Mokka-e High-Voltage System Error

My 2022 Vauxhall Mokka-e is throwing a high-voltage system error after 100545 km. Now I get the 'Error stored in the error memory' message, the engine shuts off, and power is reduced. Suspect the battery, maybe heavily discharged or defective?

Sounds familiar. I've got a Mokka-e too. Had similar symptoms - power loss and errors. Any inverter issues?

Inverter issues? How would I know? The error code just mentions high-voltage system.

The inverter converts DC to AC power. If it's faulty, it can cause voltage drops and those error messages. I would visit a workshop to diagnose. Probably an electrical fault.

Cheers. Took it to the shop. Turns out it was a dodgy battery cell. Replaced it, cost 290€, all good now.
