High-Capacity Storage Solution (Tier 3 of 4)
Achieve outstanding energy tariff arbitrage with our high-capacity Sigenergy SigenStor Battery Storage System. Powered by a 10kW inverter and a massive 27kWh battery storage tower (3x stacked 9kWh modules), this package is designed for high-consumption properties, heat pump homes, or multi-EV households seeking maximum off-peak power leverage.

System Hardware Breakdown

1. Sigenergy SigenStor 10kW Hybrid Inverter (Energy Controller)
  • 10kW Power Capacity (45A AC Output): Delivers a heavy-duty 45-amp continuous AC output—providing massive capacity to run high-power domestic loads (heat pumps, cooking appliances, EV chargers, and hot tubs) simultaneously without bottlenecking or requiring 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: Heavy-duty enclosure 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 27kWh LFP Battery Storage (3x 9kWh Stacked Battery Modules)
  • Usable Capacity: Expansive 27kWh total energy capacity using ultra-safe, long-life Lithium Iron Phosphate (LiFePO4) cell technology.
  • Maximum Off-Peak Arbitrage: Holds enough low-cost energy to easily power a large 4–5 bedroom home through peak afternoon and evening rate windows without drawing from the grid.
  • Multi-Layer Thermal Protection: Built-in internal fire-extinguishing protection, cell thermal isolation, and real-time automated safety monitoring on each module.

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.

AI Smart Control (mySigen App)

  • AI Tariff Optimisation: Automatically adapts to your usage habits and tariff rates to continuously optimise battery charging and discharging cycles.
  • Smart Tariff Sync: Connects directly with dynamic off-peak tariffs (such as Intelligent Octopus Go, Octopus Flux, or E.ON Next Drive) to automatically charge the battery at the lowest rates and power your home through expensive peak periods.
  • Live Monitoring: Track battery level, home usage, grid imports, and financial savings live on your smartphone.

Estimated Annual Savings

By bulk-charging 27kWh during cheap overnight tariff windows and powering your home through all high-rate hours:
  • Estimated Bill Savings: £1,300 – £1,900+ per year (based on a high-consumption UK property utilizing smart off-peak rates year-round).
  • Peak Grid Reliance Reduction: Reduces expensive peak mains grid electricity dependency by up to 80%–92%.
