He may be right.
The Trimetric does not really show "net amps" but only the amps in or out of the battery. If there is a load running while you charge, the load will get its amps from the charger as long as its voltage is higher than that of the battery. Same with solar charging.
So the amps out of the charger or controller can be higher than the amps into the battery, which is what the meter shows, so you need to disconnect all loads to be sure both amps should be the same.
In that case, my worry about one-way amps is wrong, does not apply.
