This repair guide for Sunny Roo solar energy system inverters aims to assist troubleshooting. It’s not intended to be a comprehensive user guide.

Unit Description

Your Sunny Roo inverter comes with an LCD and LED display, which show its operation information, as well as its status. It also has a solar array input, which is basically a plug-and-play connector terminal that is intended for the connection of the solar modules. However, you have to take note that the SR1500TL, SR2000TL, and SR3000TL models only have a single PV string input.

Your unit also comes with a standard communication port which is EPO and RS232, as well as an optional communication port slot for USB, RS485, dry contact, or TCP/IP. It also has an AC output terminal for the utility supply.

Installation Manual

While your inverter can be repaired in case you encounter problems with it, the bad news is that the manufacturer doesn’t offer any warranty for their products. To increase your chances of getting it working, make sure that you seek the services of CEC accredited electricians who have the expertise and experience in handling various solar inverters.

Nevertheless, it is worth considering having your unit replaced with a new solar inverter that offers a full warranty even just for a couple of years for you to avoid additional service expenses in the future.

Inverter Warranty

The XPower 450 only needs to be plugged into the 12V lighter socket in your vehicle or connected directly into its battery and you will already have ample power to run your basic electronic appliances. Rest assured that you won’t have to worry about a depleted battery because this inverter can automatically sense low battery voltage. This inverter model is also designed with corrosion resistance and short-circuit protection, making it ideal for damp and humid environments.

Common Sunny Roo Error Codes

When your inverter experiences a fault, an error code will most likely be displayed on its LCD screen. This will allow you to identify what is wrong with the inverter for you to be able to address it promptly or relay the problem to a seasoned electrician immediately.

The most common error codes experienced by Sunny Roo inverter owners often have the prefix ER or AL. Error codes that begin with ER indicate an error in the inverter itself while error codes that begin with AL indicate a grid fault alarm. You will be able to find more of these error codes, as well as how to resolve them, in your user manual. However, keep in mind that you need to get in touch with a serviceman promptly should these errors still persist after following the instructions in the manual.


Error code AL14 is a grid fault alarm code that indicates that there is no utility or a failure in the waveform of the utility.


Error code ER22 means a failure or abnormal behaviour in the output relay. For a quick fix to resolve this error, make sure to disconnect all PV (+) or PV (-). Just wait for a couple of seconds until the LCD of the inverter powers off.

From there, reconnect all the PV (+) or PV (-) and check whether the error code is still showing. Hopefully, a reboot clears out your problem.

But then again, if the error code above persists, better gather some information about your inverter’s installation date, model number, as well as its serial number before you get in touch with a CEC certified electrician. In doing so, you will have a good idea of whether it is worth repairing your unit or perhaps it will be better to have it replaced with a new inverter that is covered with a full warranty.

To find out if your inverter is covered under warranty, first establish when the warranty period began. This is generally the date the system was installed.

The most common inverter warranty period we see is 5 years. However we recommend checking your paperwork as extended warranties are not uncommon and some manufacturers offer up to 10 years – we can assist you with the manufacturer warranty claim process.

Don’t worry. This information is available from your local electricity generator, which is Energex in South East Queensland, Ergon in North and regional Queensland and Essential energy for Northern New South Wales.
