EPEVER 100 AMP, why would my CC output more when battery voltage is increased by an alternate charging source?

To clarify, winter doldrums are knocking down harvest. Ill get exact numbers tommorrow, but my EPEVER will be charging at say 4.5 AMPS @ 12 volts (pitiful), battery voltage will be like 12.4.

I'll fire up the generator which then powers an a/c charger which then makes the battery voltage come up to like 14.3-14.4 volts.

The charge amps on the Epever will then jump up to like lets say 18 amps.

Is this a flaw in this charger? Anyone ever seen anything like that before?

That is strange.
So if you use clamp-on DC Amp meter on the charging output wire of the Ep, does it also show 18A?
What does it show at night without solar?

Haven't gotten that far yet. I am monitoring the system remotely from a couple hundred miles away.
