Step 1 Choose Micro-Inverter (Rated Power)

Pnom mic inv >= [PA stc]/2

Pnom mic inv Nominal power rating/Rated AC power of micro-inverter

PA stc Maximum power output of solar panel at standard test condition (STC)   

f2 Oversize factor. Typically, 1.05 to avoid power clipping

• f1 < 1.11 No power clipping

• f1 > 1.11 With power clipping
