They make a 32 amp version which would run most planes as a primary if you don't fly with the landing lights on all the time. I believe the intent is to provide a bracket to fit the front cover, since a new cover would be VERY expensive. The same unit would probably be fitable to the PSRU if you wanted to get creative. Barret Engineering (The Parent Co) could probably provide the flattest pulley or just a magnet holding cup to fit in the PSRU. You would have to provide all the dimensions though. Since it would be custom it would probably cost more.
