Power Converter

Sorry double post

A hardy Hello to a "neighbor" aka Montana RVer

As the other folks said your converter has been given a bad reputation here on RV.net. From what I have seen over the last several years it's mostly due to poor installations not the unit itself.

Just returned from over near you earlier this week at the Thompson Chain of Lakes - great fishing and wonderful boating - back home for the weekend to stay away from the crowds

Suggest you check the voltage directly at the house battery - this way you will know what line losses are occurring and what is needed to get it fixed up. My WFCO 75amp has a manual override that can easily force the output to 14.6 Volts - Do the measurements and if things are not working as you expect send me a PM. I have been doing this stuff for 40 +++ Years and enjoying helping out

smkettner, yes, I do charge from a Honda 2000i generator at times. When you say to check the voltage at the fuse panel do I simply remove the cover plate and check the voltage by placing the electrodes of the voltmeter on the main breaker terminals - or do I do this at the battery terminals?

Yes, I do leave the unit plugged in for extended periods. I'll check to voltage as you suggested - have not done so in the past so I can't answer your question at this time.

Do you ever charge from a generator? Verify voltage steadily rises to 14.4 volts at the fuse panel for superior charging and less generator time.

Do you leave the RV plugged in for extended periods? Check voltage at the battery actually drops to 13.2 after a week of minimal or no use.

WFCO converters require a low resistance connection to the battery to work properly. Close to all RV installations do not provide a good enough connection, and the converter never ever enters bulk mode. The battery size also needs to be matched to the converter. If the 65 amp converter is paired with a single battery it will likely never enter bulk mode. If you don't often use a generator to charge the battery this is likely an insignificant detail. Not going into bulk mode greatly lengthens charge times and if you use a generator for charging this could turn into an important detail. As a quick check, run your battery down to 50% or less, apply shore power, and measure the voltage at the battery. If it's under about 13.75 volts the converter didn't go into bulk mode and likely never will. Because of this behavior a lot of RVers replace the WFCO converter with another brand, more often than not, Progressive Dynamics.

Ain't broke why fix it........

It's a 3 stage converter/charger.......meaning it will bulk charge a low battery then back off on charge voltage to maintain the battery.

Use it...worry about replacement WHEN it doesn't work.

It's a good converter.
