Sungrow solar inverters review

Sungrow Customer Service: 1800 786 476

Sungrow Power Supply Co Ltd is a Chinese company established in 1997 and operates in several different energy-related niches, including wind power conversion and inverter production for photovoltaic systems and energy storage.

The company claims more than 79GW of Sungrow inverter capacity has been deployed worldwide and that it has 15% global market share.

Sungrow has been present in the Australian solar inverter market since 2012. Its Australian operations are based in North Sydney, NSW, so should you need specific technical assistance, or in case you have any questions about their warranty policies, you can contact Sungrow easily by calling them, sending them an email, or by dropping in if you happen to live in the area.

Depending on their needs, customers can choose from a pretty solid range of solutions, including single-phase inverters such the SG3KTL-M, SG4KTL-M and SG5KTL-M; or three phase models such as the SG3KTL-EC, SG5KTL-EC and SG10KTL-EC.

Sungrow Warranty Notes

Sungrow offers a product warranty of a period of five years from the date of installation and no more than six years from the manufacturing date of a solar inverter - so that's something worth checking.

If you have problems with your Sungrow inverter, your first port of call is the original  installer. Despite what some might say, if the installation company is still in business then they are the ones liable for the repair/replacement of a faulty inverter assuming it is still within its warranty period.

If your original installer is no longer in business or contactable, you'll need to lodge a warranty claim with Sungrow.

In order to do so, Sungrow advise you must arrange an installer to test the solar inverter to determine if it is faulty (Sungrow can help you find someone in your area if you call them on the number listed above). If a fault is confirmed, Sungrow will work with the installer to arrange a replacement inverter. Notably - you are not compensated for the out of pocket cost of the initial testing.

If you own a Sungrow solar inverter, we invite you to share your experience with other visitors to this page by adding your review.

THE APP IS HORRIBLE, does seem to connect, can't view any stats unless I go outside and look at the inverter display panel.

the app also look terrible and in clunky compared to other apps I have seen from ABB etc

I can't really rate the inverter because I don't even know how our system is performing - no comparison.

The inverter is working well as I am now feeding power to the grid, however right from day one I have not been able to connect inverter to wifi hence I can’t track real time usage. Sungrow recently upgraded their app so obviously others were having issues, but I still can’t connect. Disappointing as I chose Sungrow after heaps of research and was excited about being able to track usage.

Having never had solar before, it's hard to know whether what my inverter does is common or not. I receive fault messages every day emailed from the inverter. My installer isn't that keen on providing information on what the faults are and whether they require corrective action, so it has been a learning process for me to keep on top of it.

Inverter performance has been fine. No failures in its primary job, however the app that you can use to monitor performance , output, error messages etc is useless. I've given up trying. I've complained and had it reset by the installer and Sungrow several times but it fails within days. The most unreliable app I have ever downloaded.

Now I believe they are updating or changing this shortly but have not as yet looked into it.

Only time we had a problem was after the new smart meter was installed. Could not reconnect or even login to app. Had to call Sungrow. They had to reset everything as our account had just dropped out. All works fine now. Router always on and inverter just reconects after a black out. One thing, out Chromecast for the telly doesnt work anymore. When I try to connect it, it always trys to connect to the Inverter instead of our router. Strange.

The inverter has been fine after initial setup problems were solved. There seems to be a sweet spot which one string is always in and the other string only part of the time. This is not uncommon for a lot of inverters. On hot days it runs hot even though it is always in shade and efficiency drops a little. Not sure if other brands do the same.

its fully hybrid, which opens up the possibility for using most batteries,
Big Sky Energy, was the only supplier to inform me that this was the only unit on the market, as the others were promoting the Fronius inverter as being able to have batteries connected to them. which is sort of true, but is very limited.

This is a mid level Inverter that has an average (but workable) online data management system compared to the higher end brands such as SMA (which I have on a separate system). The main difference is the SMA version updates live but the Sungrow can be delayed by up to 1 hr.

The Sungrow also has intermittent internet connectivity failures (about once per month) that stop the data upload, which is only rectified by completely shutting down the system and rebooting. I gave up on the WiFi dongle as the connectivity issues were horrible. I now have it hard wired into my network which has made it better.

The inverter also has some thermal management issues with its internal fan. If you leave the front door of the inverter closed, it soon gets quite hot and the internal cooling fan kicks in, running like a demon to try and cool down a space that is dust sealed and enclosed. Of course this means it is blowing hot air around inside itself and doing nothing except screaming away. I have taken to leaving the inverter front panel open during the summer to mitigate this problem, as well as setting up a $9 Bunnings 12v USB fan connected to a USB phone charger, underneath the inverter to push air up onto the heat-sink in order to increase air flow. This is on a timer for peak periods and all of this combined has made a massive difference.

Apart from the above, the inverter does its job well and manages the battery properly and runs the house. If Sungrow can fix their internet connectivity woes and thermal management this would certainly give it a much better rating in my opinion. The price is right for what you get, suggest you ask your supplier for an extended warranty to 10 years as I did. Peace of mind.

Died after one year. Has been impossible to get the company to send me a new one. Constantly saying that hey haven’t got my paperwork or that I have to talk to the first guy I talked to in the phone, and that guy is never available.

I highly recommend avoiding this company.

I initially had problems with the inverter "derating", then after a period driving output to near zero and this required me to power down the unit and reset.
I had a 10 year warranty and this was in the first two months of use!. I picked this inverter company because they have an office in Australia and my install company has it installed at thier factory with no problems. After complaints the inverter was checked and replaced free from charge. As the month of March by this time the weather/sun intensity days head declined and the unit has run well untill now (September) when again it was "derating" with higher sun intensity days which is opposite to what we all want.
I again complained to the company and they informed me that the grid voltage was too high, too much resistance in my consumer mains to the network?
My unit was "derating" because the grid was too high?, I checked that information as I am also an industrial electrician. I found that when the inverter was outputting 255 volts and "derating" the grid was actually 244.8 V. So after a lot of too and fro and Jpeg files sent the Sungrow engineer asked me to change/check settings and issued me with the password.
The system is now frequently outputting 30kw's per day and running well.
If I had not driven the change due to my trade knowledge I feel that I would have been fobbed off!

Company advertised an inverter that would send data to app on my iPhone/iPad. Instead, I did not get this, but a wire tethered remote next to it that is downstairs and away from where I live. I called the company to enquire about this and they admitted it was an oversize and error. They said they would install the proper device the nex time they were in the area. Never heard from them again. It's been a year.

The inverter is 5kWh connected to a 5.6 GCL battery.

The reasons for my average rating for the installation are. The system was ordered in October and requested to to operational before end of December but was not fully operational until mid January. There were two reasons for this delay, 1. Equipment was unavailable for the system, particularly the battery until early December. 2. This was equipment unfamiliar to the installer and after much trial and error GCL technicians were eventually called in to finalise the installation.
I must mention that Heinz was very apologetic and tried to get things moving but it meant a lot of follow up frustration until everything was sorted out.

The inverter is connected to a Reposit energy consumption monitoring system. This provides a detailed history, as well as daily monitoring of household energy consumption, grid import/export, hour-by-hour solar generation, the level of battery charge and so on. The inverter has a useful display panel which can be read at a glance.

I really don't know how to assess performance of this equipment although it seems to me that everything is operating as it should, so I can only assume the Sungrow inverter is operating splendidly to the best of my knowledge. Certainly I have not had any failures and there has been a vast saving on my last power bill from Origin. Just the feed-in saving showing on the account was $99.00 even though there for aw hile we had many, many days of cloud cover. All in all I'm very happy we decided to install the Solar system.

When our inverter is in 'run' mode, we are very excited that we are using the sun's power! However, it seems to slip into 'derating' mode for most of the daylight hours and we cant get any satisfactory explanation or offer of inspection from Sungrow. Sungrow have suggested this is due to a high grid voltage while our supplier claims the grid voltage is within an acceptable range: 216 to 253V. An independent electrician has measured the GV across a time period and this has shown the voltage fluctuates around the high side of the range at 247V. The hardest thing is finding anyone at Sungrow who can give us some satisfactory service! Found one tech who tried to help us over the phone to reset some parameters on the inverter but we are still having the same problem. We will persevere to find a solution and hope to be only using our own power generated during the day very soon!!

Hi
I'm not sure if the solar panels are doing the job properly and If the other solar panels, originally on the roof were connected to the new ones.
The reason why I'm asking is because I had 6#190kw panels originally,=1140kw
I had 12#250 added,=3000, giving a total 0f 4140kw. The most I have gotten out the Invertor is 23.1kw. Would this be correct, and how would I now if the good solar panels that I paid extra for apposed to the medium or the cheaper ones that I opted not to buy?
I realize the sun will only be on the panels at certain times of the day,"due to cloud coverage etc", and the optimum output will only be between 11am to 3pm give or take.
So my question is, is this correct?
Otherwise I have had to ring Paul twice as my power to the house has been disconnected due to renovations and he has been very helpful on both times.
Thank you
Anthony
