Meter CTs read zero or the wrong direction
reported in the field
Symptoms
- After installing CTs for busbar (power control system) management or an export/import meter, the inverter reads no current on the CTs
- Import and export are mirrored or do not move the right way when the inverters are toggled off and on
- The CT rating on the meter screen stays at 0. From the owner's side, a battery on manual charge settings charges itself from the grid and will not stop, sitting at 100% instead of following its configured cheap-rate schedule
