Looking at the DC power, it does not match the voltage/current reading.

51,74 x 195 = 10089

Any idea?

The inverter is not 100% efficient, at this load level, probably around 90-92% and where I imagine the discrepancy is coming from.

That and the ve bus doesn’t actually measure current.

Voltage is measured so the power (which is also derived from power factor) and actually is more of a calculation base on ac load.
