Five Of These In Series?
Adjacent to large inverter terminals for short burst microwave or other load duty? Or do they need current limiting control. Just wondering...

Other than cost there are more problems with these caps.
They have a high leakage current. They won't hold a long term charge.
The caps may have a 20% tolerance. One cap in a string could have a capacitance 20% low. As a result of lower capacitance, this cap will have 20% higher voltage. It can now over voltage and explode. The fix is to add a parallel resistor to each cap. These resistors will also discharge the cap bank.
So you got leakage current and the resistor ladder that discharge the cap bank.
