I live on a boat where I have two halves of my electrical system: 48V and 24V.
A Quattro connects shore power (or generator) to the 48V side.
An MPPT acts as the 48V->24V charger (enabled manually) A second MPPT acts as Solar->Battery charger (manually connected and configured to either the 48V or 24V side based on current needs).
I have a single CCGX.
I had noticed some of these products were also connected via the VE.Smart Network, and that that setup was ill-advised due to the presence of a *GX unit.
One of my future changes will be to add a second MPPT to the Solar->Battery such that each is dedicated to the battery bank (one for 48V, one for 24V). I'll use a manual throw switch to direct the PV power to one MPPT or the other.
How do I ensure each of the chargers (3x MPPT and Quattro) all properly communicate? Would one CCGX for each voltage be sufficient? Should I make the CCGX just operate at one voltage (say 48V) and disconnect the 24V items from it, opting for the VE.Smart Network? Can I leave everything on a single CCGX?
Thanks!
[ Note: I currently have it all on a single CCGX.
I notice when I have the Quattro and MPPT both powering the 48V (when I'm motoring, I need all the power I can get to the electric motors, so the generator and MPPT are both pushing) that the Quattro/MPPT have different opinions of float/bulk -- I assume this is fine as one will take over the work of topping the battery.
