Background:
A shopping complex in Germany was facing rising electricity costs and increasing demand for sustainable energy solutions. Their existing lead-acid battery system required frequent maintenance and had limited storage capacity.
Challenge:
The client needed a reliable, high-capacity energy storage solution that could integrate with their rooftop solar PV system and support peak load management during high-demand hours.
Solution:
We supplied a customized 48V 200Ah LiFePO4 battery system with a smart BMS (Battery Management System) and parallel connection capability to achieve a total capacity of 100kWh. The system was designed for easy installation and integrated seamlessly with the building’s existing solar inverter setup.
Results:
• Reduced electricity bills by 32% in the first year.
• Maintenance intervals extended from monthly to yearly.
• Improved system efficiency with 95% round-trip energy conversion rate.
Customer Feedback:
“The new LiFePO4 battery system not only lowered our operational costs but also supports our sustainability goals. Installation was smooth, and the performance is excellent.” — Facility Manager, Berlin
