Bought may 16. I have used solar for many years, roof top and suitcase like this.ew fifth wheel, replaced the 2 12 v factory batteries in Paralell), with 4 6 volt flooded, in series , 2 6 volts in series to rplace the 12 volts. Hook the atem clips , pos to pos on 1 6 volt, neg from the atem to neg on the neg terminal of the other battery. controller flashes1 red battery light, the 2 green lights are on. no idea if this is good or bad, the included ino was pretty bare, no support other than the worthless amazon support black hole.So unless I learn the correct way to attach the atem suitcase solar to charge my batteries, I will return it, if you have the skills to figure this out, it may be a good product, but its to adavanced for me, or not working. after using suitcase solar for years, the 4 6 volts are beyond my knowledge.

So I got my panel today, got to test it right before a storm started rolling in. In a clear sky flat on the ground, I pulled 168 watts. Not bad for the conditions, but the setup is kind of puzzling. For some reason, they put their own version of Automotive 50 amp generic power pole connectors with their brand stamp on all the main parts, and then gave an adapter to a 30 amp connector. Why???? For starters, the connectors are obvious knockoffs, but more importantly they are totally unneeded. 200/12= 16 amps. Even if they use the same connector on the 300 watt panel, it’s only 25 amps. Instead I’d wasting all that space on the automotive sized connectors, they could have used smaller storm factor connectors and saved half the space o m the external storage bag. Thankfully, these giant connectors aren’t too hard to pull apart with a careful hand and a pair of pliers, and then you can put genuine 45 amp connectors in their place.
Once you mod that, you have a much better connection that is still overbuilt for the capability, but you end up with a half empty storage bag you can fill with other items.

I bought it for a trip out west and when I set it up the first time it didn’t work, NO output. Even tried to work it with another controller and it didn’t work, because although it said “compatible with a Jackery” It wasn’t. And now the return period is up!! VERY DISAPPOINTED

Work great câble to baterie is 10 feet long easy to cary u can put it anywhere where thé Sun is. Very happy of it

Not sure why all the bad reviews, I’ve had several similar panels and this one is actually an excellent panel, it’s mono, it’s sturdy and tests out really well! For those who don’t know much about panels, and it seems many of the bad reviewers don’t, you will most likely never get 120w out of any 120w Panel, the rating is only a best case senario and it would usually only happen if you brought it up to the thermosphere, with absolutely perfect conditions and zero atmospheric interference. Also, if they are calculating the total watts at the controller then you will definitely not get even close to 120w. This panel tests out well beyond where it should and yes the controller is cheap (it is not mppt), and I will never use it, but still a great value for theses panels.
NOTE: mine tested at 144.46 watts on a 45 degree sun, that’s pretty good! (see pictured attached)

I’ve tried 2 different charge controllers with these panels, and the most output I am able to get on a sunshiny day without clouds is about 30 watts. Very frustrating!

Had purchased another panel that I have been very happy with a different brand and controller, but not waterproof. Using that panel for portable/camping. In the meantime, I was looking for something that I could replace an older slower trickle charger that’s on the roof of the vehicle that doesn’t get driven as much anymore….decided to go with this one. The panel works well, but found that the controller was not working properly. Connected to the battery first and then the solar panel per all the instructions, the controller was not limiting the voltage output to the battery, it was trying to charge at 15.6~15.7volts. Super surprised…expecting it to regulate properly. After messing around with it for a while it finally settled down to 15.2V and was charging with ~1amp…, thought well I’ll keep a close eye on the battery and see if it switches to a float mode…NEVER happened….pulled it when it got the battery up to 15.0 V and said that’s it…. Didn’t want to kill a battery that is honestly only 6 months old.
Used another controller I have that I know works properly with this new panel and worked very well, brought the battery up correctly and sat at a normal float voltage (not temp correction setup). Though, easy….just a bad/controller problem. Didn’t want to deal with the hassle of returning/exchanging everything so provided what was done in the email and asked the seller to provide a new controller. Unfortunately they didn’t believe me and wanted photos showing full sun, with pictures of voltages on the meters on and on…I already spent a whole day messing around and didn’t wish to waste anymore time. Just decided to buy a new controller for 25 bucks …..disappointed the seller doesn’t trust the customer. I would have gladly sent back the old controller even. In any case, if the controller was more expensive I would have just exchanged the whole thing.
If you are using this panel be sure to check the voltage output at the controller box terminals and batteries….make sure it’s working properly or might eventually will likely have a bad day. Also the controller doesn’t have any visual readouts, so another bummer there, you have to use your own meters/tools….unless this controller is trying to do some fancy equalization charge, seems to be excessive voltage for charging a 12v car/truck lead acid battery.

Love it does a very good job of charging in a compact unit it does excellent has an awesome mppt controller way better than what I expected!

Solar panel works great and is made very well, MPPT never worked and after being sent a replacement I ended up buying a different one.

Nice value on good portable panels. Wish they had an integrated kickstand but that’s minor.

Doesn’t deliver 120W. The most I got out of it in full sun was 94W. However, I don’t think it was just this product: I’ve noticed that all solar panels promise more than they can deliver (including the big ones on my roof at home). They get away with this by using weasel words like “Nominal power” or “Max power”.
The cables that connect to the battery are too short. Had to prop the charge controller up on a box so the cables would connect. I think they are about 18″ long and would be better if they were more like 36″
Other than that, these panels worked flawlessly. I did end up changing the controller (which says in some places in the manual that it’s PWM and in other places, MPPT and other reviewers have said will overcharge your battery) with a Renogy MPPT controller which kept my 100AH battery charged and ready for the evening hours.
I like the way this folds up small and is easy to position on the roof of our class-B RV (or on the ground, depending on where the shade/sun is). It is heavy enough that a pretty strong wind did not move them off the roof of the RV!
Happy with the purchase for my intended use. I thought I would need more like 200W, but the 90W I’m getting from this is more than sufficient.

I ordered the product and it got damaged during shipping so Amazon cancelled the order. I reordered it and it arrived the next day. The panel came in a light cardboard box with no protective packing which is more than likely everyone’s issues with damaged panels. They are manufactured in Australia.
I hung my panel from a chain across the roof of my camper and hooked it up to my camper battery which was connected to a 1100-watt inverter. I ran my camper fridge and vent fan for 5 days without any issues. The battery was fully charged and the equipment ran fine. When I shut it down I noticed the controller was very hot. The manual said it needs to have ventilation around it but it cannot get wet. I mounted it inside a plastic jug with the bottom removed to allow cooling and keep it dry.

Je n’ai pas encore eu le temps de tester beaucoup, mais pour l’instant je suis très satisfait. Il recharge très bien ma batterie AGM 12V.
La qualité semble bonne par rapport au prix, et le panneau inclus un contrôleur MPPT, ce qui fait une grande différence par rapport à un contrôleur PWM.
Il est plus lourd que ce que j’avais pensé, mais semble assez résistant.
