SUNNY ROO SR SERIES COMMON ERROR AND FAULTS
AL05 alarm code on the screen of your Sunny Roo inverter?
If you have an AL-05 Alarm Code on a Sunny Roo, Beyond Building or Sunna Inverter please check out the following on what you can do about it.
Sunny Roo Inverter AL05 Alarm Code
AL means Alarm and 05 is the code, so an AL05 message is Alarm code 5. AL05 means that Input A 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 A of the inverter.
- There is no solar panels connected to input A.
If you check under the inverter you will see Input A and Input B. If Input A is not connected to any cables then the AL-05 code is nothing to worry about – it’s normal as there is no voltage on input A for the inverter to detect.
If you do have cables plugged into Input A of the inverter and you are getting AL05 message then you do have a problem.
What to do with an AL05 Alarm Code on a Sunny Roo inverter?
If there are cables plugged into input A 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.
If you need further assistance with your Sunny Roo inverter AL05 Alarm Code issue please complete the form above and we’ll assist you further.
AL07 alarm code on the screen of your Sunny Roo inverter?
If you have an AL07 Alarm Code on a Sunny Roo inverter please check out the following on what you can do about it.
Sunny Roo Inverter AL07 Alarm Code Display
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 AL07 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 AL07 Alarm Code on a Sunny Roo 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.
Is your Sunny Roo inverter displaying an AL14 error message on the screen?
At SAE Group we’ve seen a large number of Sunny Roo inverters displaying the AL14 fault message. According to the Sunny Roo inverter manuals the AL14 fault message means that “the waveform of utility is fail”. Now isn’t that helpful to know?
Sunny Roo Inverter AL14 Alarm Code Display
What it means in plain English is the Sunny Roo inverter has detected an issue with the AC power feeding into the inverter from your switchboard; now this could be the case or it could be a failure inside the inverter – from our experience unfortunately it tends to be the latter.
What can you do about a Sunny Roo inverter AL14 Fault?
The first thing you can try is rebooting your solar power system:
- Turn OFF the Solar Supply Main Switch in the switchboard.
- Turn OFF the PV Array DC Isolator beside the inverter.
- Wait for the Sunny Roo or Sunna inverter screen to go blank and then a few more seconds.
- Turn the PV Array DC Isolator beside the inverter back ON.
- Turn the Solar Supply Main Switch in the switchboard back ON.
- Wait for the inverter to reboot.
- See if the AL-14 fault has cleared.
If the reboot has not cleared the AL14 fault then it looks like you will require the assistance of a professional solar power accredited electrician. Please contact us through the contact form above and we’ll assist you further.
Er00 Error code on Sunny Roo solar inverter
It is quite a common issue here at SAE Group to see faulty Sunny Roo solar inverters and one of the errors which we see is the Er00 error code. With this issue, the Er00 code is displaying on the screen and the green light will be flashing intermittently. If working properly, the green light should be constantly lit.
Sunny Roo Inverter Er00 Error Code Displayed on Screen
According to the Sunny Roo inverter manual this error is due to the inverter being in soft start procedure, but the DC Bus cannot reach and maintain anticipative charging voltage. In layman’s terms, the solar inverter is not functioning properly and it needs to be fixed ASAP.
What can you about a Sunny Roo Inverter Er00 Error?
The first thing to do is try rebooting the system, it’s important to carry out the shutdown procedure as follows:
- Turn off the AC Solar Supply Main Switch located in the switchboard or the Inverter AC
- Isolator at the inverter.
- Then turn off the DC PV Array Isolator locator next to the inverter.
- Wait for approximately 1 minute.
- Turn on the AC Solar Supply Main Switch or Inverter Isolator.
- Turn on the DC PV Array Isolator.
- Check if this clears the error.
Unfortunately, since the Sunny Roo company is no longer around the warranty is no longer valid if this issue persists. Although you can potentially get the inverter repaired, you will still have to pay quite a bit of money to do this and you’ll be left with an inverter of inferior quality without any warranty.
At SAE Group we recommend having the faulty Sunny Roo inverter replaced with a good quality inverter that will operate for years to come and be covered by a full warranty, giving you peace of mind for years to come.
If you need further assistance with your Sunny Roo Inverter Er00 Error Code issue and you’re near the Gold Coast or Brisbane area please contact us through the form above and we’ll be in touch. We have quality replacement solar inverters in stock ready to be delivered to your door.
At SAE Group we have seen several instances of a Sunny Roo inverter Er19 Error Code issue. When you see an Er19 error code the Sunny Roo inverter manual states that there’s a DC BUS discharge fail or that the capacitors of the DC Bus can’t be discharged down. This usually means there is an an internal error with the inverter. If this happens the green light will be flashing and the solar power system is not working. In this case you will want to take action without any delay.
Sunny Roo Inverter ER19 Error Code Display
What Can You Do About a Sunny Roo inverter Er19 Error Code?
It is best to try rebooting the system to see if will clear the fault. When rebooting the system, it’s important to carry out a proper shutdown procedure as shown below:
- Turn off the SOLAR SUPPLY MAIN SWITCH or the Inverter AC Isolator (if applicable).
- Turn off the PV Array DC Isolator located at the inverter.
- Wait for approximately 1 minute.
- Turn on the SOLAR SUPPLY MAIN SWITCH or AC Isolator (if installed).
- Turn on the PV ARRAY DC Isolator.
- Wait a few minutes for the inverter to restart.
- Check to see if the error has cleared.
If the issue has not cleared, unfortunately, the Sunny Roo manufacturer is no longer around so any warranty will no longer be covered or honored. If you decide to have the inverter repaired, you’re still going to spend a lot of money and have an inferior quality unit without warranty as it could still fail the following day. We recommend having it replaced with a new inverter that includes a full warranty instead. If you go with this option, it is important to check the size of your inverter found on the side panel.
If you need further assistance with your Sunny Roo inverter Er19 Error Code issue please contact us through the contact form above.
Is your Sunny Roo solar power inverter showing an Er22 error code on the screen?
The Er22 error code is telling you that the output relay inside the Sunny Roo inverter has failed. The course of action that the Sunny Roo inverter manual recommends to take for an Er22 fault is to turn the inverter off and wait for the inverter LCD screen to go blank.
Sunny Roo Inverter ER22 Error Code Display
When the LCD screen is blank, restart the inverter and see if the fault has cleared and if the system resumes operation.
In our experience it is very rare that a Sunny Roo inverter actually resumes operation after being rebooted from an Er22 fault as the output relay does not tend to fix itself! If you find that the Sunny Roo inverter continues to show the Er22 fault after being rebooted you really only have 2 choices:
- Get the inverter repaired.
- Replace the inverter with a quality replacement.
Your Sunny Roo inverter options
- Repair the inverter – You may feel that this option would be the cheapest option to get your solar power system operational again however is tends to end up being quite expensive as you need to:
- Pay to have an electrician disconnect the inverter.
- Pay to send the inverter to a reputable repair shop.
- Pay for the repairs.
- Pay to have the inverter returned to you.
- Pay to have an electrician reconnect the Sunny Roo inverter.
All the above is not going to leave you any change from $500, and after all of that you still have an inverter that is of inferior quality with no warranty as the manufacturer has disappeared. Your best option may be the second option.
- Replace the inverter with a quality replacement – A quality replacement inverter is the best way to go, yes it will cost a bit more up front but it will give you a reliable inverter and a warranty from a company that should be around to back it if it’s required in the future.
Quality Replacement Solar Power Inverters
We are really saddened to see the number of people that have been left with solar power systems that are not operational by Sunny Roo and others using inferior components. If you are one of these people with a solar power system that is not functioning due to a faulty inverter we can supply and install a quality replacement inverter for you as quickly as possible; we fully understand that a solar power system that is not operational is a liability rather than the asset it should be.
The old saying comes to mind, “Quality is remembered long after price is forgotten”.
Is there an Er29 error code on your Sunny Roo inverter screen?
An issue we’ve seen a few times with the Sunny Roo inverter brands is the Er29 Error Code. When you have an Er29 error message on one of these inverters it will attempt to reboot the system and go through a startup procedure. While it’s starting up the green light will be flashing, this start up process will usually take 1 to 2 minutes. You will hear a relay clicking inside the inverter as well.
Sunna Inverter Er29 Error Code Display
According to the Sunna solar inverter manual the Er29 message means that the DC current is over the specifications of the inverter, but in our experience it tends to be an internal problem with the inverter causing the issue. Technically a solar power system which has been installed for years, that’s been working fine and has not been modified cannot suddenly put out a DC current which is too high; so it all points to an internal issue with the inverter.
How to troubleshoot an Er29 Error Code on a Sunny Roo inverter?
As mentioned above the Er29 error is most likely due to an internal error with the inverter so the best thing to do initially is to try rebooting the system in the hope it may clear the fault. When rebooting the system it’s important to carry out the shutdown procedure as shown below:
- Turn off the AC Solar Supply Main Switch located in the switchboard or the Inverter Isolator at the inverter.
- Then turn off the DC PV Array Isolator locator next to the inverter.
- Wait for approximately 1 minute.
- Turn on the AC Solar Supply Main Switch or Inverter Isolator.
- Turn on the DC PV Array Isolator.
- Check if this clears the error.
If the inverter is consistently coming up with this error code it will need to be repaired or replaced. Unfortunately the warranty can no longer be used because the Sunny Roo company has disappeared and is no longer in business. The best action to take is to have the inverter replaced with a good quality replacement unit that will serve for years and be covered by a full warranty. You can try to have the inverter repaired but you’ll still have to pay around $500 and you’re still left with an inferior quality inverter with no warranty, leaving you in the future with more potential problems that are not covered under warranty.
Is your Sunny Roo inverter displaying an Isolation Fault message on the screen?
Are you having an Isolation Fault issue with your Sunny Roo inverter? If so you’ve come to the right place – we can help.
Sunny Roo SR4000TLI Solar Inverter Isolation Fault Display
Aside from the red fault light being lit, you will also see an Isolation Fault message on the inverter screen. The Isolation Fault message could possibly be a problem with the power from the solar panels or it could be an impedance problem, but in most cases we’ve seen the Isolation Fault message on a Sunny Roo inverter it has ended up being due to an internal fault with the inverter. If you see this message it’s best to contact a solar accredited electrician to have a look at the system to work out what the root cause of the problem is.
What can you do about a Sunny Roo inverter Isolation Fault issue?
It’s always a good practice to reboot the system to see if that clears the error. To do this it’s important to follow the shutdown & startup procedure below:
- Turn off the SOLAR SUPPLY MAIN SWITCH or Inverter AC Isolator (if installed).
- Turn off the PV Array DC Isolator located at the inverter.
- Wait for approximately 1 minute.
- Turn on the SOLAR SUPPLY MAIN SWITCH or AC Isolator (if installed).
- Turn on the PV ARRAY DC Isolator.
- Wait a few minutes for the inverter to restart.
- Check to see if the error has cleared.
If the issue has not cleared you will certainly need some professional help.
If after having your system tested it’s found that the inverter is the problem you have two options:
- Get the faulty inverter repaired.
- Replace the faulty unit with a good quality replacement inverter.
If you decide to have the inverter repaired you’re still going to spend a lot of money and have an inferior quality product that’s not covered by any warranty. The Sunny Roo inverter manufacturer is no longer around as they went into liquidation a few years ago so any warranty will no longer be honored. We recommend having the faulty unit replaced with a quality new inverter that has a full 5 or 10 year warranty – it may initially cost a bit more but in the long term it will certainly provide you with the best value for money.
