What to do if my Deye SUN-20K-SG01HP3-EU-AM2 Inverter shows AC_Overload_Fault?
If your Deye Inverter displays an AC_Overload_Fault, check the backup load connection to ensure it is within the allowed power range.
What does it mean if my Deye SUN-20K-SG01HP3-EU-AM2 Inverter shows DC_Insulation_Fault?
If your Deye Inverter shows a DC_Insulation_Fault, it means the PV isolation resistance is too low. You should check if the connection of PV panels and the inverter is firm and correct. Also, verify whether the PE cable of the inverter is connected to ground.
What should I check if my Deye SUN-20K-SG01HP3-EU-AM2 displays AC_UV_OverVolt_Fault?
If your Deye Inverter displays an AC_UV_OverVolt_Fault, it indicates that the grid voltage is out of range. Check if the voltage is within the specified range. Also, ensure that AC cables are firmly and correctly connected.
What should I check if my Deye SUN-20K-SG01HP3-EU-AM2 Inverter displays AC_UV_UnderVolt_Fault?
If your Deye Inverter displays an AC_UV_UnderVolt_Fault, it indicates that the grid voltage is out of range. Check if the voltage is within the specified range. Also, ensure that AC cables are firmly and correctly connected.
What to do if Deye Inverter displays DC_Inversed_Failure?
If your Deye Inverter displays a DC_Inversed_Failure, check the PV input polarity.
What to do if Deye Inverter shows Grid_phase_warn?
If your Deye Inverter displays a Grid_phase_warn, check the phase sequence connection of the power grid. Try changing the grid type. If there is still no solution check the wiring at the grid end.
What to do if Deye SUN-20K-SG01HP3-EU-AM2 shows VW_activate?
If your Deye Inverter displays VW_activate, measure whether the grid port voltage is too high and check whether the AC cable is too thin to carry current.
What to do if Deye Inverter displays Parallel_comm_warn?
If your Deye Inverter displays a Parallel_comm_warn due to unstable parallel communication, check the connection of the parallel communication line. Ensure that the parallel communication line is not wound with other cables, and check whether the parallel dip switch is on.
What does it mean if my Deye SUN-20K-SG01HP3-EU-AM2 Inverter shows DC_VoltHigh_Fault?
If your Deye Inverter displays a DC_VoltHigh_Fault, it means the BUS voltage is too high. Check if the battery voltage is too high and verify that the PV input voltage is within the allowed range.
What does it mean if my Deye SUN-20K-SG01HP3-EU-AM2 Inverter shows DC_VoltLow_Fault?
If your Deye Inverter displays a DC_VoltLow_Fault, it means the BUS voltage is too low. Verify if the battery voltage is too low. If it is, use PV or the grid to charge the battery.
