- It lists 33 manufacturers and separates user-safe checks from technician-only actions.
Field notes
The homepage organizes the reference by four equipment families and provides alternate routes through manufacturers, fault codes, and symptoms. Its displayed examples include grid faults, battery and BMS errors, charging failures, red lights, and communication problems. The project reports 33 manufacturers and 24 symptom guides, while some recent entries visibly retain a “pending official confirmation” status. A methodology section says model-specific meanings are connected to manufacturer documentation where possible.
