GridFree MicroInverter LED Status Error

When problem is detected, the STATUS LED will display error in RED color

Internal Errors
1x Red - Primary Over Current, main circuit current is too big
2x Red - Internal Over Current
3x Red - Internal Over Voltage
4x Red - Internal Under Voltage
8x Red - Grid Synchronization is not OK
9x Red - Safety problem detected

Grid Errors or Grid is not stable
5x Red - The grid is not OK, may be voltage, frequency, or other thing of the grid are not OK. MicroInverter will try later to resume function.
6 x Red - Grid Over Frequency
7 x Red - Grid Under Frequency
10 x Red - Grid Over Voltage
11 x Red - Grid Under Voltage

Input Errors
13 x  Red - DC input voltage error. The DC input voltage is out of working range of the MicroInverter.

Temperature Errors
12 x Red - Heat Sink Over Heat – the inner temperature is too high
14 x  Red  - Internal temperature error
