Sigenergy Solar and Battery

Sigenergy SigenStor 8kW Solar & 36kWh Battery Package (Supply & Installation)

System Hardware Breakdown

1. Sigenergy SigenStor 12kW Hybrid Inverter (Energy Controller)

• 12kW Power Capacity (55A AC Output): Delivers a massive 55-amp continuous AC output—providing unmatched throughput to run multiple high-power domestic loads (heat pumps, multiple EV chargers, electric hobs, and home saunas) simultaneously without grid assistance or bottlenecking.
• Modular Stackable Design: Components stack seamlessly together with concealed internal connections—eliminating external cabling runs, isolator clutter, and pipework for an ultra-clean architectural finish.
• IP66 All-Weather Rating: Heavy-duty enclosure engineered for flexible indoor plant room or direct 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 36kWh LFP Battery Storage (4x 9kWh Stacked Battery Modules)

• Usable Capacity: Unmatched 36kWh total energy capacity using ultra-safe, long-life Lithium Iron Phosphate (LiFePO4) cell technology.
• Maximum Off-Peak Arbitrage: Holds enough low-cost energy to run a large 5–6+ bedroom home through multiple days of bad weather or peak energy rate periods without drawing from the mains grid.
• Multi-Layer Thermal Protection: Built-in internal fire-extinguishing protection, cell thermal isolation, and real-time automated safety monitoring on each module.

3. 8kW Premium Solar Array (16x LONGi 505W EcoLife All-Black Panels)

• High-Yield Output: 16x premium LONGi 505W panels providing over 8kW total peak array power.
• Sleek All-Black Design: Dark cells and black frames deliver a subtle, high-end appearance across large roof expanses.
• N-Type Back-Contact Technology: Superior efficiency designed for maximum generation on low-light and overcast UK days.

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 solar and 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 forecasts weather patterns to maximise savings.
• Smart Tariff Sync: Connects directly with dynamic off-peak tariffs (such as Octopus Flux, Intelligent Octopus Go, 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 solar generation, battery level, home usage, and savings live on your smartphone.

Estimated Annual Savings

• Estimated Bill Savings: £2,100 – £3,000+ per year (based on a high-consumption UK household utilising smart off-peak rates year-round alongside maximum solar self-consumption).
• Grid Reliance Reduction: Reduces annual mains grid electricity dependency by up to 90%–98%.
