About Smart Meter and Power Limit Function
Q: How to activate output power limit function?
A: The function can be realised as follows:
1. Make sure Smart Meter connection and communication is functioning.
2. Turn on export power limit function and set the max output power to grid on App.
Note: Even if output power limit is set to 0W, there might still be a deviation of a max of 100W
exporting to grid.
Q: Why is there still power exporting to grid after I set power limit as 0W?
A: Export limit can be 0W theoretically, but there can be a measurement deviation of around
50-100W.
Q: Can I use other brand meter to take over Smart Meter in LG system or change some
settings on Smart Meter?
A: Generally, no, because the communication protocol is integrated into inverter and Smart Meter,
other brand meters cannot communicate. Also any manual setting change could cause Meter
communication failure. An exception is when using an LG Energy Solution approved meter for
VPP operations.
Q: What is the maximum current allowed to go through CT on Smart Meter?
A: The max current for CT is 120A.
