Explanation
5
Display of the actual heat sink temperature, in °C. The inverter
will limit grid feeding if the temperature exceeds 65°C. If the
device temperature exceeds 80°C it will switch off automatically.
6
Display of the various operating phases:
Normal grid-feeding operation. Power is fed into the grid.
Waiting for sufficient solar generator power. The generator
voltage is not sufficient for grid feeding, or the grid feeding
process was stopped and the system re-started after a failure.
Waiting for night shutdown. The generator capacity is no longer
sufficient for grid feeding, and the device waits for the night
shutdown.
7
Error-messages:
The grid frequency is over or under the allowable range.
This is a utility fault. It will clear itself when the frequency is within
the specified range.
The AC voltage is over or under the allowable range.
This is a utility fault. It will clear itself when the grid voltage comes
within the specified range.
The unit detected a critical operating point and shut down to
secure itself. This error can be caused by a utility fault DC or AC
power surges. It will clear itself after a few seconds.
The internal temperature of the unit is greater than 176°F (80°C).
This fault is caused by too high ambient temperature. It will clear
itself when the temperature has dropped below 176°F (80°C).
The unit detected a grid impedance step greater than the
allowable limit. This is a utility fault. It will clear itself after a few
seconds.
The inverter detected a current leakage to ground exceeding 1
Amp. Inspect the solar array for ground faults and repair any
damaged cables. Once the repair is made and the GFDI fuse is
changed, the fault will clear and the inverter will begin normal
operation.
An internal failure occurred. It will clear itself and the unit starts
again.
