Safety: Keep the enclosure closed. Never bridge output terminals, bypass protective cutoffs or probe the internal battery/inverter. Disconnect external devices before inspecting plugs. Stop if a connector is melted, wet or physically damaged.
Applies to this exact equipment
AC180 only. Confirm the AC180 nameplate and regional AC outlet voltage; AC180P/AC180T specifications must not be substituted. The error names here are from the AC180 User Manual, §5.2.
Version check: Check AC180 versus AC180P: ratings, wiring and error-code tables may differ.

01
Car outlet stops after prolonged high-load running
HOW TO CHECK & CORRECT THIS CAUSE
- Turn the DC output off, disconnect accessory and allow the unit and socket to cool in unobstructed ambient airflow for several minutes.
- Do not chill with water.
How to tell it is fixed: Error clears and outlet accepts a lower-demand accessory.
02
Repeated E068 with rated load in hot environment
HOW TO CHECK & CORRECT THIS CAUSE
- Move to shaded ventilated location and reduce sustained DC load.
- Ensure fan inlets are not blocked.
How to tell it is fixed: The outlet no longer overheats during intended use.
03
Immediate E068 from cold start
HOW TO CHECK & CORRECT THIS CAUSE
- Potential temperature sensing/output hardware fault.
- Stop DC output and request model-specific service.
How to tell it is fixed: Stable normal output after repair without bypassing temperature protection.
