Austrian Energy Storage Battery Company Recommendation – GSL Stacked Battery Installation

We are pleased to announce the successful commissioning of a stackable energy storage system featuring a 10kW Deye hybrid inverter paired with a 20kWh GSL Energy stackable battery storage solution for a private residence in Salzburg, Austria.

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

Energy autonomy
Cost efficiency
System resilience

With Austria experiencing substantial electricity price volatility—a 120% increase since 2021—and a national mandate for 100% renewable electricity by 2030, 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 Deye 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 GSL Energy battery system is composed of two 10kWh 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

GSL Energy 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
GSL's LiFePO₄ battery chemistry guarantees:
6,500+ cycles @ 80% DoD
Over 15 years of service life with minimal performance degradation

Conclusion & Recommendations
This Salzburg project demonstrates a replicable model for residential energy independence in mountainous regions. For homeowners considering similar systems, GSL Energy recommends:

Selecting components based on space and load requirements
Investigating local subsidies and incentives
Designing with future scalability in mind

GSL Energy is committed to delivering customized, modular, and scalable stackable energy storage solutions tailored to your unique needs.
