If you have a Sharp inverter and it’s showing a D-27 or D-21 error message, unfortunately you’re going to have to replace it with a different brand inverter. Sharp inverters are no longer available or supported in Australia and Sharp themselves won’t even consider repairing an inverter with one of these error codes.
In Sharp’s own wording, a D-21 or D-27 error has been caused by “an extraneous event” meaning something external to the inverter such as a lightening strike.
At the time of writing this post, we have replaced 5 JH-1600E’s within a week and we have another 4 to replace in the next week. What’s interesting is, all the calls came in to us after a major storm with thousands of lightening strikes throughout the Adelaide metro area. It can’t be just coincidence that all these failures happened around the same time as a thunderstorm and it’s our belief that all the failures were due to the storm conditions.
In all cases, we have replaced the Sharp inverters with Fronius Galvo because the electrical specs of the Galvo match those of the Sharp perfectly. By this I mean the input DC voltage range is similar between the two brands which negates the need to check panel models and panel electrical data. The Fronius Galvo is the perfect replacement for damaged Sharp JH-1600E inverters.
Other benefits of using Fronius Galvo is their extended warranty. Until further notice, Galvo inverters come with a standard 5 years full manufacture’s warranty PLUS a 5 year parts only warranty for no extra charge. Combine this with the fact that Galvo inverters can be repaired on site (on your wall) by someone like us who is a Fronius Service Partner. These are all good reasons as to why we use Fronius Galvo to get broken systems up and running again.
If your Sharp inverter has broken down, give us a call and we’ll help you through the process of replacement and get your system running and saving you money again.
I hope this post has helped you.
