Inverter capacitor can pass DC
CAPACITORS
Grid tie inverters require filter components in two key areas: The DC bus and AC output. The AC output filter is a low pass filter (LPF) that blocks high frequency PWM currents generated by the inverter.

Selecting dc-link capacitors for inverters
Of course, capacitors cannot pass dc current; thus, dc current only flows from the source to the inverter, bypassing the capacitor. Power factor correction (PFC) in the converter and/or
