MMC setup opinions


I wanted to post my intended MMC setup to see what the list thinks.

I am using Panasonic ECWH(V) 1.6kV .056uF caps.(purchased from Terry) my
planned max input is 12kV rms which gives me a peak voltage of
16,970.4V(12,000 x 1.4142 = 16,970.4??) so I am planning on using 12
caps/string which gives me a voltage rating of 19.2kV.This should be o.k.
right? Now what I realy need confirmed is the capacitance of each string.
Here is how I figured it...(1/.056=17.857 x 12 = 214.5) 1/214.5 =.00466uF
Is this correct? now if I am going to use five strings and assuming the
above is correct that should give me a todal capacitance would be around
.0233uF right?

well thats all,thanks for any help
