Review: Works great! Only needs one grounding rod! - Just an update that might help someone on this last one that I installed. I used the copper grounding rod, again only one Rod needed, versus the Galvanized steel rod that I used on my first fence. The copper gives a better energy to the fence, it gives a better shock. Obviously nothing that’s gonna hurt any of the animals. My horse is terrified of the fence even if there’s not an electric fence charger attached to it. But keeping out other animals, dear raccoons etc. I just feel that the copper rod performs much better. I’ve dabbled with electric fences, both solar and electric over the last few years never being actually very successful due to the multiple rods. I was a little skeptical when I read this one only needed the one grounding rod and that’s it. There’s a wire with a large alligator clip at the end that attaches to the box itself and then it clipped right into the fence. It is true, it does work exactly that way. You need get a grounding rod from Lowe’s or Home Depot pound it into the ground, I did mine with about 4 foot left above the ground, attached the electric fence box, tighten the end to the box onto the pole, screw the nut and wire onto the back of the box, then clip it onto the tape, cord or wire whichever you put up and you have a working electric fence. Quick and easy. I actually just bought a second one for another area on my property that’s very far away. Probably would work but I don’t want to run that much fencing or poles. You have to put it a sunny place just like any other solar items, even when we had about a week of cloudy rainy days it had no problem with holding a charge. It worked every day. I highly recommend this electric fence option
Review: Great unit, one year later with no issues - I've had this electric fence energized for nearly a year and it has work flawlessly the entire time. I am using this to protect a grove of fruit trees from my local neighborhood deer who will eat nearly every plant in my yard. This electric fence energizer has kept the deer out completely. I have 5 strands of wire, approximately 75' long each. The solar aspect is great and has kept me from having to run power out to the fence. Another great aspect is that the grounding rod acts as the support for the energizer and has an alligator clip from the positive and just clips on to the wire. I never have turned the unit off, just simply disconnect the alligator clip and address my trees. Highly recommended and will most likely buy another once I get another garden set up

## Questions & Answers

**Q: I need to know if this will work on a chain link fence. After much research online I can't get an answer. Will it work on chain link fence?**
A: I doubt it will make the electrical connection needed for a continuous loop, and lots of places for grounding to happen

**Q: Can this charger be used with wire fencing?**
A: Yes, it can be used with any type of electric fence wire.  Thanks for your question.

**Q: im running two runs top and bottom of fence  2200 feet of wire thru 3 spring gates in a continuous run and all i need is one ground rod?**
A: In order to get the best current flow which=the max shock the charger can produce, you need a good ground. if the ground rod is deep enough and the dirt is moist you would get good current flow from the charger. If not, another rod would in theory be like driving a longer rod. You don't want any weeds or branches to touch the hot wires either, they will weaken the shock. Is each wire 2200 feet, or all wires total 2200 feet?  all wires should be totaled.  More wire increases the voltage drop. ! mile = 5280 feet. The fence tester should help. Connect one wire to the charger and see if it gives a high reading on the tester. then add another and test then another and another to see if the current is still high. That should help answer the need for more ground rods. During dry soil conditions, i pour a bucket or two of water over the ground wire.

**Q: How long does the battery last and is it replaceable?  I have an older solar charger and it costs more to replace the battery than the charger.**
A: I expect the battery to last for years, though at some point find myself in your same situation but, by then batteries will charge faster and last even longer.
