Hello together. I have bought the Noqon Solar Pad 120W. I now wanted to connect it to the Ecoflow River Max, but the Ecoflow does not react / charge.
Both the Noqon and the River Max have a socket for XT60 plugs. (On the Noqon it is clearly stated as an output, on the River Max it is clearly stated as an input). So I simply plugged the cables with the XT60 plugs into both devices and connected the cables in the middle via the male/female MC4 plugs, which should actually be correct? Except: Could the polarity possibly be wrong with this wiring and plus/minus reversed?
On the Noqon, the one red LED is lit, the one USB output supplies current, and when I measure the XT60 output of the Noqon with the voltmeter, I get between 15 and 25 volts, depending on the (current cloudy light). (That's all I can measure, but it's certainly not that the output of the Noqon doesn't work, unless there's something wrong with the current / power of the output). I will check later with the car charger if the XT60 input really works on the River Max. Does anyone else have an idea what I could be doing wrong? Or is there possibly a defect? (With the Noqon, it's also interesting that one USB output supplies power, but nothing happens with the other USB output...). And it's great that the Noqon doesn't come with any instructions / technical specifications...

Accepted Answer

I am not deleting my own question, but I am now answering it myself in order to possibly help other users, or another interesting question arises... 1) I was too impatient. After I tested it in cloudy weather and got >20 volts with the meter, but the Ecoflow River Max didn't charge, I thought of some defect. But I had nothing else to measure except the volts that came out, which of course is not conclusive.  2) I suspected it was the Ecoflow and tested it with the car charger cable with the XT60 cable, which worked. (Defective Ecoflow input socket ruled out.) 3) Plugged it in today in sunlight, it worked, Ecoflow charged with 10-50 watts (panel not optimally aligned).

But also interesting: Suddenly the charging power dropped sharply, although the panel was 90% in the sun. Now I noticed that there are two narrow strips along the entire panel at the edge of the solar cells, I haven't had time to google what exactly their function is. But if these two strips are not also in the sun, the output power drops rapidly, in the style of "panel is not in the sun, so less power". This may also have something to do with the charging management.

Sorry for the long texts: The bottom line is that the panel works and is tip-top. And it also works together with the Eco Flow River Max.
