If you’re considering installing a solar battery in 2025, this article will help you determine if the SigenStor is a suitable option for your home.
What is the Sigenergy SigenStor?
The Sigenergy SigenStor is a complete solar energy system. It includes a battery, a hybrid inverter, and an optional electric vehicle charger. It’s designed for use with solar panels to generate your own energy and store it for later use.
It can be installed in homes with either single-phase or three-phase power. The SigenStor works with both.
You can add the system to most existing solar setups. It means you don’t have to start from scratch if you already have solar panels on your roof. You can also install it as a complete energy system with new panels and an inverter. Either way, this gives you some flexibility.
You will install the SigenStor as either DC-coupled or AC-coupled. These terms describe how the battery connects to the rest of your solar system.
DC-coupled means the solar panels send energy straight to the battery. This is more efficient. Less energy is lost when the power generated by your panels is transferred to your battery. DC-coupling is most efficient when installing a complete, new system.
AC-coupled means the solar panels send energy directly to an inverter. Then, the power gets sent to your battery. This setup is typically more suitable for homes that already have solar panels and want to add a battery.
The SigenStor also comes with smart energy software. This software uses artificial intelligence (AI) to manage your energy. It helps you save money by knowing when to charge or discharge the battery. It monitors factors such as your energy usage, the weather, and electricity prices.
The whole system is designed to help you lower your bills, utilise more of your solar energy, and keep your home running during power outages.

Pros of the Sigenergy SigenStor
The SigenStor has many strong features. It provides flexibility, intelligent energy control, and reliable backup support. Here are the main benefits.
1. It’s Modular and Scalable. The SigenStor lets you start small and grow over time. Each battery module stores 8 kilowatt-hours (kWh) of energy. You can stack up to six battery modules in one tower. That gives you up to 48 kWh in one SigenStor unit. If you need even more, you can add more towers.
This is helpful if your energy use might grow. For example, if you plan to purchase an electric car or add more appliances later, you can add more storage when needed.
Each battery module has its own energy management system built into it. This means the system continues to function well as you add more storage. You won’t lose performance as your system grows.
2. It Works for Single-Phase and Three-Phase Homes. Some homes in Australia use single-phase power. Others, especially larger homes or ones with high energy needs, use three-phase power. Many batteries only back up one phase of the power supply. That means they only power part of your home during a blackout.
The SigenStor can back up all three phases. This means it can power your whole home, not just one part. If your home has three-phase power and you require full backup, this feature is crucial.
3. You Can Add a DC EV Charger. If you drive an electric car, this is a valuable feature. The SigenStor has an optional EV charger that can be added to the system. You can plug your car into the charger and use your solar power to charge your vehicle.
You can choose between an AC or a DC charger. The DC charger is faster and more efficient. Some electric cars also support bidirectional charging. This means your vehicle can send power back into your home or battery. If your car supports this feature, the SigenStor can take advantage of it.
4. It’s Very Efficient When DC-Coupled. When the SigenStor is installed as a DC-coupled system, it means your solar panels send power straight to your battery without extra steps. You charge your battery faster, and you lose less power as heat in the process.
The SigenStor has up to 98% round-trip efficiency when DC-coupled. This is very high. It means you keep more of the energy your panels make, and that saves you money over time.
5. It Has Smart Monitoring and AI Features. The SigenStor comes with an app called mySigen. The app allows you to view the power generated by your panels, the amount you are using, and the amount stored in your battery.
But it does more than show numbers. The app uses AI (artificial intelligence) to help you save energy. It learns how and when you use power in your home. It checks weather forecasts and electricity prices. Then, it makes smart choices about when to charge or discharge your battery. These choices help you use more solar power and save money.
The AI is built using ChatGPT-4 technology. It improves over time as it learns from your habits.
6. It’s Safe and Designed to Last. The battery uses lithium iron phosphate (LFP) chemistry. This is one of the safest types of battery chemistry. It handles heat better than regular lithium-ion batteries and lasts longer.
The SigenStor also has several safety features:
- Surge protection.
- Short-circuit protection.
- Thermal sensors and temperature control.
- An internal fire extinguisher.
Most batteries do not include an internal fire extinguisher. This shows that safety was a high priority in the design.
8. It’s Rebate-Friendly. You can get rebates when you install a SigenStor. In New South Wales, you can apply for the NSW battery rebate. There is also a new federal battery rebate. These rebates can save you thousands of dollars.
Your rebate amount depends on the amount of battery storage you install. The more kilowatt-hours you install, the more rebate you receive. This makes the system more affordable for many families and significantly reduces the payback period.

Cons of the Sigenergy SigenStor
No solar battery is perfect. The SigenStor has a lot to offer, but there are also some factors to consider before making a decision. Here are the main downsides.
1. There’s a Central Point of Failure. The SigenStor features a hybrid inverter located at the top of the battery tower. This inverter is like the brain of the system. If it fails, the entire system stops functioning until it is replaced.
The good news is that the inverter can be swapped out fairly easily. But it is still a single point of failure. It’s a much bigger problem with other batteries in its class that aren’t modular.
2. The Brand Is Still New. Sigenergy is a young company. They started in 2022. They are growing rapidly and have made a strong impression in the industry, but they do not have a long history yet.
Some people feel more comfortable choosing a brand with a longer track record. Companies like Tesla and Enphase have been around longer and have more data to demonstrate the longevity of their systems over time.
SigenStor offers a competitive warranty and has offices in Australia, but its claims process is largely untested.
3. The App Is Still Maturing. The mySigen app is powerful and features many intelligent capabilities, but it is still relatively new. As a result, some users may encounter bugs or missing features early on. The company updates the app often and adds improvements.
4. The EV Charger Costs Extra. The electric vehicle charger is not included in the base SigenStor system. It is an extra piece that you pay for if you want it. The cost depends on whether you choose an AC or DC charger.
If you don’t have an electric vehicle yet, this may not be a concern. But if you plan to charge your car using your solar battery, you will need to factor in the extra cost.
5. SigenStor Internet Connectivity Issues
SigenStor batteries do not include built-in 4G connectivity. They rely entirely on your home’s internet connection.
- If you have a home Wi-Fi connection, there is no issue.
- If you don’t, you’ll need to purchase an external dongle and a 2-year data plan, which costs approximately $250.
- If the dongle isn’t renewed or the system stays offline for more than 90 days, the battery will shut off.
- A simple hotspot connection for a few hours will restore it, but you must remember to do this every 90 days.
- The warranty remains valid, but the battery won’t work until it reconnects.
This can be a significant inconvenience for remote homes or those without reliable internet access.
