Had problems with the inverter derating all the time, the electrician returned twice and after a few phone calls changed some of the settings. The unit now performs as expected.

We have a 5.4 kWp Sungrow inverter model SG5KTL-D, with Wifi, which has so far performed faultlessly, and the Wifi data logging has enabled us to closely monitor the performance of our system without any effort.

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!

A bit noisy during its early morning startup routine, particularly through the warmer months, as it's right outside our bedroom window.

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.

I'm told by Solar Australia that it is a high quality inverter. (12 260 watts phonosolar panels, all on the western side of the roof. (House faces due north but no room at the front for the system. I'm happy with performance output. This month (November) we are getting between 15 an d 20 kilowatt hours / day. Well Finn, keep up the good work. Best regards Ray

Only problem we've had is with the Wireless internet connection dropping out from time to time. I suspect this is our kids messing with our wireless hub antenna and not to do with the inverter Sungrow wireless gizmo.

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

To be honest we don't know how to compare it with anything else. We relied totally on the advice given at the time of our choice of installer 'Green and Gold'. It seems to run OK without any problems so I guess we are happy enough.

Display blanked off after 3 years. Company did not rectify the problem. Unit failed after 5 years. Although warranty is for 10 Years, Company is trying to find its way out of paying for a replacement unit. Company said the Sungrow company in China has closed.

The setup instructions for the wifi data collection was very confusing and I had to go online to search for the correct was to do this. Now that it is up and running, I don't have to bother the occupants of the granny flat (the inverter is installed in that garage) to see how much energy is being produced.

N/A Inverter has died after 4years of seemingly working ok ,fault light on,no ability to bring up a fault screen,panels seem to produce okay.What to do,phone Queensland office right4times with different person answering each time, hmm must be a call centre and they can't tell me where the New South Wales office is located,they advise to fill in online customer service request and they will get someone to call me within 1to 7 days.Does not happen so send off 2emails,a month later Candace calls me on my mobile from her mobile asking for me to send photos of Sungrow inverter and front panel ,said she will pass it on to service department.Did as requested,no reply after a week,I feel that she is in Perth and I have her contact details thanks to unseen technology.Im still within my warranty period so wait for further developments.Warning -Don't deal with Green Engineering

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!!
