Have you noticed your Sharp JH1600 solar inverter isn’t working properly? Has it developed a d-27 fault?

What is a d-27 fault?

This is an electrical fusion caused by excessive voltage transients on the input or output of the inverter. It is generally caused by an extraneous event such as a lightning strike or a power surge on the grid.


Will my warranty or household insurance cover a d-27 fault?

Sharp’s warranty does not cover d-27 faults. However, depending on your household insurance policy, you may be able to make a claim with your insurer. If Origin installed your Sharp JH1600 inverter, they may be able to help. However, it can be a very long process.


What is the best way of resolving a d-27 fault?

Should you wish to send your inverter back to Sharp for inspection, Solargain can assist with the process. However, in our experience, a d-27 fault is generally not covered under warranty, so most people are better off buying a new replacement unit straight up. This is particularly so if you also calculate the out-of-warranty repair costs, plus the price of having your solar power system offline for a month, which is roughly how long it can take to have your system repaired through Sharp.

We recommend you replace your faulty inverter with a 1.5kW model inverter - the Fronius Galvo 1.5 is a worthwhile choice. It comes with a great warranty and is just the right size to replace your Sharp JH1600 with. Plus, if you decide to make a claim against your home insurance policy, we are happy to assist any way we can.

At this point, it is also worthwhile considering whether to upgrade to a bigger inverter to increase the output of your solar power system. We can guide you through this process, taking into account your current system and your future power needs.
