10.3.3 Error Mode
When inverter encounters an error, LCM screen enter error mode and an error
message will be displayed on LCM screen continuously.
AC VOLT HIGH
Vac 271V
This error message will remain on-screen until user presses the button on LED
panel to unlock and exit error mode. When exited, the LCM screen returns to
regular mode and goes to the information frame displaying the solar power
being generated at the moment (unit: W) and cumulative solar power that has
been generated today (unit: kWh). The error message mentioned above will be
recorded in Last ERROR information frame. Refer to the table below for
interpretation of all inverter error messages.
