Hello l have a cerbo gx + victron mppt + victron smartshunt. All connected to the cerbo.
On vrm I can read consumed ah. The value is increasing each day during the night. During the day the consomption is at 0 (because the sun is shinning and battery are charged so no current is going outside the battery).
Because of consumed ah stuck at 0ah during the day, I can’t know how many ah I get in my battery each day using vrm date. Is it normal ?
For instance here is a graph from vrm. There was not enough the 23/12 so the ah consumed don’t go at 0 during the day.
Is there a way to display for each day the consumed ah and the accumulated ah to check if I have more ah consumed or accumulated ?
I have the smartshunt data displayed in vrm but to be honest I have the feeling that it is a counter that is never reset it seems to count since the time I have connected it so it is not interesting:
What are the charge cycles ? What’s mean average discharge… where can I find the more wanted information like how many ah are in or out during a day, a week, a month ?
If the battery is fully charged then there is no power going to the battery.
This accumulates in the SOC. This is a percentage of the battery nominal Ah, so the input Ah can be calculated from the min and max Soc for the day.
This increments by 1 every time the consumed Ah equals the nominal capacity of the battery.
Thanks a lot for your answers. I have also a problem with the SOC being at 100% whereas my batteries are almost empty. I just answered another post a few minutes ago about it.
Do you thing that ‘false’ SOC could impact the charge of my accumulators during winter ? The victron mppt use the SOC of the smartshunt to load or not my accumulators ?
In serial connection the Ah is the same as that of a single battery.
Check the Full charge SOC reset conditions. You may need to raise the charged voltage or extend the time. If the battery voltage rises steeply as soon as charge is applied, then check the battery connections and battery condition.
