Decoded

Reports AC overcurrent, high DC injection; look at inverter bridge, AC cable; do: AC connection check, contact manufacturer service.

What can be behind AC overcurrent

Failure modes that present as the reported condition, and the tests that tell them apart.

What can be behind High DC injection

Failure modes that present as the reported condition, and the tests that tell them apart.
