does the positive polarity of the cable have to match the positive polarity of the solar panel?
with the ecoflow panel 160 watts, plus goes to minus! i have connected the plugs but there is no signal! maybe the problem is the polarity?

Hello extensa5
Don't get too confused by + and -. 
In the second to last diagram, the black conductor is labelled + and the red one -. This is wrong.

If you plug everything together as mechanically possible, it will be fine. 
Then wait until the sun shines on the panel and the battery will start to charge.

Answer

Hello
The polarity must be observed, the cables are usually assembled in such a way that this is normally correct. If you use the original cables, then it must fit. Connecting the solar panel to Ecoflow, for example, can be done directly without any other components and the power of the panel can be read and optimally adjusted via the APP. You will need a solar controller to connect to a battery.

Answer

Hello, you have to respect the polarities: red is always positive and black negative. Don't rely on diagrams, there are sometimes mistakes.
