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.

01
E088 follows storage in freezing weather
HOW TO CHECK & CORRECT THIS CAUSE
- Disconnect loads, bring sealed power station into a dry temperature-controlled environment and allow gradual warming within the manual's discharge temperature range (-20°C to 40°C).
- Prevent condensation before use.
How to tell it is fixed: Code disappears and output runs normally.
02
Unit warmed but E088 persists
HOW TO CHECK & CORRECT THIS CAUSE
- Do not heat directly with fire/heater or bridge battery sensor.
- Contact BLUETTI service for temperature sensing/BMS diagnosis.
How to tell it is fixed: Unit reports normal temperature without E088 after service.
