Converter Question??

grashley · Dec 16, 2017

I finally dug deep enough to get a model number off my converter. It is a WFCO Model 9875 converter. 75Amp DC. 3 stage charging at 14.4VDC, 13.6VDC and 13.2 VDC. By what I remember, this is a decent converter even if I leave the RV plugged in all winter. It connects through a WFCO 8930-50 panel.

Am I in good shape or do I need to budget for a different converter?

should be. WFCO Does not have the best rating for long life but the most common failure mode is safe.
(Failure to enter bulk mode).

Should be fine. I have the 9855 which is essentially the same but lower amperage and was thinking of swapping it out for a Progressive Dynamics unit but after I read the specs I will wait until this one craps out. Little to be gained although the PD units do some pulsing in float mode which is said to prevent sulfating. Not a big deal unless you have AGMs but at $85 each for 6 volt FLAs I would be waiting a few years to see a return on the investment.

IF you are worried, just disconnect the battery terminals and set a Battery Tender on it, and forget about it.

It will monitor the battery until it gets down to around 12.3ish volts, then it turns on and brings it back up to about 14.1ish and then it turns off and just monitors the battery.

I have one connected to every battery on our place.
motorcycle, Lawn tractor, RV, Suburban ( don't get used a lot )

the car don't have one, but it gets started almost everyday.
