Why is my INVT iMars BG8KTR showing AC overfrequency?
- JJohn JamesSep 10, 2025
An AC overfrequency error with your INVT Inverter is due to high frequency from the public grid.

Why is my INVT iMars BG8KTR showing AC overfrequency?
An AC overfrequency error with your INVT Inverter is due to high frequency from the public grid.
Why is my INVT Inverter showing AC overvoltage?
AC overvoltage in your INVT Inverter is due to high voltage from the public grid.
Why is my INVT iMars BG8KTR showing AC undervoltage?
AC undervoltage in your INVT Inverter is caused by low voltage from the public grid.
What causes input overvoltage in INVT iMars BG8KTR Inverter?
Input overvoltage in your INVT Inverter is due to DC input overvoltage.
What does output short-circuit mean on my INVT iMars BG8KTR?
Output short-circuit on your INVT Inverter means there is a short-circuit at the output.
What causes input overcurrent in my INVT iMars BG8KTR?
Input overcurrent in your INVT Inverter is due to DC input overcurrent.
What does manual shutdown mean on my INVT iMars BG8KTR Inverter?
A manual shutdown on your INVT Inverter means the device was stopped by the operation panel or upper PC.
