[RE-wrenches] Converter from 230VAC to 12VDC

[Kent]

The Midnite Classic charge controller can be used with hydro systems. 
The existing 230VAC would have to be stepped down with a transformer and 
rectified ahead of the Classic. The transformer(s) should be selected so 
that even at open circuit, the rectified voltage doesn't come anywhere 
close to the Classic's voltage rating. Considering that it is only 500 
watts the transformers shouldn't be very expensive.
