Resolution

Customer's logger (SLV210699556) lost its control-device mapping after a firmware update. Restarted the logger, re-ran the inverter pairing sequence, and reselected Sunsynk from the brand list. SOC/charge/discharge readings returned to normal within 2 minutes. No hardware fault found.

Affected logger: SLV210699556
