Multi-battery system resets its limits nightly, G100 lockouts
reported in the field
Symptoms
- On a newly installed multi-battery system with a Backup Gateway and three batteries wired over RS485, the inverter briefly goes offline most nights around 11pm to midnight and comes back with its Charge/Discharge limits reset to a default value (11400)
- Its Active Power Limit swings between 100% and 0% through the day and, at zero, halts production with no way for the owner to reset it
- And forcing export from the battery triggers a 'G100 Export restriction' lockout that needs a physical installer-level reset to clear, daily
