Hello,
i changed my system from 3 pcs. Victron Multiplus II 5000 (tree phase configuration) to 6pcs. new Victron Multiplus II 5000 (tree phase with on each phase two MP2 in parallel).
Before that change my VRM shows everything correctly.
But now my Consumption (daily "kWh") and also the Chart of the Consumption is not correct.
The Consumption (now "W") is correct.
What i discovered is following:
As long the batteries are empty or under the "minimum SOC (unless grid fails)" and there is no PV input - the consumption is shown right.
When there is PV Input, the PV Power is calculated as Consumption.
When the batterys are full or higher than the "minimum SOC (unless grid fails)" and there is no PV input - the consumption is nearly zerro.
In that chart you can see, till 05:00 we are pull power from the batteries but the chart shows nearly zero.
From 05:00 till around 08:00 we are under the "minimum SOC (unless grid fails)" (in my case 15%), and we see now the correct consumption (arround 2 - 4kWh / h).
From 08:00 till 17:00 we have PV input and you can see the cart is wrong again - the consumption cart is following the PV input.
And after 17:00 you can see the whole game again.
My diagram looks right - so that is not the problem.
Info:
For grid meter i use the new VM-3P75CT with the newest Firmware - V1.05
The MP2´s are on the Firmware V508
Cervo GX are on Firmware V3.20~37
So what is the problem?
As i know the consumption is calculated online in the VRM and not on the Cerbo GX or?
