions. A notable feature is the flexibility in power sources: it can run on mains electricity, a 12V battery, or solar power, with the battery and solar panel sold separately, making it suitable for remote locations where mains power access is limited.

The charger includes modern smart features, allowing remote monitoring and control via a smartphone app and WiFi gateway, beneficial for busy farmers or ranchers wanting to keep tabs on their fences without being onsite. Gallagher products are known for their reliability and come with a three-year warranty, ensuring good weather resistance and build quality. Installation is generally straightforward, though some users may need basic electrical knowledge to connect the solar or battery options. The charger weighs about 11 pounds, making it portable enough for various setups.

One consideration is that the solar panel and battery are not included, requiring additional purchase and setup effort to run off-grid. Additionally, its higher price point may exceed the needs of casual users. This robust, high-capacity fence charger is well-suited for large farms or ranches that need reliable, flexible power options along with remote management capability.
