Introduction
When comparing solar batteries in Australia, two names now come up more often than ever: Sungrow and Sigenergy.
Sungrow has been in Australia for over a decade, building a reputation for reliable, scalable, and affordable battery storage. Sigenergy, on the other hand, is a newcomer but one making big waves with its SigenStor system, which integrates modular batteries, hybrid inverters, EV charging, and AI-driven energy management into one platform.
Homeowners often ask questions like: “Is Sigenergy better than Sungrow?” or “Which battery brand should I trust more?”. The answer depends on what you value most: proven track record and simplicity (Sungrow) or cutting-edge features and future readiness (Sigenergy).

Head-to-Head Comparison
1. Performance & Scalability
- Sungrow: Can scale to one of the largest capacities in the market (102.4 kWh), but modules are floor-mounted only.
- Sigenergy: Scales to 48 kWh per stack, with parallel options for even larger setups. Offers more flexibility with wall or floor mounting.
- Verdict: Both are highly scalable, but Sigenergy offers more flexibility in design and installation.
2. Backup & Compatibility
- Sungrow: Provides backup only when paired with Sungrow hybrid inverters. Best suited for self-use systems rather than full off-grid setups.
- Sigenergy: Designed for whole-home or partial backup, with optional off-grid capability built in.
- Verdict: Sigenergy has a clear edge here, especially for blackout protection and energy independence.
3. App & Smart Features
- Sungrow: iSolarCloud app is functional but basic, with limited automation or time-of-use logic.
- Sigenergy: mySigen app provides advanced insights, AI optimisation, and even coordinates EV charging.
- Verdict: Sigenergy leads in smart features, ideal for tech-savvy households.
4. Brand Presence & Support
- Sungrow: 10+ years in Australia, wide installer network, strong local service team. Proven reliability.
- Sigenergy: New brand (since 2022), Australian office established, installer adoption growing but still maturing.
- Verdict: Sungrow has the stronger track record; Sigenergy is promising but still building trust.
5. Value for Money
- Sungrow: A safe, mid-market choice with competitive pricing and proven performance.
- Sigenergy: Priced fairly considering its features (AI, EV charger, modular system), often compared to premium systems like Tesla but at lower cost.
- Verdict: If you value future features, Sigenergy delivers exceptional value. If you want proven reliability, Sungrow is safer.
Which Should You Choose?

- You want advanced smart features and detailed energy management.
- You’re planning for EV charging, V2H/V2G, or future off-grid capability.
- You’re comfortable being an early adopter of a new but promising brand.
Final Verdict: Sungrow vs Sigenergy Batteries in 2025
Both Sungrow and Sigenergy sit within our recommended shortlist of batteries for Australian homes, but they appeal to very different types of buyers.
- Sungrow is the safer choice for most homeowners: proven reliability, long-standing presence in Australia, and strong installer support. It’s the brand to choose if you want confidence, simplicity, and value.
- Sigenergy is the innovative choice for forward-looking households: cutting-edge features, AI-driven energy control, and integrated EV charging make it one of the most advanced platforms on the market today.
If your priority is peace of mind and proven performance, go with Sungrow. If your priority is innovation, smart features, and future readiness, Sigenergy may be worth the leap.
