Guides
- Deye SG04LP3: how to read the alarm code and alarm history
A solid red Alarm LED means a fault or warning. The code appears on the home screen; details are in the System Alarms menu and the Device Info page. Note them before calling the installer.
- How to restart a Deye SG04LP3 inverter safely (and when to stop)
A restart helps with temporary faults. Use the switches, not the cables: DC and AC switches off, wait one minute, switch on again. If the code keeps returning, call the installer.
- Deye SUN-SG04LP3: what the DC, AC, Normal and Alarm LEDs and the panel keys mean
The panel has four indicators, four function keys and a display. Solid green DC, AC and Normal mean PV, grid and inverter are fine; solid red Alarm means a fault or warning.
