Dyness Powerbox G2 – 10.24 kWh Low-Voltage Battery (51.2 V)

The Dyness Powerbox G2 is a residential LiFePO₄ home battery designed for safety, long cycle life, and flexible mounting (floor or wall). With IP65 protection and integrated intelligence (BMS, fire-safety module and optional heating), the G2 is suitable for daily cycling, backup power and maximizing self-consumption of solar energy.

Key benefits

• 10.24 kWh per unit; scalable to large systems via parallel connection.
• LiFePO₄ chemistry for high safety, stable performance and long life.
• IP65 enclosure for indoor or outdoor placement; floor or wall mounting.
• Intelligent BMS with active protection and status monitoring.
• Integrated safety features including fire detection/suppression and low-temperature support.
• Communication via CAN/RS485; broad inverter compatibility.

Applications

• Maximize self-consumption with solar PV (store daytime surplus, use at night).
• Backup power for critical circuits during grid outages.
• Peak shaving and time-of-use shifting with dynamic tariffs.
• Modular expansion for larger households or small commercial needs.
