Gold Coast Solar Power Solutions used to be a service agent for Sharp for their JH1600e solar power inverters until Sharp changed their service model, so if you’re on the Gold Coast and own a Sharp inverter and it develops a fault you can contact us here and we’ll get your solar power system back in action ASAP.

When a Sharp JH1600 inverter has a fault it usually comes up with a error or event code to explain what’s wrong; the following table lists these codes so you can get an idea on what your inverter is trying to tell you and what you can do about it.
Sharp JH1600 Inverter Fault Codes Beginning with F-
Sharp JH1600 inverter fault codes beginning with F are caused by the power from the street (the grid) being outside the inverters operating parameters. The Sharp JH1600 inverter reacts by disconnecting from the grid and attempts to switch on again after the specified mains monitoring period, as long as no further errors occur during this period. When the grid conditions are again within the inverters operating parameters the inverter should reconnect to the grid and continue operation.
Code |
Error Description |
| F-00 | Utility over-voltage |
| F-01 | Utility under-voltage |
| F-02 | Utility frequency over |
| F-03 | Utility frequency under |
| F-06 | Anti-islanding (frequency over) |
| F-07 | Anti-islanding (frequency under) |
| F-08 | Miss utility synchronal lock signal |
| F-09 | Frequency abnormal (50<->60 Hz) |
Sharp JH1600 Inverter Fault Codes Beginning with P-
Sharp JH1600 inverter codes beginning with P specify that the voltage coming from the solar panels is outside the inverter parameters.
Code |
Error Description |
| Solar panel array under voltage (<60 V). The screen is blank in this case, as this happens everyday when the sun goes down. | |
| P-11 | Solar Panel array over voltage (>320 V) |
Sharp JH1600 Inverter Fault Codes Beginning with E- or d-
Sharp JH1600 fault codes beginning with E or d are error states that are more serious. These errors always start as E codes but when the fault continues it will change to a d code. They are either temporary or lasting faults and are triggered by faulty hardware or a software problem. Try switching off the inverter following the system shutdown procedure, leave off for a few minutes then attempt to restart. If the fault continues please contact your local solar power experts such as Gold Coast Solar Power Solutions for further assistance.

Error Description |
| E15 -> d-15 | Relay sticking |
| E16 -> d-16 | Communication error |
| E17 -> d-17 | Aux-power abnormal |
| E18 | Ground fault |
| d-20 | Temperature sensor broken |
| E21 -> d-21 | Output over current Learn more about the D-21 error here |
| E22 -> d-22 | DC offset over rating |
| E23 -> d-23 | Fin high temperature |
| E26 -> d-26 | DC/DC converter abnormal |
| E27 -> d-27 | Relay open Learn more about the D-27 error here |
| E28 | DC bus voltage abnormal |
| d-40 | EEPROM abnormal |
If you have a Sharp JH1600e inverter that is out of warranty or coming up with a D-27 or D-21 error code the best thing to do is replace the inverter. Gold Coast Solar Power Solutions recommend Fronius inverters as the best replacement for your Sharp inverter.
Fronius are an Austrian manufacturer of solar inverters and are well known for their quality and fast response to warranty claims. If you are on the Gold Coast or South Brisbane and your Sharp inverter is giving you problems then contact us here or give us a call on 07 55 228 980 – we are here to help ensure that your solar power system remains an asset rather than a liability!

Hi.
firstly, let me thank you for providing such an informative site! Really handy info
I bought a house a few years ago on the NSW South coast. It has a solar system installed that I think is quite old.
It still appears to be delivering really well but the inverter has a problem.
It is a Sharp JH-1600E.
When I bought the house the inverter display (blue 7-segment LED) had one or two bars missing, but I could guesstimate the output.
However now, the display is blank. No amount of persuasion will light any segment.
The inverter seems to be working ok, as in plenty of output power according to my bills.
However to really see what it is delivering I need to be able to read total output etc.
I see you used to sell these units. Are spare parts available for these? For example, the display unit/PCB?
Or, would another 7-segment display work?
A was an electronic Engineer for 40+ years, so working on this type of equipment is not beyond me, but I dont want to tackle this unless parts and diagrams etc are available.
I realise it would be cheaper to replace the inverter if I had to have it repaired for me, so I am exploring the options.
What are your thoughts?
Thanks,
Jeff
Hi Jeff, Thanks for the encouragement. Unfortunately, we have no stock of those screens that we could supply. Though your inverter isn’t showing anything on the display, like you said, it could still be working 100% fine on the power side. If your inverter is in direct sunlight most of the day, this can degrade the LCD screen in a very short time. I’d suggest that you keep a close eye on your energy bill to make sure that the inverter is still performing. Should you have any issues we are more than happy to supply a replacement inverter in the future that doesn’t need a screen and you can monitor your solar production via WiFi or cable connection.
