Inverter upgrade

I currently have a Magnetek-Parallax Inverter (MOD 7345, 7300 Series) in our 5th wheel and want to upgrade. I have done extensive research on line and have found references to Progressive Dynamics PD4645, and the Parallax 8345. The upgrades I mentioned only show 9 slots for fuses on the fuse board. My 7345 has 11 slots of which 10 are used. (slot 7 is unused). http://www.bestconverter.com/8345-45-Amp-Power-Center_p_69.html#.VUUAWZOYSi8 I can find no information that tells me what modifications I need to make to go from a 11 slot fuse board to a 9 slot. Both the 4645 and 8345 are 9 slot. Emailed Best Converters with the question, she just recommended the 4645 of the two but never answered the question concerning the slot configurations of the two fuse boards. Now that I have you confused, any suggestions?

    You are talking "converter" not inverter.
    I would suggest checking wire size between the batteries and the converter. If large enough I would go with a 55 amp. 55 amp
    Wire should not be a problem if the converter is as shown in link.

    PD4645 on Best Converter web site

    As per the manual:

    The DC Section:
    The DC panel features 12 positions, rated for up to 20A, for accessories including two low-to-full current rated branches. These
    can be used for lower current devices such as smoke and CO detectors. Each branch has a red LED light that indicates which
    fuse has blown.

    Call RANDY at Best COnverters and see if the PD unit you want will fit in the bottom compartment of the PARALLEX... It may be you only need to pickup just the CONVERTER UNIT and keep your POWER DISTRIBUTION UNIT you already have.

    Just tell RANDY you do not want a WFCO WF SERIES CONVERTER

    This is also a good time to think about going with more batteries. The PD9260C is what we use here in our WFCO WF8900 SERIES Power Distribution unit...

    I replaced my Magnetek/Parallax converter with the PD9260. I did not replace the power panel. I also replaced the existing #8 wire from the converter to the battery with #4 wire. Battery now charges much faster.

    Thank you for your informative posts. I emailed Randy at "BestConverter". He recommended the Boondocker 60. As mentioned above I will check the Gauge Wire from the Battery to the converter. I would think 6 gauge would be correct. I sent an email back to Randy to see if my 7300 series breakers will fit in the Boondocker. He mentioned that the Boondocker is a prefect fit for the existing opening and there are 12 fuse slots. It was a little pricy at $215. Again, thank all of you for the information. I mentioned the different models that you brought to my attention to Randy.

    V/R, Mike
