continues to occur, please contact the
supplier.
AL11
Insulation resistance
error
Converter DC input
insulation resistance too
low and fails to meet
specifications
1. Disconnect the solar panel array from the
converter, and disconnect the converter
from the grid.
2. Confirm that the converter DC input
terminal and the solar panel array are
normal (e.g., no short circuits, no
damaged wire insulation).
3. Re-connect the solar panel array and the
AC grid to the converter. If the error
continues to occur, please contact the
supplier.
AL25
Overtemperature
warning
Converter overtemperature
so derating mechanism is
triggered
1. Lower the ambient temperature of the
converter or relocate the converter to a
well-vented location.
2. If the error continues to occur, please
contact the supplier.
