Happy Christmas to you all
I’m down on south coast of Spain atm and first time I’ve had a chance to test the solar part of my recent victron set up , the only thing is , the info makes little sense to me , please see attatched a current screen shot of what it’s doing and kindly offer some explanation of what you see , many thanks in advance

It’s bulk charging so you must have capacity in your leisure batteries, at 3.4 amps an hour which is not bad in winter. Seems to be working well.

The first section shows what is coming from the panels, your panels are wired in series which is why the voltage is so high at 56v and delivering 3.4 amps.

The 2nd section is what is coming out of the solar regulator and going into the batteries.
13.6v at 13.6 amps.

It's in bulk charge mode at the moment when the voltage reaches 14.4v it will change to absorption mode holding the voltage at 14 to 14.4v with a reduced current of around an amp. When the batteries are fully charged the voltage will drop to 13.6 to 13.8 at about 1 amp this is the float/maintenance charge.

Series connected panels is not the best for a motorhome as any shade on one panel you will lose all your output, it's worth considering changing them to parallel wired.

No it's not the batteries are charging at 13.6 amps you are reading the solar output.

How many panels do you have and what size are they?

As has already been said, the first section is the solar panel output, At 56.13V and 3.4A that makes it 56.13 x 3.4 = 190W.

The next section, as has been said, is what the solar controller is outputting to the batteries, 13.67V at 13.6, that makes it 13.67 x 13.6 = 186W. So the controller is losing 4W somewhere, which is about what I would expect.

The 'Bulk' state is the first of the 3-stage charging process (Bulk, Absorption,Float). The voltage should gradually rise from 13.67V to about 14.5V, stay in Absorption mode at 14.5V for a number of hours, then drop into Float mode at about 13.5V. If the sunshine lasts long enough, of course.

Only had a quick scan through the thread...

Your solar controller is outputting 13.6A. But, that is not necessarily all going into your batteries - you might be using some of it in the van.
