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. jay peltz power On Dec 15, 2014, at 5:38 PM, Kirk Herander wrote: > This has been discussed on this list in years past.
