How Does a Converter Hold its Voltage?
A solar controller uses PWM but how does a typical RV converter do it? How much play is there up and down to hold it there? I have a 12v mystery draw I am chasing down, but in the middle of this, ...

Perhaps my question is: Once the two voltages are equal except for wiring loss, and there is no amps to the battery, just to the load, how far down would the battery voltage get before it started to get amps from the converter again?
During that time, would you see negative amps on the Trimetric, even though the battery voltage is still as set (to one decimal place) ?
Your senerio should never happen, because the battery acts like just another resistive load to the charger/converter.....UNTIL the total load gets so high that the converter alone can't supply enough current and the battery helps out and is no longer charging.
The charger itself should NEVER actually experience "negative amps" because that would mean current going INTO the charger instead of out of it.
Are you sure that the control panel is not trying to show that a little power is coming OUT of the battery ? That might happen if it is designed to cut the charging completely when a certain charge voltage is reached.....instead of shifting down to "float".
