Is This the Most Advanced Home Battery System in Australia?

If you’re planning to add a battery to your solar system or want a future-proof way to run your home during outages, the Sigenergy battery is one of the most advanced options now available in Australia.
At its core is a smart, stackable lithium battery system that can grow from 5 to 48 kilowatt-hours. It works alongside a hybrid inverter, energy controller and optional EV charger to give you full control over how you generate, store and use energy.
The system is managed through the mySigen app and uses artificial intelligence to optimise battery charging, reduce electricity bills, and support virtual power plant programs. It also offers blackout protection and is built to handle both single and three phase homes.
If you’re comparing batteries like the Tesla Powerwall, the Sigenergy system offers a very different approach. It’s designed for flexibility, intelligence and full home energy integration.

Quick Pros & Cons

What We Like

  • Fully integrated system with hybrid inverter, modular battery, EV charger and energy controller
  • Scalable from 5 to 48 kWh per stack, with parallel system support for larger setups
  • Smart energy management through the mySigen app, including AI optimization and VPP readiness
  • Built-in blackout protection, off-grid capability and future-ready EV charging
  • Strong value for money given the features, safety layers and flexibility

What to Consider

  • Different to most battery-only systems, which may require more consideration during planning
  • Still a newer brand in Australia, with limited long-term performance data
  • Installer familiarity may vary, especially for those new to modular, app-managed systems. Work with an installer who has previous experience installing Sigenergy.

Is the Sigenergy Battery Right for You?

The Sigenergy system is best suited to homeowners who want more than just a simple battery. If you’re looking for a future-ready energy solution that integrates solar, storage, EV charging and backup protection into one intelligent platform, this system is a strong fit.
 
It’s especially ideal for:
  • Households planning for whole-home backup or eventual off-grid capability
  • Homeowners wanting to charge their EV with solar and explore V2H or V2G functionality
  • Buyers who value detailed energy monitoring, smart automation and long-term flexibility
  • Properties that may grow over time, with growing energy needs.
If you’re after a basic battery to store excess solar and run a few lights during an outage, this system may be more than you need. But if you want to invest in a scalable, all-in-one energy hub, Sigenergy is one of the most innovative platforms currently available in Australia.

About Sigenergy

Sigenergy is a global energy technology company founded in 2022 by Tony Xu, the former president of Huawei’s FusionSolar division. While still a newcomer to the battery market, the company has grown quickly, with over 600 employees more than 70% of whom work in research and development.
 
Sigenergy’s flagship product, the SigenStor system, reflects the company’s ambition to lead in fully integrated, intelligent home energy solutions. Its 20,000 square metre manufacturing facility is based in Shanghai’s Lin-gang innovation hub, with a solar-powered factory and advanced production systems that support a 6 GWh annual output.
 
In Australia, Sigenergy is continuing to expand its presence, with a local office based in Sydney and growing installer adoption. While the brand is still building trust, early feedback from professionals in the industry has been promising  especially in terms of product design, smart features and ease of integration.

Sigenergy Battery Model Range

The Sigenergy battery system is built around two main module sizes  5.0 kWh and 8.0 kWh  which can be stacked to create a system from 5 to 48 kWh per unit. Each stack includes the battery modules, base, and top components that connect with the Sigen Energy Controller and optional DC EV charger.
 
You can mix and match:
  • 1 to 6 battery modules per stack
  • Single-phase or three-phase hybrid inverters (from 5 kW to 30 kW)
  • Optional EV DC charging module (12.5 or 25 kW)
For larger homes or light commercial setups, multiple stacks can be installed in parallel. This modular structure allows for system growth over time, without needing to replace core components.
All models use Lithium Iron Phosphate (LiFePOâ‚„) cells and are IP66-rated for outdoor installation. The system supports both on-grid and off-grid applications and integrates directly with the mySigen app for monitoring and control.

Expanded Pros & Cons

What We Like

  • Integrated system design

Sigenergy offers a true all-in-one platform, combining the hybrid inverter, battery modules, energy controller, and EV charger into a unified system. This reduces compatibility issues and simplifies long-term upgrades.

  • Modular and scalable
With 5 kWh and 8 kWh battery modules, homeowners can start small and scale up to 48 kWh per stack or even more with parallel systems. Ideal for growing households or future energy demands.
  • Smart energy management
The mySigen app gives detailed insights down to cell voltage and temperature. It supports AI-powered energy planning, VPP participation, remote diagnostics and even EV charging coordination.
  • Future-ready features
Built-in support for DC EV charging, blackout protection, and optional V2H/V2G capabilities put Sigenergy ahead of most current home battery competitors.
