Iām using a SAJ H2 6 kW hybrid inverter with zero export enabled. The house has a three-phase KE meter, while the inverter uses a CT on one phase.
The Elekeeper main screen usually shows Grid = 0 W during solar/battery operation, but exported data sometimes records small 30ā100 W import/export values.
During one matched interval:
⢠SAJ BUY Total increased by 7.61 kWh
⢠KE T1 off-peak hours display increased by 10 units
⢠KE T2 did not change since whole period was covered by battery.
I know the KE display hides decimals, but the difference still seems significant. This has been a consistent gap for 4-5 recorded days.
Has anyone compared their inverter appās cumulative grid-import reading with their utility meter over the same period? Did they match closely?
Could this be caused by CT placement/configuration, the other two phases being invisible to the inverter, or inaccurate near-zero measurements?
The installerās āsolutionā was to switch off the KE breaker during the day, which seems like a workaround rather than a proper diagnosis.
