If your Sharp inverter is causing you issues, or you just need to have it serviced, you‘ve come to the right place.. Solargain can certainly help when it comes to Sharp inverter servicing and repairs. We’re able to guarantee honest advice and quality workmanship so that you can get back to enjoying the benefits of your solar energy system. Get in touch with our friendly service team and we’ll let you know how we can help.
Our stringent and time-tested repair process for Sharp solar inverters gives you peace of mind that your system will be maintained to the highest standards.
In most cases, once our specially-trained technicians have visited your property and inspected your inverter, they will contact the manufacturer for replacement parts and repair the faulty parts themselves or recommend a new system.
While our strict safety and labour standards keep our service quality high, Solargain’s national coverage and strong manufacturer relationships keep prices down.
F-00: Utility over-voltage
This type of fault can indicate high grid voltage levels. You should check that the main ‘solar supply’ switch in your metre box is switched on. If it is, we recommend you then call us for assistance.
Will my warranty or household insurance policy cover an F-00 fault?
Unfortunately, Sharp doesn't offer much support for this type of fault. If you wish to make a warranty claim, you will need to disconnect your unit and send your inverter off to a designated service centre in Sydney. They will inspect it and decide whether it qualifies for repairs or replacement under warranty. If your system isn’t covered, you can pay $300 for an out-of-warranty repair job. This process usually takes around four weeks and is often more expensive (once you take into account your system’s downtime) than simply purchasing a new replacement inverter, so when this does occur, you may want to consider upgrading your system.
What’s the best way of resolving an F-00 fault?
Solargain is happy to assist you in returning your faulty inverter to Sharp for repairs or replacement of the unit. However, the out-of-pocket expenses involved in this process are usually higher than buying a new inverter. With this in mind, we recommend you replace your faulty Sharp inverter with a 1.5kW solar power inverter. The Fronius Galvo 1.5 is our pick as it comes with an excellent warranty and is the perfect size to replace the Sharp JH1600. Replacing it will not only generally be cheaper, it will also involve a lot less downtime, so you’ll be back to benefiting from solar all the sooner.
It is also worth considering upgrading to a larger capacity inverter to make the most out of your solar power system’s energy output. To get the ball rolling, simply give us a call on 1300 73 93 55 or get in touch with us.
E21 -> d-21: Output over current or d-27: Relay Open
This is caused by excessive voltage transients on the input or output of the inverter. It is highly likely that an external factor such as lightning or a power surge on the grid caused this issue.
Will my warranty or household insurance policy cover a d-21 or d-27 fault?
If it is clear that your inverter is suffering from a d-21 fault, it will not be covered by Sharp’s warranty. Extraneous events like lightning strikes and power surges are rarely covered under warranty due to how unlikely they are to occur. However, you may be able to make a claim on your home insurance policy. You will need to check directly with your insurer but we are happy to assist you with this so don’t hesitate to give us a call.
What’s the best way of resolving a d-21 or d-27 fault?
The simplest way to replace your faulty Sharp inverter is to arrange for an inverter health check with us. One of our qualified technicians will inspect your system, confirm if a d-21 fault is occurring and, if so, can install a replacement unit that same day. We recommend replacing this particular model with a 1.5kW solar power inverter. The Fronius Galvo 1.5 is a great choice as it is covered by an excellent warranty and is a similar capacity to the Sharp JH1600, making the transition easy for your home solar energy system.
If you would like to make a claim on your home insurance policy, we’re happy to walk you through the process. You may want to consider upgrading your unit to a larger inverter to achieve greater energy output from your solar power system. Contact us online today to arrange your solar inverter health check or speak with one of our friendly customer service representatives by calling 1300 73 93 55.
For more information on how to solve these problems and for a comprehensive list of all Sharp inverter faults, see below
|F-00||Utility over-voltage||If the AC isolator and the solar supply main switch located in the meter box are on, the problem could come from the AC fuse. If the fault appears intermittently, it is indicative of a high grid voltage issue (exceeding 255V), and shall be reported to the power distributor. However, if it is a constant error, the inverter needs to be replaced. To find out what the problem is and how to address it, contact Solargain for a solar maintenance service.|
|F-01||Utility under-voltage||If the isolator and the solar supply main switch located in the meter box are on, the problem could come from the AC fuse. We recommend you book a system health check. Please note there will be an additional $20 charge.|
|F-02||Utility frequency over||If this fault is intermittent, it needs to be lodged with the power distributor as a frequency issue.|
|F-03||Utility frequency under||If this fault is intermittent, it needs to be lodged with the power distributor as a frequency issue.|
|F-06||Anti-islanding (frequency over)||We recommend you book a health check in order to have an electrician conduct anti-islanding tests.|
|F-07||Anti-islanding (frequency under)||We recommend you book a health check in order to have an electrician conduct anti-islanding tests.|
|F-08||Miss utility synchronal lock signal||If the solar supply main switch located in the meter box is on and there is power to all three phases of the house, then there may be a power distributor issue. We recommend that you contact Solargain to book a health check.|
|F-09||Frequency abnormal (50<->60Hz)||If this fault is intermittent, it needs to be lodged with the power distributor as a frequency issue.|
|P-11||Solar Panel array over voltage (>320V)||If this is happening in the midday, then it simply means that the wattage is peaking. If it's occurring constantly, including early morning or late afternoons, then there may be a fault. Contact Solargain for a system health check.|
|E15 -> d-15||Relay sticking||This fault, usually intermittent, often precedes a d-27 error, which can mean the beginning of a terminal issue. Your inverter may be eligible for warranty replacement.|
|E16 -> d-16||Communication error||This could mean that the inverter has connected in the wrong order. Follow the manual shutdown procedure to reset the inverter.|
|E17 -> d-17||Aux-power abnormal||Your inverter may be eligible for warranty replacement.Your inverter may be eligible for warranty replacement.|

The Sharp JH1600E is a 1.6kW inverter sold between 2012 and 2013 in Australia by Sharp Corporation, a Japanese company. They offer limited warranty support in Australia and contract their repairs to a company called "Inverter Service", which can be contacted by email at firstname.lastname@example.org.
If you own a Sharp inverter and would like to have your unit inspected, Inverter Service will arrange for your inverter to be picked up and sent to their Service Centre in Sydney in order to disassemble the unit and diagnose the fault. Sharp will then make a decision about a warranty repair. If they decide not to repair the inverter free of charge, then you have the option to proceed with an out-of-warranty repair, i.e. have your inverter repaired and returned to you within 4 weeks for $300. Between the cost and downtime, this often works out to be more expensive than purchasing a new replacement unit. Besides, your repaired inverter will only be guaranteed for 12 months, whereas a new unit will come with a full standard warranty (usually 5 years). A Sharp JH1600E can be directly replaced with a Growatt 1.5 or a Zeverlution 1.5. This makes upgrading your system something to genuinely consider.
Please note that, in the case of d-27 and d-21 faults, the manufacturer's warranty won’t apply. However, in some instances, insurance claims can be made against these faults anyway. We can provide a letter detailing the nature of the fault, for you to take directly to your insurer, who will then make an assessment as to whether or not your policy covers the claim.
The Sharp unit is hardwired, which means a qualified electrician must attend site to remove/replace the unit. To book a site visit, please contact us.
If you aren’t one of our existing customers, you are not on the 40-cent feed-in tariff (as we installed those inverters from 2012, when this feed-in tariff was no longer available), so you could benefit from an upgrade and increase your system's capacity (i.e. greater inverter capacity and extra panels, mean more power for your home or business).
Solar power is and will always be a fantastic long-term investment that can help you substantially cut greenhouse emissions and reduce your electricity bills. In order to ensure you get the greatest possible from your system we strongly recommend that you regularly monitor your inverter. Checking your inverter’s yield is the most important part of this process.
If you have a Sharp inverter, a green ‘On-Grid’ light should be lit, indicating that the unit is working normally. You can track your system’s performance using the second and third menu options. Use the Select button (to the right of the screen) to scroll through the various menu options. The menus will be displayed in the following order: The second display provides you with a daily kilowatt hour reading. Since it is a daily reading, the best indication of production will be towards in the early evening before the sun has set.the end of the day, before the sun goes down.
You can check this figure against the figures provided to you in your Solargain Customer User Manual given to you in a black handover folder on the day of installation. This will give you an idea of if your system is producing less energy than it should be. If you can’t find this manual please call 1300 73 93 55 and we’ll arrange to have a new one sent to you.
The third display is a cumulative total of your kilowatt hours since the system was installed and first became active.
To work out your average monthly production, simply record the difference between your E-Total figure at the start and end of each month.
- E-Total on 1st January is 1100
- E-Total on 1st February is 1300
January’s Monthly Yield is therefore 200 units (1300 less 1100)
January’s Average Daily Yield is therefore 6.45kwh (200 monthly yield divided by 31 days in January)
Like the E-Today figure, this data can also be compared to the yield estimates in your Solargain Customer User Manual to get a picture of what your system should be producing.
Sometimes in the morning and late afternoon, as the inverter is turning on or off, it will display a red light or the On-Grid light may be flashing or it might be making a clicking noise, this is a part of normal processes, so you shouldn’t be worried by it. The inverter may also make a clicking noise. This is completely normal. The inverter will also get louder as you work throughout the day. You should also note that the inverter’s sound increases as it works harder and produces more wattage. Any internal issues with the inverter will be detected by the device and will cause the fault light to be displayed permanently, it is only then that you should be concerned and investigate the fault.
If there’s ample sunlight outside and your inverter is displaying a red fault light, you will need to conduct a reset. Instructions explaining how to reset your inverter are available here.
If, after conducting a reset, the red light is still on, please retrieve the error code displayed on the screen as well as your serial number from the side of your inverter. Then contact us on 1300 73 93 55 and we will happily assist you to resolve the issue.
Please note - if you have no power in your house due to a blackout, then your inverter will not work until the grid has been restored.
