I started a discussion here regarding an odd discrepancy between my batrium shunt and charging on the growatt 12000T DVM: https://diysolarforum.com/threads/odd-inefficiencies-in-growatt-12000t-dvm-unit-vs-batrium.29954/
I thought I would ask here to as I'm now into the troubleshoot phase. It's clear that the Inverter can only seem to output a maximum of about 40A to charge the battery from the utility. Once I start ramping up the utility current (Setting 11) the unit draws more power but the shunt on batrium still only shows 40A. The unit is allegedly capable of pushing out 100A from the utility to charge. Interestingly when I hit 70A in the setting there was a click and all utility charging stopped but no Fault alarm.
Worried this is a faulty unit.... sigh... Any thoughts on if I'm just doing something dumb? Note I set the max charging current (setting 2 to 140A although I don't have any solar in there at the moment) and played around with the bulk charging voltage (but we are well inside the c.c. range). No comms between BMS and inverter (I wish!)
