• Energy bill higher than usual?

• Installer gone broke?

• Out of manufacturer’s warranty by just a few months?

Sunny Roo Products have been causing huge problems with customers as their inverters are often fault ridden. The company has been placed in receivership and therefore, no warranty exists with any of their products.If your Sunny Roo Solar Inverter screen has a fault alarm code AL09, then the inverters voltage waveform is unbalanced.

Please note that these are general tips only and are based on our current and past experience and therefore, not specific to your solar inverter problem. What we usually find is people trying these troubleshooting tips and if these fail, they give us a call and we can perform diagnostic tests and provide a solution.

• 50% of the time it’s a quick easy fix for any solar tech…

• Error messages and fault codes that are due to an external fault elsewhere in the solar system.
• The solar system is tricking the inverter into thinking it has that error or fault.
• External faults are relatively easy to find and repair. Once fault is repaired, the inverter is back online.

• Other 50% of the time

• There is a fault, which requires more diagnostic type of testing to locate the fault. Out of these about 1 in 4 can be solved onsite. Things like a dodgy install or water damage somewhere.
• The rest of the time it’s the inverter that’s the problem. 1 out of every 2 times the inverter can be sent away for repairs or we can organise those repairs under warranty with the manufacturer, and…
• The rest of the time the inverter was of low quality and either not fixable of not good value to fix. If this is the case we would quote on an inverter with similar specs to replace it with. Getting your system back online fast with high quality parts.
• In the worst case scenario, rare ground leakage faults are very difficult to find and fix but we have also had experience locating these aswell.
