What to do if the SMA SUNNY TRIPOWER 12000TL-US Inverter displays 'Update file defect.'?
If your SMA Inverter displays 'Update file defect.', the update file on the memory card is defective. Reformat the memory card and re-save the files to the memory card.
Why is my SMA SUNNY TRIPOWER 12000TL-US Inverter's power output reduced (Derating occurred)?
If your SMA Inverter has reduced its power output (derating occurred) for more than ten minutes, it is likely due to excessive temperature. Clean the cooling fins on the rear of the enclosure and the air ducts on the top using a soft brush. Also, clean the fans and ensure that the inverter has sufficient ventilation.
Why is my SMA Inverter 'Waiting for DC start conditions'?
If your SMA Inverter is 'Waiting for DC start conditions', the feed-in conditions for the utility grid are not yet fulfilled. 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 Minimum voltage input or A.VStr, B.VStr. If this message is displayed frequently with medium irradiation, ensure that the PV array is correctly rated.
How to fix 'PE conn. missing' error on SMA SUNNY TRIPOWER 12000TL-US?
If your SMA Inverter displays a 'PE conn. missing' error, it means the grounding conductor is not correctly connected. Ensure that the grounding conductor is correctly connected.
What does 'Insulation resistance > Check generator' mean on my SMA SUNNY TRIPOWER 12000TL-US?
If your SMA Inverter displays 'Insulation resistance > Check generator', it means the inverter has detected a ground fault in the PV array. Check the PV system for ground faults.
What should I do if my SMA SUNNY TRIPOWER 12000TL-US Inverter says 'SMA Grid Guard code invalid'?
If your SMA Inverter says 'SMA Grid Guard code invalid', the SMA Grid Guard code entered is incorrect. Enter the correct SMA Grid Guard code.
What to do if my SMA SUNNY TRIPOWER 12000TL-US shows 'Timeout in communication for reactive power spec.'?
If your SMA Inverter displays 'Timeout in communication for reactive power spec.', communication to the system control is absent. Ensure that the connection to the system manager (e.g. Sunny Home Manager) is intact and that no cables are damaged or that no plugs have been pulled.
What to do if my SMA SUNNY TRIPOWER 12000TL-US Inverter shows 'Timeout in communication for cos-Phi spec.'?
If your SMA Inverter displays 'Timeout in communication for cos-Phi spec.', communication to the system control is absent. Ensure that the connection to the system manager (e.g. Sunny Home Manager) is intact and that no cables are damaged or that no plugs have been pulled.
Why does my SMA SUNNY TRIPOWER 12000TL-US show 'Unstable operation > Abort self-test'?
If your SMA Inverter shows 'Unstable operation > Abort self-test', there is not enough power at the DC input of the inverter for stable operation. If irradiation is too low, wait for it to increase. If this message is displayed frequently, ensure that the PV array has been correctly rated and wired.
What to do if the SMA SUNNY TRIPOWER 12000TL-US says 'SD card defective'?
If your SMA Inverter displays 'SD card defective', the SD memory card is not formatted. Re-format the SD memory card and re-save the files to it.
