4 T-105's = 460 amp hours times 0.3 = 138 amps max charge rate
or 46 amps at the Trojan recommended 10% c/20 charge rate.
So, Progressive Dynamics 9280 is, I think the largest 9200 made (am checking)
http://www.progressivedyn.com/power_converters.html had all the links you need, Best converters has the product for sale (Google them) if you have an existing power panel/converter combination change 92 to 46
The PD 92201 reomte pendent is optional
Or you can get the 9180 with the optional wizard.. Depending on when you buy that pair might be less expensive than the 9280/92201 combo, and electronically the difference is non-existent (the 9180 is the 9210 w/o built in wizard, the wizard plugs in, like the remote pendant, and provides the same functions as the remote as well)
When I got my motor home I did a lot of research on power converters.. I found a few common ones like the old Magneteks and most of the Parallex line where upgrades are recommended.. Upgrading from the 9200... NOT POSSIBLE, You can find some that for most of us are equal to a 9200, but you won't find one better.
The top converters
Progressive Dynamics 9200 with remote
Progressive dynamics 9180 with wizard/remote
4600 series with remote
All of these are the same electronically and functionally, different physically.
Iota with IQ-4
9200 w/o remote
(Again these two are, though not identical, so close as to make no difference)
All other 3-stage plus
All other 3-stage
All lesser converters
Magnetek 6300 (UPGRADE THIS ONE)
