VE.Bus charge power (System)

I was going through the CCGX-Modbus-TCP-register-list

VE.Bus charge power (System) is described as 'System value etc. AND: Positive: power flowing from the Multi to the dc system. Negative: the other way around.'

Do I simply understand this as:

Positive: Grid power or PV-inverter power (on Phase 1 AC out) flowing to charge the battery; and

Negative: Battery being discharged to support household loads, or grid feed-in?


If so, I have separate sensors that measure PV and Battery power, why are these values then significantly different than VE_Bus_charge_power?

@Shubham

It would seem to be the case...

Negative is discharge - Positive is charge. correlates with the System Overview Battery State.

what if the VE.Bus charge power is negative and the battery state is charging? 2nd last row of the data you have shared is exactly that.

Does it mean that its also feeding to the grid at the same time?
