Battery troubleshooting
Record what the system displays and when the issue first appeared so a qualified technician can assess it.
Record the event
- Note the time, operating mode and equipment that displayed the message.
- Copy the complete message and identify the battery, inverter or charger model that showed it.
- Describe what changed since the last normal operation, including recent service or a configuration change.
Identify the document set
Locate the manual revision for each affected unit. The same display label can have different meanings on different equipment. Ask for the exact-model instructions before interpreting a message.
Hand over safely
Keep enclosures closed. Do not bypass BMS protections, change protection settings or disconnect equipment to collect information. The qualified site operator should determine the next action using the applicable instructions.
For an immediate hazard, follow the site emergency procedure. Use this form for routine technical review.
