The homeowner sought a comprehensive energy solution with three core objectives:

Energy autonomy

Cost efficiency

System resilience

With Germany experiencing substantial electricity price volatility—and a national mandate for 100% renewable electricity by 2038, the client required a system capable of:

Maximizing solar self-consumption

Providing reliable backup power during grid outages

Performing reliably in Alpine temperatures ranging from -20°C to 35°C

Technical Solution Design

The installed system is built on a smart energy management architecture:

The 10kW SolarEast hybrid inverter functions as the system's control hub, managing energy flows between a 12kW PV array, the stackable battery modules, and the grid. It operates with 98% conversion efficiency.

The 20 kWh System is composed of four 5kWh stackable LiFePO₄ modules, providing a compact and modular design.

Key Technical Advantages:

Seamless switch between grid-tied and off-grid operation

Intelligent Battery Management System (BMS) maintains optimal battery temperature

Expandable architecture supporting upgrades to 160 kWh capacity

The system operates in three modes:

Solar Priority Mode – prioritizes real-time solar consumption

Storage Optimization Mode – enables time-of-use arbitrage

Emergency Backup Mode – automatically switches to off-grid during power outages
