the pre-made cables normally come with one connector on . . (for the panel end)

enabling you to run through the vans bodywork.

then terminate the other end with either another MC4

or

a screw terminal into the solar controller. .

The panel I'm interested in has a circular rear entry, 4mm twin flexible cable. I am wondering if there's a reason I can't just crimp the extension cable running to the mmpt with normal flexible cable? There's not really a need to use solar connectors once the connections are done inside the van?

@eirej , yes you can use any cable inside, as long as it's the correct thicknes..

In this example 4mm or larger.
