system is a victron multiplus II 12v/3000 with a 4s 280a eve diy battery.
I figured I might as well use the the feature since it is offered. what issues can having it enabled cause?
do I need a victron shunt to use this feature or is the monitoring device built into the inverter already?
yes I also charge with a victron mppt 30 amp cc no- communication to inverter.
no plans for a cerbo or gx device.
what I do also like about the battery monitor feature is it allows a low soc inverter shut down . when selected in the programing page one must fill in a soc bulk finished percentage to use any of the features I belive.
What about the VE blutetooth dongle and VEsmart network?
Wouldn’t that have the MP talking to the smart shunt for SoC?
Or is the MP only able to see that via Cerbo?
So smart shunt + smart MPPT + smart dongle all on the same VEsmart network won’t share SoC to the MPPT?
I mean the shunt rules all for what goes in and out of the battery and the MPPT bases its charging off the smart shunt voltage/SOC settings.
I thought the smart dongle does have a voltage input into smart network (just like temp) as it has a voltage sense lead just like the shunt, I think the shunt voltage is just considered the master.Sorry. the OP doesn't have a smart shunt, and I missed that detail in your post.
The smart dongle will have no voltage input into the VE.Smart network due to the presence of the smarshunt, but may provide temperature data if the smartshunt doesn't have a temp sensor.
The MPPT in no way uses SoC in it's charging. It will use the shunt provided voltage and battery current value to establish absorption voltage and tail current if so configured. It will use any available temp data for lead acid temp comp or LFP low temp protection.
