I have a Magnum ME2012 Inverter with the ME-MR remote control in our coach that has me a little confused. I have read the manual enough now that the pring is getting blurry :-)
In the previous coach I could monitor amps on the remote to make sure I didn't turn on too many electrical items and trip the gen when dry camping by getting over the 50 amps. The remote is showing amps but they are illustrated in negative or positive figures and at levels that appear to be relative to battery level and not electrical consumption since they can be - 198A or + 100 amps depending on whether the gen is running or not. Any idea what my remote is illustrating/reporting?
I assume the inverter is set up at the factory for proper battery amp hour set points for the battery capacity installed in each unit. That said, my inverter BAT AHRS is set at 400 AH. The unit has four 6V Interstate batteries that show they are 232 Ah each. Seems like I should be using the 800 AH Bat AHRS option but unsure of that one at this point.
Curious if this topic is one that has been addressed and I simply overlooked it in the archives.

Your suspicion is correct, the amps you are reading are the DC amps the inverter is using from or charging to the battery, depending on whether it is inverting or charging. A rule of thumb I use is it's about 10x the inverters AC load current when inverting. It seems the Magnum remotes can only display AC load current if you have certain models, the ME-RC manual I looked at said: (MS-PAE, MS-PE and MSH Series models only).

I believe these numbers are instantaneous battery draw. Negative means going out, positive when inverter is charging the battery. You only get cumulative amp-hours in or out if you have the optional BMK module installed. I currently don't have either, so I get displays similar to yours. Not all that useful. I plan on installing the BMK module next spring.
