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.

Interesting... I've never seen it start at anything other than 14.4 even when batteries are very well charged at well over 13 volts. I'll watch it further-so far a small sample size. Going on a full hookup tour soon.

I haven't touched the charge wizard.. Anyway thanks for the info....

Question about PD w/ wizard: Short time I've used it observed voltage output seems to be based on a time schedule only (not touching wizard). 14.4 volts for x number of hours, 13.6 for x number of hours, then 13.2 after that. Batteries can be floating along drawing less than an amp from solar at 14.4 volts, start converter and 14.4 volts for the usual x number of hours from converter (solar off)-then the rest of sequence. I'm perfectly fine with this for my purposes-no complaints. Is this typical observation for these converters?

Today I turned on my PD9260 and it started charging my fully charged battery at 13.6v, not 14.4v. The battery voltage between chargers read over 13v, surface charge.

AFAIK, the PD acts one way for the 14.4 on its own and a different way (the four hours?) if the 14.4 is triggered by the CW. See their site with the explanation.

The original WFCO 75 would require more than a "15a" circuit, so swapping to the PD9280 that needs a 20a circuit should be no change.

However, I see something on bestconverter that indicates the WFCO 75s have only recently gone to a 20a plug.

The PowerMax converters from their 75 amper on up have power-factor correction so they can be run on a 15a circuit, even the 100 amper

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.

Too bad Keystone didn't install my new WFCO in a location where the button was readily accessible. I am thinking of installing a hatch in the pass through bulkhead so I can get to it. I have already installed a Xantrex TC2 close to the batteries but that 100 amps could come in handy at times.

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?

With a Progressive Dynamics if you draw more than it can produce it will simply throttle (reduce voltage till it is only putting out the rated 80 amps or about (might be 78 or 82) No damage

Batteries will discharge as long as they can then you loose voltage.

Years ago there was a device (Suspect there still is) called a power line conditioner... It was EXPENSIVE.. We RVers can make one for less.. I will block diagram it

Power source (mains)----Converter---Battery---Pure Sine Inverter--OUT

Yup, tha's all it was

I have both a 9180 with wizard (Converter) Bunch of battery and Prosine 2.0 (True sine wave, 2000 watt) and have, on occasion, done that to provide proper power to the microwave/tv/computrs etc.

If the battery wants to draw 100A, the PD XX80 will simply limit the charging current to 80A until the battery is sufficiently charged to accept less current. The battery will not be discharged, only be charged at a slightly slower rate.
