Hello Carl,
If you just wanted to swap out the converter section of your Parallax 7300 you will need to check the model number to figure out what amps yours is and choose from one of the following:
If you have model # 7345 then it is 45 Amps so you will need the Progressive Dynamics Replacement Section for AC/DC Power Distribution Panel - 45 Amp # PD4645V.
If you have model # 7355 then it is 55 Amps so you will need the Progressive Dynamics Replacement Section for AC/DC Power Distribution Panel - 55 Amp # PD4655V.
If you are looking to swap out the entire unit, one of the following will work:
If you have model # 7345: Progressive Dynamics 4000 Series Mini RV Converter w/ Charge Wizard and AC/DC Distribution Panel # PD4045KA
If you have model # 7355: Progressive Dynamics 4000 Series RV Converter w/ Charge Wizard and AC/DC Distribution Panel - 60 Amp # PD4060K
Do you think that it is just a bad converter? It would be a whole lot easier to swap that out than the whole system. I attached some install videos that Kevin put together for you to check out.

Hey Carl, did you find out if the issue was just with the converter or did you decide to replace the whole unit? I'm curious to know what worked for you, as it could help others facing a similar situation.
