System Hardware Breakdown

1. Sigenergy SigenStor 6kW Hybrid Inverter (Energy Controller)
  • 6kW Power Capacity (32A AC Output): Delivers a full 32-amp continuous AC output—providing enough power to run heavy household appliances (ovens, heat pumps, EV chargers) simultaneously without bottlenecking or relying on peak grid import.
  • Modular Stackable Design: Components stack seamlessly together with concealed internal connections—eliminating external cabling runs, isolator clutter, and pipework.
  • IP66 All-Weather Rating: Engineered for flexible indoor or outdoor installation in all weather conditions.
  • Modular Expansion: Integrated provisions allow easy addition of extra battery modules straight onto the stack as your energy needs grow.
2. Sigenergy 9kWh LFP Battery Storage
  • Usable Capacity: 9kWh energy capacity using ultra-safe, long-life Lithium Iron Phosphate (LiFePO4) cells.
  • Fast Charge/Discharge Rate: Swiftly charges during short off-peak grid windows to power your home through expensive peak hours.
  • Multi-Layer Thermal Protection: Built-in internal fire-extinguishing protection, cell thermal isolation, and real-time automated safety monitoring.

Optional System Add-Ons Available

  • Sigenergy 12kW DC Bi-Directional EV Charger: Stacks directly onto the SigenStor tower for ultra-fast DC vehicle charging straight from your battery array, complete with Vehicle-to-Home (V2H) and Vehicle-to-Grid (V2G) bi-directional capability.
  • Sigenergy Sigen Gateway (Whole-Home Backup Power): Provides seamless micro-second automatic switchover to keep your home fully powered during grid power cuts and outages.
