Progressive PD9130 vs PD9245

Does the 9245 have a cooling fan or just a large heat sink?

If it is a 9130, it is a stand alone single stage converter, if it did not have the optional charge wizard plugged into it.
Yes, replace it w/ a 9245, which is also a stand alone converter. And to compliment it, add the plug in "charge pendant", so you will have manual control over the charge stages when needed.

The current PD9130 is a deck mount and has 2 wires that I will have to trace out to where they go they look like 6 gauge wire but cannot find a listing on the wire yet.

Unless you have 10 gauge wires going from the converter to the batteries and/or distribution panel, get the 9245.

If you have 10 gauge wires, still get the 9245 but also upgrade the wires to something appropriately large. 6 gauge might be reasonable.

Call Randy at BESTCONVERTERs or order just the PD9245 converter/charger unit from AMAZON... Not familar with what 120VAC and 12VDC Power Dist Panels comes with the PD9130. If it is just a couple of AC breakers and two or three 12VDC fuses you might want to consider getting a larger Power Distibution Panel setup with your converter/charger upgrade.

Mine is setup where I can have one full size main 120VAC beaker and 8 physical smaller half size slot breakers along with 11 each 12VDc Fuse positions. This may be the reason PD brought up the issue of staying with same as installed.

Your 120VAC/12VDC power Distribution Panel may be a stand alone thing and the converter/charger will be a deck mount version model.

If you want to add more batteries and want to re-charge then in a quick 3 hour time frame you will need to have a charger with the capacity of supplying 14.4VDC @ 17A-20A of DC Current Capacity for each battery in the battery bank. 45Amps for two batteries 90Amps for four batteries etc...

Depends on the wire size and fuses from the converter to the batteries. If large enough for the 45 amps, go with the PD9245.

PD9245. Ignore undersized PD9130 recommendation from OEM manufacturer. You won't have any problems.

I have not made the that upgrade, but I would not hesitate to do so, the Charge Wizard is worth it.
