There have been similar posts but not really answered my concerns. I have 2 x MPPT, BMV712 and Originally IP43 charger, these were all connected using VE.Smart Networking.
I have 2 x MPPTs as I use one for the integral Solar Panels and the second allows me to add additional portable solar panels when static for a period of time (e.g. a show). Using VE.Start Networking it allows the MPPTs to synchronously charge batteries from both.
I have a GX device fitted now and my understanding is that you can't use both VE.Smart Networking and GX devices, which is fine in principal, why would you, also now have Multiplus installed.
My question really is, with the VE.Smart Networking disabled and the GX device set for DVCC, I have noticed on more than one occasion a disparity between devices, one MPPT showing on GX console as being in absorption, the other being in float or the Multiplus being in storage/bulk/absorption.
My assumption, incorrectly is that all these devices will be synchronised and charge stages managed by the GX device, they should all be in one or other stages but in unison, charge rates managed based on SOC, temperature etc by the GX device. Especially all devices are actively charging which can often be a scenario
