51.2V 280Ah Rack Mounted Lithium Battery With CAN RS485 200A Continuous Current

51.2V 280Ah Rack Mounted Battery with CAN RS485 and 200A Continuous Current

A High-Current Rack Battery with Defined Integration Parameters

This 51.2V 280Ah rack mounted battery provides 14.336kWh of nominal LiFePO4 energy for compatible inverter and energy storage systems. Its technical focus includes a defined DC voltage range, 200A continuous charging capability, 200A continuous discharge capability and optional CAN or RS485 communication.

The battery should not be selected from capacity alone. The inverter’s voltage range, charge settings, maximum battery-side demand, communication protocol, DC protection and cable requirements must all be reviewed before connection.

An LCD provides access to supported local battery information. CAN and RS485 are optional interfaces, and successful communication depends on the exact inverter protocol, firmware, cable definition and system configuration.

Four Electrical Checks Before Inverter Connection

Using the 200A Charge and Discharge Ratings Correctly

The maximum continuous charging current is 200A. This value is a battery limit rather than a required charging setting. A lower current may be selected according to the inverter charger, available solar power, cable capacity and preferred charging time.

The maximum continuous discharge current is also 200A. The inverter’s battery-side current should be calculated at the lowest expected operating voltage and highest planned continuous AC load.

Battery cables, M8 terminals, fuses, breakers, disconnect devices and any intermediate busbars must be suitable for the configured continuous current. Cable length and conductor size should be planned to control voltage drop and heat.

The battery has a listed pulse-discharge capability of 300A for one second. This short-duration figure must not be treated as the continuous operating current or used to justify undersized DC components.

LCD Monitoring and BMS Protection

The LCD provides local access to supported battery operating information and can assist during commissioning and routine inspection. The exact displayed values depend on the battery configuration.

The battery-management system includes protection for overcharge, overdischarge, overcurrent, short-circuit and overtemperature conditions. These functions help keep operation within the documented electrical limits.

BMS protection does not replace external system protection. Correctly rated DC breakers, fuses, cables, disconnect devices and terminal connections remain necessary.

CAN RS485 Communication Requirements

Optional CAN or RS485 communication may allow supported battery information to be exchanged with a compatible inverter. The available data depends on the selected protocol and equipment configuration.

A matching communication-port name does not guarantee compatibility. The inverter brand, exact model, firmware, protocol and cable pin definition should be checked before the order is confirmed.

Electrical and Communication Specifications

200A CAN RS485 Rack Battery FAQ

Are CAN and RS485 included as standard?

No. They are optional communication interfaces and should be specified when the battery configuration is confirmed.

Will the battery communicate with every inverter?

No. The protocol, firmware, cable definition and equipment settings must be compatible with the exact inverter model.

Can the battery continuously charge and discharge at 200A?

The listed maximum continuous limits are 200A for charging and 200A for discharging. Final settings must also remain within the inverter, cable and protection ratings.

Does the 300A rating apply continuously?

No. The 300A value applies for one second only. The continuous discharge limit is 200A.

What information is required for inverter matching?

Provide the inverter brand, exact model, firmware, battery-voltage range, maximum charging current and supported CAN or RS485 protocol.

Current and Communication Compatibility Review

A pre-order review can confirm the inverter voltage range, charging settings, continuous battery demand, communication protocol and required interfaces.
