Product Overview
This 15.36kWh solar battery is designed for residential and off-grid energy storage applications that require higher storage capacity within a 51.2V battery platform.
The battery uses LiFePO4 cells with a rated capacity of 300Ah and an operating discharge voltage range of 43.2–58.4V. Standard charging current is 100A, while maximum charging and discharging current are both rated at 200A.
An integrated battery management system provides battery protection and operating management, while CAN and RS485 communication interfaces allow the battery to communicate with compatible inverter and energy storage equipment.
What Buyers Usually Need to Confirm
Before quotation or system configuration confirmation, buyers normally need to confirm:
- required battery capacity and number of battery units
- inverter brand and model
- inverter battery-voltage requirements
- CAN or RS485 communication requirements
- required charging and discharging current
- expected daily energy consumption and backup duration
- solar PV and inverter system configuration
- OEM / branding requirements if applicable
- quantity and destination market
If the inverter has already been selected, buyers can send the inverter model and system configuration for battery communication and parameter checking before quotation.

Battery Management & Communication
The battery is equipped with a battery management system for charging, discharging, and battery protection. CAN and RS485 interfaces are provided for communication with compatible inverter systems.
Because communication protocols and battery settings can differ between inverter platforms, the inverter model and required communication method should be checked before the battery and inverter are ordered as a system.

For a matching 48V-class off-grid power solution, see our 6kW / 12kW 48V Off-Grid Solar Inverter.
For this 15.36kWh battery configuration, the 6kW inverter option is particularly relevant to the recommended system range provided for the current battery configuration. The inverter model, charging settings, battery communication, PV array, and load requirements should still be confirmed together before ordering.
