Although Sunna is no longer in business, you may still have a Sunna solar inverter as an important part of your solar system.
Sunna solar inverters are reliable products but can have errors and problems just like all other brands. We have listed out some of the most common ones below however if you are having ongoing solar system issues, or require some further assistance, give Static Electrics a call today on07 3497 5076.
Common Sunna Inverter Error Codes
- Er22: This is a fault that indicates a relay failure. This will likely mean that your solar inverter will require replacing.
- Er10: This is a fault indicating that the inverter is over temperature. The suggested action is to move your inverter to an area with a lower temperature.
- Er11: This fault indicates that the AC condition is outside the range that the inverter allows (e.g. your grid voltage). Call your local solar expert about this.
- AL00/AI01/AL02/AL03: Again, this fault indicates that the AC condition is outside the range that the inverter allows (e.g. your grid voltage). If this is a permanent fault, the internal fuse or AC board may be internally damaged. Call your local solar expert about this.
- AL08/AL13: This fault indicates a utility issue. Check your solar supply switch to see if it is on and, if it is, one of your isolators may be the problem. It could also signify an internal fuse or AC board being damaged. These faults can be caused by surges, so if you have had a storm recently, this could be the cause.
- AL11: This fault indicates an isolation fault. This can be caused by water getting into some part of your solar installation. Call your local solar expert about this.
If your solar inverter is ‘dead’ and not responding, it is best to call a solar expert such as Static Electrics to assist. Without having a full inspection, it is difficult for a proper conclusion to be reached.
