For the converter to work properly it is important that the 12v output wire is heavy enough to handle the flow to the batteries. The instructions should give what is required. I use the heaviest wire, usually 4ga, I can get in the converter wire sockets. I run them direct to the battery bank.

I replaced my 7445 with a IOTA 55, I have a 6 AWG wire so that is key. SO far everything seems to work but I have yet to really test it out, plus I have a 400 Watts Solar system.

As Jauguston said. The wire from your converter to the battery will be the limiting factor. I went from a 45 amp to a PD 4655 and it worked ok but to get as many amps into the battery as quickly as possible I also went from 6 g to 4 gauge cable. If you are doing normal charging and not doing all your charging with a generator you will be fine with 6 g. There is not a problem using a gen and 6 gauge, it's just that as I build I want to minimize gen run time so I want to minimize voltage drop. Ideally the converter would be mounted next to the batteries to keep the voltage drop low but it's not practical. Three things about voltage drop- length of conductor, size of conductor and to a lesser degree temperature of the conductor.
