Does the Adria Twin Leisure Battery (with Solar) also top up the main van battery?

[APS_Adria]

Does anyone know if the Adria Twin (2022) with a solar panel fitted to the leisure battery, automatically top up the main van battery as well?

It does on our 2019 Twin

It also does on our Compact sc.
I first thought it wasn’t working as it only kicks in when the starter battery falls below 12.5v.

It depends on what is fitted. Only way to know for sure is to measure the voltage.

Multimeter - put across each battery - Over 13volts in sunlight = getting charged.

We are now on our second Adria Matrix, both originally from the same dealer (in Derbyshire) and in both instances is yes, the solar charges both the leisure and drive batteries. I suppose it will depend on how the particular dealer has installed your system.

If you can see the solar controller, you should be able to see a symbol of a chassis cab (represents the drive battery), and a symbol of a MH (represents the leisure battery). you should hopefully see a green light flickering between the 2 symbols, this will indicate both are receiving a charge from the solar panel. At least that's my understanding.

I'm happy to be corrected if the above is incorrect.

I don't know which solar regulator Adria fit to the Twin.
Our Adria Compact is fitted with a NDS SC300M MPPT regulator which is perhaps also fitted to the Twin.
There are two led lights on it. One for the engine battery and one for the habitation battery.
It is very easy to see which battery is being charged.

We Have a 2019 twin slb with a suncontrol solar controller fitted under the driver seat. If you look at the pictured attached if yours is the same the two red wires to the right are the outputs to the batteries. One to the leisure, second from the right and the other to the starter battery.
