Expert Reply:
Hey Tom! Yes, the Progressive Dynamics 9300 Series RV Converter Charger # PD79RR can use 6 gauge wire. The maximum size for those connections is 4 AWG. If you had to use something even larger it is possible to adapt it if need be, but that won't be necessary for your setup.
Are you upgrading to lithium batteries or was it just time for the old converter to be replaced?
