RV charging schema

Hi,

I'm trying to improve my system (on my RV) wich currently has 2 separated electrical schemas with 2 separated batteries:

1) AGM (original) for most of the RV appliances.

2) LiFEPO4 for heating system, UDB charges, inverter and other few things, this battery can be removed easily thanks to andersen connectors.

I'd like to improve it by adding solar pannels to charge both the LIFEPO4 and AGM battery (see the schema below, i did not reported the fuses) note that the orion is used to charge the AGM battery not the lifepo4 the questions are:

1) can the blue smart charger be connected in parallel with the smart solar mppt ?

2) in case the lifepo4 is not connected, the schema will be able to charge the agm battery (with a limited current of around 5 Amps) with either the solar or the blue smart charger ?

Any other idea on how to achieve the same result?

The schema:

Thanks

1) Yes, you can connect them in parallel. Check, that the parameters are matching. Otherwise one will stop charging earlier then the other.

2) Don't know exactly the behaviour of the OrionXS when not connected to a battery, but I would assume that this should work if you limit the input current of the Orion to the max of the Blue smart charger. The blue smart charger should be able to manage this, as it is also able to serve as a power supply without any battery, but then the voltage is reduced to 12,xV as far as I remember...
