Charger Distance Ratings

The amount of fence line that your Zareba® charger can operate depends on several factors, including the type of fence line you’re choosing. Steel wire, for example, carries power further along the fence line than poly fencing. This fence is ideal for light weed or no weed conditions. Vegetation, weeds, and fallen tree branches may limit the distance electricity can be carried along a fence line. Ensure your fence is working to the best of its ability by regularly walking the fence line to check for disturbances.

Polywire 2.5 miles 1.25 miles -

Solar Power Built to Last

To prepare your charger for use, switch the on/off button to the “off” position and allow it to receive 3 days of sunlight. After that, the charger is ready to use! The solar panel is designed to store solar energy that will last up to 2 weeks without sunlight. Enjoy the most powerful solar-powered charger made in the USA.

Easy-Grip Knobs

Connecting your fence is simple with the easy-grip knobs on your 5-mile solar Zareba® charger. Attach the fence’s ground wire to the post with the green knob and the live hot wire to the red knob. Remember to turn your charger off before making any connecting wire adjustments and then turn it back on so it continues to gather solar energy. Knobs are designed to be under the charger to reduce exposure to the elements. The durable cabinet protects the circuitry from weather extremes.

Solar Charger Installation Guide

To properly install your Zareba® electric fence charger, charge it first by exposing it to the sun for 72 hours. After that, mount it and attach connections as directed.

Your charger includes a number of features to make installation easy, including:

  • No outlets necessary – Place anywhere on your property.
  • Easy-grip terminal knobs, color-coded for easy wiring.
  • Install on t-posts, wood posts, or flat walls.
  • Optionally, install through hanging holes built-in the heavy-duty case
  • Power indicator light to monitor charger status
  • Note: that every fence system needs a charger along with posts, insulators, and fence wire or poly fencing to be fully functional

Product Questions

Can the battery be charged with a charger
Question by: Mark Bateman on Mar 21, 2020, 8:00 PM
This battery can be charged with a trickle charger. Just make sure it is for the correct voltage! This will allow you to charge the battery in approximately 12-18 hours.
Answer by: Woodstream (Admin) on Mar 22, 2020, 8:00 PM
In order to recharge the solar unit does the power switch need to be in the "on" position and does the ground wire need to be grounded, or does it just need to be placed in a sunny location?
Question by: Joan in Bethlehem, PA on Apr 26, 2018, 8:00 PM
To charge the unit, we recommend disconnecting the energizer from the fence and grounding wires. The unit should be placed in the sun, in the off position, for three full days.
