10 Error messages and trouble shooting
Number Message Possible cause Solution
F44 HW CT C Fail Internal failure. Call Delta Support.
F01, F02,
F03
HW DC Injection
Grid waveform is abnormal.
Check the grid waveform. Grid connection of
inverter needs to be far away from non-linear
loads if necessary.
Internal failure. Call Delta Support.
F15,
F16,
F17
HW DSP ADC1,
HW DSP ADC2,
HW DSP ADC3
DC input voltage is below the minimum required
DC voltage.
Check the DC input voltage on the inverter dis-
play.
Maybe the solar irradiation is too low.
Internal failure. Call Delta Support.
F20 HW Efciency
The calibration is incorrect. Check the accuracy of current and power.
Internal failure. Call Delta Support.
F06,
F08,
F09,
F10
HW NTC1 Fail,
HW NTC2 Fail,
HW NTC3 Fail,
HW NTC4 Fail
Ambient temperature is > 90 °C or < -30 °C. Check the installation environment.
Detection circuit malfunction. Check the detection circuit inside inverter.
F18,
F19
HW Red ADC1,
HW Red ADC2
DC input voltage is below the minimum required
DC voltage.
Check the DC input voltage on the inverter dis-
play.
Maybe the solar irradiation is too low.
Internal failure. Call Delta Support.
F50 HW ZC Fail Internal failure. Call Delta Support.
F27 RCMU Fail Internal failure. Call Delta Support.
F13, F29 Relay Open Internal failure. Call Delta Support.
F28 Relay Short
Internal failure. Call Delta Support.
The driver circuit for the relay malfunction. Check the driver circuit inside inverter.
F05 Temperature High Ambient temperature is > 60 °C. Check the installation environment.
