MPPT Solar controller setup issue

Ive replaced an old solar controller with a Victron Energy SmartSolar MPPT 100V 30 amp 12/24-Volt Solar Charge Controller. The previous setup also charged my cab battery as the solar output ran through the motorhomes control unit. Should this still be the case, as it doesnt seem to be charging after the leisure batteries are charged ?

Thanks

It should be, as long as the settings and wiring are correct and the batteries are same type/voltage.

Please post screen shots of the solar parameter setup and the current/voltage readings. Battery details would help as well

HI All the batteries are 12v lead acid sealed type and the solar output from the controller goes through the motorhomes control unit, as it did before. I will get a screen shot of how it is set up on the app


Thanks for your answer

Maybe check the connections/fuse to the cab battery as well.
