Sunny Roo Beyond Building and Sunna Inverter AL07 Alarm Code

AL07 alarm code on the screen of your Sunny Roo, Beyond Building or Sunna Inverter?

If you have an AL07 Alarm Code on a Sunny Roo, Beyond Building or Sunna Inverter please check out the following on what you can do about it.

AL means Alarm and 07 is the code, so an AL07 message is Alarm code 7. AL07 means that Input B on the inverter is under voltage. When this alarm code is shown it means one of two things:

There is a problem with the solar panels connected to input B of the inverter
There is no solar panels connected to input B

If you check under the inverter you will see Input A and Input B. If Input B is not connected to any cables then the AL-07 code is nothing to worry about – it’s normal as there is no voltage on input B for the inverter to detect.
If you do have cables plugged into Input B of the inverter and you are getting AL07 message then you do have a problem.

What to do with an AL-07 Alarm Code on a Sunny Roo, Beyond Building or Sunna Inverter

If there are cables plugged into input B then ensure these cables are properly plugged in and that all the Solar DC Isolators are turned ON.

If you’ve tried this and the alarm code continues to appear then you’re going to need to contact a local solar accredited electrician to find out what’s going on. It could be a problem with the solar inverter or it could be a case of it’s not getting power from the solar panels on the roof.
