Don't go too big with WFCO. If the rating is too high it could have a harder time with the automatic shift to boost/bulk mode. With one or two batteries I suggest 45 is plenty. Another great option IMO is the Xantrex 40 or 60 amp converter.

The converter rating is the maximum amount of DC amps the converter will output, nothing more. The automatic battery charge operation hasn't anything to do with that.

The charger will be running in the 10 amp range after just a few minutes. The difference between the battery and charger voltage determine the amp flow and the battery voltage builds fast on the plate surfaces.

The WFCO converter (the converter module) runs about $160 and in, indeed, a more economical solution.

Here is my story with the Parallax converter.

Got my new trailer around the middle of April. Had it in the driveway for a couple of weeks, plugged into the house. Went out in the camper one day and noticed that the lights were not working. Only thing working was the microwave. Checked the 30amp fuses, both blown. Replaced both fuses, and nothing.

I have the 7100 series Parallax converter. Anyway, dealer sent me another one, put that in. Everything worked. That was on a Friday, went camping Saturday night, everything working fine. Sunday morning, the 30amp fuses blown again. Replaced them, nothing.

A buddy of mine took my battery off and charged it off his camper, hooked it back onto mine and things started working again. Now its not charging my battery.

I'm confused. My dealer is not across the street from me and is some fooling around to get parts from him.

I don't want another one of these converters in my camper. What options do I have?

If you don't want another Parallax then tell them. I'd ask to send you a different make of convertor! Hopefully the physical characteristics will ensure a proper fit. I think I stated in my OP that the technician who came to the CG, said the circuit board was an "up-dated" and "improved" part from Parallax. See if you can find out if you indeed got the "new" part! Good luck. Keep us posted.

My trailer had a WFCO from the factory (piece of junk). It blew.

Went through a string of warranty replacements, some WFCO, some Parallax. (BOTH are piece of junk !!)

Finally bought a Progressive Dynamics converter with my OWN money and have finally stopped have to change converters on a monthly basis.

Since this is still a warranty item keep working on it from this angle.

What most folks call "the converter" is actually the power distribution center. Handles both AC and DC current. The actual converter is an electronic module that either fits inside, or is a separate box. The linked 55 amp WFCO mainboard should contain all the circuitry you need, but may not fit in your distribution box.

Our 55 amp WFCO "converter" uses forty (40) not thirty (30) amp fuses for battery protection. But these will still blow instantly if the battery is connected backwards. 12v DC trailer wiring uses White for ground and Black for positive.

You can see the converter inside our WFCO power center when I pull the cover:

As I noted a couple of days ago a complete WFCO 55 amp unit will run ya about $250 and just the converter abou $170.
