Message, cause and corrective measures
Changing of grid parameters not possible > Ensure DC supply
This error can have the following causes:
• The parameters to be changed are protected.
• The DC voltage at the DC input is not sufficient to run the main CPU.
Corrective measures:
• Enter the SMA Grid Guard code.
• Ensure that at least the DC start voltage is available (green LED is
flashing, pulsing or glowing).
SPS AC overvoltage
An AC source has been connected to the socket connection for secure power
supply operation.
Corrective measures:
• Check the connection at the SPS slots, and make any necessary
corrections.
Short circuit in the SPS power outlet
The maximum initial load has been overshot or the appliance's initial current is
above the maximum permissible load current of the connection for secure
power supply operation for more than 5 s.
Corrective measures:
• Reduce the load at the connection for secure power supply operation.
• If necessary, select an appliance with a lower initial current.
Time synchronization failed: [x]
No time information could be called up from the set NTP server.
Corrective measures:
• Ensure that the NTP server was configured correctly.
• Ensure that the inverter is integrated into a local network with Internet
connection.
