Battery Charging Troubleshooting

Here’s my equipment:
Battery Monitor with shunt. ( not a Victron or Trimetric but seems to be accurate)
Trojan T-105’s x 2 ( one month old, water level is good)
Progressive Dynamics 55 amp converter with charge wizard( I replaced a WFCO)
200 watts portable solar.
6 AWG cables from converter to battery via battery disconnect switch. Looks like about a 5-6 ft run.

I have a new Fifth Wheel. It appears that my batteries are not charging above 90% using the converter. Seems the charging amperage is minuscule above about 87% or so. On the converter a whole day goes up like .4 %. Today my monitor basically showed no charge from converter (less than 1 amo) I hooked up solar today and was getting about .5 Amps charging but was charging. I did not have a battery monitor on my previous fifth wheel but the voltage and behavior of the charge wizard indicated I was charging to 100% after a couple days. Is it possible something like the battery cutoff is retarding charging from the converter?
  • Thank you all for your help. You have given me some good ideas to alleviate my issue.

    I wouldn't trust the meter, the uber low current may suggest that the batteries might already be fully charged...The meter should be re-syncronized once the battery has been properly determined to be full...
