- SStephanie MontgomerySep 7, 2025
If your SMA Inverter displays a 'Control system fault', contact the installer.
What should I do if my SMA SUNNY BOY 6000TL?US displays 'Control system fault'?
If your SMA Inverter displays a 'Control system fault', contact the installer.
What to do if SMA SUNNY BOY 6000TL?US Inverter shows grid failure?
If your SMA Inverter indicates a grid failure, first ensure that there is no failure in the power distribution grid or that the AC miniature circuit-breaker has tripped. If the problem persists, contact the installer.
What should I do if my SMA SUNNY BOY 6000TL?US indicates overvoltage at DC input?
If your SMA Inverter indicates an overvoltage at the DC input, contact the installer.
What to do if SMA SUNNY BOY 6000TL?US Inverter displays AFCI test failure?
If your SMA Inverter displays an AFCI test failure, try restarting the inverter. If the message appears frequently, contact the installer.
What to do if my SMA SUNNY BOY 6000TL?US shows overvoltage at DC input and risk of inverter destruction?
If your SMA Inverter shows overvoltage at DC input and there is a risk of inverter destruction, immediately turn the rotary switch of the DC Disconnect to the Off position. After this action, contact the installer.
What to do if my SMA SUNNY BOY 6000TL?US displays 'High leakage current'?
