I was wondering about the distance too. Mine is under the bed which is quite a distance from the battery bank
What does the TriMetric say for Voltage and that low current. When the converter is running the voltage that the Tri displays is the converter output voltage. If it is something like 13.5 then that is all the current that voltage can drive into the bank, which is why it takes so long to get back to 100% SOC. As others have said, if you discharge the bank somewhat, the converter should jump to 13.75 or 14 at the batteries.
Maybe take the SOC down to 75% and try it. Since this is your first run, the SOC will probably be 99% since it has nothing else to go on. You have a conservative 200 AH in your batteries and that I think is the Trimetric default setting.
Now that you know what is actually happening, your battery odyssey starts now.
