Who Is Sigenergy?
Sigenergy is a new energy company that started in 2022. It is based in China. Even though the brand is new, the people behind it are not. Many of the engineers used to work at major tech companies, including Huawei, BYD, and CATL. These companies are well-known in the solar and battery industries. While the Sigenergy name is new, the team has years of experience.
Sigenergy focuses on smart battery systems for homes and businesses. Their main product is called the SigenStor. It combines:
- Solar inverter.
- Battery.
- Energy management.
All in one unit.
Most other brands sell these parts separately. By putting them all together, Sigenergy says the system runs more smoothly. It also takes up less space.
The company is already selling in over 20 countries. In Australia, more installers are starting to offer it, especially in NSW and Victoria. Sigenergy also has a local support team in Australia. That’s important if you ever need help, repairs, or replacement parts.
Their products meet all major Australian safety standards. The Clean Energy Council approves them and follow AS/NZS 4777 rules. This means they are safe to install and use in Australian homes.
Sigenergy is still building its reputation, but it has already made a name for itself. The design is sleek, the system is intelligent, and everything works together in one unit. For many people, that makes it worth a closer look.

Sigenergy SigenStor Key Features & Performance
The Sigenergy SigenStor is an all-in-one energy system. It includes five key parts:
- Inverter
- Battery
- EV charger
- Energy controller
- Energy management software
Sigenergy designs all of these parts to work together as a single, intelligent system.
Each battery unit holds 8 kWh of energy. You can stack up to 6 units per system, giving you a total of 48 kWh of storage.
This is more than enough for most homes, and you can start small and add more later if needed. This type of setup is called modular, meaning you can scale up as your energy needs increase. The battery blocks stack up like Lego toy building blocks.
The battery uses LFP (lithium iron phosphate) chemistry. This is known for being safe, stable, and long-lasting.
The SigenStor system also features a built-in inverter, eliminating the need for a separate one. The inverter supports both solar panels and battery charging. It also works with the grid, so you can sell power back or use stored energy when needed.
Here are some other key features that matter:
- Fast Installation: Since all parts are designed to work together, installers report that it’s quicker and easier to set up than when mixing brands.
- Smart Software: The Sigenergy app enables you to track the energy your system produces, stores, and uses in real-time.
- AI-Driven Controls: The system learns your energy habits and weather patterns to plan when to charge or discharge the battery.
- Blackout Protection: If the power goes out, the system can run your home off the battery. You can choose which appliances stay on.
- AC or DC Coupling: It supports both types of solar systems, making it compatible with most homes.
- EV Charger Option: You can add a Sigenergy EV charger that works with the system and uses stored energy to charge your car.
- True Three-phase Backup: For three-phase homes, this battery is a game-changer because it can back up all three phases simultaneously. Not every solar energy system can.
In terms of performance, the system runs at a high efficiency, with up to 97.5% round-trip efficiency. This means you retain most of the power you store, with minimal loss.
For individuals seeking a clean, innovative, and expandable battery system, Sigenergy offers strong technical features. It works well with modern solar setups and is compatible with both new and retrofit installations.
