Grid failure:
The Sunny Boy displays a grid failure if the grid frequency,
grid voltage or the rate of change of the grid frequency are
out of the tolerable range.
Grid impedance too high:
The Sunny Boy has detected a failure based on non-per-
missible grid impedance values measured by the MSD.
Input voltage too high:
The Sunny Boy 1100E displays this blinking code if the PV
input voltage is above 400 V. Disconnect the grid and then
the PV-panels from the Sunny Boy immediately to prevent
damage!
Device failure:
The Sunny Boy is in a condition that makes it impossible to
return to normal operation. It has to be
