51.2V 50Ah Wall Mounted Lithium Battery with CAN RS485 and BMS Protection
This 51.2V 50Ah wall mounted lithium battery is designed for compatible solar inverters, residential backup systems and compact energy-storage installations. Its nominal battery energy is 2.56kWh, based on a 51.2V platform and 50Ah rated capacity.
The integrated battery-management system includes protection functions for overcharge, overdischarge, overcurrent, short-circuit and overtemperature conditions. These functions help manage the battery within its documented electrical and environmental operating limits.
Optional CAN and RS485 ports are available for compatible inverter communication. An optional LCD can also provide local access to available battery information at the installation site.
Multiple Protection Functions
The battery-management system monitors listed voltage, current, short-circuit and temperature conditions during operation.
Optional CAN and RS485
Communication interfaces can support compatible inverter integration after the protocol and connection requirements are confirmed.
75A Short Pulse Discharge
The battery can provide a one-second 75A pulse for compatible temporary current demand while its continuous limit remains 50A.
Optional LCD Display
The optional display can provide installers and operators with convenient local access to supported battery operating information.
The presence of CAN or RS485 ports does not mean that the battery can communicate with every inverter. Both devices must use a compatible protocol, correct cable pin assignment and suitable software settings.
When communication compatibility is not confirmed, installers should not assume that automatic charging control, state-of-charge reporting or battery alarms will be exchanged with the inverter.
The inverter must operate within the battery’s 40.0–58.4Vdc voltage range and support the listed 56.0V floating-charge voltage. The maximum continuous charging current should be limited to 25A.
Continuous discharge is limited to 50A. The 75A rating is a one-second pulse specification and should not be used as the continuous-current value when selecting the inverter, cables or protective devices.
Communication ports and the LCD are listed as optional. The required hardware configuration and inverter protocol should be confirmed before the purchase order is finalized.

The parameter table identifies the communication ports as optional. Their inclusion should be confirmed before ordering.
No. Compatible communication requires a supported protocol, correct cable wiring and matching settings on both devices.
The listed protections cover overcharge, overdischarge, overcurrent, short-circuit and overtemperature conditions.
No. The LCD is identified as an optional configuration and should be specified in the order requirements.
It means the battery can provide up to 75A for one second. Its maximum continuous discharge current remains 50A.
This wall mounted lithium battery is suitable for distributors and installers requiring a compact 51.2V storage product with documented protection functions and optional inverter communication.
