We have a 1978 Red Dale with a B&W Industries 3220 Converter/Charger installed. One of our projects for the very near future is to install solar. I'm trying to work out how to do it alongside our existing converter/charger. The thing is, I can't find any info on the unit. Does anyone have line on an installation schematic, or other details on it? I can make an educated guess on how it is installed, but dealing with electrical and what not, I'd rather be sure than make a guess.
