The Smartshunt makes a great addition for accurate tracking of DC loads, reporting on V, A and W
What is missing is WH and Time Period. So there is no way to determine what is AC consumption vs DC consumption in a system, particularly with DC Solar Charging (MPPT)
Can you consider adding a WH function and reporting periods?
If you have a CerboGX.
Why not use your software of choice to get exactly what you want?
Just draw the relevant data from your CerboGX and format it and display it however you see fit?
Are you referring to the running V, A and W data output and viewable via the Victron Connect App under the Status → Output
Do you have a specific use case?
Why is it that the drawn Ah total does not meet your needs?
Just trying to understand why you think this is a feature (Wh / Time period reporting) that’s needed?
Hi @NFBR
Just trying to understand why Wh is important to your situation, as opposed to the total Ah consumed?
Total AH is since last reboot. No AH today, last week etc.
You can see the AH graph is greyed out
That said, WH is more accurate than AH, but either could do. Neither is available.
So the Consumed Ah is the consumption since the last syncronisation to 100%SoC. For exactly how that is determined see the manual.
The manual says:
Blockquote
Consumed Ah
The battery monitor keeps track of the Amp-hours removed from the battery compensated for the efficiency.
Example: If a current of 12A is drawn from a fully charged battery for a period of 3 hours, the readout will show -36.0Ah (-12 x 3 = -36).
Please note that if the “Consumed Ah” reading indicates three dashes: “—” this means that the battery monitor is in an unsynchronised state. This mainly occurs when the battery monitor has just been installed or after the battery monitor has been left unpowered and is powered up again. For more information, see the Synchronising the battery monitor chapter.
I don’t know why your Ah drawn is not selectable, mine is (I do use a Lynx shunt, but it is fundamentally the same software), along with period:
Is your SmartShunt configured as ‘Battery Monitor’ or ‘DC Meter’?
What is is you are trying to see via the Wh data or what is it you are trying to determine from it?
DC System
Batts have their own shunt.
This is to accurately measure DC loads vs AC loads.
OK so this is in the DC system cabling in a Batt → Busbar → DC system supply cable → DC system shunt → DC Loads, type layout?
And this would then give you the ability to see exactly what your DC system was consuming?
Batt - Batt BMV712 Shunt - Main Busbar - SmartShunt - Loads
The Smartshunt and VRM don’t account for daily DC use
