What do Huawei LUNA2000 battery alarms like 3005 or 3047 mean?
Short answer
LUNA2000-S0 alarms use IDs 3000-3061. 3005 means the battery DC switch is off or the DC bus cable disconnected; 3047 is battery pack or cell undervoltage, which needs prompt charging; 3008/3009 are over/under-temperature; 3061 means end of life. Huawei's fixes involve DC switches, so call your installer (LUNA2000 manual Issue 17, checked 24 September 2026).

What does this mean?
3011 undervoltage warning: battery charges when sunlight is sufficient or AC charging is allowed. 2068 'Battery Abnormal' is raised on the inverter side.
What should I do first?
Record the code and current battery state before changing settings. Follow only the owner-safe reset steps in the manual.
When do I need an engineer?
Use an installer or manufacturer support route if the fault returns, involves isolation or protection, or the manual does not give an owner reset.
What to do next
If the system is hot, smoking, damaged or making unusual electrical noises, move away from it and follow the manufacturer emergency guidance.
