Display - Grid Overcurrent
Description- Software detected grid over current Trips if any phase > 3090 A >5 msec
Resolution:
Inverter sourcing too-much current into the transformer/grid
■ Possible PV Cloud-effect induced power-spike coupled to marginal tap settings and/or rapid grid-voltage drop (local excessive power demands)
1. Check transformer taps for proper set-up ratio can indicate incorrect MV-transformer or mains’ transformer taps
2. Check inverter current-transformers CTA/B/C wiring
