Sigenergy: Premium Performance

Strengths:

Whole-home backup: Powers your entire house during outages, not just essential circuits. Run air conditioning, hot water, EV charging — everything.
Advanced AI: Learns your usage patterns, weather forecasts, and grid conditions to optimize savings automatically.
Higher power output: 12kW continuous means you can run multiple high-draw appliances simultaneously.
Superior safety: 5-layer protection system including fire suppression and thermal monitoring.
Future-proof: Expand up to 50kWh for electric vehicles, pool pumps, or whole-home independence.
Premium build quality: Engineered for 20+ year lifespan with excellent performance retention.

Trade-offs:

Higher upfront cost (20-30% more than GoodWe)
More complex installation may increase labor costs
Feature-rich may be overkill for simple backup needs

Best for:

Homeowners who want the absolute best, plan to add EVs, need whole-home backup, or prioritize long-term performance over upfront cost.

GoodWe Lynx: Proven Value

Strengths:

Exceptional value: Premium LFP battery technology at a mid-range price point. More battery capacity per dollar.
Proven reliability: Over 10 years in Australia with thousands of successful installations. Not a new, untested brand.

Modular expansion: Start small, grow later. Add capacity without replacing existing equipment.
Essential backup: Keeps critical loads running (lights, fridge, internet, security) during outages.
Established support: Solid distributor network and local service availability across Australia.

Trade-offs:

Lower continuous power (6kW vs 12kW)
Essential backup only (not whole-home)
Basic AI optimization (not weather forecasting)
Smaller maximum capacity (30kWh vs 50kWh)

Best for:

Budget-conscious homeowners who want proven, safe battery storage with excellent warranty support, without paying for premium features they may not need.
