Corrective measures:
Operating manual
• Verify the plausibility of the error message.
• Replace the battery if necessary.
• Check the battery.
• Disconnect the loads, start the generator, start the Sunny Island and charge the battery.
• 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.
• Start the installation assistant and configure a new system with external energy
management (e.g., system with lithium-ion battery).
• Charge the battery.
• Ensure that all battery cells are functional.
