I also appreciate the Victron thinking in some aspects.
If you see in one of the previous messages, I’ve said “it’s better with CVL and also suits your hardware better”.
As per AIO, lets look at the schematic below.
Because of that high voltage bus of an AIO, the flexibility is maximum.
The HV DC bus is like a nexus, from where all things happens.
Just take a look at those grey arrows. All is bidirectional !!
Anyone can “help” (read PowerAssist) anyone on this topology.
If we take in consideration the initial OP message, imagine that when the SOC is 100, then the HV DC bus to battery DC/DC system can be disabled and then the inverter can take all the energy put on the HV DC bus by the MPPTs and use it to feed-in. All of it or only a part, according with the feed-in limit.
Not to mention that the battery is galvanically isolated from the high voltages of the PV panels and MPPT malfunctionings.
