My Favorite All-in-One AC/DC Power Center

Progressive Dynamics makes great power converters. We sell their 9200 Series converters. As far as I know, they're the only converters that include a desulfation mode which spikes the voltage for 15 minutes every 21 hours while the trailer is in storage. This increased voltage mixes up the battery electrolyte and prevents battery stratification that leads to premature battery death.

Now, Progressive Dynamics has come out with the 4500 Series. The 4500 Series is the 9200 converter PLUS a 12-volt fuse box PLUS a 110-volt breaker panel all in one box. It makes wiring much easier AND it is less expensive than buying the components separately. We sell the 60-amp version and it is already becoming popular for trailers that are undergoing complete electrical rebuilds. I'll be installing one in my Caravanner.
