Other Questions - Goodwe ET Series User Manual

Q: In the app, some columns show NA, like battery SOH, etc. Why does that happen?
A: NA means that the App has not received data from the inverter or server because of communication
problems, such as battery communications and the communications between the inverter and the app.
Smart Meter and Power Limit function
Q: How to activate the output power limit function?
A: For the ET system, this function can be activated by following these steps:
1. Make sure the Smart Meter connections and communications are functioning correctly.
2. Turn on the export power limit function and set the maximum output power to the grid on the APP.
Note: Even if the output power limit is set to 0W, there might still be a deviation of a maximum 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.
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.
