Jackery Solar Panel Connector

This part does what its supposed to do and does it well. It remains to be seen how it performs over time outdoors, but from a functionality standpoint, it works as its supposed to. One note I have to deduct a star for is this part is ridiculously overpriced for being a relatively simple component. Even with ruggedized, over-engineered parts - which is a good thing - it should not be priced so high.

Our connector last for 2 uses b4 giving up the ghost. Most recently using it to run 2 panels to our 2000 Pro generator we had no input and an F7 fault code. Removing the connector from the system all together and plugging the panels individually directly into the generator*NPUT charging resumed. Not sure if there's a fuse or some other breaker inside the connector but whatever happened it has failed to connect 2 panels onto 1 connection to the generator

Great! Should I buy another solar panel since a third one can be connected. Would the third one put to much current into the Jackery battries?
