Warning if wanting to chain multiple panels
The boulder 50 cones with cables to chain multiple panels in serial. Be warned that if you do this, as i did with 2 panels, the second panel only adds 5 to 10 watts of charging power. This was verified by a GZ tech who said " that is all you should expect." Apparently you need the 8mm combiner cable to connect in parallel to get better performance. It doesn't state this anywhere on the product description for the panel.

Yeti 150
I recently purchased a Yeti 150, Boulder 50, 2 sets of brackets, and a 15' 8mm extension cord, all to use in my truck camper. I got my order within a short time and in good condition. Love the Yeti 150, especially since our two day power outage this week. I had power to keep phones, tablets, and lights running with no problem. Looking forward to being off grid traveling on short trips soon. Very happy with the product and the ease of installing the panels on my truck camper.

Boulder 50 with Yeti 500, South Dakota.
I set the panel on my deck railing, facing south. The panel generated between 20 and 25 watts per hour.worked well with my Yeti 500.

Love my Boulder 50!
I love my Boulder 50 Solar Panel! It pairs well with my Yeti 500X power bank. I use it just to charge different devices (phones, speakers, computers, headphones) and it provides just enough power to do that!

Excellent Piece of Hardware
This panel is an excellent piece of hardware. Lightweight. Sturdy. Durable. I am absolutely in love with the tempered glass on the front. Mine has been through a Summer in North Alabama which includes hot, pollen, rain, wind, and even some bird droppings. It still works wonderfully. I do need to clean it a few times a month to keep it in good shape. Still, I believe it would operate under more negligence. I intend on buying another. I did buy the Boulder 100 Briefcase. Also incredible.

I have a Boulder 50 and a Yeti 400. I recently got a Renogy 160. Can I connect that to the 8mm input on the boulder 50 and then plug the 50 into the Yeti or would that exceed the max on the Yeti?

Can i plug in a Boulder 100 into the Boulder 50 so that I get 150watts? Or is it only like panels, such as two 50s or three 50s and instead I need to get the combiner cable?

I would like to combine my new Sherpa 100 with a Bolder 50. A reviewer stated, that if a cloud passes and the output of the Bolder temporary drops to zero, then the rest of the time the panels output will be shut off until it is replugged. Is that true?

I have 2 Boulder 50 panels linked together charging a yeti 400 lithium battery. When I plug in the solar panels in full Sun the unit beeps at me does not show any input W coming in and only shows Wattage coming in = the amount of wattage that's outgoing?
