SD card defective, SD memory card defective

SMA inverters log event 7113 when the memory card is full or write-protected. On STP-TL-US units, event 7101 reports a defective SD card, and the stated cause is a card that has not been formatted. Other SMA manuals say event 7101 means the micro SD card in the inverter is faulty and should be replaced. SMA describes the 71xx events as faults during an inverter update from the SD card. The fix is to reformat the card, save the files to it again, and replace the card if needed. Don't confuse this with event 7106, a defective update file, or event 7105, where parameters could not be set from the card and the inverter keeps feeding the grid. On Sunny Island units, the display can show that the card is full, has an invalid format or is incompatible. Updates fail on unsupported cards, so use a card of at most 2 GB formatted as FAT-16. Check first whether the card is full or write-protected. Then reformat it, and replace it if the event comes back.

The memory card is full or write-protected

On Sunny Island, the display can show that the SD card is full, has an invalid file format, is incompatible, or is not inserted.

review note: support check: partial - Display shows full, invalid format, incompatible, and a 'no card inserted' status exists (CardStt Off), but the passages don't tie these to 'not writable' explicitly, and the Sunny Island display's 'not inserted' is from a parameter, not the display list.
