I currently have a Multiplus and Smart Shunt hooked up, standard fission, to a Cerbo GX.
My batteries do not communicate, although they do have internal BMS's. The need to be handled like any other dumb battery, settings not withstanding.
For, non standard / unsupported, reasons I need to be able to control Charge current without limiting AC input. I am using the charge current control assistant, right now, which works well.
The above is set to disable the charger when I set 0 current and that results in a Passthru state leaving Assist enabled and ready... Which is great.
The analogue input associated with the CC assistant is currently physically connected to a voltage reference circuit, just a few diodes essentially, which in turn is driven by the Cerbo GX relays.
It works but is admittedly a messy solution. So...
Dose anyone know...
If enabling DVCC, which I should probably do anyway, will allow me to control charge current, with the Node Red node, and still have the Multi go into Passthrough, as opposed to Bulk/Float with 0 current?
Are there any red flags or DVCC setup, particularly when manipulating it that I should be aware of for my simple setup? Still reading the manual but so far all the complication seem to be around ESS and/or more complicated integrated stuff.
Will DVCC and the charge current assistant conflict with each other or is the current setpoint common? (Mainly asking so I know which order to do/test things)
lastly, if I haven't asked something I should have when considering this stuff.
Any and all comments welcome,
