Product Description
The BPEL512100W is a 51.2V nominal (16S LiFePO4 configuration), 100Ah wall-mounted battery module designed specifically for solar self-consumption and off-grid backup applications. Rated energy output: 5,120Wh.
Unlike many competing units on the market that use blended or refurbished cells, every BPEL512100W module uses Grade A prismatic LiFePO4 cells sourced from tier-1 cell manufacturers. Internal resistance is held to ≤10mΩ at pack level — a number that directly correlates with heat generation, efficiency loss, and long-term capacity retention.
The unit ships in a metal case (750×450×163mm, 55kg) with an IP67 ingress protection rating, making it viable for garage, utility room, or sheltered outdoor wall-mount installations. A built-in display screen provides real-time SOC, voltage, and fault status without requiring an external monitoring device.

Features & Advantages
✅ 6,000+ Cycle Life — Real-World Durability, Not Lab Numbers
Tested at 80% DOD per IEC standard cycles. At one full cycle per day, that is 16+ years of calendar life. LiFePO4 chemistry eliminates thermal runaway risk that NMC or NCA chemistries carry — critical for enclosed wall-mount environments.
✅ IP67-Rated Metal Enclosure — Built for Real Installations
Full dust-tight and short-duration water immersion protection. The metal case provides structural rigidity for wall-bracket mounting and adds a layer of passive thermal mass. Dimensions: 750×450×163mm. Net weight: 55kg. Plan for a two-person installation.
✅ Multi-Protocol BMS — Works With Your Inverter Out of the Box
Integrated BMS communicates via CAN, RS485, and RS232 simultaneously. Compatible with Growatt, Deye, Victron, SolarEdge, Luxpower, and other mainstream hybrid inverters without protocol conversion hardware. Charge mode: CC/CV (0.2C → 58.4V, taper to 0.05C). Max continuous charge/discharge: 100A each. Peak pulse: 150A.
✅ Parallel Scalability Up to 30 Units
Stack up to 30 modules in parallel for a maximum system capacity of **153.6kWh** — enough to cover small commercial loads or large residential off-grid setups. No additional communication hub required for basic parallel operation.
✅ Wide Operating Temperature Range
Discharge operational from **-20°C to 60°C** (-4°F to 140°F). Charge range: 0°C to 45°C. This makes the unit deployable in Northern European winters and Middle Eastern summers without derating.
✅ Certified for International B2B Shipments
Holds **UN38.3, MSDS, and CE** certifications. Documentation package for customs clearance, Amazon FBA, or distributor import requirements is available on request. Air freight, sea freight, and courier-compatible with proper MSDS declaration.
✅ OEM/ODM — Your Brand, Your Specs
We accept custom voltage configurations, capacity adjustments, enclosure color and labeling, BMS protocol additions (e.g., Modbus RTU), and third-party certifications (UL, IEC 62619). Engineering review turnaround: 3–5 business days. Sample lead time: 15–20 days. Production MOQ and pricing available upon NDA signing.

FAQ
Q1: What is the actual usable capacity of the BPEL512100W at 80% DOD? A: At 80% depth of discharge, the usable energy is approximately 4,096Wh (4.1kWh). For system sizing, we recommend calculating daily load against this figure rather than the rated 5.12kWh to preserve cycle life.
Q2: How many charge-discharge cycles does a LiFePO4 wall battery last? A: The BPEL512100W is rated for over 6,000 cycles at 80% DOD. At one cycle per day, that translates to roughly 16 years of operational life — significantly longer than NMC chemistries, which typically rate 1,500–3,000 cycles under comparable conditions.
Q3: Which inverter brands is this 51.2V 100Ah battery compatible with? A: The integrated BMS supports CAN, RS485, and RS232 communication protocols. It communicates natively with Growatt, Deye (Sunsynk), Victron MultiPlus/Quattro, Luxpower, and SolarEdge StorEdge systems. For Modbus RTU or proprietary protocol requirements, contact us for a compatibility assessment before ordering.
Q4: What is the minimum order quantity (MOQ) for wholesale buyers? A: Standard MOQ is 10 units for stocked configurations. For OEM/ODM orders with custom branding, enclosure color, or BMS protocol modifications, MOQ starts at 50 units. Sample orders (1–2 units) are accepted for qualification testing — sample lead time is 7–10 business days.
Q5: What certifications does this battery hold for international import? A: The BPEL512100W holds UN38.3 (transport safety), MSDS, and CE (EU market compliance). A full documentation package including test reports is available upon request. If your market requires UL 9540, IEC 62619, or additional regional certifications, we can arrange third-party testing as part of an OEM engagement.
Q6: Can multiple units be connected in parallel, and how is it wired? A: Yes. Up to 30 units can be connected in parallel using the same bus bar configuration, giving a maximum system capacity of 153.6kWh. Units must be within 10% SOC of each other before parallel connection. CAN bus daisy-chain is used for BMS coordination across the stack. Wiring diagrams and system integration guides are provided with every order.
