France 64kWh Solar Battery Storage Case Study
4×16kWh Avepower LiFePO4 Batteries in Parallel
- Region: France
- Application: Residential
- System Size: 64kWh
- Nominal Voltage: 51.2V
- Battery Configuration: 4 × 16kWh
Project Overview
The customer needed a solar battery system with enough storage capacity to support daily energy use and provide backup power during outages or low solar production periods.
Solution
Avepower supplied four 16kWh LiFePO4 battery units for parallel installation, building a total battery capacity of 64kWh.
Each battery unit includes an integrated BMS to support battery protection, system monitoring, and stable operation. By connecting four battery units in parallel, the system increases total available energy storage while keeping the battery layout clean and serviceable.
Why Use 4×16kWh Batteries in Parallel?
A 4-unit parallel system gives the user more flexibility than relying on one large battery cabinet. It allows the storage system to be expanded step by step, simplifies transportation and placement, and makes maintenance more convenient.
Main Advantages:
- Higher total storage capacity
- Flexible system expansion
- Easier installation and handling
- Better backup power support
- Suitable for high-energy-use applications
- Modular design for future upgrades
Outcome
After installation, the customer received a 64kWh solar battery storage system built with four Avepower 16kWh LiFePO4 batteries in parallel.
The project delivered:
- Increased energy storage capacity
- Longer backup power availability
- Flexible parallel battery expansion
- Cleaner system integration with solar and inverter equipment
- Practical indoor installation for daily use and maintenance
- A scalable battery storage solution for solar energy applications
This case shows how Avepower low-voltage LiFePO4 batteries can be used to build a reliable, expandable solar battery storage system for residential and light commercial projects.
