Annual yield calculation

[Maggie]

Hi,

Can you please tell me what power rating is used when calculating the annual yield of an inverter - is it the nominal (rated power) or the VA rated (apparent) power? 

Many thanks.

Dear Maggie,

Thank you for your inquiry.

If you specify a displacement power factor (cos φ < 1) in the options, the inverter's active power will be used instead of its apparent power.
