Eco Worthy 120 watt solar

Yep at 13.7v you're already fully charged so the charge controller is limiting output some. Pull the battery down overnight and then try it. You should get around 6.5-7 amps if it's completely clear and you point the module at the sun.

I have a question on this system.  After reading up a bit on this it looks like I need to add some fuses.  I would assume a 20 amp where it clamps to the battery?  10 amp from solar panel to controller?

Ok thanks.  I have a clamp on system so I will just put an inline fuse on positive clamp side.  I thought since the controller was a 20 amp that you would go with that.  Not sure of the guage of the clamp on wires I suspect they are 12 ga but I will have to check them.

I am just using the clamp on system that it came with the 12 volt connection isn't real long maybe 10 ft and I would just be adding an inline fuse to it.  The output wire for the panels is fairly long to give you enough room to set the panels where needed

  Reading the posts on solar panels got my interest enough to buy a Zamp 140 watt legacy portable solar panel. Amazon warehouse had it for $410.00 hope it arrives in good condition. My past experience with amazon warehouse has been mostly positive hope it continues that way when the solar panel arrives. We are hoping to use the solar panel more and our generator less. Zamp solar panels are considered pricey but for $410.00 I was willing to buy a Zamp and if it doesn't arrive in good working condition we can always return it free shipping for a full refund. The Zamp is also considered a little heavy hope too that is not a problem.                                                                                                                                  10/5/21     The solar panel arrived in very good condition I plugged it in to the Zamp connection on the camper and everything seems to work. It's heavy about 32 pounds but it is well built should out live me if I don't damage the solar panels and if the controller doesn't malfunction. I am 68 years old so the 32 pounds is a little heavy to be moving around I can do it but would rather it be a little lighter that's the only negative thing I can say about it. I set it on the propane tanks and let the top lean against the front of the camper and used a bungee strap to help secure it. I tried that to see if it works and I think in a rest area or parking lot can use it that way and have a bicycle lock that I can use for security locking the frame of solar panel to the trailer tongue. When not in use it folds and has a nice case for storage.
