5.12 kWh wall-mounted LiFePO4 home battery, 51.2V 100Ah, smart BMS, CAN/RS485 and hybrid inverter compatible.

SKU: YD-RS-5K

Category: Residential Energy Storage

Description

5.12 kWh Wall-Mounted Home Battery (51.2 V 100 Ah) is a LiFePO4 home energy storage system for solar self-consumption and backup power. The wall-mounted 5.12 kWh unit is the standard single-phase home battery, sized to cover evening loads and short outages for a typical household. The system provides 5.12 kWh of nominal energy at 51.2 V using 16S1P architecture and is designed for wall-mounted installation.

Battery & BMS Technology

The system uses grade-A prismatic LiFePO4 cells and a multi-level BMS that performs cell balancing, cell voltage and temperature monitoring, over-charge and over-discharge protection, over-current and short-circuit protection, and state-of-charge and state-of-health estimation. Communication is provided over CAN / RS485, Bluetooth optional, with a display or app interface for monitoring, and dry contacts for generator or load control.

Safety & Cycle Life

LiFePO4 cells deliver more than 6,000 cycles at 80% depth of discharge under typical residential daily cycling. The battery operates between -20 °C and +60 °C, the enclosure is rated IP20, and protection features include insulation monitoring, cell over-voltage and under-voltage cut-off and short-circuit isolation.

Charging & Inverter Compatibility

The system is charged by a hybrid or off-grid inverter at a recommended 50 A rate, with charge voltage set to 58.4 V. It is compatible with mainstream hybrid and off-grid inverters through standard CAN or RS485 protocols, and supports time-of-use scheduling, peak shaving, self-consumption maximisation and off-grid operation. Up to 8 units can be connected in parallel to reach 40.96 kWh for larger homes, using the supplied parallel communication cables.

Mechanical & Installation

The enclosure is powder-coated steel wall cabinet measuring 540 × 480 × 150 mm and weighing approximately 48 kg. The cabinet mounts on a wall or on an optional floor stand, with a maintenance clearance of 300 mm on both sides and 500 mm at the front. Terminal covers, cable glands and breaker provisions are included, and installation follows the supplied commissioning guide.

Typical Use Cases

Installed in single-family homes with 3-6 kW rooftop solar arrays, in shops and small clinics that need outage protection, and in weak-grid areas where daily load shedding is common.

Customisation

Capacity, cabinet colour, brand labelling, terminal type, protocol mapping and packaging can be customised for distributors, EPC contractors and installer networks. Firmware parameters, inverter compatibility lists and technical documentation are supplied in English. Larger capacities than the standard range are available on a project basis.

Factory battery module range

Storage systems are built from the following battery modules, with the system capacity configured per project:

Model	Chemistry	Nominal voltage	Nominal capacity
YD-48-100	LiFePO4	51.2 V	100 Ah
YD-48-200	LiFePO4	51.2 V	200 Ah
YD-48-280	LiFePO4	51.2 V	280 Ah
YD-48-314	LiFePO4	51.2 V	314 Ah
YD-48-942	LiFePO4	51.2 V	942 Ah

Other models are customised: storage cabinets from 5–200 kWh, and commercial and industrial storage from 200–5000 kWh.

Every system is capacity-tested and communication-tested before shipment. Compliance target standards: UN38.3, IEC 62619, CE and RoHS. Warranty: 5 years, extendable to 8 years.

FAQ

Buyer FAQ

These answers match the sitewide terms and the quality page. Where a quotation differs, the quotation governs.

What is the minimum order quantity?

MOQ is 20 units per model. Single units are available as paid evaluation samples, and that cost is credited against your first production order.

What is the lead time?

Standard configurations ship 25 days after the deposit clears. Custom ratings, custom enclosures or multi-model orders carry the delivery date written into the quotation.

How do I pay?

Payment is by T/T. The deposit and balance proportions are written into the quotation before anything is produced.

Which standards and certificates apply?

Target standards are UN38.3, IEC 62619, CE and RoHS. LVD / EMC conformity is held under UDEM certificate M.2026.206.C143410, valid until 2031-06-29 and covering YD-24-314, YD-48-314 and YD-80-340. The certificate status that applies to your model is confirmed in writing with the quotation.

Certification table on the quality page

What documents ship with the goods?

Packing list, invoice, MSDS, UN38.3 summary report, dangerous goods declaration and the bill of lading, plus the datasheet and the factory inspection record for each unit. Packaging follows UN3480 / UN3481 and HS code 8507.60 applies. The port of loading is confirmed at quotation.
