This is a typical WFCO 8900 series Power Distribution Center alot of the time installed under the Fridge near the floor...
My unit was a 45AMP setup. When I installed a bigger Battery Bank I need a larger Converter/Charger unit so I got the Progressive Dynamics PD-9260C unit which is a 60AMP setup and it would have set inside the WFCO 8900 series cabinet (Bottom Compartment) but I decided to use the PD-9260C by itself closer to the battery bank. The PD 9260C unit is paralleled on the DC wiring going to the battery bank so I can have two unit units to use for a backup mode if needed. I just turn ON the one I want to us. It turns out the PD9260C is an excellent MULTI VOLTAGE Smart Mode unit so it gets used the most. I was one that could never get the WF8945 WFCO unit to ever go into SMART MODE charging. It always just puts out 13.6 VDC no matter what... My PD-9260C puts out the 14.4DC-13.6VDC-13.2VDC smart modes operation which almost automatically takes care of my batteries...
I understand you can now get the PD-9260C that put out the 14.8VDC boost charge mode that the dual 6VDC GC2 batteries like to see...
