EG4 › AC output / EPS inverter stage
Inverter backfeeds grid despite export being disabled
reported more than once
Symptoms
- A 12000XP wired only through its grid inputs for backup (never meant to export) is flagged by the utility for detecting power flowing back onto the grid, despite EG4's documentation stating the inverters cannot export power
- Separately, an early report describes an 18kPV feeding back a very small amount of power even with sellback disabled in settings
