I don't disconnect my solar system when plugged into shore power. The solar and converter charging circuit hasn't been affected on my unit. The converter charger is connected to the batteries to charge them and my solar charge controller is connected to the batteries to charge them. If my Morningstar solar charge controller doesn't see a need to charge by solar then it doesn't send the charge to the batteries.
