51.2V 5kWh 10kWh Rack Mounted LiFePO4 Battery for Residential Solar Energy Storage
51.2V 5kWh–16kWh Rack Mounted LiFePO4 Battery
Modular lithium battery solutions for residential solar storage, hybrid inverters, off-grid systems and backup power applications.
Rack-Mounted Battery Storage for Modern Solar Systems
The Chalongfly rack-mounted LiFePO4 energy storage battery series provides flexible battery capacity options for residential photovoltaic systems, home energy storage and compatible backup-power installations.
Designed around a 51.2V nominal low-voltage battery architecture, the series covers common 5kWh, 10kWh, 15kWh and 16kWh energy classes for different storage requirements.
Its rack-mounted structure supports organized battery integration, while smart BMS management and optional inverter communication interfaces help simplify system engineering and operation.
Energy Capacity Selection
Select the appropriate nominal battery energy according to photovoltaic generation, daily electricity consumption and required backup duration.
| Energy Class | Voltage | Reference Capacity | Nominal Energy |
|---|---|---|---|
| 5kWh Class | 51.2V | 100Ah | 5.12kWh |
| 10kWh Class | 51.2V | 200Ah | 10.24kWh |
| 15kWh Class | 51.2V | 300Ah | 15.36kWh |
| 16kWh Class | 51.2V | 314Ah | 16.08kWh |
Reference capacity configurations are subject to model availability and final technical approval. System energy may also be achieved through approved combinations of battery modules.
Rack-Mounted Installation
Rack-mounted battery storage is suitable for projects requiring organized power connections, communication wiring and service access within a dedicated energy storage cabinet or installation area.
| Installation Method | Rack Mounted |
| Rack Compatibility | Subject to Rack Width, Depth and Load Rating |
| Battery Fixing | According to Approved Mounting Design |
| Power Connection | Configured for Battery Current and System Layout |
| Communication | CAN / RS485 Available |
| Service Clearance | According to Battery Installation Requirements |
Intelligent Battery Management System
The integrated smart BMS supports battery protection, cell monitoring and energy-management functions for repeated charge and discharge operation.
Overcharge, over-discharge, over-current and short-circuit protection according to the selected BMS.
Cell voltage monitoring, battery temperature monitoring and balancing functions support controlled battery operation.
Available battery data include SOC, voltage, current, temperature and operating or alarm status, depending on the monitoring configuration.
CAN and RS485 Inverter Communication
Battery-to-inverter communication helps compatible systems coordinate charging, discharging and battery operating limits.
| CAN Interface | Available According to BMS Configuration |
| RS485 Interface | Available According to BMS Configuration |
| Modbus | Project-Dependent Protocol Option |
| Inverter Compatibility | Exact Inverter Model and Protocol Must Be Confirmed |
Communication port availability alone does not guarantee compatibility with every inverter. Protocol matching and charging parameters must be verified.
Modular Battery Capacity Expansion
Rack-mounted LiFePO4 battery systems can be engineered with multiple compatible battery modules to meet higher energy storage requirements.
The final expansion design depends on the battery BMS, communication architecture, inverter, protection devices and power distribution system.
Multi-module operation requires an approved battery configuration, correctly sized cables and busbars, coordinated protection devices and verified communication. The maximum number of modules must be confirmed for each project.
Solar Energy Storage and Home Backup
| Solar Self-Consumption Store surplus solar energy for use when photovoltaic generation is reduced. | Home Backup Power Provide stored battery energy to compatible backup inverters during power interruptions. |
| Off-Grid Solar Systems Support independent energy systems with suitable solar charging and inverter equipment. | Home ESS Cabinets Integrate compatible battery modules within organized rack-mounted energy storage installations. |
Battery-Only Storage Architecture
The product is supplied as a battery energy storage unit unless additional equipment is specifically included in the approved quotation.
Hybrid inverters, photovoltaic panels, solar charge controllers, AC distribution equipment and backup transfer equipment are selected separately according to the final system design.
Proper system protection, installation and commissioning must be completed by qualified personnel.
