Energy injected into grid (E_Grid), is the active power or apparent power?

[JohnC18]

The units suggest that this is active power, but please can someone confirm whether this is the case?

Hi!

Yes E_Grid is an "active" energy/power.

You can find explanation about active, reactive and apparent energy on the page: https://www.pvsyst.com/help/project-design/grid-connected-system-definition/power-factor/index.html?h=power+facto#apparent-reactive-and-active-power-definition

The table at the end of the page give you the different definitions:

Upon defining a power factor through the menu "Energy Management / Power Factor", the two additional variables EReGrid and EApGrid become available in the detailed results and also appear in the loss diagram.
