I'm handicapped by only knowing English, but that device appears to be the correct item. Is that the same as this? If so, it's the right item.

P.S. I agree with pyromaster114 about the sizing of the system.

I'd suggest you make this... it is pretty simple. Off the shelf, the Solar Gens are going to break your budget quick and then no money left for solar.

https://www.youtube.com/watch?v=z-o9XSAfXTw Here's a good DIY. You don't have to have the lcd monitor.

The hardest part is predicting how much power you will need out there. Charging a phone is trivial, but lights can pull big power quick. So you'll need to figure out the lowest wattage you can run... 15watts * 6 hours/night * 5 days = 450Wh, so you'd need something like a 12v 35Ah battery if you don't have solar. BUT if you can get down to 5watts, you only need a 12Ah battery which is MUCH lighter.

So simplest would be a battery, ammo can, and a USB/12v with switch. (This would be like $70 battery, $20 for usb/switch, $12 ammo can)

If you want to charge with solar, you need a charge controller and panel. (Add to above $15 controller and $100-200 for solar panels)

I am in the process of finishing mine now and have elected to just use an external inverter for the off chance I need 120v.

Thanks for the responses.. I have ensured that the positive and negative are aligned the same between the lamps. I've connected to each with in sequence terminating at the controller.

This was my first attempt with a solar panel (20W).. Bought this : https://www.amazon.com/gp/product/B06XWTKYDC/ref=ppx_yo_dt_b_asin_title_o02_s01?ie=UTF8&psc=1

I see now that I should have purchased on with a variable load output. Any suggestions?

I would this work? https://www.amazon.com/dp/B07G4ZWX3F/ref=twister_B07JW87L4G?_encoding=UTF8&psc=1

Again thanks for the help.
