Dana,
You must have quite a bit of PV to switch out to 2
FM100's. You didn't mention what is the size of your battery and its
chemistry, what's you C-rate? If you're charging a large Lead acid
battery and maybe it was discharged pretty deep and/or you have
substantial loads once
It doesn’t make any sense that the controllers would be processing 2800 watts
internally.
It would be so hot you couldn’t touch them. Think of a 1500 watt electric
heater and this would be 2X.
I would put my clamp on to confirm. But I suspect it’s going somewhere

If you are using a Mate 3, this mismatch could possibly be the cause of these

I have always wired the PV negative all the way to the charge controller. That
way, the battery negative of the charge controller that happens to go to a
shunt has a proper representation of the current flow. I guess you could put
that PV negative at the same side of the shunt as the batt
OK, you wise guys.
I am upgrading my home off grid system from two FM 80s to two FM 100s.
The FM 80s were able to share the negative wire so you didn’t have to pull a
second negative wire.
I wired the FM 100 typical of how my FM 80s were wired with a number four
battery negative assuming and yes,
