DYNAVOLT 51.2V 314Ah LiFePO4 Lithium Battery 16.08kWh

الوصف

, residential backup power, and compatible hybrid or off-grid inverter systems.

With a rated voltage of 51.2V and a nominal capacity of 314Ah, the battery provides 16.08kWh of nominal energy. This makes it suitable for applications that require a high-capacity lithium storage solution for solar power systems, backup loads, and energy storage installations where a 48V/51.2V battery platform is required.

The battery uses LiFePO4 chemistry, a widely adopted lithium battery technology for solar storage due to its stable performance and suitability for repeated charge and discharge cycles. The DYNAVOLT LB51314W includes a built-in BMS that provides warning and protection functions for over-discharge, over-charge, over-current, short-circuit, and high or low temperature conditions.

For system integration, the battery supports RS485, CAN, and RS232 communication interfaces. These ports allow communication with compatible inverters, monitoring systems, and battery management equipment. The manual also states that the system supports up to 15 batteries connected in parallel, allowing future expansion of storage capacity when the installation is correctly configured.

The battery supports a standard charge current of up to 100A and a maximum charge current of 200A. It also supports a standard discharge current of up to 100A and a maximum discharge current of 200A, subject to operating temperature, cable sizing, protection devices, and inverter compatibility. Proper system design is required to ensure safe and reliable operation.

According to the manual, the battery is intended to work as a storage unit in photovoltaic systems and can operate in on-grid, backup, and off-grid modes with compatible inverters. The system also supports Bluetooth local connection or 2.4GHz WiFi remote control through the lithium battery IoT cloud/app, depending on the configuration and available accessories.

The DYNAVOLT LB51314W is a suitable option for customers looking for a high-capacity 51.2V LiFePO4 battery with integrated BMS protection, multiple communication interfaces, parallel expansion support, and solar energy storage capability. Before installation, compatibility with the inverter, BMS protocol, charging parameters, protection devices, cable sizing, and local electrical requirements must be verified by a qualified technician.
