We are pleased to announce the successful commissioning of a stackable energy storage system featuring a 10kW SolarEast hybrid inverter paired with a 20kWh SolarEast Battery Energy Storage System stackable battery storage solution for a private residence in Bavaria, Germany.
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 SolarEast Battery Energy Storage 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
SolarEast Battery Energy Storage System Technology Advantages
1. Climate-Adapted Design
Proprietary thermal management ensures stable performance across Austria's extreme climate conditions without added energy overhead.
2. Long-Term Value
SolarEast's LiFePO₄ battery chemistry guarantees:
6,500+ cycles @ 80% DoD
Over 15 years of service life with minimal performance degradation
