The local installer of my Solar Panels and 24kwh Sigenstor battery was helpful. A few months after installation a Sigenergy battery stalled and failed and I reported it to the installers. They referred it to Sigenergy who "rebooted" it and all seemed fine for a few days when once again the battery refused to charge / discharge. This happened… Read more
several times and each time I referred it to the installer. Sigenergy were reluctant to communicate or do anything under the warranty. The installer is continuing to try and escalate the problem. The electricity from the grid is costing me a bomb whilst Sigenergy has shut shop and isn't communication. NOT GOOD ENOUGH!!
The local installer of my Solar Panels and 24kwh Sigenstor battery was truly excellent (5 stars). A few days after installation a Sigenergy battery stalled and failed and I reported it to the installers. They referred it to Sigenergy who "rebooted"… Read more
it and all seemed fine for a few days when once again the battery refused to charge / discharge. This happened several times and each time I referred it to the very patient but increasingly exasperated installer. Sigenergy seemed reluctant to communicate or do anything to rectify the situation as per warranty. The installer finally escalated the problem to executive level and got a positive response. A new battery was "authorised". It took 8 weeks and 4 days from Installation. I now have a fully functioning and rather clever battery. I am hoping (touch wood) that I have no further problems. I note that the battery has a warranty for 10 years and it makes me wonder if the warranty will be honoured. Sigenergy has had a meteoric rise in its fortunes like many other high value consumer goods eg cars made in China. A frequent criticism is that communication, servicing and the honouring of warranties is done somewhat reluctantly. Sigenergy certainly needs to lift its game and develop efficient consumer and Installer support especially with such a good sophisticated and efficient product. One truly wonders whether it is poor Chinese management and business practices or lethargy and intransigence of Australian employees. I expected an apology from Sigenergy but all I got was the sound of crickets. Not good enough. Do I recommend Sigenergy? The battery seems very good but the Australian Company really needs to lift its game. Be cautious.
Follow-up · Further to my previous I can report that the Sigenergy battery system and the Jinko panels are performing better than expected. The Sigenergy app is very good and others have commented on its clarity. I have found it very useful in adjusting the power consumption of my Hitachi air conditioning units. I have had further contact with the installer,… Read more
Extremely disappointing Sigenergy system reliability and support I want to be clear from the outset that my installer has been extremely helpful and has continued trying to get this resolved. My frustration is not with them. My concern is with… Read more
Sigenergy, the reliability of the system, and the lack of urgency in resolving the issue.
I chose a Sigenergy system because of the brand’s reputation. I could have purchased a FoxESS system for around half the price, but I paid approximately double because I believed Sigenergy would provide a premium product backed by reliable support.
Unfortunately, within the first four months of owning the system, I have already experienced a significant problem. The system’s internal Wi-Fi scanner is not detecting any available networks, even though Wi-Fi is working normally throughout the property. The system has now been offline for around a month.
This is not a minor inconvenience. Before this issue, my energy setup meant I was not paying for electricity on a daily basis. Since the system went offline and I have been unable to use and manage it as intended with my energy plan, I have been paying for electricity each day while waiting for the problem to be resolved.
What has made this worse is the lack of clear support. I initially spent more than an hour on the phone with Sigenergy support. After that, I had to keep following up mainly by email every 3-4 days because there was no meaningful response or clear pathway forward. At the end of approximately two weeks, Sigenergy told me to contact my installer, leaving me wondering why this was not explained at the beginning. That initial delay wasted valuable time.
My installer has since been trying hard to get this resolved with Sigenergy, and I appreciate their efforts. I have asked whether someone can attend and inspect the system, but I have been told this is not necessary. Despite this, no effective remote resolution has occurred, and the system remains offline.
As a customer, I have tried to be patient, reasonable, and cooperative. I understand that technical problems can happen. What I do not understand is being left offline for weeks without a clear resolution, practical action, or an appropriate sense of urgency from a company selling a premium-priced system.
For a system that cost around double some alternatives, this has been incredibly disappointing. I chose Sigenergy because I trusted the brand’s reputation. At this stage, I feel badly let down and honestly wish I had purchased the FoxESS system instead.
A premium product should be reliable, and when something goes wrong, the support should be clear, timely, and accountable. So far, that has not been my experience. At the time of writing, the issue remains unresolved, with no clear path to a resolution.
Follow-up · After around three months, still no one has come out to inspect the system. Fortunately, after completing further system resets myself, I was finally able to reconnect it to the internet this past week. However, the connection may still not be completely right, as I am unable to complete the latest firmware update through the app, and there are… Read more
I had a 10kw single phase inverter and 6 battery stack fitted on 4/9/25, on the 13/11/25 was send the message to my phone app about the recall and replacement and how they have reduced the system to 8kw and would be replaced ASAP, now 9/4/26 and hundreds of phone calls to the installer, his suppler and Sigenergy and still HAVE NOT had the inverter… Read more
replace. Harry from Sigenergy has even told me the new green dot inverter (whatever that means) is at the suppler, but when my installer went to pick it up they knew nothing. Today i lodged a complaint with department of fair trading and have asked my installer to remove the entire system from my home as i am feed up with Sigenergy lies and me not sleeping as i worry, is tonight the night my home burns to the ground
I have a problem with the Inverter swamping my WiFi router with "BroadcastHost" UDP packets sent to the router. Using WireShark you can see that these are as frequent as 20-50 packets per second. The result is that the router performance is degraded to the point where streaming services such as Netflix Youtube and Spotify etc buffer. I just… Read more
removed the WiFi dongle from the inverter as a temporary fix for the problem. The BroadcastHost UDP packet flood has stopped, but of course I can no longer view my inverter data.
Various online forums mention this UDP flood/torrent behaviour and SigEnergy responded with "this is normal for the inverter". I find that very hard to believe as it is the only device in the home exhibiting such behaviour. FIX IT!
BEWARE FUTURE BUYERS !!! Some of the single phase inverters have been recalled across Australia . Multiple units have below standard wiring plugs that have melted and represent a fire hazard . A problem that was quickly fixed (allegedly) As new installed have powered forward and I can buy a new one with correct inverter plug online in several… Read more
places . No attempt has been made to rectify the problem . Although some have been replaced there's still hundreds out there that have been waiting to hear anything from as long ago as late October . Meanwhile all affected inverters have been restricted in feed back kw.
And here's where it gets really infuriating. There's no way to contact them . All you can do is lodge a so called ticket . In turn they may or may not get back to you . I've lodged a few and they come up as processing only to disappear into finished without you ever haven spoken to anyone. My honest opinion . It's an awesome product and worked well before they cut me down . But like so many new adopters we've been severely let down . Service is non-existing . A shame because they market themselves as a premium product but can't back it up with service and contactabillty .
Trust shattered !
Do not buy this product The program that runs the system limits the charge back to the grid. SAPN allows my system to send 9.6 back to the grid but Sigenergy restrict me to 4.6. No support No warranty service You just can’t get to speak to anyone to get the system fixed. UPDADATE 4 months since installation and the system still doesn’t work. I want my money back. !

Two weeks ago I did a review regarding faulty plug warranty issue ,sigenergy asked me to contact them and they would do something , nothing yet It’s been months since this matter was made public as an issue Show details
Prime Solar energy installed this Sigenergy 40kWh battery system, I am extremely satisfied with the installation and the workmanship of the Technician/Prime Solar Energy Staff. Saying this I am still getting use to the Mobile App. and discovering lot of things So far so good and it is working well...I highly recommend Sigenergy Show details
Sigenergy 8kw inverter and 24kw battery Have had solar power for the past 8 years, 6.6kw system and no battery. Inverter was not a hybrid type, only 5kw and unless ac coupled to a battery would not be a very effective or efficient addition, plus with the 5kw inverter not going to generate enough to fill a bigger battery, especially in the winter… Read more
months.
Since the government rebate programme, the field is awash with suppliers and battery options, it can get confusing to most of us.
Started out with multiple quotes all offering different versions and options of the same theme, then decided to go with a local to my area supplier after talking to friends who had opted for 3rd party and sub contract 3rd party suppliers from out of town and did not have the best experiences. My existing system was 6.6kw generation into 5kw inverter. After review of my consumption patterns and configuration, decided that a 24kw battery was the sweet spot. The supplier recommended upgrade to 8kw inverter with 3 MPPT inputs so that additional panels could be added to boost output.
The new supplier to the market, Sigenergy was recommended as the best battery / inverter combination along with an additional 8 Jinko Tiger neo 52 cell 510 panels (Same as the 475w version but new panels) The panels were also recommended because of performance in lower light conditions and near 24% efficiency.
One of my main criteria for a battery was ability to be installed outside (did not want it in my carport) and have strong fire protection and extinguisher built in. The other criteria were the depth of discharge of the battery and rated cycle life, plus getting the benefits of it being DC coupled which I was advised was the best way to go. The good thing about the Lipo (Lithium-ion Phosphate) batteries is that they are not prone to runaway fires so that is a tick (most batteries are lipo)
In WA, the authorities have just approved inverters on single phase up to 10kw, and because I was recommended to keep my original 2 strings of panels (6.6kw) and add 8 x 510 panels, was recommended for the 3 MPPT input 8 kw Sigenergy converter into the Sigenergy 24kw battery (3 x 8kw modules)
The installation was seamless, the integration of the original panels into the new inverter was no problem, all wiring and switching upgraded. The sigenergy batteries are modular (like most manufacturers) and the whole stack, including the batteries was about as neat as you could get. I have seen many pictures of people concerned about their installations and some of the pictures look very untidy, but could not fault how the Sigenergy system gets put together. Sigenergy had a bit of an issue with overheating of some of the AC connectors causing the batteries to shut down, throttle back and posed a potential fire risk, but they have been proactive and will diagnose and replace inverters affected. It seems from what I can gather that the number of problems identified is small compared to the number of installs, and was identified as installation error in a lot of instances, which has been rectified by improvement to the inverter design and AC connector. My installer told me that the instructions for installing Sigenergy inverters and batteries are very explicit and must be followed and not following the correct procedure could be an issue.
Since installing the upgraded 10.6kw of roof panels into 8kw inverter and 24kw battery, the power generation has been excellent. I can be using 6kw into the house and still generating enough power to charge the battery. At times I have seen 10kw coming out of the solar panels and the battery is charged by around 10am at this time of the year. The Sigenergy system manages the hierarchy and flow of power very well – I left the initial set up to the installer and have had no problems.
The app that is supplied to run the whole power generation system and provide real time power monitoring and status is one of the best I have seen, there is virtually nothing it does not tell you, including full performance monitoring of the solar panels strings so that you can easily see the outputs and determine any problems with the system. I have seen some people say that the app is only available by paying a subscription, but I pay no subscription, it came with the package. Instead of using a WIFI extender to connect the inverter (and the smart sigen meter in the meter box) it was connected directly to the router via ethernet which gives it very stable connection.
The hierarchy of power generation is set in the app, and the supplier should assist with these setting changes as you do not want to be playing around with and upsetting the balance. My system is set to power source from (1) Solar, (2) Battery and (3) Grid. I do not run off peak 3 tiered tariffs and in WA we do not have multiple power suppliers.
Some installers suggested getting a 40kw battery and topping it up during off peak tariff rates which they say is a good thing in the winter months. The Sigenergy management system can run off peak top up of the battery but that is not a dynamic I have explored yet.
Since installing the Sigenergy system 2 months ago, we have not had to pay a power bill. The battery gets us through the night and we now only pay fixed charges. That is as much about selecting the optimal size system for your consumption as much as it is about the battery supplier and brand, but Sigenergy system has been a very big improvement to our energy management and the quality of the system is very, very good. Based on our experience, I would recommend that you include Sigenergy battery system into your quotations - Sigenergy are not the cheapest price option, we started with Alpha and Fox and other suppliers and ended up with Sigenergy - they have only been in the Australian marketplace since early 2024 and we had some reservations about that, but based on the Suppliers experience and recommendation, we went with Sigenergy, no regrets so far, has exceeded our expectations.
PROS: Very good build quality equipment (both inverter and battery); Warranty is good, 10 years on both inverter and Battery (rated by cycles / % remaining after 10 years); IP66 rated – can be installed outdoors; No noise, inverter very quiet, outside anyway, but you could install near a bedroom and not notice; Modular design, interlocks, no messy cables, ducts etc.; Depth of discharge capability is rated at 100% (but is set at around 96% so it does not bottom out); Can easily be added to later – additional battery very easy to add; Has full blackout capability and EV charging options (for additional cost); LIPO batteries, much reduced potential fire risk; Multiple layers of fire protection built in, along with internal fire extinguishers in each module;
CONS: Have not encountered any cons, Supplier / installer was excellent, great attention to detail and the equipment meets or exceeds expectation.
We are happy with the product that we chose. Recommend it anyone looking at installing batteries Show details
Every time the internet drops out reconnecting this thing is a nightmare. Currently I can not get it back on line and have been offline for two weeks. No support no help. Meanwhile the $20k I paid is wasted while I continue to pay my electricity company. I am so over it and so upset. I went into debt thinking what I would be saving would pay for… Read more
the system. Please be aware this system is not user friendly and is not intuitive and will not save you thousands.
I recently installed the Sigenergy single-phase 48kWh battery system, configured with six 8kWh modules, and I’m genuinely impressed with what this setup offers right out of the box. Here is timelapse for my install: https://youtu.be/PKlSBopGIv0. The modular design is one of its biggest strengths each 8kWh module stacks neatly, making it easy to… Read more
scale up or down as energy needs change. There are 5kWh modules available too. The internal connections keep the installation tidy and eliminate the clutter of external wiring, which is a big plus for both aesthetics and safety. Here is video before the install. You may wish to see, the packaging and my rationale for choosing the battery installation and Sigenergy in particular. https://youtu.be/iTL0KvOOHR8
From a technical standpoint, the battery uses Lithium Iron Phosphate (LiFePO4) chemistry, known for its stability, safety, and long lifespan. This gives real confidence in the system’s durability and performance over the long term. The 48kWh total capacity is substantial, making it ideal for homes or small businesses looking for robust backup power or to maximise their solar self-consumption.
The system also comes with advanced smart management features. The mySigen app allows for detailed monitoring and control, right down to individual cell voltages and temperatures. The AI-driven energy management (if you can trust it and if this is your thing) system is designed to optimize charging and discharging, helping users get the most out of their stored energy with minimal effort.
Another standout feature is the future-ready design. The battery system can easily integrate with an electric vehicle charger (note here - you can't use all 6 modules if you plan to get a DC charger, have to go with 5), including support for bidirectional charging. This means it’s well-prepared for evolving energy needs and new technologies.
Overall, the Sigenergy 48kWh battery system offers a powerful, flexible, and smart energy storage solution. Its modularity, advanced safety features, and intelligent management tools make it a compelling choice for anyone looking to enhance their energy independence and sustainability. I’m excited to see how it performs as part of my home energy system. If you want to see the final video with the installer, you can find it here: https://youtu.be/0-X4KuPHNo0

Know better, choose better.
The EV charger has not worked since it was installed a week ago and nobody knows what the issue is. They have now escalated the issue to the R&D department. If it isn't obvious what this means, our installation site has become a beta testing facility to find and correct software and system bugs. We are now forced to charge our EV outside of the house after having paid over $6k for the EV charger alone. Show details
Sigenstor Energy System – I recently had Perth Solar Group install my SigenStor Energy System. 13.2kWh of new Panels and 13kWh battery system. They system has been amazing and is a game changer. Really pleased with the modular battery option with expandable modules. My power bills have come down by almost 70% compared to the previous year, which only had a 5kW solar… Read more
system. I can utilise the Aircon all day without having to worry about power.
The SigenStor system has allowed us to go a few nights without having to draw power from the Grid as all the consumption for night time came from the Battery.
The Mobile App is excellent. User Friendly and easy to use.
Attached Photo, you can see the unit consumption for January 2025, 277kWh consumed from Grid,~$80.00. Total Used with Aircon Running all Day: 1921kWh ~ $551.00 saved.
Careful!! Hidden stuff!! – It is a trap!! They brag about AI and AI and AI and they make it hidden in the FAQs that they "might" offer this feature for a subscription!! Are they waiting to sell more? I hate hidden stuff that applies to the adopters who trusted the such a new brand!! Why would I pay more to get a feature that I would pay for in the future??!!
Lose the power companies – On August 3, 2024 Thomson Energy installed the Sigenergy system. (Thomson Energy review here https://www.productreview.com.au/listings/thomson-energy) September 10, I went off-grid. The critical failure of my old system on October 26 2023 put me back on the electricity grid without the benefit of solar panels. What a rip-off the power companies… Read more
have engineered at consumers' expense. I also discovered that my very energy efficient house cost (then) around $400 a quarter in power bills without the benefit of solar.
In June 2024 my electricity retailer advised the privilege of remaining on the grid increased to $2+ a day, the tariff for grid electricity 'generously' dropped to $0.467/kWh and I'd get 4c/kWh for the power feed into the grid. So I was paying them $60 a month for the privilege of giving them very cheap electricity while they're shedding renewable power because it 'overloads the grid'.
The new system cost $16,205 installed with 16kWh of battery power and has a ten year guarantee. I already had the panels. The numbers add up and my sparkies sorted the wiring so I can run the house off a generator if I need to. Unlikely because the batteries charge from the panels in 5/8 cloud as illustrated in the screenshot.
There's an app that keeps track of the household energy use and literally has all the bells and whistles you could ever want. There's an option for managing the system if you have done a deal to on-sell electricity. I think you need a SmartMeter for this so check first!
With a product like this why would anyone stay on the electricity grid if they didn't have to?
Edit - January 3, 2026
Update - with the Federal Government subsidy on batteries there is even less reason to stay on the grid. My Sigenergy system has been completely - I mean 100% - reliable and now that I've got a little better at running it, I've sorted it so I can plug a cheapo generator into the circuit board and it charges the batteries as well as runs the house if necessary. I live rural/remote with no mobile phone service (tank water and septic too!) so I occasionally have to reset the system to get the monitoring software back but the battery never fails.
There's also the software and capacity for an EV charging port.
Finally, the arithmetic stacks up even without the subsidy. The system comes with a 10 year guarantee backed by my local Thomson Energy people. If I was on the grid, $400 a quarter x 4 = $1600 annually. $16k over ten years and the cost of electricity is never going to go down. I reckon the battery will outlive the ten year mark.
The electricity industry is feeding you nonsense about reliability. Remember it's privatised. Customer service isn't the same as shareholder service.
