Why SMA SB3.0-1SP-US-41 Inverter is 'Waiting for DC start conditions > Start cond. not met'?
- C
  Christina HobbsSep 8, 2025
  The SMA Inverter displays 'Waiting for DC start conditions > Start cond. not met' because the feed-in conditions for the utility grid are not yet fulfilled. Ensure that the PV array is not covered by snow or otherwise shaded. Wait for higher irradiation. If this message is displayed frequently in the morning, increase the voltage limit for starting grid feed-in by changing the parameter Critical voltage to start feed-in. If this message is displayed frequently with medium irradiation, ensure that the PV array is correctly rated.

What does 'DC overvoltage > Disconnect generator' mean on SMA SB3.0-1SP-US-41?
- X
  xfarmerAug 30, 2025
  The 'DC overvoltage > Disconnect generator' message on your SMA Inverter means there is overvoltage at the DC input. Immediately disconnect the inverter from voltage sources. Check whether the DC voltage is below the maximum input voltage of the inverter. If it is below the limit, reconnect the terminal block with the connected DC conductors to the inverter. If the DC voltage exceeds the maximum input voltage of the inverter, ensure that the PV array has been correctly rated.

What does 'High discharge curr. > Check generator' mean on SMA SB3.0-1SP-US-41?
- A
  allisonleeSep 4, 2025
  The message 'High discharge curr. > Check generator' on your SMA Inverter means that the leakage current of the inverter and the PV array is too high. Check the PV system for ground faults.
