Question: How well does it work in Northern areas of the USA that during winter are often overcast for days on end? We are in a valley area that makes our day light hours less intense or longer too. Thanks.
Document: I've used and gone through numerous solar fence chargers over the years, and none of them were of this quality. I've had this charger in place for over 28 days now, and due to its location, I can only get about 2-3 hours of sunlight per day. The charger is still reading good and I've seen it shock a cow or two recently. I couldn't be more pleased with the results. It's well made, and holds a charge longer than anything I've had before.
This is our first hot box and it is working great as long as it is grounded well....no brainer, really. We live in an area where we have 2 seasons....winter and summer and our summer is only 3 months. Even with overcast and lots of rain, this box has kept its charge!
ParMak makes the best solar chargers on the market. I have a large property with several different pasture areas. This is my third charger and they all work wonderfully.
I live in Maine and especially in winter we will have several cloudy days in a row. I have NEVER turned on this charger and had it less than a full charge. Never had issues with it grounding out, even when not set up properly (i.e., wrapped around a post instead of through an insulator).
I bet I could fence off a good part of my neighborhood with this charger if I wanted to.I don't have first hand knowledge of how this would work over a seriously large area so take it with a grain of salt, but for my application I feel that this charger is overkill to the point I'm going to set up some additional grazing areas for my goats, let my neighbor tie into it if he wants and use it to secure a half acre garden next year.
I simply purchased one 8 foot ground rod at The Home Depot and cut it in half. The meter on the front of the charger indicates the unit has full voltage at all times. However, the "incorrect" grounding might only work so well since we have a lot of sunny days in Florida. I highly recommend this charger and it is defiantly worth the money.
Product was easy install. Overall all it's very quiet and performs exactly as manufacturer states. Good to see a great product produced on the USA!Parmak, thanks for not outsourcing to another country.
I can't imagine being a deer and touching this wire with your nose lol. I'm sold! It also has never showed anything but a full charge/power even with several overcast days in a row.
This thing needs some sun. They pretty much come out of the box ready to go. But you do need to face it towards the sun. It needs full sunlight when it can get it. In order for the charge to last on those overcast days, weeks, etc...
After two, you couldn't turn the stud where it had been even with pliers. Still works, but it's nerve wracking trying to work on things when you have to very carefully disconnect the unit first. Construction quality was adequate.For the uninitiated, the number of miles thing is a bunch of hooey. I'd say this will do an adequate job of two wires less than 1500 feet. Beyond that, your animals had better already respect the fence cause they won't get trained by this one.
Answer: yes
