Rack Mounted Home Energy Storage Battery Systems 5.12 KWh LiFePO4 Residential ESS

RESIDENTIAL ENERGY STORAGE · 19-INCH RACK BATTERY

5.12 kWh of Modular Storage for Home Energy Systems

The YINTU YT-Racked ESS-5kWh is a low-voltage LiFePO4 battery module for residential energy storage. Each module provides 5.12 kWh nominal energy, 51.2 V nominal voltage and 100 Ah capacity in a standard 19-inch rack format. Its front LCD provides local battery information, while RS485, RS232 and CAN interfaces support communication with suitably matched equipment.

This is a DC battery module. A compatible external inverter is required to connect storage to household AC loads. Solar charging also requires a suitable external solar inverter or charge controller. YINTU supports product selection and system configuration in coordination with qualified manufacturing partners.

Key Product Features

• Defined energy per module: 5.12 kWh nominal capacity makes the starting storage size clear when planning a rack configuration.
• Standard rack format: 19-inch width and 133 mm module height help installers plan equipment layout, support rails and service access.
• Local status visibility: an integrated LCD displays battery information at the installation site.
• Communication options: RS485, RS232 and CAN interfaces are provided; the exact inverter protocol must be checked before selection.
• Two distinct current ratings: 50 A is the recommended charge/discharge current; 100 A is the maximum continuous charge/discharge current.
• Parallel configuration potential: the datasheet shows parallel-connected modules. The permitted module count and connection requirements must be confirmed for the proposed system.

Residential Applications

Consider this module for indoor residential solar storage, essential-load backup systems, and installer projects that use a rack-based battery layout. Solar self-consumption and backup operation depend on the selected inverter, system controls and installation design. The battery alone does not provide AC output or determine household backup power.

Illustrative installation. Rack, inverter, cabling and accessories are subject to the agreed supply scope.

How the Battery Fits into a Solar System

PV panels connect to the compatible external solar inverter. The rack battery connects to the inverter through its battery DC interface, with an appropriate BMS communication connection. The inverter converts stored energy to AC for the selected household loads. Grid connection, charging permissions and backup circuits follow the capabilities of the chosen inverter and local installation requirements.

The diagram explains the system concept and is not an installation wiring drawing. Confirm battery voltage compatibility, communication protocol, inverter battery-current limits, protection devices and the final wiring design for each project.

Electrical Specifications

Nominal energy describes the battery rating. Deliverable AC energy and operating time depend on the allowed state-of-charge range, inverter losses, load profile, temperature and system settings. The datasheet does not specify a usable-energy value.

Mechanical and Environmental Specifications

Plan a dry, protected indoor location suitable for the IP20 enclosure. Check rack depth, module support, cable space, cooling clearance and the combined weight of the complete assembly before installation.

Controls, Service Life and Documentation

[1] The datasheet states “70% EOF”; the cycle-life endpoint and complete test conditions require confirmation. This listing does not substitute a different endpoint definition.
[2] Standards are reproduced as listed in the supplied datasheet. The EMC designation “IEC610000-6-2/3” requires checking against the test report. Request model-specific certificates and reports to confirm applicability for the destination market.

Parallel Capacity Planning

The datasheet illustrates four modules in parallel, with 5.12 kWh per module. Four modules therefore represent 20.48 kWh of combined nominal energy by calculation. This example is not a stated maximum module count or a guarantee of a particular system power rating.

YINTU can help confirm the supported parallel arrangement, BMS settings, communication topology, cable and protection requirements, and inverter compatibility before the configuration is finalized. Later expansion should follow the approved manufacturer procedure and module-matching requirements.

Frequently Asked Questions

Is 5.12 kWh the energy of one module or the whole illustrated rack?

It is the nominal energy of one module. The multi-module illustrations show an example arrangement and do not change the per-module rating.

Can I connect solar panels or AC appliances directly to this battery?

No. Use a compatible external inverter and the required solar charging equipment. Confirm the complete equipment and protection arrangement for the installation.

Which current rating should be used?

The datasheet recommends 50 A for charging and discharging and lists 100 A as the maximum continuous current. The actual system setting must also respect the inverter, wiring, protection and operating-condition limits.

Is it compatible with every 48 V or 51.2 V inverter?

Compatibility is not established by the nominal voltage alone. Confirm the complete operating voltage range, communication protocol, current limits and approved configuration for the exact inverter model.
