Slim Enclosures Residential Energy Storage Systems 5.12 kWh for Solar Storage Solutions

5.12 kWh Home Battery for Flexible Solar Storage

SmartPack-SFL5A is a compact 51.2 V LiFePO4 battery for residential energy storage projects. It provides 5.12 kWh total energy and 4.6 kWh usable energy in a slim enclosure that supports floor-standing or wall-mounted installation. Pair it with a compatible external hybrid inverter to build a home solar storage solution suited to the household's energy use.

YINTU is an energy storage solution provider. We help customers select suitable products from capable manufacturing partners, coordinate battery and inverter matching, and define the supply configuration for their project.

Key Benefits

• Practical residential storage: 4.6 kWh usable energy supports storage planning for everyday household needs. Actual runtime depends on the connected loads, conversion losses and operating settings.
• Slim installation format: The 180 mm deep enclosure can stand on a suitable floor or use a verified wall-mounting arrangement, giving installers flexibility in a dry indoor equipment area.
• Expandable battery energy: Up to four units can be connected in an approved parallel configuration to increase stored energy as project requirements grow.
• LFP chemistry and stated cycle life: The datasheet lists at least 6000 cycles. Confirm the applicable depth of discharge, temperature, current and end-of-life criteria for the proposed supply configuration.
• Convenient operation and communication: One-button operation, a front display and CAN / RS485 / RS232 interfaces support system operation and integration.

Typical Home Application

Suitable project scenarios include residential solar self-consumption, energy storage for homes with variable daytime and evening demand, and selected-load backup when paired with an inverter that provides the required backup function. The IP20 battery should be installed in a suitable dry indoor location, with access, support and clearances determined from the installation manual.

How the Battery Fits into a Solar System

PV panels feed the external hybrid inverter. The inverter manages energy conversion and charges or discharges the battery through its DC battery connection. Battery management communication must match the inverter's supported protocol and firmware. Selected household loads connect through the appropriate AC circuits; grid connection and metering follow the agreed system design.

Electrical Specifications

The 100 A value is the maximum charging/discharging current stated in the datasheet; it is not specified as a continuous rating. Use the 50 A rated current and 2.56 kW rated power for initial selection. Operating current may be derated; confirm permitted limits and conditions for the final configuration.

Mechanical and Environmental Specifications

Values are taken from the supplied SmartPack-SFL5A datasheet and are subject to the manufacturer's final specification. Standards and documents above are listed in that datasheet; request the applicable model-specific certificates or reports for the destination market.

Parallel Energy Options

Combined energy values are calculated from the single-unit datasheet ratings. Parallel operation requires compatible units, an approved connection arrangement and a matched inverter. These energy figures do not establish the system's AC output power.

Selection and Supply Support from YINTU

Share the inverter brand and exact model, country, target usable energy, expected loads, installation space and order quantity. YINTU can coordinate product matching, technical documents and a project-specific quotation with the relevant manufacturing partners.

Before ordering, confirm inverter compatibility, communication settings, supplied mounting hardware, power and communication cables, warranty terms and delivery arrangements. The battery, inverter, PV equipment and site installation should be itemized in the quotation.

Frequently Asked Questions

Can solar panels connect directly to this battery?

No. Solar panels connect to a suitable external inverter or charge-control system. This battery does not provide an integrated PV inverter or AC output.

Can I use it with any 48 V inverter?

Compatibility is model-specific. The inverter must support the battery's operating voltage, charging and discharging limits, communication protocol and required settings. Confirm the pairing before purchase.

Does the battery support monitoring?

The datasheet describes remote diagnosis and real-time monitoring. Confirm the required inverter, gateway, platform and supplied accessories for the proposed system; built-in Wi-Fi is not specified in the interface table.

Can it be installed outdoors?

The specified protection rating is IP20. Plan a suitable dry indoor installation and follow the model-specific installation requirements.

How much storage can I build with this model?

The datasheet allows up to four units in parallel, giving a calculated total energy of 20.48 kWh and usable energy of 18.4 kWh. Final performance depends on the approved battery configuration and inverter.
