What to do if my SMA Inverter says 'Parameter file not found or defective'?
If your SMA Inverter says 'Parameter file not found or defective', the parameter file was not found or is defective. Copy the parameter file to the correct folder again.
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.
What should I do if my SMA SUNNY TRIPOWER 12000TL-US displays 'Param. setting failed'?
If your SMA Inverter displays 'Param. setting failed', parameters could not be set using the memory card. Ensure that the parameters are set correctly and that the SMA Grid Guard code is available.
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 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.
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 should I do if my SMA SUNNY TRIPOWER 12000TL-US displays a 'DC overvoltage' error?
If your SMA Inverter displays a 'DC overvoltage' error, it indicates overvoltage at the DC input. Immediately disconnect the inverter from all voltage sources. Check if the DC voltage is below the maximum input voltage of the inverter. If it is, reconnect the DC connectors to the inverter. If the DC voltage is above the maximum input voltage, ensure that the PV array has been correctly rated or contact the installer of the PV array. If this message is repeated frequently, contact the Service.
What does 'DC overcurrent > Check generator' mean on my SMA SUNNY TRIPOWER 12000TL-US Inverter?
If your SMA Inverter displays 'DC overcurrent > Check generator', it indicates overcurrent at the DC input. If this message is displayed frequently, ensure that the PV array has been correctly rated and wired.
What does 'Resid.curr.too.high > Check generator' mean on my SMA SUNNY TRIPOWER 12000TL-US Inverter?
If your SMA Inverter displays 'Resid.curr.too.high > Check generator', the inverter has detected a residual current due to temporary grounding of the PV array. Check the PV system for ground faults.
What does 'High discharge curr. > Check generator' mean on my SMA SUNNY TRIPOWER 12000TL-US?
If your SMA Inverter displays 'High discharge curr. > Check generator', it means the leakage currents of the inverter and the PV array are too high. Check the PV system for ground faults.
