Wfco 75amp converter or inteli-power 9200

[familyof3]

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.

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

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.

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.

Can you make out the goal posts from the nosebleed seats?

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.

I have about 700 watts lighting plus everything else.

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.

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.
