About Photovoltaic Energy StorageIf we use a capacitor that has a decoupling capacitor, so shunted to ground, then why for a DC source do we say the capacitor acts like a short at startup (t=0) thus having a high inrush but according to the top paragraph a DC source has a 0 Hz frequency so it has a very high impedance. This clearly is a contradiction.
