What should I check if my Deye SUN-15K-SG01HP3-EU-AM2 Inverter displays AC_UnderFreq_Fault?

If your Deye Inverter displays an AC_UnderFreq_Fault, it means the grid frequency is out of range. Check whether the frequency is in the range of the specification. Also, check whether AC cables are firmly and correctly connected.
