If you have a higher voltage in storage, you wouldn’t need a capacitor bank as big as needed for a normal operating voltage. No charge controller needed as long as the open circuit voltage of the panels connected in series doesn’t exceed the designed capacitor bank voltage.. (A blocking diode would be needed)

In this case, the maximum storage voltage would be 90 volts and the unit would provide 12 volts @ 10 amps until the capacitor bank drained down to 50 volts.. (A 40 volt variance)
