Solar charge setup

Advice please.

Need some direction on how to setup a vehicle system for solar.

I already have EHU into victron inverter/charger which then can charge house battery.

I also have a split charge controller to allow the alternator to charge the house battery.

So house battery can be charged via EHU or Alternator at present.

Master battery also can be charged by EHU or Alternator.

I will have a dedicated battery charger for house battery as I will be going lithium so I will not be using the inverter/charger for battery maintenance.

Want to introduce solar into the mix.

How do I get the solar to provide power to house battery charger but also charge master battery. I have seen talk of trickle charge power on a second line but they don't seem common.

I know some controllers can have 2 outputs but then how do I stop too much power being delivered to the master battery with a second controller.

Thanks in advance.

I assume master battery is the starter battery.

Use an Orion DC:DC unit, output to starter battery. You may have to adjust the 'engine detect' to pick up charge voltage from solar.
