# What do the different lights mean on the Dura-i G3 Inverter?

Displayed on the front view of the Dura-i G3 is an LED indicator, which shows the status of the inverter. For more details on what each light colour means, see below:

**Solid green** - This indicates that your Dura-i is in working order

**Flashing green** - A flashing green light on your Dura-i G3 inverter means the system is in standby mode and not actively providing power.

**Solid Blue** - If your Dura-i G3 inverter has a blue light, this often means it's in off-grid mode, or there may be a system fault.

**Solid Red** - A solid red light on your Dura-i G3 inverter indicates that a fault has occurred

If any of the three warning lights are on, please follow the steps below.

1. Make sure all breakers and switches (for PV, battery, and AC) are securely on, and check for any obvious loose cables or visible damage around the inverter.
2. If the alarm happens only once and goes away after a restart or reset, the inverter should return to normal operation by itself.
3. If the red light keeps coming back or the inverter will not work, stop and contact the installer who originally fitted your system.

**Safety note:** Never open or attempt internal repairs on the inverter. If you’re not sure what to do, it’s always best to get support from a qualified technician.
