Solar Lithium Technology

• Lithium iron phosphate battery and high efficiency solar panel provide superior and continuous product operation, with a maximum output voltage of 10kV

Faster Charging, Long-Lasting Battery Performance

• An internal heavy-duty lithium battery and a highly efficient 12 w solar panel provide superior, long-lasting, self-sufficient power on your fence line, day and night

Intelligent Adaptive Energy Control

• Smart adaptive electronics are constantly monitoring the solar energy being stored, measuring it against the battery voltage and adjusting the output energy to ensure your fence is powered for as long as possible - even in the absence of sunlight
• Energizer pulse intervals and voltage output reduces as the battery state of charge drops below 30%

Multiple Power Options To Suit Your Fencing Application

• Two operating modes ensure optimum battery management and animal control specific to your fencing requirements
• Livestock Control Mode: Operates with a fast pulse during the day and slower pulse at night for when domestic animals are less active
• Wildlife Control Mode: Operates with a fast pulse day and night with reduced power output to conserve battery voltage

Protected Circuitry and Battery Longevity

• Dual insulated plastic enclosure protects internal circuitry and lithium batteries from extreme temperatures

Confidence in Every Fence

• Pulse Peace of mind, built in. Lithium Solar Fence Energizers are backed by a 3-years warranty, including the battery-reliability is not in question
