What you will see
- Fault 03 after new batteries were fitted
- Fault 08 with a lithium battery that has no data cable
Why it happens
If the battery bank does not match the inverter's battery voltage, or charge settings do not match the battery, voltage climbs too high.
Diagram
Battery and settings must match
Matched
