WFCO

Seriously?

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".

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.

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)

Don't spend money on a WFCO.

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.

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.

Here ya go, GordonThree :)

Post a too detailed answer and get silence in response: application loading...loading...loading...- "Sorry, your computer doesn't meet minimum requirements to run the app".

Open the door on the WFCO and remove the 2 screws and cover. Now remove the mounting screws and pull the unit out.
For charging off a generator I added a deck mount IOTA to replace the WFCO. The WFCO is still there, but I put it on its own breaker and switch it off when using the IOTA.

Strip the Whiffy buck naked and use it as a fixed voltage bench power supply and it is a happy camper.

Whatever it is, chill it out and it will not commit Seppuku as quickly.

Bad bad bad bad (is that enough bad's?)

Design for cooling. One pass over with a pyrometer and derate calculation for various components would send shivers up the spine of Boris Karloff.

The manufacturers are so cheap/stupid they won't spend the money to black anodize heat sinks. Silver thermal paste? Hahahahahahahahahahahahahahahahaha.

I don't fit the ideal profile as a gullible customer. Wotta shame.

You donna like da WFCO? Send them to me. They first go to nudist camp then on to the bench with an extra fan.

GOLDEN RULE no matter what the item, the cheapest available gets bolted to new high production RV's. If Bangenwhapper LLC introduced a converter that cost 7 bucks less than a Whiffie, Guess who goes Chapter 13 on an express to hell, bus?

SILVER RULE. Unless you ask an OP for an intended usage of an item that is not decorative you are guessing. WAG indeed.
