I started to use Modbus to read some data from EM24 and am little bit confused about the numbers. Maybe someone can help me to interpret them.

When looking at the display of EM24 or alternatively on CCGX a see an "AC total" of 3775.8 kWh. In which modbus register can I find this value ?

I'm asking because when I read the modbus registers 2622 through 2626 ('Energy from net' for L1,L2,L3) I get a total of 6832 kWh. The total of 'Energy to net' is 6646 kWh
