Decoded

Reports grid undervoltage, grid loss; look at AC cable; confirm with grid voltage measurement; do: AC connection check, grid settings check, utility company consultation.

What can be behind Grid undervoltage

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