Event number
Message, cause and corrective measures
9324
Battery error
Current battery capacity (SOH) is below 70%.
Corrective measures:
• Verify the plausibility of the error message.
• Replace the battery if necessary.
9325
Battery error
A 20% recalibration of the battery state of charge has been performed with a jump of more
than 10%.
Corrective measures:
• Check the battery.
9326
Battery error
Battery protection mode 1, 2 or 3 is activated.
Corrective measures:
• Disconnect the loads, start the generator, start the Sunny Island and charge the battery.
9331
Battery error
Battery voltage in the Sunny Island at Lxx is above the permissible measurement range.
Corrective measures:
• Check whether the value set for the parameter
Battery voltage
is above 65.0 V. If the
value is above 65.0 V, check the settings of the DC sources and ensure that the battery
capacity is sufficient. Observe the technical data for the battery at the DC connection.
• Ensure that the DC sources are correctly connected and configured.
• For off-grid systems: ensure that all SMA inverters are configured to the country data set
for stand-alone mode.
9332
Battery error
External battery management has been detected but not configured.
Corrective measures:
• Start the installation assistant and configure a new system with external energy
management (e.g., system with lithium-ion battery).
9333
Battery error
Measured battery voltage in the Sunny Island at Lxx is below the permissible measurement
range. The usable battery capacity may be too small, e.g., due to aging.
Corrective measures:
• Charge the battery.
• Ensure that all battery cells are functional.
