Scalable 60kWh Lithium Storage Solution with SunWell Compatibility

In 2024, SunWell Energy successfully deployed a 60kWh wall-mounted lithium battery system for a residential & small commercial client in the United States. The solution utilizes six 10kWh 51.2V LiFePO4 battery units connected in parallel and fully integrated with an SunWell hybrid inverter. This project showcases the flexibility, safety, and certified quality of SunWell’s wall-mounted battery series, which is now widely adopted in the U.S. for both on-grid and off-grid applications.
