JFY Inverters In Australia

In 2018, Australia's Clean Energy Council (CEC)  de-listed all JFY inverters from its approved products list after a model failed testing for compliance with AS 4777-2. Failing the Passive Anti-islanding test posed a potential safety issue as the inverter may not shut down under some grid fault conditions. Other issues were also detected and the CEC considered results of the model tested as indicative of other models until demonstrated otherwise.

JFY lodged an appeal regarding the decision, but the appeal was denied.

Warranty Information

If you have a JFY inverter that is no longer functioning, the warranty may not be of much use given the company no longer has a presence in Australia. However, if you still have warranty coverage and your installer is still around, they are responsible for honouring it. Aside from that, it's not worthwhile getting one repaired elsewhere - bite the bullet and buy a new one. Check out SQ-recommended budget inverter brands.

This inverter was installed (5kW) in 2013. When I sold the house 10 years later, it was still performing as expected. I see a lot of people having issues with this brand, but the worst that happened to mine is the display has become a little hard to read. Not surprising as its on the west wall of the house.

We. chose a JFY because its budget focused which still ticks the boxes with guarantee and performance. With technology and policy changing around solar so much, we also didn't want to invest with an expansive inverter in case it doesn't sync with a future battery systems. Just only 12 months on and we are looking to upgrade the 5kW system to 10kW because we are now allowed to by the government, so who knows what the futures is.

Suntwins 3300TL. The contract plan was to split the 12 panels into two sets of 8 and 4 on two different roof sections. The installing technician persuaded me that it would be better to arrange them as a single array of 12 on the northerly facing roof section. This he did but as he did not have with him a single inverter and we were 100km from from his supply, the only sensible option was to install the twin inverter I had paid for, with capacity for extra panels should I need them at a later date.

I do not know whether I should be rating the inverter POOR or not. See next section

These inverters are absolute rubbish. They typically stop working (no power returned to the grid). This is apparently a very common problem with them. When this happens the inverter doesn't indicate an error, so unless you check regularly for zero or near zero power for the day, they can provide no value for years before the fault is detected.

This should be ZERO stars.
Absolute crap.
Unfortunately the retailer shut up shop so I cant get any help.
I bought a 5kw system with 2 x 2.5kw inverters.
The retailer advised me up front the inverters occasionally fail but JFY would replace "No questions Asked" and at half the price they thought they were the best option.
Well the first replacement was needed after 6 months while the retailer was still open and it took 6 months to get replaced. Shortly after that the second one failed and that took another 6 months to replace. Now 4 years after the initial installation one of the replacement inverters has failed and JFY have not responded despite emailing and facebook messages every week for 6 months.
DO NOT BUY ANYTHING MADE BY JFY

Had our solar installed 5 years ago. From day 1 our power bills were still high, but we thought it was due to the pool. We run everything during the day. Our power bills keep growing, last one Oct 2020 $850. Contacted SAE, each time there is a wait of a weeks for a response. Now they want me to register it on this website and provide all this information that I have no idea what it is and connect it to wifi. Sent instructions that are so brief I can't follow them. Still waiting for someone to get back to me, meantime our power bill rises.

SunTwins inverter 5 Kwh connected to 3 Kwh of panels. Failed within less than 5 years. Both electricians who have found it faulty have said "these are rubbish I've replaced hundreds of them". 2 Totally separate qualified and C.E.C accredited electricians saying exactly the same thing.I Have emailed JFY TECH 15 times got 4 replies directing me to another email address within the same company that does not exist. I have rang the 1300496278 number listed on their website, never gets answered or goes to message bank not a single call back. I took photo's of my computer screen and sent it to [email protected]. This company is THE WORST COMPANY I HAVE EVERY DEALT WITH.
I was told by my insurer after trying to get my inverter replaced under warrantee for more than 3 months to give them until close of business Friday 24/07/2020. If they still haven't responded with a replacement or a date for replacement (within a reasonable time frame) make a claim on my home and contents insurance and they will have it replaced then pursue JFY TECH for my excess, the cost of having 2 electricians look at it (already refunded), the unpaid time off work to give electricians access to the inverter, the increased cost of my electricity bill. etc. DO NOT DEAL WITH THIS COMPANY. Unless you want cheap rubbish components and endless headaches when it fails in less than 5 years. I truly mean this DON'T DEAL WITH THIS COMPANY.

Would have given 0 Stars but that option was not offered. Our inverter stopped working under warranty - took months to get a replacement, we had to pay for the installation of the replacement which was a used one in a scratched case. This one keeps failing but at the moment starts up again when restarted. We complained the day it was installed and they agreed to replace it with a new one - but that was nearly a year ago and we have kept emailing them to ask when the new replacement will be here and we keep getting excuses like this one: "For our store do not have the JSI 2000TL replacement inverters, the next shipment will arrive in Syndey about the middle time in Nov. Then we will send a good looking and working well replacement inverter JSI 2000TL to you at first time. Sorry for it trouble you so much, my friend. "
Always a promise of a new delivery time and "sorry for trouble you so much, my friend". This company is terrible to deal with, we kept getting lies after lies after lies - and no replacement inverter. AVOID AT ALL COSTS.

I have 2 jfy inverters fail within just under 6 years. the first was repaired under warranty after failing within 3 years. i had to pay the labour cost for the replacement. replacement new unit failed again just under 3 years. installer said hard company to deal with so if I want to have a go myself, try it. I said not good enough and the installer said "well that's how it works in the solar industry" the people I spoke to on the phone could not care less

Since 21/12/2016 I have been trying to have my JFY inverter replaced, whilst still under , warranty, today 26/4/17 a technician arrived, from a contract company, Go Solar, he had a refurbished unit and advised me that to his knowledge no warranty came with it. After a phone call to JFY service, Fanny advised me she had no supervisor and could not supply me with a contact number for JFY manufacturing instead she hand balled me back to my installer, Solar Naturally, I am now waiting for a call from their operations manager, phone tennis is not fun. I will keep you all updated. Wish me luck,but stay away from JFY.

1.5kW inverter at the rental property, looks like the first inverter lasted 3 years before dying, to over 6 weeks to get another one under warranty, this one lasted 3 weeks and has done 148kWh. It works in the morning with lower solar output but once it rises the inverter gets a dc leakage. Very unimpressed with the unit and the service centre. Don't buy this brand!!

Had the inverter for 3 years now, and it's not working well at all. It is faulty and when I check its daily total it reads 0kWh. I have checked it's output for the last 3 months and it has only done 7 kW. There service centre is even worse, they are hard to get hold of and when you do they tell you it will take 3-4 weeks to make a decision to send you another inverter, but not a new inverter a refurbished one, just not good enough.

Inverted stopped out putting power. Apparently this is very common. As it's still in warranty I called to get it serviced. I don't think anyone mans the phone as my calls went unanswered over three days. I then logged a service request via the website. A week later I had heard nothing so sent an email asking for an update. 2 weeks later and no reply to my email I call the service phone number and someone answers! Their phone line is very bad and her English is not great. She tells me it takes 3 - 4 weeks to look at my request. She said she couldn't tell me how long it would take to get someone out to look at it as my service request had not been approved yet. The JFY is a very cheap inverter hence why the support is very bad. I have a feeling I will need to do a lot of following up to make them honour their warranty.
