WFCO

Thanks everyone ,except Gordon three. My son has WF-8955AN-11 on his toy hauler..This unit has the 110 and 12v and converter in one ball.Converter appears to be part of it all.Would have to look harder to disconnect the converter from the rest of it..Looks like first remove the cook top and oven and then go from there..Shouldn't be too difficult..All I have seen of it so far is pictures..looks like a mess in there.

As a group, WFCO converters have two major problems:

1) Unless they are close to the battery and connected with heavy cables, the mechanism they use to trigger boost mode rarely results in boost mode being entered. From the factory, very few (maybe none at all?) RVs use short heavy wires between the converter and battery, resulting in most WFCO converters rarely if ever going into boost mode.

2) They have a poor reliability record. Guessing from posts on the forum, they tend to have a 3-year lifetime. As with statistical things, there are some that go far longer.

PD converters have 3 major advantages:

1) The mechanism to trigger boost mode, while technically not as good as WFCO's, flat out works better in almost every RV.

2) Their reliability appears to be better.

3) They provide a way for the user to manually select the charging mode if desired.

The PD converters are weaker at supplying full rated current to the battery, but this is far overshadowed by the WFCO issues.

If RVs had good converter-to-battery wiring, and if WFCO converters were more reliable, they'd IMO be a better choice. With reality factored in, I consider PD to be the better choice.

Don't spend money on a WFCO.

They are good for Power Pole Princess RV's (always connected to umbilical)

Off grid they are as useful as a Diner's Club Card on the Pacific Crest Trail (utter wilderness)

In my opinion No. I have had both and strongly believe the Progressive is a far better unit. Both units advertised as being a multistage but I have only once seen the WFCO go into BULK mode.

You probably won't get anybody saying a WFCO is "a good choice" but I've been using WFCO for 14 years and they're "good enough for me".

Seriously?
