Hi Kirk,

If you use a 200vdc midnight CC you'll have no issues.
When you rectify 120vac its up around 166vdc
( uses the peak vac which is around 170vac.)

For a 150vdc max controller ( midnite 150)  or a 144vdc ( outback FM) then a buck transformer or standard transformer is the trick to reduce the AC and hence the DC for these lower voltage units.
