The issue is the the spread between indoor condensing temp (pressure) the evap temp (which in my case is -20C). Randen has a GSHP so the temp difference will naturally be narrower at -20C outdoor and current will be lower for the same pot.
Even the AHRI couldn't figure out how to measure efficiency with inverter systems, for the longest time. I guess that means that my value of 6.5A/leg is kind of irrelevant as it is just a snapshot in time.
