Dafa Solar pitches 5kWh wall-mounted LiFePO4 battery for home storage buyers

Dafa Solar is promoting a 5kWh, 51.2V wall-mounted LiFePO4 battery for residential energy storage, targeting distributors, installers and EPC contractors. The company says the pack is built for easier installation, inverter compatibility and long service life in home solar systems.

Why it matters: - The battery format is aimed at lowering installation labor and total operating cost for home energy storage projects. - The modular design lets buyers start with 5kWh and scale storage capacity as household demand grows. - The product is positioned for distributors, solar installers and EPC contractors that need faster deployment and simpler sourcing.

What happened: - Dafa Solar (Dawnice) published a commercial guide for a wholesale 5kWh wall-mounted LiFePO4 battery for home energy storage. - The battery uses a 51.2V 100Ah architecture and is described as a standard building block for residential photovoltaic systems. - The company provided a product page at More information. - Zhengzhou Treasure Box Import And Export Trade Co., Ltd. is listed in the release, along with the contact number +86 15803850181.

The details: - The battery uses grade-A lithium iron phosphate cells and a rigid internal structure with isolation barriers between cells. - The pack is designed for a 6,000-plus cycle lifespan. - The BMS supports voltage balancing, temperature monitoring and protection against over-voltage, over-discharge, short circuits, high-current spikes and low-temperature charging. - The management system supports RS485 and CANbus communication for closed-loop use with hybrid inverters from Deye, Growatt, Solis, Victron and SAJ. - The enclosure is IP65-rated, powder-coated steel with passive heat dissipation and no external fan requirement. - The wall-mounted form factor is described as slim, with a depth under 160mm. - The unit weighs 45kg to 50kg and uses separate wall plates and locking brackets for installation. - The company says the pack uses grade-A cell sorting and active balancing modules to preserve capacity and extend service life past 6,000 cycles at 80% depth of discharge. - Parallel ports support daisy-chaining and auto-addressing across multiple battery units. - The system supports up to 15 or 16 parallel units on a single low-voltage DC bus, for as much as 80kWh total storage. - Operating temperature is listed at -10°C to 50°C, with charging recommended above 0°C. - The battery should be secured to masonry, concrete or reinforced wall studs capable of supporting a 50kg static load.

Between the lines: - The release is built to address common pain points in residential storage sales, especially inverter communication failures, wall-mounting strain and early battery degradation. - The emphasis on protocol libraries, DIP switches and closed-loop communications suggests the company is targeting installers who want faster commissioning and fewer site troubleshooting calls. - The repeated focus on certifications, QC testing and shipping terms points to export buyers who need compliance documentation and predictable landed costs.

What's next: - Dafa Solar is steering buyers toward direct inquiries for product specifications, technical datasheets and commercial sourcing. - The company says it offers OEM and ODM customization, including branded enclosures, custom circuit breaker sizing and localized LCD displays. - Bulk buyers are expected to evaluate warranty terms, after-sales support, inverter compatibility and freight terms such as EXW, FOB and DDP before ordering.

The bottom line: - Dafa Solar is packaging a wall-mounted home battery as a plug-and-play, export-ready storage product with inverter compatibility, modular expansion and installer-friendly hardware.
