Common Faults with Sharp Inverters

F-00: Utility over voltage

When you see this error code in the display of your inverter, then it is most likely that your system is experiencing high grid voltage levels. What you can do in this case is to check your main solar supply switch and ensure that it is turned on. From there, you may want to call a seasoned solar panel technician to come and check your system.

In case you intend to file a warranty claim for this type of fault, then you would need to send your inverter to a designated service centre. This entails the need for you to disconnect it from your system for it to be shipped accordingly. From there, the service centre personnel will inspect it and identify whether your unit qualifies for repairs or it warrants a replacement. Otherwise, you may need to shell out a significant sum to have it repaired, which can take around a month. For this reason, purchasing a new inverter to replace your faulty one may be a more viable solution.

E21 -> d-21: Output over current and E27 -> d-27: Relay open

A d-21 error code or a d-27 error code that appears on the display of your inverter screen indicates an excessive voltage transient either in the input or the output of your inverter. This can be caused by a power surge on the grid or even lightning. Unfortunately, this type of fault is not covered by the warranty of your Sharp inverter. Nevertheless, you may claim against your home insurance policy instead, but you need to check with your insurance provider.

In case you encounter any of the d-faults listed above, it is best that you have your system checked by licensed electricians. They will be able to confirm whether an excessive voltage transient is occurring and they will also be able to install a replacement unit if necessary. Alongside this, they will also be able to assist you should you wish to send your inverter back to a Sharp service centre for inspection.

Nevertheless, because the d-faults are generally not covered by Sharp’s warranty, the cost of your inverter repair may prove to be more than the sum that you need to shell out in buying a new inverter. Thus, most homeowners who experience these types of faults have their inverter replaced with a new unit instead. In doing so, they often go for a bigger inverter with the capacity to provide a greater output from your solar power system.

Other Faults

Aside from the error codes that you may encounter with your Sharp inverter, some other faults that can happen to your system include the following:

Frequency Issues

Error codes F-02 and F-03 signifies a utility frequency over or under respectively. In case the fault is intermittent, you need to lodge the error with your power distributor.


Error codes F-06 and F-07 entail the need for you to get in touch with an electrician for them to conduct anti-islanding tests on your solar power system.


This code simply means an over voltage in your solar panel array, which is most likely to happen during midday, wherein a wattage peak occurs. However, if this occurs frequently, even during the early morning or late afternoon, then you may need to get in touch with an electrician for him to conduct a health check on your solar power system.

E15 -> d15

This is one of the few faults that may be covered by your inverter’s warranty. This code indicates relay sticking, which is usually intermittent. It is often the case that it precedes the d-27 error, which is no longer covered by warranty. Therefore, it is best to have your unit checked immediately as soon as this error code appears on the display screen of your inverter.

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.
