martin-nolte asked Jun 15, '22

Hello,

why is there every time a 10% differenz between the PV Power (845W) and the Load Power (771W)? Is it normal or lost I 10% Power?

Thanks

Martin

All devices consume some power/energy.
There is an energy loss when converting from DC to AC (inverter efficiency is not 100%).
Losses in the wires.

This is the most commonly asked question here, easily searched for.

There is loss in DC/AC (and AC/DC) conversion, this is anywhere from 10-20% - cabling, heat, etc etc

Completely normal.

With a big Load it now 300W differenz between the PW Power and the PV Load. Is it normal?
