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
E001 occurs when several AC appliances run together
HOW TO CHECK & CORRECT THIS CAUSE
- Turn AC output off and unplug all AC loads.
- Check each device's nameplate watts.
- Keep combined steady demand within AC180's 1800W rated AC output and account separately for motor/compressor inrush.
- Restart AC output with one low-power known-good device.
How to tell it is fixed: E001 stays clear with compatible load, then add appliances one at a time without exceeding rating.
02
E001 happens only as fridge/pump starts
HOW TO CHECK & CORRECT THIS CAUSE
- Choose lower-startup-current loads or power that device separately.
- Its brief startup draw can greatly exceed running watts even when nameplate steady watts look safe.
How to tell it is fixed: No E001 when starting that load on appropriate power.
03
E001 occurs empty, with no AC load
HOW TO CHECK & CORRECT THIS CAUSE
- Stop using AC output.
- Report unloaded repeatable E001 to BLUETTI for inverter/measurement-stage service rather than keeping a reset loop.
How to tell it is fixed: Qualified repair returns stable unloaded and loaded AC output.
