Project Background

With the increasing adoption of solar energy in Europe, more households are installing energy storage systems to improve energy independence and reduce electricity costs.

A residential customer in Germany contacted us for a reliable battery solution to store excess solar energy generated from their rooftop photovoltaic system.

Customer Requirements

• Store solar energy for night use
  
• Reduce electricity bills
  
• High safety standard for home use
  
• Long service life
  
• Compact and wall-mounted design

Our Solution

We recommended a 10kWh wall-mounted LiFePO4 battery system, designed for residential energy storage applications.

The system includes:

• High-quality LiFePO4 battery cells
• Built-in intelligent BMS (Battery Management System)
• Compatibility with mainstream inverters
• Modular design for future expansion

Installation and Application

The battery system was installed in the customer’s garage and connected to the rooftop solar inverter.

During the day, excess solar energy is stored in the battery, and at night, the stored energy is used to power household appliances.

Results

After installation, the customer achieved:

• Increased self-consumption of solar energy
• Reduced electricity costs
• Stable and reliable home power supply
• Quiet and maintenance-free operation

Conclusion

LiFePO4 home energy storage systems provide an efficient and safe solution for residential solar applications, helping users maximize solar energy usage and improve energy independence.
