Cerbo GX Watt usage from battery, DC and AC loads not correctly displayed?

Hi there,

I recognized a potential error. For this I want to explain it.

I am having a 24V battery system. At the moment with 2.3A usage at a voltage of 24.9V. The Quattro II displays a battery usage of 1.9A and an 230V output power of 17W. The DC loads are displayed as 0.4A, meaning 10W.

So the system subtracts the 2.3A minus 1.9A from the Quattro and therefore gets to 0.4A for the DC usage. And it just displays the 17W of the 230V usage. But 1.9A multiplied by 24.9V is a usage of 47,3W which the Quattro uses completely. So 30W are missed to be displayed. I would say this should be needed as DC load as the Quattro takes that from the battery and is therefore also a DC consumer. And so the 17W from the AC loads plus the current 10W form the DC loads plus the 30W which are missed are getting to. The 57W which are behind the 2.3A usage of the battery.

And all would be clear and understandable.

With the current way of displaying it is a little bit confusing as this additional 30W for the Quattro are displayed nowhere.

Thank you.
