About Photovoltaic Energy StorageIn the same way that capacitors can act as high-pass filters, to pass high frequencies and block DC, they can act as low-pass filters, to pass DC signals and block AC. Instead of placing the capacitor in series with the component, the capacitor will be placed in parallel.

About Photovoltaic Energy StorageIn other words, capacitors play a role in low-pass filters, offering a low-impedance path for high-frequency signals to ground. In an RC low-pass filter (Figure 2), impedance decreases as frequency increases, so the ratio of V I to V O depends on the value of R, C and the signal frequency.

About Photovoltaic Energy StorageThe above circuit uses two first-order filters connected or cascaded together to form a second-order or two-pole high pass network. Then a first-order filter stage can be converted into a second-order type by simply using an additional RC network, the same as for the 2 nd-order low pass filter.-order low pass filter.
About Photovoltaic Energy StorageThe value of the capacitor will depend entirely on the range of cuttoff frequencies that you want to achieve. Also, I assume that you will be driving a speaker (8 ohm possibly) with this circuit. To maintain low power dissipation in the POT, the POT will need to be very low resistance, which will make your approach very impractical.
