Does frequency shift regulation depend on the nominal inverter power?

Hello,

if a Primo generates 3kW at 50Hz and the regulation goes to 51,9Hz, what's the new power rate?
Is it 50% of 3kW or is it 50% of the nominal inverter power?

Or asked differently: is the regulation of an inverter with less nominal power more accurate than with a bigger unit even if there is the same solar power installed?

As this is a little bit specific probably @Guy Stewart (Victron Community Manager) can answer?

Thank you!

regards,

porcini

Hi Changing the Frequency does not change the output or input power ratings,

Only voltage and amps will change the output powers (and also power factor) and as these are not changed when the frequency changes from 50 to 51.9 etc there is no power output change

Hello Paul, that was not an electrotechnical question.

Then more info is need as the assistant setting of 51.9 will depend then on the setting that are set in the Grid tie unit. this is not controlled by victron Systems, the Grid tie unit responds to the frequency change, and its response is determined by its own firmware etc
