That was it exactly, and I don't know why I didn't think of it. I disable it all the time for news sites. All the text links open perfectly here, but they aren't blocked like the image links are. Thanks.

That's a decent price. Did you check out any reliability videos before purchase ?
I measured it. But typically a decent 100W 12V panel will put out 17V - 18V at about 5A - 5.5A at peak. Measured of course before the controller. Your controller converts the the voltage to the needs of your battery. Wire size is always a function of voltage and amps (power (W) = A * V). They are related. Compare a chart for 12V and 24V and for the same Amperage and you will see what I mean.
You mentioned you like to use charts for determining wire size. Make sure you are using the out and back distance for the length unless the chart specifies it has already done it for you (ie: if your length is 25 foot from solar panel to battery you would use 50ft.)
To be honest I almost sent this wire back as I had several in my wish list and I thought I had picked a silicone jacketed wire. After inspecting the wire I was surprised at its softness and flexibility. I am very confident of it. Even so, I do have a short piece laying full time in the sun.

have been on trailer for several months .work great. super light no frame used 3m body trim tape to stick to roof . has several grommets to tie down . what i got 100W 18V Flexible Solar Panel Kit RV Boat Car Roof for 12V Battery Power Charger | eBay

This is exactly the kind of cable I'm looking for, can you please tell me where you found it?
Edit: Found it, ouch, expensive, over half the cost of the panel I bought LOL!

You are the only one who has mentioned out and back length. I think it is an import omission by all of the utube video demonstrations I have watched. Being a building designer I always play on the side of caution when it is a safety issue.
The charts I have found and use do not tell me that either. Thanks for that important bit of info.

Yep, and not very flexible, either. It was cheaper with free shipping when I bought it to experiment with. It's meant for exposed, wet or dry, installation for static panels.

I suspect it may take a year or two, or more to really degrade, if in fact it does. If it doesn't, it's a great solution for DIY solar. I know one vendor sells two types of extension wire and states one is more flexible but not as long lasting, the other is more rigid but does much better exposed continually.

Out of curiosity, I wonder if there is a chemical that could be applied to the exterior shielding sleeve on the 10-2 exterior wire to protect it and give it a longer life at the same time. Something like they put on tires to keep them from cracking.

I'm going to check locally this weekend, sometimes in cabling you can find something locally that will work just as good or better. Lots of power cables around for landscaping and things like that made for the outdoors, just need to find something that is 10 gauge! Might stop in at Tractor Supply too, you never know! I'll update if I find something!

Yeah, cool. I looked everywhere for awhile and couldn't find anything that wasn't outrageously expensive, so went with the separate, stiff, 10AWG. Landscape cable is meant to be buried usually, in my experience, and okay for wet, but not exposed to the weather.
Hope you find something and let us all know.

Good thought, though you'd have to find out just what type of sheathing you're working with and then probably apply it once or twice a year. Though, come to think of it, I already have an excellent spray from 303 that is specifically for UV Protection for vinyl, rubber, plastic and fiberglas, etc. 303 UV Protectant Spray .
Now the nerd in me wants to have two 12" samples of several different wire types out in the sun for a year. One each of the different types as control, one each with 303 UV Protectant.

I just added a dual AGM battery system and 170 amp alternator to my Gen 3 4Runner. I went with the Hard Kore 200 amp solar panels running through a Redarc Manager30 and Wagen PureSine 1000 watt inverter. I also added a Dometic PLB40 as a backup. I don't have a huge power draw, but I usually run solo and try to be as prepared as I can. The largest single continuous draw, which is actually pretty low, is the Dometic CFX95DZW fridge. So far I'm extremely happy with this part of my build! I'm new to this forum concept and don't know how to add pictures yet so bear with me...

I went with this. Once I get my trailer and group 31 battery, i'll look this up and let it do its work to keep everything charged. I added pigtails to my truck, car, motorcycle, and soon to be trailer for the standard battery tender so this was an easy choice.

LMAO!!! I told you I was new to this forum stuff. I just realized these things appear in reverse chronological order. My post above was in response to an inquiry that displayed 8 pages ago from 10JUL19. Sorry for my blundering into an area that has nothing to do with my reply. I'm trying folks, just learning as I go.

If you press the reply button it will put the post you're referencing in quotes above. Just FYI
Wow, see there. Thank you so much, I never noticed that before. Your guidance is greatly appreciated. This is only the 3rd or 4th time I've responded to anything. Mostly just read and learn. No wonder I didn't get in the feedback loop before.
