• Energy bill higher than usual?

• Installer gone broke?

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

Sharp is a household name for most electrical appliances. Sharp have outsourced warranty claims for their inverters and have little support for inverters out of warranty. We have been able to help with warranty claims and organise replacement parts from them but it is a difficult process that needs to be followed.

• 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 as well.
