Why does my SMA SUNNY BOY 4000TL say 'DC overcurrent (Event 3801 ... 3802)'?
If your SMA Inverter indicates a 'DC overcurrent' (Event 3801 ... 3802), the inverter switches off due to an overcurrent on the DC side. If this event occurs frequently, check the design and the circuitry of the PV array.
What to do if my SMA SUNNY BOY 4000TL displays 'Waiting for DC start conditions (Event 3901 ... 3902)'?
If your SMA Inverter displays 'Waiting for DC start conditions (Event 3901 ... 3902),' the input power or voltage of the PV modules is not yet sufficient for feeding into the electricity grid. Wait until irradiation is higher. If this event recurs at medium irradiation levels, check the PV plant design and the correct circuitry of the PV array.
How do I fix overheating (Event 6501 to 6502) on my SMA SUNNY BOY 4000TL?
If your SMA Inverter is showing a self-diagnosis overheating error (Event 6501 to 6502), the inverter interrupts feed-in operation due to interior overheating. Ensure sufficient ventilation and check heat dissipation.
How to check ground fault on SMA SUNNY BOY 4000TL Inverter?
To check for ground faults on your SMA Inverter, indicated by event number '35', '36' or '37': 1. Open the Sunny Boy. 2. Measure the voltages between the plus and minus pole of a string against the ground potential. If a voltage is present, there is a ground fault in the corresponding string. 3. Repeat step 2 for each string.
What to do if my SMA SUNNY BOY 4000TL is waiting for grid voltage?
If the SMA Inverter shows a 'Waiting for grid voltage' error, it means there's no mains voltage at the AC output. First, check the fuse and replace it if necessary. Then, inspect the AC installation and check for a general power failure.
How to fix system disturbance (Event 101 to 103) on SMA SUNNY BOY 4000TL?
If your SMA Inverter is experiencing a system disturbance (Event 101 to 103), it indicates that the mains voltage has exceeded the permissible range. You should check the mains voltage and grid connection on the inverter. If the mains voltage is outside the permissible range due to local grid conditions, you can ask your network operator if the voltage can be adjusted at the feed-in point or if it would be acceptable to change the monitored operating limits. If the mains voltage is within the tolerance range, yet this error is still displayed, contact the SMA Service Line.
What to do if SMA Inverter shows system disturbance (Event 202 to 205)?
If your SMA Inverter displays a system disturbance (Event 202 to 205), it means the mains voltage has fallen below the permissible range. Check if the miniature circuit-breaker has tripped. Also, check the mains voltage and grid connection on the inverter. If the mains voltage is outside the permissible range due to local grid conditions, ask your network operator if the voltage can be adjusted at the feed-in point or if it would be acceptable to change the monitored operating limits. If the mains voltage is within the tolerance range, yet this error is still displayed, contact the SMA Service Line.
Why does my SMA SUNNY BOY 4000TL show system disturbance (Event 501)?
If your SMA Inverter is showing a system disturbance (Event 501), it means that the mains frequency is not within the permissible range. Check the mains frequency, if possible, and observe how often major fluctuations occur. If there are frequent fluctuations, ask your network operator if it would be acceptable to change the operating parameters. Discuss the proposed parameters with the SMA Service Line.
What causes system disturbance (Event 701) on SMA SUNNY BOY 4000TL?
If your SMA Inverter is showing a system disturbance (Event 701), the mains frequency is outside the permissible range. If possible, check the mains frequency and observe how often major fluctuations occur. If there are frequent fluctuations and this error occurs as a result, ask your network operator if it would be acceptable to change the operating parameters. Discuss the proposed parameters with the SMA Service Line.
How to troubleshoot system disturbance (Event 301) on SMA SUNNY BOY 4000TL Inverter?
If your SMA Inverter is showing a system disturbance (Event 301), it indicates that the 10-minute-average mains voltage is no longer within the permissible range. Check the mains voltage at the termination point of the inverter. If, due to local grid conditions, the mains voltage exceeds the configured threshold, ask the network operator whether the voltage can be adjusted at the feed-in point, or whether it would be acceptable to modify the threshold for power quality monitoring. If the mains voltage is permanently within the tolerance range and this error is still displayed, contact the SMA Service Line.
