I got a 3ph setup with MP2 3000, two PV inverters and a DC solar charger Smartsolar 150/100.
The numbers in the advanced tab a correct.
But the number for Solar Production seems to only add the production of the inverters, but not of the solar charger.
Is there a way to configure this for "Solar Production" representing all inverters and chargers?
The 44kWh in the screenshot is what the inverter produced. 
I downloaded the raw data forr the inverter and the charger and did the maths in Excel:
The colums fot the inverter sum up to round 44kWh, the numbers for ther charger to 19.2kWh and this is missing. But the charger is in the system, see following screenshot:
