of 100 W when exporting to the grid.
Q: Why is there still power exporting to the grid after I have set the power limit to 0 W?
A: The export limit could theoretically be 0W but there will be a deviation of around 50–100 W for
the ET system.
Q: Can I use other meter brands to take over from the Smart Meter in the ET system or to
change settings in Smart Meter?
A: No, because the communication protocol is integrated into the inverter and Smart Meter,
other meter brands cannot communicate. Also, any change to the manual settings could cause a
meter communication failure.
Q: What is the maximum current allowed to pass through the CT on the Smart Meter?
A: The maximum current for the CT is 120A.
