Question:
Installed this product and happy with so far. I also installed solar and DCDC controller to charge batteries. I am unclear how this product reacts to these other charge devices. I wired in such a way that I can isolate the truck/solar from the system when connected to shore power. Is this necessary? What will happen if all three systems connected at one time? Thanks

The Progressive Dynamics 4100 Series RV Converter w/ Charge Wizard # PD4135K is going to act as the primary charging source for your trailer batteries. The Solar Controller # GP72RR will see the batteries are charged and not provide power unless they see the batteries need additional charging. This is good to have in the event the converter fails.
I do recommend disconnecting the BCDC Battery Charger # RED96FR which will help prevent the trucks battery from being drained. This is best to only have connected when the truck is running.
If all 3 are connected at the same time they will all attempt to maintain power to the battery which will end up using up more power than is required to operate the controllers themselves.
