- Inverter detects low DCV on internal bus
- Measure DC and AC voltages
- Compare with LCD
- Replace inverter
- Internal damage
- Wire came loose during shipping
Troubleshooting - This error is identifying multiple discrepancies between the Bus voltages. This may be caused by faults occurring on the AC side that requires an internal circuitry check. Some components may be damaged so please note while doing a thorough check.
