Why does my SMA SUNNY BOY 4000TL show unstable operation (Event 3301 to 3303)?
If your SMA Inverter displays unstable operation (Event 3301 to 3303), it means there is not enough power at the DC input of the inverter for stable operation. 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.
What does DC overvoltage (Event 3401 to 3402) mean on my SMA Inverter?
If your SMA Inverter displays a 'DC overvoltage' error (Event 3401 to 3402), it means the DC input voltage connected to the inverter is too high. Disconnect the inverter from the PV array immediately. Check that the DC voltage of the strings is in compliance with the input voltage range of the inverter before reconnecting the inverter to the PV array. If the voltage is within the permissible input voltage range, the inverter may be defective. Contact the SMA Service Line.
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.
Why did parameter setting fail (Event 7105) on my SMA SUNNY BOY 4000TL Inverter?
If your SMA Inverter reports that parameter setting failed (Event 7105), it is not possible to set parameters via the SD card. Check the parameters for valid values and ensure change rights via SMA Grid Guard code.
What to do if SMA SUNNY BOY 4000TL Inverter shows system disturbance (Event 202 ... 205)?
If your SMA Inverter displays a system disturbance related to Event 202-205, this means that the mains voltage has fallen below the permissible range. Check whether the miniature circuit-breaker has tripped. 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.
What does it mean if my SMA SUNNY BOY 4000TL displays 'Unstable operation (Event 3301 ... 3303)'?
If your SMA Inverter displays 'Unstable operation (Event 3301 ... 3303),' it means there is not enough power at the DC input of the inverter for stable operation. 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.
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.
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 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.
What causes installation fault (Event 1101) on SMA SUNNY BOY 4000TL Inverter?
If your SMA Inverter displays 'Installation fault' (Event 1101), a second phase is connected to N. Correct the connection.
