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.

  No Weeds Light Weeds Heavy Weeds
Steel Wire 5 miles 2.5 miles -
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.

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

I set up my polywire, ...
Jun 8, 2023
I set up my polywire, 4-strand fence and installed my solar fence charger. I left the charger off for 4 days in the sun to charge and this evening turned it on. I tested the fence and a current was running through it for about 2 min. After that, the system seemed to shut down, although the led display indicated that a charge was being sent. I tested the system and not current was flowing through it. I am very disappointed and have seen other posts that report the same experience. it appears that the battery is the problem, but for a newly installed system, I should not have to be concerned with this matter.

Going on my 5th year with this. In the beginning, we had to replace the batteries twice. Zareba did that with no hassle at all. It still runs at full power, and helps keep deer out of our orchard. Would buy again without a doubt.

I've had it for five ...
Nov 8, 2021
I've had it for five years. Twice it has quit charging the fence while the light continued to flash. The battery was bad (5.8v), the problem fixed with a new battery. I consider this a significant design flaw. After the first time, it was "I'll remember to check it." After the second time I put black tape over the light so it wouldn't fool me again. The minor issue is what I consider poor labels. I have "crs disease" which is "Can't Remember Stuff." So I added labels using felt markers that use oil based paints ("paint pen") which resist fading better than Sharpies. On the bottom and front I have "On-OFF" labels for the switch. On the bottom screw holes for the battery compartment I have "battery (with arrow pointing)" and "2.5mm hex" for the screw size. I also have "bad at < 6.0v" to remind me when to change. If I hadn't noticed the light not working at night, I never would have found it wasn't working at all- it did OK during the day with the sun sending enough electricity to make the light work (but not charging the fence). I don't recommend this product until the design flaw is changed. Otherwise, works fine.

Service was outstanding!
Jun 30, 2021
Purchased the Zareba ESP5M-Z from another online dealer and it was DOA. After installation around my vegetable garden, I thought I was protected from raccoons, groundhogs, and other small varmints. A few days after installation, my sweet corn was being destroyed by coons. Purchased a tester and discovered the "hot" wire was not even warm! There was absolutely no output from the wire terminals on the charger. Called Zareba customer service, and they were extremely helpful. Sent the unit to Woodstream for repair with an expected 5-7 business days turn-around. Shipped out on Thursday. The following Tuesday, it was returned. I installed it, and testing showed 7,000+ volts all around my garden. No more coon damage! Many thanks to Zareba and Woodstream.

Worked continuously for 4 years
Mar 17, 2021
I've had the 5-mile charger for 4 years and the battery has just now quit holding a charge. It will still work during the day if we have sun. For some of you that said it was flashing but no volt going out? I found when it was super dry the ground rod needed water. Once I watered the ground pole I could hear volts going through the lines. So might not always be the battery, it could be the ground. I am going to replace the battery and hope it continues to work as well as it did for the last 4 years.

Good product
May 23, 2020
I have had this unit for over 6 years and it is still working great. I did replace the battery but I also replaced the battery in many devices like my cordless drill. If you leave a battery it will self discharge and then if it gets to low on charge it may not take a charge again. Sorry to hear some people had issues but for me I would buy another one if this one ever dies.

Not happy
Aug 14, 2019
Very upset with this product... Unit did not work.. immediately keeps sending a charge as soon as I hooked it up to the battery, and would not stop... second unit did the same.. battery was a healthy 12.8V DC. Don’t understand what the issue could be..Instructions very vague and Customer service was absolutely no help.. and of course.. warranty ran out 3 weeks ago.

Would Not Recommend
Aug 9, 2019
Used the 5 mile solar fence charger to contain my dogs in the back yard. Worked great for almost 2 years and then just quit. No light no nothing. Tractor Supply was no help at all, told me abruptly to just contact the manufacturer. I would not recommend this product. Used as it was it should of lasted considerably longer than almost 2 years.

This was so perfect for keeping the neighbors dogs out of my yard and keeping my chickens safe. It was also very simple to hookup for a beginner in electric fencing.
