Real Power Production using solar
In this picture, the pink sinewave represents your actual 120V voltage as per your powqer outlet and the blue sinewave the current injected by the inverter. Both of them are synchronized, the current flow following the voltage, This is what we call real power. The source of this power is the solar panels.
Reactive power (3.4 kVA) with current injected at 90 degres
In this picture, the pink sinewave represents your actual 124V rms voltage as per your electrical panel and the blue sinewave the current injected by the inverter. In this case the current output is shifted from 90 degres. This is what we call rectivel power, here at 3.4 kVA. Since it is not aligned on the voltage, it requires no power from solar. But it can help boosting the voltage locally as a grid services.
