I have the wfco 75 amp converter and I think it is going out on me. I was checking on the inteli-power 9200 for a replacement. Do you think it would be a better replacement or should I keep what I have? Thank you for your input.

Slam dunk, hands down, 9280 all the way :B

I'd switch even if the WFCO were not acting up. Just search WFCO on this forum and you'll see why. About 1 in 10 WFCO's work as advertised.

I know a guy who has the 100 watt Wfco in his toy hauler. He has never seen 14 volts charging, even on very low batteries. Even tho he had dead batteries all the time, I never did convince him that it wasn't working properly, and that it was a very slow charger. But he did add 240 watts of solar this year, to make up for the POS Wfco's dead batteries all the time.All I know about the PD converters, is that whatever they do, they do it right !!! They make batteries last forever, and hardly need water once a year.

I tried real hard to get my 45AMP WFCO to go into boost charge mode. Changed out to large battery cables moved the WFCO within 6-inches of the batteries and all I could ever was maybe 30 seconds of 14.4VDC BOOST charge.I suspected I was not dropping my battery charge state low enough to have the WFCO product to kick-in. After a few more low batteries I give up and changed out my WFCO WF8945 converter/charger for a PD9260C. This was back in 2009 and have never had a battery problems since then. I never could figure out the "why" as almost all of the trailer units come out with the WFCO products... There are also some folks that swear by the WFCO Converter products as well. As stated above there are many many others who get rid of them as soon as they can including myself. Go Figure....I am still using the WFCO WF8900 series power distribution center with the somewhat brand new WF8945 Converter/charger unit in it. My PD9260C replacement converter/charger is used stand alone just five feet away from my battery banks... I can use either converter/charger by just throwing the proper 120VAC circuit breaker on. This gives me a backup converter/charger setup if needed. I however have never used the WF8945 45AMP Converter/charger since then... Roy Ken

Thank you all for your input. I'll be going to Amazon and ordering the 9280. I believe I'll get a voltage readout display also, just to keep a eye on things.

My rig has a WFCO 68100 converter - 100amps. PD maxes out at 80amps.

If I put in an 80amp converter, I assume that in the rare case that I'm drawing 100amps the converter won't keep up and the batteries will discharge.

Would that damage anything? Like will the converter "blow a gasket" or something?

New one to me - I was not aware WFCO ever made a 9200 series converter
PD does has such a series

I have a few 8875 WFCO units that are wonderful both with the RCMS remote control enabling manual control of the output voltage. With LiFePo4 batteries acturate and fully controlled voltage becomes more of an issue.

Sorry for the incorrect number, I was looking at the 9280. Already got the 9280 ordered and on the way.:) Probley be next week before i get it. Gotta change out the plug from a 15 amp to a 20 amp plug anyway. Already have the 20 amp breaker.

Anyhoo thank you for the amplification. I think your comment clarifies what I may have added confusion to. A 2-watt fan does wonders for an open frame 9255.

When removed from their housing and a fan is blown onto their guts, the WFCO seems to enjoy a longer lifespan. Not practical for an RV, but great as a power supply. The WhiffCo is right from scratch a poorly laid-out circuit.

Mex I have to disagree with your statement - there are several different models / series of WFCO converters - some yes have the large bleeder resisters close to other components that are heat sensitive however other models are as good or in many cases a better design than many of the so called "Made in the USA" converters that use the very same low cost overseas supplied components.

I too collect used / defective converters, inverters and chargers and will happily pay shipping charges to get them here to tinker with. Seen dozens of the PD's and Iota's blown up even the Paramode's none of them are failure proof.

WFCo has a reputation for low quality and short time between failures

Progressive Dynamics is the other end of the world (US MADE, Top Quality, with a rep for outlasting the RV in many cases.. Though there are some that one might argue are as good..NONE BETTER period.

NOTE if that WFCO is an integrated Power Panel/Converter (Fuses and breakers) a PDI 4600 Series.. Same as the 9200 but w/o the case.. May well replace just the electronics part without replacing the whole shebang.

Installed a PD9260 about 8 months ago. Love it!

FWIW, I left my WFCO8955 installed. Simply paralleled the PD9260 3 ft. from my batteries. Use the WFCO8955 as backup. If/when I sell my current TT I can remove the PD9260 in less than 5 min. Charge current with batteries discharged to ~12.2v went from 18a with the WFCO8955 to 55-58a with the PD9260!

Easy decision - go with the PDI.

Did he push the button?

Manual Bulk Charging Switch
For AGM/Lead-Acid type of batteries, with a push of a button on the front
cover you can manually bring the converter to bulk charge mode.
