Is this system ok for a basic setup

Hi Newbie here, just wanted to ask would the following be ok as a basic lithium set up?

The EcoFlow can’t be connected to the load output of the Victron MPPT; it shouldn’t be connected to the Victron MPPT at all, as the EcoFlow has its own MPPT built-in so you can connect panels straight to it in accordance with its user and installation manual which you should be able to pull directly from EcoFlow’s site.

The REDARC DC-DC should be connected to your start battery on the input, not the alternator - that may be what you’re planning, not sure if you just left out the start battery on the input for simplicity, but in case not: a battery-to-battery charger requires a battery on the input, so make sure the alternator runs to the start battery, and the input of the REDARC comes from the start battery! REDARC’s user and installation manuals are available directly from their site.

Thanks Justin, for your useful input. I take it this would be a better solution where, when the leisure battery is full, I manually switch in the Ecoflow. Also, when on AC I/P and the sun is shining does the Leisure battery get a charge from both Solar and hook up simultaneously.
