Display- Wakeup Timeout
Description - Magnitude and phase voltage synchronization failed to be achieved within the time threshold.The grid-sync feedback via CAUX4 unable to sustain waveform for 30 sec.
Resolution:
1. Check for collapsing PV array voltage when inverter is entering power-export mode
2. Check Sync transformers TR5 TR6 TR7 in LC cabinet:
■ Fuses F78 -83 1-Amp
■ Resistors R7A-C | R8A-C | R9A-C wiring at TBT/R5 /R6 /R7
3. Check CAN Board CAUX4 connector J5 wiring to/from TBT/R5 /R6 /R7
