* It was an issue with the 250 grounding.
Hi.
Finally been able to install the 250.
Testing the setup with a 100W panel from my neighbours, I had to realise there is only one led light on, giving me a situation that is not covered in the error section of the manual.

Someone had that? Looks like the bottom left is the one that should be always on, no?
Video attached on what happens when connecting the panel.
I tested the cables including the 30 amp fuse on a power station. That works fine, so the error is in the Ctek setup / connection of the 120 and 250 somehow?!
Thanks for any support to find the gremlin.
