What is the accuracy and consistency of power / energy measurements from the quattro?

How much can I believe the kW and kWh measurements from the Quattro? Is there a least count / linearity limitation?

e.g. if a 15kVA quattro measures 20kWh over 24h, would that be +/-5%? 10%? Unknown? Could it in reality be 40kWh? I'm asking because the power measured there would be less than 1kW, averaged over 24h. That's less than 10% of the rated power of the 15kVA Quattro, and energy errors tend to be cumulative.

Does this change with operating temperature? With stress on the inverter? With peaks and troughs / kW spikes of the load?

Any guidance here? Thanks

@Vaibhav Vaidya Worth consulting the documentation first, then searching and as a last resort post. ;) Looks like very much most, if not all your answers can be found here. https://www.victronenergy.com/upload/documents/Datasheet-Quattro-3kVA-15kVA-EN.pdf

Appreciate the direction, I haven't been able to find an answer though. What is the resolution and accuracy spec of the power measurement for example?
