What is Wrong with the OEM Converter?
I’ve always suspected that the manufacturer installed power converter in our Keystone Cougar fifth wheel did a poor job when it came to charging our batteries. They never seemed to pack the punch I felt they were capable of. This suspicion was confirmed when I installed a Trimetric battery system monitor and could get an exact reading of the voltage and current supplied. The maximum charging voltage I ever see from the stock WFCO converter is 13.6 VDC but my large 6-volt golf cart style lead acid batteries need voltages as high as 14.4 – 14.8 to properly charge.
IMHO the original converter was never giving the batteries a complete charge and is terrible for boondocking, especially with a larger battery bank like I have. Now that I’ve installed 400 watts solar system with its own charge controller capable of reaching the proper charging voltages my battery bank is performing much better and I’m a happier dry camper.
