What causes installation fault (Event 1101) on SMA Inverter?
- VVictor SullivanSep 4, 2025
If your SMA Inverter displays 'Installation fault' (Event 1101), a second phase is connected to N. Correct the connection.

If your SMA Inverter displays 'Installation fault' (Event 1101), a second phase is connected to N. Correct the connection.
How to check ground fault on SMA SUNNY BOY 3600TL?
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 3600TL 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 does it mean if my SMA Inverter 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 SUNNY BOY 3600TL Inverter displays 'PE conn. missing (Event 901)'?
If your SMA Inverter displays 'PE conn. missing (Event 901)', the PE connection is missing. Check the AC installation.
What to do if SMA SUNNY BOY 3600TL 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.
Why is my SMA SUNNY BOY 3600TL Inverter waiting for DC start conditions (Event 3901 to 3902)?
If your SMA Inverter displays 'Waiting for DC start conditions' (Event 3901 to 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 do varistors fail in my SMA Inverter?
Varistor failure in your SMA Inverter is likely due to factors that affect all varistors, such as temperature, age, or induced overvoltages. The solution is to replace all the varistors with new ones, ensuring they are installed correctly.
What does it mean if my SMA SUNNY BOY 3600TL Inverter says 'Inst. code invalid (Event 9002)'?
If your SMA Inverter displays 'Inst. code invalid (Event 9002)', the SMA Grid Guard code entered (personal installer password) is not valid. Enter a valid SMA Grid Guard code.
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.
