Questions and answers
the red alarm shows sometimes what does this mean
The red alarm on the Sofar HYD3000-ES indicates a fault or error condition. Possible causes include battery overvoltage (ID05), grid LVRT fault (ID07), PV voltage too high (ID08), internal faults (ID09-ID26, ID53-ID55), insulation resistance too low (ID56), or overheating issues (ID57-ID59). The appropriate action depends on the specific fault code displayed.
