ALM Diode leuchtet - Felermeldung Busspannung zu hoch.

1 comments:
Mr. Anderson

When the ALM diode lights up on the Pylontech US5000-B and there is a bus voltage error, it indicates a possible reverse connection of cables. The solution is to power off all batteries and inverters, disconnect the breaker, and check the cable connections. If no alarm appears when turning on a single module without cables, the issue is likely a reverse connection.
