Can't get lithiums above 88% and around 69ah. On a shoreline they will easily go to 100%. What is happening?

Victron Lithiums not charging above 88%
Some more information about your system and the installed components are needed to help you.
Maybe add some screenshots too.
Check your float voltage on your solar charge controller, it could be set to low. Orherwise you might have similar issues to me where the solar charge controller has incorrect voltage reading on your battery and cuts charging early
Thanks for that. This is my first post so still learning the format.
More details :- 600amp hour batteries @12volt. Victron system throughout
MPPT Solar 100 / 50 with non inverting control wire to Cyrix Li Load relay.
This on my boat and when stationary only getting solar so could be an issue with the solar.
I believe that when connected to shorepower your multiplus charges the batteries and when youre disconnected from shorepower your MPPT charged the batteries. The set voltages for the chrge cycle are probably set lower in your MPPT than in your multiplus. This would account for the diffrent max chargelevels
Why did you connect the non-inverting cable to the cyrix-li-load? That is not what it is for.

I'll have a look at that doc. I was advised to fit the cable to protect the batteries from over charging.
Further to that I disconnected the solar and just ran with the engine and soon after reaching 88 % the SOC went up to 100 % so clearly the solar needs configuring correctly.
Greatly appreciating the help
Ok here are screen shots of the mppt.
