30.72kWh 51.2V Floor Standing Lithium Battery with Modular Expansion
This 30.72kWh floor standing lithium battery provides a large low-voltage energy reserve for homes, farms, offices, shops and light commercial solar projects. Its 51.2V, 600Ah LiFePO4 configuration is intended for applications with higher daily consumption or extended backup requirements.
The product is supplied as a battery bank rather than a complete energy storage system. A compatible external inverter or PCS is required for solar charging, AC source coordination and load output.
The 30.72kWh nominal capacity can store a larger amount of daytime solar production or maintain energy for priority loads during an extended operating period. Suitable capacity should be calculated from the site’s actual daily kilowatt-hour demand.
A larger battery does not automatically increase AC output power. The external inverter determines how much equipment can operate simultaneously, while the battery capacity influences how long the selected loads can be supported.
A high-capacity battery should be paired with sufficient photovoltaic or AC charging power. The charging system should be able to replace the energy used during the available solar or utility charging window.
The battery has a rated charge and discharge current of 100A. Higher current references are listed as 200A continuous and 205A for 10 seconds. Actual settings should remain compatible with the inverter and electrical design.
RS485, RS232 and CAN interfaces support communication with compatible inverter equipment. Optional Bluetooth and WiFi monitoring can be selected according to project requirements.
Six batteries are recommended for common parallel arrangements, while up to sixteen units are supported. Larger banks require coordinated communication, protection equipment, cables and busbar capacity.
The cabinet measures 900 × 700 × 320mm and weighs approximately 224kg. Buyers should confirm the unloading route, doorway clearance, floor condition and final equipment position before delivery.
The IP21 enclosure requires a dry indoor or protected technical location. The side cable outlet should remain accessible for battery wiring and servicing.

Compare the site’s daily energy consumption, required reserve period, inverter losses and the percentage of battery energy intended for regular use.
Insufficient solar or AC charging power may prevent the battery from recovering the energy used within the available charging period.
Several communication interfaces are available, but the exact inverter model and supported battery protocol must be confirmed.
Confirm unloading equipment, access width, floor condition and the final protected installation position before shipment.
Yes. Parallel expansion is supported, subject to complete inverter, communication, cable and protection compatibility.
Send the daily energy demand, charging-source capacity and required reserve period. We will review whether the battery and inverter configuration match the project.
