Hey Jay, yes you can wire the Progressive Dynamics 9300 converter part # PD89RR to a battery bank wired in parallel to charge them all. How many batteries are in your bank?

Hey, i might have phrased the question wrong. I was wanting to know if the chargers can be placeed in parallel? For example 2 of the 9300 80 amp to produce 160 amp charge current?

@Jay Yes that would work technically as you can have multiple 12 volt power sources connected and Progressive Dynamics has stated that their chargers can be used in parallel.
