J'ai un problème avec le contrôleur. Les panneaux solaires sont connectés selon un schéma 12V et le contrôleur (PWM) est inclus. Pendant les trois premiers jours, tout était normal (il lisait correctement 12-13,7 V), jusqu'à ce que je voie la tension passer de 20 V à 40 V avec des batteries complètement chargées. J'ai mesuré la tension réelle qui était de 13,7 V. De tels reportages me semblent anormaux. Je pensais que le contrôleur ne fonctionnait pas!

It should be 5 stars really because these panels are very effective, producing more power than similar non flexi panels. Unfortunately, as others have reported in their feedback, the items are inappropriately packaged. Both panels arrived damaged because the metal crocodile clips on wires included are just bashing the panels. There's no protection nor padding. Disappointing to see the supplier hasn't reacted to other customers with the same complaint. See in the photos the damage the metal clips have done to the panels.On the plus side, the seller made contact with me about the panels and is very keen to satisfy the customer. I didn't initiate contact with the seller. They pro-actively contacted me. On that basis I would suggest this seller is a safe bet.Anyway, the panels work well. They would work better if they weren't damaged as any damage causes a drop in voltage produced and it is the high voltage from solar that makes it work effectively. So not happy about loosing some solar panel power, but what they do produce is impressive. The panels are very flexible. Perfect for my application. Even though there are currently only 2 panels, during the sunny day they charge up the battery bank enough for me to run mains from batteries in the evening. I would like to add another two panels and will probably get matching ones from this seller.I haven't used the solar controller as I have a full mains inverter system already installed.

Arrived earlier than expected. Easy install . Packaged well , the wiring could probably do with being longer , other than that perfect.
