Shelly 3EM 3-phases Energy sensor - Configuration - Home Assistant

Try to reset your counters for energy and energy returned. Most likely is the energy that was counted before you fixed the wiring on the shelly (when you had readings of negative power the returned energy counter increased). Don’t know which loads you have but seems unlikely that you returned > 100 kWh in a day.
