How to restart a Deye SG05LP1 inverter safely (and when to stop)

Summary (editorial)

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.

✎ editorial – written from the cited sources, not a manufacturer statement. Status: draft.

From the manufacturer's documentation (English source wording, with page)

  1. Turn off DC and AC switch, wait one minute, turn on DC/AC switch[1]
  2. On/Off button on the left side of the case[2]
  3. AC and DC circuits disconnected separately; maintenance personnel wait before working (5 minutes – label table, read from page image)[3]
  4. Disconnect all wires before any maintenance[4]

⚠ Work on refrigerant circuits, mains electricity and PV DC wiring is for qualified technicians only.
