Lets just say this is my first solar panel and charge controller bought for my micro-camper trailer, a TAG. When received from UPS the box was flattened and was unsure if panel, etc. would be in workable condition. After opening this very thin and semi-flexible panel it did have one corner slightly turned in. So I was unsure if it would work. Got the instructions out and poured over them trying to understand what the procedure was for setting up. Actually it is pretty easy once you get your wires connected properly (I substituted my #12 wires for the thin versions with unit). I used my own 12 gage wires and connectors so as to not modify any of the parts if I had to return panel due to improper shipping container. After doing what I read to keep a short length of wire from controller to battery and making the longer length from the panel to the controller I did not notice that one should always plug controller into battery before connecting panel. Testing with only controller connected to panel yielded nothing. Once I reread and found the "order" of connection with battery to controller first and got my wiring proper to + and -, and was out in sun, Panel and charging came to life! I saw as high as 20+ volts from panel o charge controller and around 2.4 amps. Charge controller did its job of not overcharging battery when up to 13.8 volts So I feel this will work as needed in keeping the battery up to snuff in non-connected shore power camping events. I will just have to make sure to watch the battery level when discharging with on-board fan and 12 volt cooler and lights. Did see over 13.8 volts to controller even with cloud cover.

Panel itself is very light and protective 'outside" cover works well. But as panel heats up in sun exposer it gets more flexible, so you might consider making a "stand" to support it that can be also folded for storage. I also have added a thin towel to between the panels when it is folded for storage to avoid panels rubbing against each other. While testing I used a digital volt meter to insure proper use and connections--a must.

I have since mounted charge controller in protective and water tight Tupperware clear tub to lid of trailer outside accessory box near the solar connection on outside of trailer. Wiring and controller are contained inside accessory box until needed and then run the connections for charging. Solar charge controller can be viewed when trailer accessory lid is open through clear top of Tupperware container or as top is removed for better clarity. Used 3M red auto accessory double-sided accessory tape to supplement mounting Tupperware to trailer accessory box lid.

I have used this for emergencies. Although fragile in it being flexible, it charges batteries from electronics to vehicle! It’s great to have on hand in areas where the power goes out often. Or camping or even in your car!

This thing has been hitting about 75-90watts in the full sun. I think its a little floppy but when it's leaning on the RV is did great. it charged my 500w power station to 100% in about 4.5hours from 26%. It also charged the battery in the RV the next so it lasts longer on our trip. I have ordered another one to charge both at the same time. best bang for the buck. Thank you.

Everything is done well, fast delivery
