When you hear the word recall, it’s natural to worry about things such as smoke, fire, and warning signs. You might also expect long phone calls and unclear answers, all while your power bills keep rising.
PSC Energy knows this situation can be stressful. We’re here to explain the Sigenergy recall, share our experience, and give you simple steps to follow if you’re affected.
Key takeaways
- The recall covers Sigenergy single-phase 8 kW, 10 kW, and 12 kW inverter (Energy Controller) units with a quick-connect AC plug design.
- The recall notice says the AC plugs may overheat and become damaged, posing a fire risk. The notice states that incidents occurred and that no property damage or injuries have been reported.
- The recall notice lists a sales window in Australia of units sold from 4 March 2025 to late November.
- Sigenergy uses a firmware update as a temporary risk control. The recall notice says the update is able to temporarily reduce AC output under sustained full load to prevent overheating.
- Sigenergy provides a free replacement with an updated AC plug and an additional 2-year warranty.
Let’s look at which Sigenergy products were recalled and why these models are in the spotlight.
Why Did the Sigenergy Inverter Recall Happen?
The recall notice states the reason in plain words. The AC plugs may overheat and become damaged. The notice says this poses a fire risk.
The hazard is also stated in plain English. A fire can cause property damage, serious injury, or death. The notice says incidents have occurred. The notice says no property damage, injuries, or death have been reported.
We understand this language is strong, but simple and straightforward information is important during a recall.

What Does Single-phase Mean?
Many homes in NSW run on single-phase power. A single-phase connection means your home uses one supply line from the street. Single-phase supports household loads like lighting, power points, fridges, and Wi-Fi.
Larger and newer homes often use three-phase power. Three-phase connections use three supply lines from the street. Three-phase supports higher-demand loads, such as ducted air conditioning or pool pumps.
This recall focuses on single-phase models in the 8 kW, 10 kW, and 12 kW Energy Controller (inverter) sizes.
Who Should Pay Attention to the Sigenergy Battery Recall?
Sigenergy already contacted the affected owners.
If Sigenergy contacted you about the recall, this article applies to you. Customers received a notification via the mySigen app if their product was affected by the recall.
You might also want to pay attention if you planned to install one of these units and you now feel unsure.
Here’s what you should do next: Stay calm and follow these easy steps.
- Keep your system connected to the internet. The recall notice says this is necessary to receive a firmware update. This update allows Sigenergy to proactively monitor and maintain each system. Check that your internet connection stays stable.
- Check the mySigen app regularly. If there are additional updates or instructions, you will receive notifications through the app.
- Do not try to fix anything yourself. Do not open covers or touch wiring. If you think there is a problem, contact your installer. Your installer can safely inspect and replace equipment.
- Keep using your system as usual unless your installer tells you otherwise. The recall includes a software control and a hardware replacement pathway. You do not need to shut the system down unless you receive direct instructions.

What PSC Energy Saw When the Sigenergy Recall Was Announced
PSC Energy installed just under 500 of these single-phase units in the affected size range. That number matters because it gives us real field data across a large fleet.
We saw a failure rate of less than 2%. While that seems low, it’s still important when you have a large number of systems, especially as Australia’s largest Sigenergy installer.
A solar inverter runs every day while your solar or battery is working. It needs to last a long time. The SigenStor stack also carries long warranties, so owners expect stability.
We know an inverter failure isn’t just a statistic. It affects your savings, can reduce your solar generation, and may lead to confusing alerts or error messages. It also means spending time finding answers and arranging repairs.
The recall notice points to the AC plug. In the failure cases we saw, the problem showed up at the AC plug connection point.
What the Recall Announcement Triggered Inside PSC Energy
The recall announcement was a turning point for us. It led to a quick internal checklist and a clear question.
We treated the announcement as a test of patience, systems, and trust. We also treated it as a test of the relationship we built with customers over the period we installed these inverters.
We didn’t treat this as routine service. Instead, we saw it as a situation that required structure, quick decisions, and clear communication.

Sigenergy Blames Installers for the Product Recall
Sigenergy has linked the issue to installation errors in public statements to regulators. We understand why a manufacturer would focus on installation quality. Good installation matters.
That’s why PSC Energy handles everything in-house, from your first consultation to warranty support. This approach helps us keep installation quality high and consistent.
However, we disagree with any framing that treats installation error as the only factor.
We install a lot of systems, and we follow the manufacturer’s instructions closely. We take pride in our work.
When we notice the same issue at different sites, we also think about how well the system is designed. Good design lowers the risk of connection problems and works better in actual conditions. Electricians often work in tight spaces and tough weather, so products need to be built for that.

Risk Controls Sigenergy Used
Sigenergy used a temporary software control while replacement logistics scaled up.
The recall notice told owners to keep the system connected to the internet so it can receive a firmware update. The firmware update enables Sigenergy to proactively update and monitor each system.
This update temporarily reduced AC output when the product operates at sustained full load. This control aims to prevent the AC plug from overheating and becoming damaged.
If your system is affected, you may notice some changes in performance. For example, you might see lower output during times of high demand. You could also get new app messages or see changes in your system graphs, which might be confusing.
You don’t need to fix this yourself or search through your settings. This safety measure is only temporary while replacements are being arranged.

What PSC Energy Did at the Time of the Recall Announcement
Every recall reaches a key moment. For us, this recall had a clear turning point.
PSC Energy ran a quarantine day on 19 November 2025. We stopped all outbound single-phase stock that day. We treated that date as a full stop for that workflow while the recall process became clear.
After that date, all new installations used updated connection hardware. Systems installed before then still need to be fixed through the replacement program.
Why the Recall Replaced the Whole Inverter Instead of the AC Terminal
If it were only the AC terminal that was the failure point of the inverter, why didn’t Sigenergy have installers swap out the AC terminal instead of swapping out the whole inverter, as has been asked?
Sigenergy wanted to make sure the AC terminal was installed per the manufacturer’s specifications.
Installing a new AC terminal requires removing the front cover and many components from the Sigenergy inverter or energy controller.
Installing these on-site may not have been the most sterile environment, and it could have caused future problems or reliability issues with the inverter modified on-site.
Instead, Sigenergy chose to completely remove every inverter from the site, replace the terminal in a controlled environment, and have that inverter go out and get a second life as a warranty inverter.
Most people who are getting replacement inverters from Sigenergy will find that their inverter is refurbished.
It has gone through Sigenergy’s internal processes and procedures to ensure it is a high-performing, electrically sound apparatus.
Sigenergy has generously extended the warranty on every inverter by 2 years, meaning your inverter went from a 10-year warranty to a 12-year warranty.
We believe Sigenergy made the right choice for installers like PSC. To keep things simple and consistent for our customers, we replaced every inverter as needed.
