Installation Guide
Description
Self-test 24-hour timeout.
Self-test must run at least once
per 24 hours.
Too many RCMU events
during the past 24 hours. Only
four automatic reconnect
attempts after event 34 is
allowed during a 24-hour
period. The inverter will
automatically try to reconnect
after a certain period.
Grid code settings invalid.
Gatedrive error.
Internal fan error. Maximum
output power has been
reduced.
Measure
None.
Wait up to 24 hours. If event 34
also occurs, follow the action for
event 34.
Restart the inverter. If event
persists, ask Service to generate a
new grid code file or reselect a
standard grid code.
Restart the inverter. If the event
persists, call the Service.
If the event repeats, call Service.
Measure
polarity is correct, call service.
Restart the inverter. If the event persists,
call the Service.
Replace PV overvoltage protection
device. See SPD replacement
instructions for details.
