Hi,
in my setup I have an Cerbo GX, a Smart Shunt and an MPPT. All connected via VE.Direct Cable. I would like to add an Multiplus 12/800 and connect it via VE.Bus to the Cerbo. Will the Multiplus get Information such as SOC and Temperature from the Smart Shunt via the Cerbo?
Best Kirsten
Hi @Kstyler
Yes, you can do that by invoking DVCC. You can select the source of the parameter, say V and SOC from the Smartshunt and maybe Temp from the Multi. That leaves a free port on the shunt for an aux or midpoint V. Some Multis come with an included T sensor.
I like to use the Current from the shunt to drop my mppt from Absorb to Float when appropriate.
It's difficult to diagnose remotely without more info.
Understand that there's no 'flag' to tell you where certain parameters are being passed from. That's only shown in the Cerbo selections. Eg. Current from shunt won't be shown in mppt logging, but you'll see it at work if you have the Tail amperage set in the mppt, and when this is satisfied the mppt will drop to Float.
Voltage you may never notice if your system is set up with ample wiring and have no kit that's 'biased'. But once set in DVCC it should show the same everywhere, only subject to reporting delays.
