Sigenergy SigenStor 16kWh Solar Battery Storage Performance and Capacity

The Sigenergy SigenStor 16kWh solar battery storage system is formed by stacking compatible high-voltage LiFePO4 modules (typically two 8 kWh units) under a SigenStor Energy Controller to deliver approximately 15.6 kWh of fully usable energy at 100 percent depth of discharge. Continuous charge and discharge power scales with the number of modules and controller, providing robust support for household loads, while short-duration peak power handles higher demand. The system operates across a high-voltage range of 300 to 900 V depending on single-phase or three-phase configuration.

Round-trip efficiency benefits from large-capacity LiFePO4 cells and AI-optimised management, maximising solar self-consumption with minimal losses. Individual modules measure approximately 767 x 270 x 260-265 mm, with total system weight depending on the exact module combination and controller. Up to six modules can be stacked per Energy Controller, and multiple controllers can be paralleled for further expansion beyond 16 kWh.

Cell technology is lithium iron phosphate with high cycle life rated up to 10,000 cycles to 60 percent state of health under standard conditions. Operating temperature spans minus 20 to plus 55 degrees Celsius with natural convection cooling, ensuring reliable year-round performance across Australian climates.

Sigenergy SigenStor 16kWh Solar Battery Storage Compatibility Safety and Durability

Sigenergy SigenStor 16kWh solar battery storage The system requires a Sigenergy SigenStor Energy Controller for operation and is fully compatible with the SigenStor hybrid ecosystem, including single-phase and three-phase controllers. Communication and monitoring are handled via the mySigen app with real-time status, AI energy planning and remote diagnostics. Multi-layer safety protection includes cell-level safeguards, system-level monitoring and rapid response features.

Enclosure protection is rated IP66 on the battery modules, providing excellent weather-seal protection against dust and water for true indoor or outdoor installation without additional housing. The robust design supports quick-connect stacking where modules auto-connect for power and communication, reducing installation time. Certifications include IEC/EN 62619, UN38.3, IEC/EN 63056 and related standards, confirming high safety and transport compliance.

Pre-shipment inspection checks verify capacity, communication integrity and physical condition before dispatch. Every system is factory-tested so customers receive verified performance data. The stable LiFePO4 chemistry combined with multi-layer protection and high ingress rating minimises weather-related degradation, supporting the full ten-year product warranty under normal operating conditions.
