The Phase Meter Correction application is dedicated to the 3-phase inverter IMEON 9. 12. It allows the inverter to automatically detect a phase inversion between the Smart-Meter wiring and the inverter wiring. More than that, the inverter will even correct itself the inversion and thus correct the excessive consumption that would result from the wiring error.
Without this application, in the case of a bad wiring, the inverter would be unable to make the injection by phase.
