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.
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.
Application illustration. The external inverter and installation accessories are shown for context; included items are defined in the quotation.
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.
Concept diagram for product selection, not an installation wiring drawing. Final protection, isolation, earthing, cabling and operating modes are specified for the selected inverter and project.

| Number of batteries | Combined total energy | Combined usable energy |
|---|---|---|
| 1 | 5.12 kWh | 4.6 kWh |
| 2 | 10.24 kWh | 9.2 kWh |
| 3 | 15.36 kWh | 13.8 kWh |
| 4 | 20.48 kWh | 18.4 kWh |
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.
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.
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.
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.
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.
The specified protection rating is IP20. Plan a suitable dry indoor installation and follow the model-specific installation requirements.
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.
