I have the Progressive Dynamics PD 4560 3 stag converter. I gave them a call and that converter is set up for both wet cell and AGM batteries, no adjustments necessary. My solar controller is Samlex scc-30AB, I called them and they said there are settings on the back of the display, I took out the display and there are 5 tiny switches, looking at the manual they were set for AGM batteries. The only difference is the AGM setting charges at a lower rate. There are no adjustments for the chassis alternator. Thanks all for your replies.
