Fault Codes

Fault Code VFD Text Fault Description

8000 0000 Power Module Generated by the power electronics to protect the module.

4000 0000 Power Module Generated by the power electronics to protect the module.

1000 0800 PLL Fault

The inverter was unable to match the grid frequency. This is usually

caused by an unstable power grid.

1000 0400 AC Voltage High The grid voltage exceeded the limits in Table 3-2.

1000 0200 AC Voltage Low The grid voltage dipped below the AC limits in Table 3-2.

1000 0100 AC Freq Low The grid frequency went below the limits in Table 3-2.

1000 0080 AC Freq High The grid frequency went above the limits in Table 3-2.

1000 0020 DC Voltage Low

The DC voltage is below the startup voltage. This fault is only seen in

conjunction with another fault (ex. 1000 0220 is an AC low and a DC

low fault). DC could be low because of low light conditions or the DC

disconnect is turned off.

1000 0010 DC Voltage High

DC Voltage is above 500V. Turn the DC disconnect off immediately.

The inverter will restart when the voltage is back within safe operating

conditions.

1000 0002 Power Supply +15 Housekeeping DC power supply 15VDC is out of tolerance.

1000 0001 Power Supply +5 Housekeeping DC power supply 5VDC is out of tolerance.

0400 0000 Ground Fault

The inverter detected that the GFI fuse is blown. This fault requires an

AC power cycle to reset.

0200 0000 Power Low

The inverter shut down because it was producing less than 60W for 5

minutes. It will try to restart in 10 minutes.

0100 0000 CPU Fault

The inverter encountered a problem in the CPU. This fault requires an

AC power cycle to reset. If this fault reoccurs, contact PV Powered

Technical Support for service.

0040 0000 Over Current Safety protection.

0020 0000 Pre-charge

The inverter experienced trouble starting up the transformer. If this

reoccurs, contact PV Powered Technical Support for service.

0004 0000 Heatsink Temp

The heat sink is above or below the operating limits of -15

F to 200

(-25

C to 95

C).

0002 0000 Watchdog Fault

The CPU experienced a watch dog fault. This fault requires an AC

power cycle to reset. If this reoccurs, contact PV Powered Technical

Support for service.

0001 0000 Ambient Temp

The temperature detected inside the inverter is outside the normal

operating limits of -15

F to 200

F (-25

C to 95

C).
