This project involved a gas-free private residence, where the primary requirement was to ensure reliable backup power without the use of diesel generators. The system was designed to support essential household loads and a heat pump while remaining fully prepared for future solar integration.
System Configuration
- Hybrid single-phase inverter – 12 kW
- Battery storage – 2 × 5 kWh LiFePO₄ (low-voltage)
- Backup autonomy up to 10 hours (depending on load profile)
- Heating – heat pump supported by the system
- Electric boiler intentionally excluded from the inverter circuit, as requested by the client
Results
- During grid outages, the house remains fully operational.
- Lighting, sockets, networking equipment (Wi-Fi), and critical household systems remain powered for up to 10 hours, while the heat pump maintains indoor comfort.
- The system operates silently, without emissions, noise, or manual intervention.
Future Expansion
The system was intentionally designed with a solar-ready architecture.
In spring 2026, the client plans to add:
- rooftop solar PV
- an additional 10 kWh of battery storage
This will significantly increase self-consumption and overall energy autonomy.
Key Benefits for the Homeowner
- Up to 10 hours of silent backup power
- No reliance on diesel generators
- Safe, long-life LiFePO₄ battery technology
- Modular design enabling future expansion
- Improved energy resilience and comfort
