I have two stacked 8kw Quattros feeding a 100A autotransformer which then feeds my panel. My system is monitored with a Cerbo GX. My Cerbo GX failed and I needed to replace it. After the replacement I noticed a difference in output in the AT between L1 and L2. I'm noticing a 10 amp difference between legs. This was not the case before the failure.
Is the difference between legs normal and it is just how my panel is balanced or is there a configuration issue that was missed on the Cerbo replacement - there seems to be no ability to control the AT from the Cerbo. Does the AT balance L1 and L2 evenly or is 10 amps difference permissible?
The issue persists through the Quattros as well - if I limit the grid current to 40 amps the Quattros will pull 46A on one leg and 37A on the other. It all feels related.
